7 \index[general]{FileSet Resource}
9 The FileSet resource defines what files are to be included or excluded in a
10 backup job. A {\bf FileSet} resource is required for each backup Job. It
11 consists of a list of files or directories to be included, a list of files
12 or directories to be excluded and the various backup options such as
13 compression, encryption, and signatures that are to be applied to each
16 Any change to the list of the included files will cause Bacula to
17 automatically create a new FileSet (defined by the name and an MD5 checksum
18 of the Include/Exclude contents). Each time a new FileSet is created,
19 Bacula will ensure that the next backup is always a Full save.
21 Bacula is designed to handle most character sets of the world,
22 US ASCII, German, French, Chinese, ... However, it does this by
23 encoding everything in UTF-8, and it expects all configuration files
24 (including those read on Win32 machines) to be in UTF-8 format.
25 UTF-8 is typically the default on Linux machines, but not on all
26 Unix machines, nor on Windows, so you must take some care to ensure
27 that your locale is set properly before starting Bacula.
28 On most modern Win32 machines, you can edit the conf files with {\bf
29 notebook} and choose output encoding UTF-8.
31 To ensure that Bacula configuration files can be correctly read including
32 foreign characters the {bf LANG} environment variable
33 must end in {\bf .UTF-8}. An full example is {\bf en\_US.UTF-8}. The
34 exact syntax may vary a bit from OS to OS, and exactly how you define
37 Bacula assumes that all filenames are in UTF-8 format on Linux and
38 Unix machines. On Win32 they are in Unicode (UTF-16), and will
39 be automatically converted to UTF-8 format.
46 \index[dir]{Directive!FileSet}
47 Start of the FileSet resource. One {\bf FileSet} resource must be
48 defined for each Backup job.
50 \item [Name = \lt{}name\gt{}]
52 \index[dir]{Directive!Name}
53 The name of the FileSet resource. This directive is required.
55 \item [Ignore FileSet Changes = \lt{}yes\vb{}no\gt{}]
56 \index[dir]{Ignore FileSet Changes}
57 \index[dir]{Directive!Ignore FileSet Changes}
58 Normally, if you modify the FileSet Include or Exclude lists,
59 the next backup will be forced to a Full so that Bacula can
60 guarantee that any additions or deletions are properly saved.
62 We strongly recommend against setting this directive to yes,
63 since doing so may cause you to have an incomplete set of backups.
65 If this directive is set to {\bf yes}, any changes you make to the
66 FileSet Include or Exclude lists, will not force a Full during
69 The default is {\bf no}, in which case, if you change the Include or
70 Exclude, Bacula will force a Full backup to ensure that everything is
73 \item [Enable VSS = \lt{}yes\vb{}no\gt{}]
74 \index[dir]{Enable VSS}
75 \index[dir]{Directive!Enable VSS}
76 If this directive is set to {\bf yes} the File daemon will be notified
77 that the user wants to use a Volume Shadow Copy Service (VSS) backup
78 for this job. The default is {\bf yes}. This directive is effective
79 only for VSS enabled Win32 File daemons. It permits a consistent copy
80 of open files to be made for cooperating writer applications, and for
81 applications that are not VSS away, Bacula can at least copy open files.
82 The Volume Shadow Copy will only be done on Windows drives where the
83 drive (e.g. C:, D:, ...) is explicitly mentioned in a {\bf File}
85 For more information, please see the
86 \ilink{Windows}{VSS} chapter of this manual.
89 \item [Include \{ Options \{\lt{}file-options\gt{}\} ...;
90 \lt{}file-list\gt{} \} ]
91 \index[dir]{Include \{ [ Options \{\lt{}file-options\gt{}\} ...]
92 \lt{}file-list\gt{} \} }
93 \index[dir]{Directive!Include}
95 \item [Options \{ \lt{}file-options\gt{} \} ]
96 \index[dir]{Options \{ \lt{}file-options\gt{} \} }
98 \item [Exclude \{ \lt{}file-list\gt{} \}]
99 \index[dir]{Exclude \{ \lt{}file-list\gt{} \} }
100 \index[dir]{Directive!Exclude}
105 The Include resource must contain a list of directories and/or files to be
106 processed in the backup job. Normally, all files found in all
107 subdirectories of any directory in the Include File list will be backed up.
108 Note, see below for the definition of \lt{}file-list\gt{}.
109 The Include resource may also contain one or more Options resources that
110 specify options such as compression to be applied to all or any subset of
111 the files found when processing the file-list for backup. Please see
112 below for more details concerning Options resources.
114 There can be any number of {\bf Include} resources within the FileSet, each
115 having its own list of directories or files to be backed up and the backup
116 options defined by one or more Options resources. The {\bf file-list}
117 consists of one file or directory name per line. Directory names should be
118 specified without a trailing slash with Unix path notation.
120 Windows users, please take note to specify directories (even c:/...) in
121 Unix path notation. If you use Windows conventions, you will most likely
122 not be able to restore your files due to the fact that the Windows
123 path separator was defined as an escape character long before Windows
124 existed, and Bacula adheres to that convention (i.e. \\ means the next character
127 You should always specify a full path for every directory and file that you
128 list in the FileSet. In addition, on Windows machines, you should {\bf
129 always} prefix the directory or filename with the drive specification
130 (e.g. {\bf c:/xxx}) using Unix directory name separators
131 (forward slash). The drive letter itself can be upper or lower case (e.g.
134 Bacula's default for processing directories is to recursively descend in
135 the directory saving all files and subdirectories. Bacula will not by
136 default cross filesystems (or mount points in Unix parlance). This means
137 that if you specify the root partition (e.g. {\bf /}), Bacula will save
138 only the root partition and not any of the other mounted filesystems.
139 Similarly on Windows systems, you must explicitly specify each of the
140 drives you want saved (e.g.
141 {\bf c:/} and {\bf d:/} ...). In addition, at least for Windows systems, you
142 will most likely want to enclose each specification within double quotes
143 particularly if the directory (or file) name contains spaces. The {\bf df}
144 command on Unix systems will show you which mount points you must specify to
145 save everything. See below for an example.
147 Take special care not to include a directory twice or Bacula will backup
148 the same files two times wasting a lot of space on your archive device.
149 Including a directory twice is very easy to do. For example:
154 Options { compression=GZIP }
161 on a Unix system where /usr is a subdirectory (rather than a mounted
162 filesystem) will cause /usr to be backed up twice.
164 Please take note of the following items in the FileSet syntax:
167 \item There is no equal sign (=) after the Include and before the opening
168 brace (\{). The same is true for the Exclude.
169 \item Each directory (or filename) to be included or excluded is preceded by a {\bf File
170 =}. Previously they were simply listed on separate lines.
171 \item The options that previously appeared on the Include line now must be
172 specified within their own Options resource.
173 \item The Exclude resource does not accept Options.
174 \item When using wild-cards or regular expressions, directory names are
175 always terminated with a slash (/) and filenames have no trailing slash.
178 The Options resource is optional, but when specified, it will contain a
179 list of {\bf keyword=value} options to be applied to the file-list.
180 See below for the definition of file-list.
181 Multiple Options resources may be specified one after another. As the
182 files are found in the specified directories, the Options will applied to
183 the filenames to determine if and how the file should be backed up. The
184 wildcard and regular expression pattern matching parts of the
185 Options resources are checked in the order they are specified in the
186 FileSet until the first one that matches. Once one matches, the
187 compression and other flags within the Options specification will
188 apply to the pattern matched.
190 A key point is that in the absence of an Option or no other Option is
191 matched, every file is accepted for backing up. This means that if
192 you want to exclude something, you must explicitly specify an Option
193 with an {\bf exclude = yes} and some pattern matching.
195 Once Bacula determines that the Options resource matches the file under
196 consideration, that file will be saved without looking at any other Options
197 resources that may be present. This means that any wild cards must appear
198 before an Options resource without wild cards.
200 If for some reason, Bacula checks all the Options resources to a file under
201 consideration for backup, but there are no matches (generally because of wild
202 cards that don't match), Bacula as a default will then backup the file. This
203 is quite logical if you consider the case of no Options clause is specified,
204 where you want everything to be backed up, and it is important to keep in mind
205 when excluding as mentioned above.
207 However, one additional point is that in the case that no match was found,
208 Bacula will use the options found in the last Options resource. As a
209 consequence, if you want a particular set of "default" options, you should put
210 them in an Options resource after any other Options.
212 It is a good idea to put all your wild-card and regex expressions inside
213 double quotes to prevent conf file scanning problems.
215 This is perhaps a bit overwhelming, so there are a number of examples included
216 below to illustrate how this works.
218 You find yourself using a lot of Regex statements, which will cost quite a lot
219 of CPU time, we recommend you simplify them if you can, or better yet
220 convert them to Wild statements which are much more efficient.
222 The directives within an Options resource may be one of the following:
226 \item [compression=GZIP]
227 \index[dir]{compression}
228 \index[dir]{Directive!compression}
229 All files saved will be software compressed using the GNU ZIP
230 compression format. The compression is done on a file by file basis by
231 the File daemon. If there is a problem reading the tape in a single
232 record of a file, it will at most affect that file and none of the other
233 files on the tape. Normally this option is {\bf not} needed if you have
234 a modern tape drive as the drive will do its own compression. In fact,
235 if you specify software compression at the same time you have hardware
236 compression turned on, your files may actually take more space on the
239 Software compression is very important if you are writing your Volumes
240 to a file, and it can also be helpful if you have a fast computer but a
241 slow network, otherwise it is generally better to rely your tape drive's
242 hardware compression. As noted above, it is not generally a good idea
243 to do both software and hardware compression.
245 Specifying {\bf GZIP} uses the default compression level 6 (i.e. {\bf
246 GZIP} is identical to {\bf GZIP6}). If you want a different compression
247 level (1 through 9), you can specify it by appending the level number
248 with no intervening spaces to {\bf GZIP}. Thus {\bf compression=GZIP1}
249 would give minimum compression but the fastest algorithm, and {\bf
250 compression=GZIP9} would give the highest level of compression, but
251 requires more computation. According to the GZIP documentation,
252 compression levels greater than six generally give very little extra
253 compression and are rather CPU intensive.
255 You can overwrite this option per Storage resource with
256 \ilink{AllowCompression}{AllowCompression} option.
258 \item [compression=LZO]
259 \index[dir]{compression}
260 \index[dir]{Directive!compression}
261 All files saved will be software compressed using the LZO
262 compression format. The compression is done on a file by file basis by
263 the File daemon. Everything else about GZIP is true for LZO.
265 LZO provides much faster compression and decompression speed but lower
266 compression ratio than GZIP. If your CPU is fast enough you should be able
267 to compress your data without making the backup duration longer.
269 Note that bacula only use one compression level LZO1X-1 specified by LZO.
271 You can overwrite this option per Storage resource with
272 \ilink{AllowCompression}{AllowCompression} option.
274 \item [signature=SHA1]
275 \index[dir]{signature}
277 \index[dir]{Directive!signature}
278 An SHA1 signature will be computed for all The SHA1 algorithm is
279 purported to be some what slower than the MD5 algorithm, but at the same
280 time is significantly better from a cryptographic point of view (i.e.
281 much fewer collisions, much lower probability of being hacked.) It adds
282 four more bytes than the MD5 signature. We strongly recommend that
283 either this option or MD5 be specified as a default for all files.
284 Note, only one of the two options MD5 or SHA1 can be computed for any
287 \item [signature=MD5]
288 \index[dir]{signature}
290 \index[dir]{Directive!signature}
291 An MD5 signature will be computed for all files saved. Adding this
292 option generates about 5\% extra overhead for each file saved. In
293 addition to the additional CPU time, the MD5 signature adds 16 more
294 bytes per file to your catalog. We strongly recommend that this option
295 or the SHA1 option be specified as a default for all files.
298 \item[basejob=\lt{}options\gt{}]
300 \index[dir]{Directive!basejob}
302 The options letters specified are used when running a {\bf Backup Level=Full}
303 with BaseJobs. The options letters are the same than in the \textbf{verify=}
306 \item[accurate=\lt{}options\gt{}] \index[dir]{accurate}
307 \index[dir]{Directive!accurate} The options letters specified are used when
308 running a {\bf Backup Level=Incremental/Differential} in Accurate mode. The
309 options letters are the same than in the \textbf{verify=} option below.
311 \item [verify=\lt{}options\gt{}]
313 \index[dir]{Directive!verify}
314 The options letters specified are used when running a {\bf Verify
315 Level=Catalog} as well as the {\bf DiskToCatalog} level job. The options
316 letters may be any combination of the following:
324 compare the permission bits
327 compare the number of links
339 compare the access time
342 compare the modification time (st\_mtime)
345 compare the change time (st\_ctime)
348 report file size decreases
351 compare the MD5 signature
354 compare the SHA1 signature
357 Only for Accurate option, it allows to always backup the file
361 A useful set of general options on the {\bf Level=Catalog} or {\bf
362 Level=DiskToCatalog} verify is {\bf pins5} i.e. compare permission bits,
363 inodes, number of links, size, and MD5 changes.
365 \item [onefs=yes\vb{}no]
367 \index[dir]{Directive!onefs}
368 If set to {\bf yes} (the default), {\bf Bacula} will remain on a single
369 file system. That is it will not backup file systems that are mounted
370 on a subdirectory. If you are using a *nix system, you may not even be
371 aware that there are several different filesystems as they are often
372 automatically mounted by the OS (e.g. /dev, /net, /sys, /proc, ...).
373 With Bacula 1.38.0 or later, it will inform you when it decides not to
374 traverse into another filesystem. This can be very useful if you forgot
375 to backup a particular partition. An example of the informational
376 message in the job report is:
380 rufus-fd: /misc is a different filesystem. Will not descend from / into /misc
381 rufus-fd: /net is a different filesystem. Will not descend from / into /net
382 rufus-fd: /var/lib/nfs/rpc_pipefs is a different filesystem. Will not descend from /var/lib/nfs into /var/lib/nfs/rpc_pipefs
383 rufus-fd: /selinux is a different filesystem. Will not descend from / into /selinux
384 rufus-fd: /sys is a different filesystem. Will not descend from / into /sys
385 rufus-fd: /dev is a different filesystem. Will not descend from / into /dev
386 rufus-fd: /home is a different filesystem. Will not descend from / into /home
390 Note: in previous versions of Bacula, the above message was of the form:
394 Filesystem change prohibited. Will not descend into /misc
398 If you wish to backup multiple filesystems, you can explicitly
399 list each filesystem you want saved. Otherwise, if you set the onefs option
400 to {\bf no}, Bacula will backup all mounted file systems (i.e. traverse mount
401 points) that are found within the {\bf FileSet}. Thus if you have NFS or
402 Samba file systems mounted on a directory listed in your FileSet, they will
403 also be backed up. Normally, it is preferable to set {\bf onefs=yes} and to
404 explicitly name each filesystem you want backed up. Explicitly naming the
405 filesystems you want backed up avoids the possibility of getting into a
406 infinite loop recursing filesystems. Another possibility is to
407 use {\bf onefs=no} and to set {\bf fstype=ext2, ...}.
408 See the example below for more details.
410 If you think that Bacula should be backing up a particular directory
411 and it is not, and you have {\bf onefs=no} set, before you complain,
421 where you replace {\bf filesystem} with the one in question. If the
422 {\bf Device:} number is different for / and for your filesystem, then they
423 are on different filesystems. E.g.
428 Size: 4096 Blocks: 16 IO Block: 4096 directory
429 Device: 302h/770d Inode: 2 Links: 26
430 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
431 Access: 2005-11-10 12:28:01.000000000 +0100
432 Modify: 2005-09-27 17:52:32.000000000 +0200
433 Change: 2005-09-27 17:52:32.000000000 +0200
437 Size: 4096 Blocks: 16 IO Block: 4096 directory
438 Device: 308h/776d Inode: 2 Links: 7
439 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
440 Access: 2005-11-10 12:28:02.000000000 +0100
441 Modify: 2005-11-06 12:36:48.000000000 +0100
442 Change: 2005-11-06 12:36:48.000000000 +0100
446 Also be aware that even if you include {\bf /home} in your list
447 of files to backup, as you most likely should, you will get the
448 informational message that "/home is a different filesystem" when
449 Bacula is processing the {\bf /} directory. This message does not
450 indicate an error. This message means that while examining the
451 {\bf File =} referred to in the second part of the message, Bacula will
452 not descend into the directory mentioned in the first part of the message.
453 However, it is possible that the separate filesystem will be backed up
454 despite the message. For example, consider the following FileSet:
463 where {\bf /var} is a separate filesystem. In this example, you will get a
464 message saying that Bacula will not decend from {\bf /} into {\bf /var}. But
465 it is important to realise that Bacula will descend into {\bf /var} from the
466 second File directive shown above. In effect, the warning is bogus,
467 but it is supplied to alert you to possible omissions from your FileSet. In
468 this example, {\bf /var} will be backed up. If you changed the FileSet such
469 that it did not specify {\bf /var}, then {\bf /var} will not be backed up.
472 \item [honor nodump flag=\lt{}yes\vb{}no\gt{}]
473 \index[dir]{honornodumpflag}
474 \index[dir]{Directive!honornodumpflag}
475 If your file system supports the {\bf nodump} flag (e. g. most
476 BSD-derived systems) Bacula will honor the setting of the flag
477 when this option is set to {\bf yes}. Files having this flag set
478 will not be included in the backup and will not show up in the
479 catalog. For directories with the {\bf nodump} flag set recursion
480 is turned off and the directory will be listed in the catalog.
481 If the {\bf honor nodump flag} option is not defined
482 or set to {\bf no} every file and directory will be eligible for
487 \item [portable=yes\vb{}no]
488 \index[dir]{portable}
489 \index[dir]{Directive!portable}
490 If set to {\bf yes} (default is {\bf no}), the Bacula File daemon will
491 backup Win32 files in a portable format, but not all Win32 file
492 attributes will be saved and restored. By default, this option is set
493 to {\bf no}, which means that on Win32 systems, the data will be backed
494 up using Windows API calls and on WinNT/2K/XP, all the security and
495 ownership attributes will be properly backed up (and restored). However
496 this format is not portable to other systems -- e.g. Unix, Win95/98/Me.
497 When backing up Unix systems, this option is ignored, and unless you
498 have a specific need to have portable backups, we recommend accept the
499 default ({\bf no}) so that the maximum information concerning your files
502 \item [recurse=yes\vb{}no]
504 \index[dir]{Directive!recurse}
505 If set to {\bf yes} (the default), Bacula will recurse (or descend) into
506 all subdirectories found unless the directory is explicitly excluded
507 using an {\bf exclude} definition. If you set {\bf recurse=no}, Bacula
508 will save the subdirectory entries, but not descend into the
509 subdirectories, and thus will not save the files or directories
510 contained in the subdirectories. Normally, you will want the default
513 \item [sparse=yes\vb{}no]
515 \index[dir]{Directive!sparse}
516 Enable special code that checks for sparse files such as created by
517 ndbm. The default is {\bf no}, so no checks are made for sparse files.
518 You may specify {\bf sparse=yes} even on files that are not sparse file.
519 No harm will be done, but there will be a small additional overhead to
520 check for buffers of all zero, and if there is a 32K block of all zeros
521 (see below), that block will become a hole in the file, which
522 may not be desirable if the original file was not a sparse file.
524 {\bf Restrictions:} Bacula reads files in 32K buffers. If the whole
525 buffer is zero, it will be treated as a sparse block and not written to
526 tape. However, if any part of the buffer is non-zero, the whole buffer
527 will be written to tape, possibly including some disk sectors (generally
528 4098 bytes) that are all zero. As a consequence, Bacula's detection of
529 sparse blocks is in 32K increments rather than the system block size.
530 If anyone considers this to be a real problem, please send in a request
531 for change with the reason.
533 If you are not familiar with sparse files, an example is say a file
534 where you wrote 512 bytes at address zero, then 512 bytes at address 1
535 million. The operating system will allocate only two blocks, and the
536 empty space or hole will have nothing allocated. However, when you read
537 the sparse file and read the addresses where nothing was written, the OS
538 will return all zeros as if the space were allocated, and if you backup
539 such a file, a lot of space will be used to write zeros to the volume.
540 Worse yet, when you restore the file, all the previously empty space
541 will now be allocated using much more disk space. By turning on the
542 {\bf sparse} option, Bacula will specifically look for empty space in
543 the file, and any empty space will not be written to the Volume, nor
544 will it be restored. The price to pay for this is that Bacula must
545 search each block it reads before writing it. On a slow system, this
546 may be important. If you suspect you have sparse files, you should
547 benchmark the difference or set sparse for only those files that are
550 You probably should not use this option on files or raw disk devices
551 that are not really sparse files (i.e. have holes in them).
554 \item [readfifo=yes\vb{}no]
555 \index[dir]{readfifo}
556 \index[dir]{Directive!readfifo}
557 If enabled, tells the Client to read the data on a backup and write the
558 data on a restore to any FIFO (pipe) that is explicitly mentioned in the
559 FileSet. In this case, you must have a program already running that
560 writes into the FIFO for a backup or reads from the FIFO on a restore.
561 This can be accomplished with the {\bf RunBeforeJob} directive. If this
562 is not the case, Bacula will hang indefinitely on reading/writing the
563 FIFO. When this is not enabled (default), the Client simply saves the
564 directory entry for the FIFO.
566 Unfortunately, when Bacula runs a RunBeforeJob, it waits until that
567 script terminates, and if the script accesses the FIFO to write
568 into the it, the Bacula job will block and everything will stall.
569 However, Vladimir Stavrinov as supplied tip that allows this feature
570 to work correctly. He simply adds the following to the beginning
571 of the RunBeforeJob script:
577 \item [noatime=yes\vb{}no]
579 \index[dir]{Directive!noatime}
580 If enabled, and if your Operating System supports the O\_NOATIME file
581 open flag, Bacula will open all files to be backed up with this option.
582 It makes it possible to read a file without updating the inode atime
583 (and also without the inode ctime update which happens if you try to set
584 the atime back to its previous value). It also prevents a race
585 condition when two programs are reading the same file, but only one does
586 not want to change the atime. It's most useful for backup programs and
587 file integrity checkers (and bacula can fit on both categories).
589 This option is particularly useful for sites where users are sensitive
590 to their MailBox file access time. It replaces both the {\bf keepatime}
591 option without the inconveniences of that option (see below).
593 If your Operating System does not support this option, it will be
594 silently ignored by Bacula.
597 \item [mtimeonly=yes\vb{}no]
598 \index[dir]{mtimeonly}
599 \index[dir]{Directive!mtimeonly}
600 If enabled, tells the Client that the selection of files during
601 Incremental and Differential backups should based only on the st\_mtime
602 value in the stat() packet. The default is {\bf no} which means that
603 the selection of files to be backed up will be based on both the
604 st\_mtime and the st\_ctime values. In general, it is not recommended
607 \item [keepatime=yes\vb{}no]
608 \index[dir]{keepatime}
609 \index[dir]{Directive!keepatime}
610 The default is {\bf no}. When enabled, Bacula will reset the st\_atime
611 (access time) field of files that it backs up to their value prior to
612 the backup. This option is not generally recommended as there are very
613 few programs that use st\_atime, and the backup overhead is increased
614 because of the additional system call necessary to reset the times.
615 However, for some files, such as mailboxes, when Bacula backs up the
616 file, the user will notice that someone (Bacula) has accessed the
617 file. In this, case keepatime can be useful.
618 (I'm not sure this works on Win32).
620 Note, if you use this feature, when Bacula resets the access time, the
621 change time (st\_ctime) will automatically be modified by the system,
622 so on the next incremental job, the file will be backed up even if
623 it has not changed. As a consequence, you will probably also want
624 to use {\bf mtimeonly = yes} as well as keepatime (thanks to
625 Rudolf Cejka for this tip).
627 \item [checkfilechanges=yes\vb{}no]
628 \index[dir]{checkfilechanges}
629 \index[dir]{Directive!checkfilechanges}
630 On versions 2.0.4 or greater,
631 if enabled, the Client will check size, age of each file after
632 their backup to see if they have changed during backup. If time
633 or size mismatch, an error will raise.
636 zog-fd: Client1.2007-03-31_09.46.21 Error: /tmp/test mtime changed during backup.
639 In general, it is recommended to use this option.
641 \item [hardlinks=yes\vb{}no]
642 \index[dir]{hardlinks}
643 \index[dir]{Directive!hardlinks}
644 When enabled (default), this directive will cause hard links to be
645 backed up. However, the File daemon keeps track of hard linked files and
646 will backup the data only once. The process of keeping track of the
647 hard links can be quite expensive if you have lots of them (tens of
648 thousands or more). This doesn't occur on normal Unix systems, but if
649 you use a program like BackupPC, it can create hundreds of thousands, or
650 even millions of hard links. Backups become very long and the File daemon
651 will consume a lot of CPU power checking hard links. In such a case,
652 set {\bf hardlinks=no} and hard links will not be backed up. Note, using
653 this option will most likely backup more data and on a restore the file
654 system will not be restored identically to the original.
656 \item [wild=\lt{}string\gt{}]
658 \index[dir]{Directive!wild}
659 Specifies a wild-card string to be applied to the filenames and
660 directory names. Note, if {\bf Exclude} is not enabled, the wild-card
661 will select which files are to be included. If {\bf Exclude=yes} is
662 specified, the wild-card will select which files are to be excluded.
663 Multiple wild-card directives may be specified, and they will be applied
664 in turn until the first one that matches. Note, if you exclude a
665 directory, no files or directories below it will be matched.
667 You may want to test your expressions prior to running your
668 backup by using the bwild program. Please see the
669 \ilink{Utilities}{bwild} chapter of this manual for
670 more. You can also test your full FileSet definition by using
671 the \ilink{estimate}{estimate} command in the Console
672 chapter of this manual.
673 It is recommended to enclose the string in double quotes.
675 \item [wilddir=\lt{}string\gt{}]
677 \index[dir]{Directive!wilddir}
678 Specifies a wild-card string to be applied to directory names only. No
679 filenames will be matched by this directive. Note, if {\bf Exclude} is
680 not enabled, the wild-card will select directories to be
681 included. If {\bf Exclude=yes} is specified, the wild-card will select
682 which directories are to be excluded. Multiple wild-card directives may be
683 specified, and they will be applied in turn until the first one that
684 matches. Note, if you exclude a directory, no files or directories
685 below it will be matched.
687 It is recommended to enclose the string in double quotes.
689 You may want to test your expressions prior to running your
690 backup by using the bwild program. Please see the
691 \ilink{Utilities}{bwild} chapter of this manual for
692 more. You can also test your full FileSet definition by using
693 the \ilink{estimate}{estimate} command in the Console
694 chapter of this manual.
695 An example of excluding with the WildDir option on Win32 machines is
698 \item [wildfile=\lt{}string\gt{}]
699 \index[dir]{wildfile}
700 \index[dir]{Directive!wildfile}
701 Specifies a wild-card string to be applied to non-directories. That
702 is no directory entries will be matched by this directive.
703 However, note that the match is done against the full path and filename,
704 so your wild-card string must take into account that filenames
705 are preceded by the full path.
707 is not enabled, the wild-card will select which files are to be
708 included. If {\bf Exclude=yes} is specified, the wild-card will select
709 which files are to be excluded. Multiple wild-card directives may be
710 specified, and they will be applied in turn until the first one that
713 It is recommended to enclose the string in double quotes.
715 You may want to test your expressions prior to running your
716 backup by using the bwild program. Please see the
717 \ilink{Utilities}{bwild} chapter of this manual for
718 more. You can also test your full FileSet definition by using
719 the \ilink{estimate}{estimate} command in the Console
720 chapter of this manual.
721 An example of excluding with the WildFile option on Win32 machines is
725 \item [regex=\lt{}string\gt{}]
727 \index[dir]{Directive!regex}
728 Specifies a POSIX extended regular expression to be applied to the
729 filenames and directory names, which include the full path. If {\bf
730 Exclude} is not enabled, the regex will select which files are to be
731 included. If {\bf Exclude=yes} is specified, the regex will select
732 which files are to be excluded. Multiple regex directives may be
733 specified within an Options resource, and they will be applied in turn
734 until the first one that matches. Note, if you exclude a directory, no
735 files or directories below it will be matched.
737 It is recommended to enclose the string in double quotes.
739 The regex libraries differ from one operating system to
740 another, and in addition, regular expressions are complicated,
741 so you may want to test your expressions prior to running your
742 backup by using the bregex program. Please see the
743 \ilink{Utilities}{bwild} chapter of this manual for
744 more. You can also test your full FileSet definition by using
745 the \ilink{estimate}{estimate} command in the Console
746 chapter of this manual.
748 You find yourself using a lot of Regex statements, which will cost quite a lot
749 of CPU time, we recommend you simplify them if you can, or better yet
750 convert them to Wild statements which are much more efficient.
753 \item [regexfile=\lt{}string\gt{}]
754 \index[dir]{regexfile}
755 \index[dir]{Directive!regexfile}
756 Specifies a POSIX extended regular expression to be applied to
757 non-directories. No directories will be matched by this directive.
758 However, note that the match is done against the full path and
759 filename, so your regex string must take into account that filenames
760 are preceded by the full path.
761 If {\bf Exclude} is not enabled, the regex will select which files are
762 to be included. If {\bf Exclude=yes} is specified, the regex will
763 select which files are to be excluded. Multiple regex directives may be
764 specified, and they will be applied in turn until the first one that
767 It is recommended to enclose the string in double quotes.
769 The regex libraries differ from one operating system to
770 another, and in addition, regular expressions are complicated,

772 backup by using the bregex program. Please see the
773 \ilink{Utilities}{bregex} chapter of this manual for
777 \item [regexdir=\lt{}string\gt{}]
778 \index[dir]{regexdir}
779 \index[dir]{Directive!regexdir}
780 Specifies a POSIX extended regular expression to be applied to directory
781 names only. No filenames will be matched by this directive. Note, if
782 {\bf Exclude} is not enabled, the regex will select directories
783 files are to be included. If {\bf Exclude=yes} is specified, the
784 regex will select which files are to be excluded. Multiple
785 regex directives may be specified, and they will be applied in turn
786 until the first one that matches. Note, if you exclude a directory, no
787 files or directories below it will be matched.

795 \ilink{Utilities}{bregex} chapter of this manual for
799 \item [exclude=yes\vb{}no]
801 \index[dir]{Directive!exclude}
802 The default is {\bf no}. When enabled, any files matched within the
803 Options will be excluded from the backup.
806 \item [aclsupport=yes\vb{}no]
807 \index[dir]{aclsupport}
808 \index[dir]{Directive!aclsupport}
809 The default is {\bf no}. If this option is set to yes, and you have the
810 POSIX {\bf libacl} installed on your Linux system, Bacula will backup the
811 file and directory Unix Access Control Lists (ACL) as defined in IEEE Std
812 1003.1e draft 17 and "POSIX.1e" (abandoned). This feature is
813 available on Unix systems only and requires the Linux ACL library. Bacula is
814 automatically compiled with ACL support if the {\bf libacl} library is
815 installed on your Linux system (shown in config.out). While restoring the
816 files Bacula will try to restore the ACLs, if there is no ACL support
817 available on the system, Bacula restores the files and directories but
818 not the ACL information. Please note, if you backup an EXT3 or XFS
819 filesystem with ACLs, then you restore them to a different filesystem
820 (perhaps reiserfs) that does not have ACLs, the ACLs will be ignored.
822 For other operating systems there is support for either POSIX ACLs or
823 the more extensible NFSv4 ACLs.
825 The ACL stream format between Operation Systems is \textbf{not}
826 compatible so for example an ACL saved on Linux cannot be restored on
829 The following Operating Systems are currently supported:
832 \item AIX (pre-5.3 (POSIX) and post 5.3 (POSIX and NFSv4) ACLs)
834 \item FreeBSD (POSIX and NFSv4/ZFS ACLs)
838 \item Solaris (POSIX and NFSv4/ZFS ACLs)
843 \item [xattrsupport=yes\vb{}no]
844 \index[dir]{xattrsupport}
845 \index[dir]{Directive!xattrsupport}
846 The default is {\bf no}. If this option is set to yes, and your
847 operating system support either so called Extended Attributes or
848 Extensible Attributes Bacula will backup the file and directory
849 XATTR data. This feature is available on UNIX only and depends on
850 support of some specific library calls in libc.
852 The XATTR stream format between Operating Systems is {\bf not}
853 compatible so an XATTR saved on Linux cannot for example be restored
856 On some operating systems ACLs are also stored as Extended Attributes
857 (Linux, Darwin, FreeBSD) Bacula checks if you have the aclsupport
858 option enabled and if so will not save the same info when saving
859 extended attribute information. Thus ACLs are only saved once.
861 The following Operating Systems are currently supported:
864 \item AIX (Extended Attributes)
865 \item Darwin (Extended Attributes)
866 \item FreeBSD (Extended Attributes)
867 \item IRIX (Extended Attributes)
868 \item Linux (Extended Attributes)
869 \item NetBSD (Extended Attributes)
870 \item Solaris (Extended Attributes and Extensible Attributes)
871 \item Tru64 (Extended Attributes)
874 \item [ignore case=yes\vb{}no]
875 \index[dir]{ignore case}
876 \index[dir]{Directive!ignore case}
877 The default is {\bf no}. On Windows systems, you will almost surely
878 want to set this to {\bf yes}. When this directive is set to {\bf yes}
879 all the case of character will be ignored in wild-card and regex
880 comparisons. That is an uppercase A will match a lowercase a.
882 \item [fstype=filesystem-type]
884 \index[dir]{Directive!fstype}
885 This option allows you to select files and directories by the
886 filesystem type. The permitted filesystem-type names are:
888 ext2, jfs, ntfs, proc, reiserfs, xfs, usbdevfs, sysfs, smbfs,
891 You may have multiple Fstype directives, and thus permit matching
892 of multiple filesystem types within a single Options resource. If
893 the type specified on the fstype directive does not match the
894 filesystem for a particular directive, that directory will not be
895 backed up. This directive can be used to prevent backing up
896 non-local filesystems. Normally, when you use this directive, you
897 would also set {\bf onefs=no} so that Bacula will traverse filesystems.
899 This option is not implemented in Win32 systems.
901 \item [DriveType=Windows-drive-type]
902 \index[dir]{DriveType}
903 \index[dir]{Directive!DriveType}
904 This option is effective only on Windows machines and is
905 somewhat similar to the Unix/Linux {\bf fstype} described
906 above, except that it allows you to select what Windows
907 drive types you want to allow. By default all drive
910 The permitted drivetype names are:
912 removable, fixed, remote, cdrom, ramdisk
914 You may have multiple Driveype directives, and thus permit matching
915 of multiple drive types within a single Options resource. If
916 the type specified on the drivetype directive does not match the
917 filesystem for a particular directive, that directory will not be
918 backed up. This directive can be used to prevent backing up
919 non-local filesystems. Normally, when you use this directive, you
920 would also set {\bf onefs=no} so that Bacula will traverse filesystems.
922 This option is not implemented in Unix/Linux systems.
925 \item [hfsplussupport=yes\vb{}no]
926 \index[dir]{hfsplussupport}
927 \index[dir]{Directive!hfsplussupport}
928 This option allows you to turn on support for Mac OSX HFS plus
931 \item [strippath=\lt{}integer\gt{}]
932 \index[dir]{strippath}
933 \index[dir]{Directive!strippath}
934 This option will cause {\bf integer} paths to be stripped from
935 the front of the full path/filename being backed up. This can
936 be useful if you are migrating data from another vendor or if
937 you have taken a snapshot into some subdirectory. This directive
938 can cause your filenames to be overlayed with regular backup data,
939 so should be used only by experts and with great care.
942 {\bf \lt{}file-list\gt{}} is a list of directory and/or filename names
943 specified with a {\bf File =} directive. To include names containing spaces,
944 enclose the name between double-quotes. Wild-cards are not interpreted
945 in file-lists. They can only be specified in Options resources.
947 There are a number of special cases when specifying directories and files in a
948 {\bf file-list}. They are:
951 \item Any name preceded by an at-sign (@) is assumed to be the name of a
952 file, which contains a list of files each preceded by a "File =". The
953 named file is read once when the configuration file is parsed during the
954 Director startup. Note, that the file is read on the Director's machine
955 and not on the Client's. In fact, the @filename can appear anywhere
956 within the conf file where a token would be read, and the contents of
957 the named file will be logically inserted in the place of the @filename.
958 What must be in the file depends on the location the @filename is
959 specified in the conf file. For example:
964 Options { compression=GZIP }
965 @/home/files/my-files
970 \item Any name beginning with a vertical bar (\vb) is assumed to be the name of
971 a program. This program will be executed on the Director's machine at
972 the time the Job starts (not when the Director reads the configuration
973 file), and any output from that program will be assumed to be a list of
974 files or directories, one per line, to be included. Before submitting the
975 specified command bacula will performe
976 \ilink{character substitution}{character substitution}.
978 This allows you to have a job that, for example, includes all the local
979 partitions even if you change the partitioning by adding a disk. The
980 examples below show you how to do this. However, please note two
982 1. if you want the local filesystems, you probably should be
983 using the new {\bf fstype} directive, which was added in version 1.36.3
984 and set {\bf onefs=no}.
987 2. the exact syntax of the command needed in the examples below is very
988 system dependent. For example, on recent Linux systems, you may need to
989 add the -P option, on FreeBSD systems, the options will be different as
992 In general, you will need to prefix your command or commands with a {\bf
993 sh -c} so that they are invoked by a shell. This will not be the case
994 if you are invoking a script as in the second example below. Also, you
995 must take care to escape (precede with a \textbackslash{}) wild-cards,
996 shell character, and to ensure that any spaces in your command are
997 escaped as well. If you use a single quotes (') within a double quote
998 ("), Bacula will treat everything between the single quotes as one field
999 so it will not be necessary to escape the spaces. In general, getting
1000 all the quotes and escapes correct is a real pain as you can see by the
1001 next example. As a consequence, it is often easier to put everything in
1002 a file and simply use the file name within Bacula. In that case the
1003 {\bf sh -c} will not be necessary providing the first line of the file
1004 is {\bf \#!/bin/sh}.
1012 Options { signature = SHA1 }
1013 File = "|sh -c 'df -l | grep \"^/dev/hd[ab]\" | grep -v \".*/tmp\" \
1014 | awk \"{print \\$6}\"'"
1019 will produce a list of all the local partitions on a Red Hat Linux system.
1020 Note, the above line was split, but should normally be written on one line.
1021 Quoting is a real problem because you must quote for Bacula which consists of
1022 preceding every \textbackslash{} and every " with a \textbackslash{}, and
1023 you must also quote for the shell command. In the end, it is probably easier
1024 just to execute a small file with:
1033 File = "|my_partitions"
1038 where my\_partitions has:
1043 df -l | grep "^/dev/hd[ab]" | grep -v ".*/tmp" \
1048 If the vertical bar (\verb+|+) in front of my\_partitions is preceded by a
1049 backslash as in \textbackslash{}\verb+|+, the program will be executed on the
1050 Client's machine instead of on the Director's machine.
1051 Please note that if the filename is given within quotes, you
1052 will need to use two slashes. An example, provided by John Donagher,
1053 that backs up all the local UFS partitions on a remote system is:
1058 Name = "All local partitions"
1060 Options { signature=SHA1; onefs=yes; }
1061 File = "\\|bash -c \"df -klF ufs | tail +2 | awk '{print \$6}'\""
1067 The above requires two backslash characters after the double quote (one
1068 preserves the next one). If you are a Linux user, just change the {\bf ufs}
1069 to {\bf ext3} (or your preferred filesystem type), and you will be in
1072 If you know what filesystems you have mounted on your system, e.g.
1073 for Red Hat Linux normally only ext2 and ext3, you can backup
1074 all local filesystems using something like:
1080 Options { signature = SHA1; onfs=no; fstype=ext2 }
1087 \item Any file-list item preceded by a less-than sign (\lt{}) will be taken
1088 to be a file. This file will be read on the Director's machine (see
1089 below for doing it on the Client machine) at the time
1090 the Job starts, and the data will be assumed to be a list of directories or
1091 files, one per line, to be included. The names should start in column 1 and
1092 should not be quoted even if they contain spaces. This feature allows you to
1093 modify the external file and change what will be saved without stopping and
1094 restarting Bacula as would be necessary if using the @ modifier noted above.
1100 Options { signature = SHA1 }
1101 File = "</home/files/local-filelist"
1106 If you precede the less-than sign (\lt{}) with a backslash as in
1107 \textbackslash{}\lt{}, the file-list will be read on the Client machine
1108 instead of on the Director's machine. Please note that if the filename
1109 is given within quotes, you will need to use two slashes.
1114 Options { signature = SHA1 }
1115 File = "\\</home/xxx/filelist-on-client"
1120 \item If you explicitly specify a block device such as {\bf /dev/hda1}, then
1121 Bacula (starting with version 1.28) will assume that this is a raw partition
1122 to be backed up. In this case, you are strongly urged to specify a {\bf
1123 sparse=yes} include option, otherwise, you will save the whole partition
1124 rather than just the actual data that the partition contains. For example:
1129 Options { signature=MD5; sparse=yes }
1135 will backup the data in device /dev/hd6. Note, the {bf /dev/hd6} must be
1136 the raw partition itself. Bacula will not back it up as a raw device if
1137 you specify a symbolic link to a raw device such as my be created by the
1138 LVM Snapshot utilities.
1140 Ludovic Strappazon has pointed out that this feature can be used to backup a
1141 full Microsoft Windows disk. Simply boot into the system using a Linux Rescue
1142 disk, then load a statically linked Bacula as described in the
1143 \ilink{ Disaster Recovery Using Bacula}{RescueChapter} chapter of
1144 this manual. Then save the whole disk partition. In the case of a disaster,
1145 you can then restore the desired partition by again booting with the rescue
1146 disk and doing a restore of the partition.
1147 \item If you explicitly specify a FIFO device name (created with mkfifo), and
1148 you add the option {\bf readfifo=yes} as an option, Bacula will read the FIFO
1149 and back its data up to the Volume. For example:
1158 File = /home/abc/fifo
1163 if {\bf /home/abc/fifo} is a fifo device, Bacula will open the fifo,
1164 read it, and store all data thus obtained on the Volume. Please note,
1165 you must have a process on the system that is writing into the fifo, or
1166 Bacula will hang, and after one minute of waiting, Bacula will give up
1167 and go on to the next file. The data read can be anything since Bacula
1168 treats it as a stream.
1170 This feature can be an excellent way to do a "hot" backup of a very
1171 large database. You can use the {\bf RunBeforeJob} to create the fifo
1172 and to start a program that dynamically reads your database and writes
1173 it to the fifo. Bacula will then write it to the Volume. Be sure to
1174 read the \ilink{readfifo section}{readfifo} that gives a
1175 tip to ensure that the RunBeforeJob does not block Bacula.
1177 During the restore operation, the inverse is true, after Bacula creates
1178 the fifo if there was any data stored with it (no need to explicitly
1179 list it or add any options), that data will be written back to the fifo.
1180 As a consequence, if any such FIFOs exist in the fileset to be restored,
1181 you must ensure that there is a reader program or Bacula will block, and
1182 after one minute, Bacula will time out the write to the fifo and move on
1185 \item A file-list may not contain wild-cards. Use directives in the
1186 Options resource if you wish to specify wild-cards or regular expression
1190 \index[general]{IgnoreDir}
1191 The {\bf ExcludeDirContaining = \lt{}filename\gt{}} is a directive that
1192 can be added to the Include section of the FileSet resource. If the specified
1193 filename ({\bf filename-string}) is found on the Client in any directory to be
1194 backed up, the whole directory will be ignored (not backed up). For example:
1197 # List of files to be backed up
1205 Exclude Dir Containing = .excludeme
1210 But in /home, there may be hundreds of directories of users and some
1211 people want to indicate that they don't want to have certain
1212 directories backed up. For example, with the above FileSet, if
1213 the user or sysadmin creates a file named {\bf .excludeme} in
1214 specific directories, such as
1217 /home/user/www/cache/.excludeme
1218 /home/user/temp/.excludeme
1221 then Bacula will not backup the two directories named:
1224 /home/user/www/cache
1228 NOTE: subdirectories will not be backed up. That is, the directive
1229 applies to the two directories in question and any children (be they
1230 files, directories, etc).
1234 \section{FileSet Examples}
1235 \index[general]{Examples!FileSet }
1236 \index[general]{FileSet Examples}
1238 The following is an example of a valid FileSet resource definition. Note,
1239 the first Include pulls in the contents of the file {\bf /etc/backup.list}
1240 when Bacula is started (i.e. the @), and that file must have each filename
1241 to be backed up preceded by a {\bf File =} and on a separate line.
1262 File = /usr/lib/another_file
1268 In the above example, all the files contained in /etc/backup.list will
1269 be compressed with GZIP compression, an SHA1 signature will be computed on the
1270 file's contents (its data), and sparse file handling will apply.
1272 The two directories /root/myfile and /usr/lib/another\_file will also be saved
1273 without any options, but all files in those directories with the extensions
1274 {\bf .o} and {\bf .exe} will be excluded.
1276 Let's say that you now want to exclude the directory /tmp. The simplest way
1277 to do so is to add an exclude directive that lists /tmp. The example
1278 above would then become:
1299 File = /usr/lib/another_file
1302 File = /tmp # don't add trailing /
1309 You can add wild-cards to the File directives listed in the Exclude
1310 directory, but you need to take care because if you exclude a directory,
1311 it and all files and directories below it will also be excluded.
1313 Now lets take a slight variation on the above and suppose
1314 you want to save all your whole filesystem except {\bf /tmp}.
1315 The problem that comes up is that Bacula will not normally
1316 cross from one filesystem to another.
1317 Doing a {\bf df} command, you get the following output:
1322 Filesystem 1k-blocks Used Available Use% Mounted on
1323 /dev/hda5 5044156 439232 4348692 10% /

1339 deuter:/files 44133352 27652876 14238608 67% /mnt/deuter/files
1343 And we see that there are a number of separate filesystems (/ /boot
1344 /home /rescue /tmp and /usr not to mention mounted systems).
1345 If you specify only {\bf /} in your Include list, Bacula will only save the
1346 Filesystem {\bf /dev/hda5}. To save all filesystems except {\bf /tmp} with
1347 out including any of the Samba or NFS mounted systems, and explicitly
1348 excluding a /tmp, /proc, .journal, and .autofsck, which you will not want to
1349 be saved and restored, you can use the following:
1354 Name = Include_example
1359 wildfile = "/.journal"
1360 wildfile = "/.autofsck"
1373 Since /tmp is on its own filesystem and it was not explicitly named in the
1374 Include list, it is not really needed in the exclude list. It is better to
1375 list it in the Exclude list for clarity, and in case the disks are changed so
1376 that it is no longer in its own partition.
1378 Now, lets assume you only want to backup .Z and .gz files and nothing
1379 else. This is a bit trickier because Bacula by default will select
1380 everything to backup, so we must exclude everything but .Z and .gz files.
1381 If we take the first example above and make the obvious modifications
1382 to it, we might come up with a FileSet that looks like this:
1388 Include { !!!!!!!!!!!!
1390 wildfile = "*.Z" example
1391 wildfile = "*.gz" doesn't
1400 The *.Z and *.gz files will indeed be backed up, but all other files
1401 that are not matched by the Options directives will automatically
1402 be backed up too (i.e. that is the default rule).
1404 To accomplish what we want, we must explicitly exclude all other files.
1405 We do this with the following:
1426 The "trick" here was to add a RegexFile expression that matches
1427 all files. It does not match directory names, so all directories in
1428 /myfile will be backed up (the directory entry) and any *.Z and *.gz
1429 files contained in them. If you know that certain directories do
1430 not contain any *.Z or *.gz files and you do not want the directory
1431 entries backed up, you will need to explicitly exclude those directories.
1432 Backing up a directory entries is not very expensive.
1434 Bacula uses the system regex library and some of them are
1435 different on different OSes. The above has been reported not to work
1436 on FreeBSD. This can be tested by using the {\bf estimate job=job-name
1437 listing} command in the console and adapting the RegexFile expression
1438 appropriately. In a future version of Bacula, we will supply our own
1439 Regex code to avoid such system dependencies.
1441 Please be aware that allowing Bacula to traverse or change file systems can be
1442 {\bf very} dangerous. For example, with the following:
1447 Name = "Bad example"
1449 Options { onefs=no }
1456 you will be backing up an NFS mounted partition ({\bf /mnt/matou}), and since
1457 {\bf onefs} is set to {\bf no}, Bacula will traverse file systems. Now if {\bf
1458 /mnt/matou} has the current machine's file systems mounted, as is often the
1459 case, you will get yourself into a recursive loop and the backup will never
1462 As a final example, let's say that you have only one or two
1463 subdirectories of /home that you want to backup. For example,
1464 you want to backup only subdirectories beginning with the letter
1465 a and the letter b -- i.e. /home/a* and /home/b*. Now, you might first
1473 wilddir = "/home/a*"
1474 wilddir = "/home/b*"
1482 The problem is that the above will include everything in /home. To get
1483 things to work correctly, you need to start with the idea of exclusion
1484 instead of inclusion. So, you could simply exclude all directories
1485 except the two you want to use:
1492 RegexDir = "^/home/[c-z]"
1501 And assuming that all subdirectories start with a lowercase letter, this
1504 An alternative would be to include the two subdirectories desired and
1505 exclude everything else:
1512 wilddir = "/home/a*"
1513 wilddir = "/home/b*"
1526 The following example shows how to back up only the My Pictures directory inside
1527 the My Documents directory for all users in C:/Documents and Settings, i.e.
1528 everything matching the pattern:
1530 C:/Documents and Settings/*/My Documents/My Pictures/*
1532 To understand how this can be achieved, there are two important points to
1535 Firstly, Bacula walks over the filesystem depth-first starting from the File =
1536 lines. It stops descending when a directory is excluded, so you must include
1537 all ancestor directories of each directory containing files to be included.
1539 Secondly, each directory and file is compared to the Options clauses in the
1540 order they appear in the FileSet. When a match is found, no further clauses
1541 are compared and the directory or file is either included or excluded.
1543 The FileSet resource definition below implements this by including specifc
1544 directories and files and excluding everything else.
1549 Name = "AllPictures"
1553 File = "C:/Documents and Settings"
1560 # Include all users' directories so we reach the inner ones. Unlike a
1561 # WildDir pattern ending in *, this RegExDir only matches the top-level
1562 # directories and not any inner ones.
1563 RegExDir = "^C:/Documents and Settings/[^/]+$"
1565 # Ditto all users' My Documents directories.
1566 WildDir = "C:/Documents and Settings/*/My Documents"
1568 # Ditto all users' My Documents/My Pictures directories.
1569 WildDir = "C:/Documents and Settings/*/My Documents/My Pictures"
1571 # Include the contents of the My Documents/My Pictures directories and
1572 # any subdirectories.
1573 Wild = "C:/Documents and Settings/*/My Documents/My Pictures/*"
1580 # Exclude everything else, in particular any files at the top level and
1581 # any other directories or files in the users' directories.
1582 Wild = "C:/Documents and Settings/*"

1591 \index[general]{Backing up Raw Partitions }
1593 The following FileSet definition will backup a raw partition:
1598 Name = "RawPartition"
1600 Options { sparse=yes }
1607 While backing up and restoring a raw partition, you should ensure that no
1608 other process including the system is writing to that partition. As a
1609 precaution, you are strongly urged to ensure that the raw partition is not
1610 mounted or is mounted read-only. If necessary, this can be done using the {\bf
1611 RunBeforeJob} directive.

1618 You may also include full filenames or directory names in addition to using
1619 wild-cards and {\bf Exclude=yes} in the Options resource as specified above by
1620 simply including the files to be excluded in an Exclude resource within the

1651 \index[general]{FileSets!Windows }
1652 If you are entering Windows file names, the directory path may be preceded by
1653 the drive and a colon (as in c:). However, the path separators must be
1654 specified in Unix convention (i.e. forward slash (/)). If you wish to include
1655 a quote in a file name, precede the quote with a backslash
1656 (\textbackslash{}). For example you might use the following
1657 for a Windows machine to backup the "My Documents" directory:
1662 Name = "Windows Set"
1669 File = "c:/My Documents"
1675 For exclude lists to work correctly on Windows, you must observe the following
1679 \item Filenames are case sensitive, so you must use the correct case.
1680 \item To exclude a directory, you must not have a trailing slash on the
1682 \item If you have spaces in your filename, you must enclose the entire name
1683 in double-quote characters ("). Trying to use a backslash before the space
1685 \item If you are using the old Exclude syntax (noted below), you may not
1686 specify a drive letter in the exclude. The new syntax noted above
1687 should work fine including driver letters.
1690 Thanks to Thiago Lima for summarizing the above items for us. If you are
1691 having difficulties getting includes or excludes to work, you might want to
1692 try using the {\bf estimate job=xxx listing} command documented in the
1693 \ilink{Console chapter}{estimate} of this manual.
1695 On Win32 systems, if you move a directory or file or rename a file into the
1696 set of files being backed up, and a Full backup has already been made, Bacula
1697 will not know there are new files to be saved during an Incremental or
1698 Differential backup (blame Microsoft, not me). To avoid this problem, please
1699 {\bf copy} any new directory or files into the backup area. If you do not have
1700 enough disk to copy the directory or files, move them, but then initiate a

1845 You could then add some test files to the directory {\bf /home/xxx/test}
1846 and use the following command in the console:
