7 \index[general]{Configuration!Storage Daemon}
9 The Storage Daemon configuration file has relatively few resource definitions.
10 However, due to the great variation in backup media and system capabilities,
11 the storage daemon must be highly configurable. As a consequence, there are
12 quite a large number of directives in the Device Resource definition that
13 allow you to define all the characteristics of your Storage device (normally a
14 tape drive). Fortunately, with modern storage devices, the defaults are
15 sufficient, and very few directives are actually needed.
17 Examples of {\bf Device} resource directives that are known to work for a
18 number of common tape drives can be found in the {\bf
19 \lt{}bacula-src\gt{}/examples/devices} directory, and most will also be listed
22 For a general discussion of configuration file and resources including the
23 data types recognized by {\bf Bacula}, please see the
24 \ilink{Configuration}{ConfigureChapter} chapter of this manual. The
25 following Storage Resource definitions must be defined:
29 \ilink{Storage}{StorageResource} -- to define the name of the
32 \ilink{Director}{DirectorResource1} -- to define the Director's
33 name and his access password.
35 \ilink{Device}{DeviceResource} -- to define the
36 characteristics of your storage device (tape drive).
38 \ilink{Messages}{MessagesChapter} -- to define where error and
39 information messages are to be sent.
42 \section{Storage Resource}
43 \label{StorageResource}
44 \index[general]{Resource!Storage}
45 \index[general]{Storage Resource}
47 In general, the properties specified under the Storage resource define global
48 properties of the Storage daemon. Each Storage daemon configuration file must
49 have one and only one Storage resource definition.
53 \item [Name = \lt{}Storage-Daemon-Name\gt{}]
55 \index[sd]{Directive!Name}
56 Specifies the Name of the Storage daemon. This directive is required.
58 \item [Working Directory = \lt{}Directory\gt{}]
59 \index[sd]{Working Directory}
60 \index[sd]{Directive!Working Directory}
61 This directive is mandatory and specifies a directory in which the Storage
62 daemon may put its status files. This directory should be used only by {\bf
63 Bacula}, but may be shared by other Bacula daemons provided the names
64 given to each daemon are unique. This directive is
67 \item [Pid Directory = \lt{}Directory\gt{}]
68 \index[sd]{Pid Directory}
69 \index[sd]{Directive!Pid Directory}
70 This directive is mandatory and specifies a directory in which the Director
71 may put its process Id file files. The process Id file is used to shutdown
72 Bacula and to prevent multiple copies of Bacula from running simultaneously.
73 This directive is required. Standard shell expansion of the {\bf Directory}
74 is done when the configuration file is read so that values such as {\bf
75 \$HOME} will be properly expanded.
77 Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
78 not installing Bacula in the system directories, you can use the {\bf Working
79 Directory} as defined above.
81 \item [Heartbeat Interval = \lt{}time-interval\gt{}]
82 \index[sd]{Heartbeat Interval}
83 \index[sd]{Directive!Heartbeat Interval}
84 \index[general]{Heartbeat Interval}
85 \index[general]{Broken pipe}
86 This directive defines an interval of time in seconds. When
87 the Storage daemon is waiting for the operator to mount a
88 tape, each time interval, it will send a heartbeat signal to
89 the File daemon. The default interval is zero which disables
90 the heartbeat. This feature is particularly useful if you
91 have a router such as 3Com that does not follow Internet
92 standards and times out an valid connection after a short
93 duration despite the fact that keepalive is set. This usually
94 results in a broken pipe error message.
96 \item [Client Connect Wait = \lt{}time-interval\gt{}]
97 \index[sd]{Connect Wait}
98 \index[sd]{Directive!Connect Wait}
99 \index[general]{Client Connect Wait}
100 This directive defines an interval of time in seconds that
101 the Storage daemon will wait for a Client (the File daemon)
102 to connect. The default is 30 minutes. Be aware that the
103 longer the Storage daemon waits for a Client, the more
104 resources will be tied up.
106 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
107 \index[sd]{Maximum Concurrent Jobs}
108 \index[sd]{Directive!Maximum Concurrent Jobs}
109 where \lt{}number\gt{} is the maximum number of Jobs that should run
110 concurrently. The default is set to 10, but you may set it to a larger
111 number. Each contact from the Director (e.g. status request, job start
112 request) is considered as a Job, so if you want to be able to do a {\bf
113 status} request in the console at the same time as a Job is running, you
114 will need to set this value greater than 1. To run simultaneous Jobs,
115 you will need to set a number of other directives in the Director's
116 configuration file. Which ones you set depend on what you want, but you
117 will almost certainly need to set the {\bf Maximum Concurrent Jobs} in
118 the Storage resource in the Director's configuration file and possibly
119 those in the Job and Client resources.
121 \item [SDAddresses = \lt{}IP-address-specification\gt{}]
122 \index[sd]{SDAddresses}
123 \index[sd]{Directive!SDAddresses}
124 Specify the ports and addresses on which the Storage daemon will listen
125 for Director connections. Normally, the default is sufficient and you
126 do not need to specify this directive. Probably the simplest way to
127 explain how this directive works is to show an example:
131 SDAddresses = { ip = {
132 addr = 1.2.3.4; port = 1205; }
134 addr = 1.2.3.4; port = http; }
147 addr = 201:220:222::2
150 addr = bluedot.thun.net
156 where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
157 can be specified as either a dotted quadruple, or IPv6 colon notation, or as
158 a symbolic name (only in the ip specification). Also, port can be specified
159 as a number or as the mnemonic value from the /etc/services file. If a port
160 is not specified, the default will be used. If an ip section is specified,
161 the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
162 only IPv4 resolutions will be permitted, and likewise with ip6.
164 Using this directive, you can replace both the SDPort and SDAddress
165 directives shown below.
167 \item [SDPort = \lt{}port-number\gt{}]
169 \index[sd]{Directive!SDPort}
170 Specifies port number on which the Storage daemon listens for Director
171 connections. The default is 9103.
173 \item [SDAddress = \lt{}IP-Address\gt{}]
174 \index[sd]{SDAddress}
175 \index[sd]{Directive!SDAddress}
176 This directive is optional, and if it is specified, it will cause the
177 Storage daemon server (for Director and File daemon connections) to bind
178 to the specified {\bf IP-Address}, which is either a domain name or an
179 IP address specified as a dotted quadruple. If this directive is not
180 specified, the Storage daemon will bind to any available address (the
185 The following is a typical Storage daemon Storage definition.
190 # "Global" Storage daemon configuration specifications appear
191 # under the Storage resource.
194 Name = "Storage daemon"
196 WorkingDirectory = "~/bacula/working"
197 Pid Directory = "~/bacula/working"
202 \section{Director Resource}
203 \label{DirectorResource1}
204 \index[general]{Director Resource}
205 \index[general]{Resource!Director}
207 The Director resource specifies the Name of the Director which is permitted
208 to use the services of the Storage daemon. There may be multiple Director
209 resources. The Director Name and Password must match the corresponding
210 values in the Director's configuration file.
214 \item [Name = \lt{}Director-Name\gt{}]
216 \index[sd]{Directive!Name}
217 Specifies the Name of the Director allowed to connect to the Storage daemon.
218 This directive is required.
220 \item [Password = \lt{}Director-password\gt{}]
222 \index[sd]{Directive!Password}
223 Specifies the password that must be supplied by the above named Director.
224 This directive is required.
226 \item [Monitor = \lt{}yes|no\gt{}]
228 \index[sd]{Directive!Monitor}
229 If Monitor is set to {\bf no} (default), this director will have full
230 access to this Storage daemon. If Monitor is set to {\bf yes}, this
231 director will only be able to fetch the current status of this Storage
234 Please note that if this director is being used by a Monitor, we highly
235 recommend to set this directive to {\bf yes} to avoid serious security
240 The following is an example of a valid Director resource definition:
246 Password = my_secret_password
251 \label{DeviceResource}
252 \section{Device Resource}
253 \index[general]{Resource!Device}
254 \index[general]{Device Resource}
256 The Device Resource specifies the details of each device (normally a tape
257 drive) that can be used by the Storage daemon. There may be multiple
258 Device resources for a single Storage daemon. In general, the properties
259 specified within the Device resource are specific to the Device.
263 \item [Name = {\it Device-Name}]
265 \index[sd]{Directive!Name}
266 Specifies the Name that the Director will use when asking to backup or
267 restore to or from to this device. This is the logical Device name, and may
268 be any string up to 127 characters in length. It is generally a good idea to
269 make it correspond to the English name of the backup device. The physical
270 name of the device is specified on the {\bf Archive Device} directive
271 described below. The name you specify here is also used in your Director's
273 \ilink{Device directive}{StorageResource2} in its Storage
276 \item [Archive Device = {\it name-string}]
277 \index[sd]{Archive Device}
278 \index[sd]{Directive!Archive Device}
279 The specified {\bf name-string} gives the system file name of the storage
280 device managed by this storage daemon. This will usually be the device file
281 name of a removable storage device (tape drive), for example "{\bf
282 /dev/nst0}" or "{\bf /dev/rmt/0mbn}". For a DVD-writer, it will be for
283 example {\bf /dev/hdc}. It may also be a directory name if you are archiving
284 to disk storage. In this case, you must supply the full absolute path to the
285 directory. When specifying a tape device, it is preferable that the
286 "non-rewind" variant of the device file name be given. In addition, on
287 systems such as Sun, which have multiple tape access methods, you must be
288 sure to specify to use Berkeley I/O conventions with the device. The {\bf b}
289 in the Solaris (Sun) archive specification {\bf /dev/rmt/0mbn} is what is
290 needed in this case. Bacula does not support SysV tape drive behavior.
292 As noted above, normally the Archive Device is the name of a tape drive, but
293 you may also specify an absolute path to an existing directory. If the Device
294 is a directory Bacula will write to file storage in the specified directory,
295 and the filename used will be the Volume name as specified in the Catalog.
296 If you want to write into more than one directory (i.e. to spread the load to
297 different disk drives), you will need to define two Device resources, each
298 containing an Archive Device with a different directory.
300 In addition to a tape device name or a directory name, Bacula will accept the
301 name of a FIFO. A FIFO is a special kind of file that connects two programs
302 via kernel memory. If a FIFO device is specified for a backup operation, you
303 must have a program that reads what Bacula writes into the FIFO. When the
304 Storage daemon starts the job, it will wait for {\bf MaximumOpenWait} seconds
305 for the read program to start reading, and then time it out and terminate
306 the job. As a consequence, it is best to start the read program at the
307 beginning of the job perhaps with the {\bf RunBeforeJob} directive. For this
308 kind of device, you never want to specify {\bf AlwaysOpen}, because you want
309 the Storage daemon to open it only when a job starts, so you must explicitly
310 set it to {\bf No}. Since a FIFO is a one way device, Bacula will not attempt
311 to read a label of a FIFO device, but will simply write on it. To create a
312 FIFO Volume in the catalog, use the {\bf add} command rather than the {\bf
313 label} command to avoid attempting to write a label.
321 Archive Device = /tmp/fifo
332 During a restore operation, if the Archive Device is a FIFO, Bacula will
333 attempt to read from the FIFO, so you must have an external program that
334 writes into the FIFO. Bacula will wait {\bf MaximumOpenWait} seconds for the
335 program to begin writing and will then time it out and terminate the job. As
336 noted above, you may use the {\bf RunBeforeJob} to start the writer program
337 at the beginning of the job.
339 The Archive Device directive is required.
341 \item [Device Type = {\it type-specification}]
342 \index[sd]{Device Type}
343 \index[sd]{Directive!Device Type}
344 The Device Type specification allows you to explicitly tell Bacula
345 what kind of device you are defining. It the {\it type-specification}
346 may be one of the following:
349 Tells Bacula that the device is a file. It may either be a
350 file defined on fixed medium or a removable filesystem such as
351 USB. All files must be random access devices.
353 The device is a tape device and thus is sequential access. Tape devices
354 are controlled using ioctl() calls.
356 The device is a first-in-first out sequential access read-only
357 or write-only device.
359 The device is a DVD. DVDs are sequential access for writing, but
360 random access for reading.
363 The Device Type directive is not required, and if not specified, Bacula
364 will attempt to guess what kind of device has been specified using the
365 Archive Device specification supplied. There are several advantages to
366 explicitly specifying the Device Type. First, on some systems, block and
367 character devices have the same type, which means that on those systems,
368 Bacula is unlikely to be able to correctly guess that a device is a DVD.
369 Secondly, if you explicitly specify the Device Type, the mount point
370 need not be defined until the device is opened. This is the case with
371 most removable devices such as USB that are mounted by the HAL daemon.
372 If the Device Type is not explicitly specified, then the mount point
373 must exist when the Storage daemon starts.
375 This directive was implemented in Bacula version 1.38.6.
378 \item [Media Type = {\it name-string}]
379 \index[sd]{Media Type}
380 \index[sd]{Directive!Media Type}
381 The specified {\bf name-string} names the type of media supported by this
382 device, for example, "DLT7000". Media type names are arbitrary in that you
383 set them to anything you want, but they must be known to the volume
384 database to keep track of which storage daemons can read which volumes. In
385 general, each different storage type should have a unique Media Type
386 associated with it. The same {\bf name-string} must appear in the
387 appropriate Storage resource definition in the Director's configuration
390 Even though the names you assign are arbitrary (i.e. you choose the name
391 you want), you should take care in specifying them because the Media Type
392 is used to determine which storage device Bacula will select during
393 restore. Thus you should probably use the same Media Type specification
394 for all drives where the Media can be freely interchanged. This is not
395 generally an issue if you have a single Storage daemon, but it is with
396 multiple Storage daemons, especially if they have incompatible media.
398 For example, if you specify a Media Type of "DDS-4" then during the
399 restore, Bacula will be able to choose any Storage Daemon that handles
400 "DDS-4". If you have an autochanger, you might want to name the Media Type
401 in a way that is unique to the autochanger, unless you wish to possibly use
402 the Volumes in other drives. You should also ensure to have unique Media
403 Type names if the Media is not compatible between drives. This
404 specification is required for all devices.
406 In addition, if you are using disk storage, each Device resource will
407 generally have a different mount point or directory. In order for
408 Bacula to select the correct Device resource, each one must have a
412 \item [Autochanger = {\it Yes|No}]
413 \index[sd]{Autochanger}
414 \index[sd]{Directive!Autochanger}
415 If {\bf Yes}, this device belongs to an automatic tape changer, and you
416 must specify an {\bf Autochanger} resource that points to the {\bf
417 Device} resources. You must also specify a
418 {\bf Changer Device}. If the Autochanger directive is set to {\bf
419 No} (default), the volume must be manually changed. You should also
420 have an identical directive to the
421 \ilink{Storage resource}{Autochanger1} in the Director's
422 configuration file so that when labeling tapes you are prompted for the slot.
424 \item [Changer Device = {\it name-string}]
425 \index[sd]{Changer Device}
426 \index[sd]{Directive!Changer Device}
427 The specified {\bf name-string} must be the {\bf generic SCSI} device
428 name of the autochanger that corresponds to the normal read/write
429 {\bf Archive Device} specified in the Device resource. This
430 generic SCSI device name should be specified if you have an autochanger
431 or if you have a standard tape drive and want to use the
432 {\bf Alert Command} (see below). For example, on Linux systems, for
433 an Archive Device name of {\bf /dev/nst0}, you would specify {\bf
434 /dev/sg0} for the Changer Device name. Depending on your exact
435 configuration, and the number of autochangers or the type of
436 autochanger, what you specify here can vary. This directive is
437 optional. See the \ilink{ Using Autochangers}{AutochangersChapter} chapter
438 of this manual for more details of using this and the following
439 autochanger directives.
441 \item [Changer Command = {\it name-string}]
442 \index[sd]{Changer Command}
443 \index[sd]{Directive!Changer Command}
444 The {\bf name-string} specifies an external program to be called that will
445 automatically change volumes as required by {\bf Bacula}. Normally,
446 this directive will be specified only in the {\bf AutoChanger} resource,
447 which is then used for all devices. However, you may also specify
448 the different {\bf Changer Command} in each Device resource.
450 you will specify the Bacula supplied {\bf mtx-changer} script as follows:
454 Changer Command = "/path/mtx-changer %c %o %S %a %d"
458 and you will install the {\bf mtx} on your system (found in the {\bf depkgs}
459 release). An example of this command is in the default bacula-sd.conf file.
460 For more details on the substitution characters that may be specified to
461 configure your autochanger please see the
462 \ilink{Autochangers}{AutochangersChapter} chapter of this manual.
463 For FreeBSD users, you might want to see one of the several {\bf chio}
464 scripts in {\bf examples/autochangers}.
466 \item [Alert Command = {\it name-string}]
467 \index[sd]{Alert Command}
468 The {\bf name-string} specifies an external program to be called at the
469 completion of each Job after the device is released. The purpose of this
470 command is to check for Tape Alerts, which are present when something is
471 wrong with your tape drive (at least for most modern tape drives). The same
472 substitution characters that may be specified in the Changer Command may also
473 be used in this string. For more information, please see the
474 \ilink{Autochangers}{AutochangersChapter} chapter of this manual.
477 Note, it is not necessary to have an autochanger to use this command. The
478 example below uses the {\bf tapeinfo} program that comes with the {\bf mtx}
479 package, but it can be used on any tape drive. However, you will need to
480 specify a {\bf Changer Device} directive in your Device resource (see above)
481 so that the generic SCSI device name can be edited into the command (with the
484 An example of the use of this command to print Tape Alerts in the Job report
489 Alert Command = "sh -c 'tapeinfo -f %c | grep TapeAlert'"
494 and an example output when there is a problem could be:
498 bacula-sd Alert: TapeAlert[32]: Interface: Problem with SCSI interface
499 between tape drive and initiator.
504 \item [Drive Index = {\it number}]
505 \index[sd]{Drive Index}
506 \index[sd]{Directive!Drive Index}
507 The {\bf Drive Index} that you specify is passed to the {\bf
508 mtx-changer} script and is thus passed to the {\bf mtx} program. By
509 default, the Drive Index is zero, so if you have only one drive in your
510 autochanger, everything will work normally. However, if you have
511 multiple drives, you must specify multiple Bacula Device resources (one
512 for each drive). The first Device should have the Drive Index set to 0,
513 and the second Device Resource should contain a Drive Index set to 1,
514 and so on. This will then permit you to use two or more drives in your
515 autochanger. As of Bacula version 1.38.0, using the {\bf Autochanger}
516 resource, Bacula will automatically ensure that only one drive at a time
517 uses the autochanger script, so you no longer need locking scripts as in
518 the past -- the default mtx-changer script works for any number of
521 \item [Autoselect = {\it Yes|No}]
522 \index[sd]{Autoselect}
523 \index[sd]{Directive!Autoselect}
524 If this directive is set to {\bf yes} (default), and the Device
525 belongs to an autochanger, then when the Autochanger is referenced
526 by the Director, this device can automatically be selected. If this
527 directive is set to {\bf no}, then the Device can only be referenced
528 by directly using the Device name in the Director. This is useful
529 for reserving a drive for something special such as a high priority
530 backup or restore operations.
532 \item [Maximum Changer Wait = {\it time}]
533 \index[sd]{Maximum Changer Wait}
534 \index[sd]{Directive!Maximum Changer Wait}
535 This directive specifies the maximum time in seconds for Bacula to wait
536 for an autochanger to change the volume. If this time is exceeded,
537 Bacula will invalidate the Volume slot number stored in the catalog and
538 try again. If no additional changer volumes exist, Bacula will ask the
539 operator to intervene. The default is 5 minutes.
540 % TODO: if this is the format, then maybe "5 minutes" should be in
541 % TODO: quotes? define style. see others.
543 \item [Maximum Rewind Wait = {\it time}]
544 \index[sd]{Maximum Rewind Wait}
545 \index[sd]{Directive!Maximum Rewind Wait}
546 This directive specifies the maximum time in seconds for Bacula to wait
547 for a rewind before timing out. If this time is exceeded,
548 Bacula will cancel the job. The default is 5 minutes.
550 \item [Maximum Open Wait = {\it time}]
551 \index[sd]{Maximum Open Wait}
552 \index[sd]{Directive!Maximum Open Wait}
553 This directive specifies the maximum time in seconds for Bacula to wait
554 for a open before timing out. If this time is exceeded,
555 Bacula will cancel the job. The default is 5 minutes.
557 \item [Always Open = {\it Yes|No}]
558 \index[sd]{Always Open}
559 \index[sd]{Directive!Always Open}
560 If {\bf Yes} (default), Bacula will always keep the device open unless
561 specifically {\bf unmounted} by the Console program. This permits
562 Bacula to ensure that the tape drive is always available, and properly
563 positioned. If you set
564 {\bf AlwaysOpen} to {\bf no} {\bf Bacula} will only open the drive when
565 necessary, and at the end of the Job if no other Jobs are using the
566 drive, it will be freed. The next time Bacula wants to append to a tape
567 on a drive that was freed, Bacula will rewind the tape and position it to
568 the end. To avoid unnecessary tape positioning and to minimize
569 unnecessary operator intervention, it is highly recommended that {\bf
570 Always Open = yes}. This also ensures that the drive is available when
573 If you have {\bf Always Open = yes} (recommended) and you want to use the
574 drive for something else, simply use the {\bf unmount} command in the Console
575 program to release the drive. However, don't forget to remount the drive with
576 {\bf mount} when the drive is available or the next Bacula job will block.
578 For File storage, this directive is ignored. For a FIFO storage device, you
579 must set this to {\bf No}.
581 Please note that if you set this directive to {\bf No} Bacula will release
582 the tape drive between each job, and thus the next job will rewind the tape
583 and position it to the end of the data. This can be a very time consuming
584 operation. In addition, with this directive set to no, certain multiple
585 drive autochanger operations will fail. We strongly recommend to keep
586 {\bf Always Open} set to {\bf Yes}
588 \item [Volume Poll Interval = {\it time}]
589 \index[sd]{Volume Poll Interval}
590 \index[sd]{Directive!Volume Poll Interval}
591 If the time specified on this directive is non-zero, after asking the
592 operator to mount a new volume Bacula will periodically poll (or read) the
593 drive at the specified interval to see if a new volume has been mounted. If
594 the time interval is zero (the default), no polling will occur. This
595 directive can be useful if you want to avoid operator intervention via the
596 console. Instead, the operator can simply remove the old volume and insert
597 the requested one, and Bacula on the next poll will recognize the new tape
598 and continue. Please be aware that if you set this interval too small, you
599 may excessively wear your tape drive if the old tape remains in the drive,
600 since Bacula will read it on each poll. This can be avoided by ejecting the
601 tape using the {\bf Offline On Unmount} and the {\bf Close on Poll}
603 However, if you are using a Linux 2.6 kernel or other OSes
604 such as FreeBSD or Solaris, the Offline On Unmount will leave the drive
605 with no tape, and Bacula will not be able to properly open the drive and
606 may fail the job. For more information on this problem, please see the
607 \ilink{description of Offline On Unmount}{NoTapeInDrive} in the Tape
610 \item [Close on Poll= {\it Yes|No}]
611 \index[sd]{Close on Poll}
612 \index[sd]{Directive!Close on Poll}
613 If {\bf Yes}, Bacula close the device (equivalent to an unmount except no
614 mount is required) and reopen it at each poll. Normally this is not too
615 useful unless you have the {\bf Offline on Unmount} directive set, in which
616 case the drive will be taken offline preventing wear on the tape during any
617 future polling. Once the operator inserts a new tape, Bacula will recognize
618 the drive on the next poll and automatically continue with the backup.
619 Please see above more more details.
621 \item [Maximum Open Wait = {\it time}]
622 \index[sd]{Maximum Open Wait}
623 \index[sd]{Directive!Maximum Open Wait}
624 This directive specifies the maximum amount of time in seconds that
625 Bacula will wait for a device that is busy. The default is 5 minutes.
626 If the device cannot be obtained, the current Job will be terminated in
627 error. Bacula will re-attempt to open the drive the next time a Job
628 starts that needs the the drive.
630 \label{removablemedia}
631 \item [Removable media = {\it Yes|No}]
632 \index[sd]{Removable media}
633 \index[sd]{Directive!Removable media}
634 If {\bf Yes}, this device supports removable media (for example, tapes
635 or CDs). If {\bf No}, media cannot be removed (for example, an
636 intermediate backup area on a hard disk). If {\bf Removable media} is
637 enabled on a File device (as opposed to a tape) the Storage daemon will
638 assume that device may be something like a USB device that can be
639 removed or a simply a removable harddisk. When attempting to open
640 such a device, if the Volume is not found (for File devices, the Volume
641 name is the same as the Filename), then the Storage daemon will search
642 the entire device looking for likely Volume names, and for each one
643 found, it will ask the Director if the Volume can be used. If so,
644 the Storage daemon will use the first such Volume found. Thus it
645 acts somewhat like a tape drive -- if the correct Volume is not found,
646 it looks at what actually is found, and if it is an appendable Volume,
649 If the removable medium is not automatically mounted (e.g. udev), then
650 you might consider using additional Storage daemon device directives
651 such as {\bf Requires Mount}, {\bf Mount Point}, {\bf Mount Command},
652 and {\bf Unmount Command}, all of which can be used in conjunction with
653 {\bf Removable Media}.
656 \item [Random access = {\it Yes|No}]
657 \index[sd]{Random access}
658 \index[sd]{Directive!Random access}
659 If {\bf Yes}, the archive device is assumed to be a random access medium
660 which supports the {\bf lseek} (or {\bf lseek64} if Largefile is enabled
661 during configuration) facility. This should be set to {\bf Yes} for all
662 file systems such as DVD, USB, and fixed files. It should be set to
663 {\bf No} for non-random access devices such as tapes and named pipes.
666 \item [Requires Mount = {\it Yes|No}]
667 \index[sd]{Requires Mount }
668 When this directive is enabled, the Storage daemon will submit
669 a {\bf Mount Command} before attempting to open the device.
670 You must set this directive to {\bf yes} for DVD-writers and removable
671 file systems such as USB devices that are not automatically mounted
672 by the operating system when plugged in or opened by Bacula.
673 It should be set to {\bf no} for
674 all other devices such as tapes and fixed filesystems. It should also
675 be set to {\bf no} for any removable device that is automatically
676 mounted by the operating system when opened (e.g. USB devices mounted
677 by udev or hotplug). This directive
678 indicates if the device requires to be mounted using the {\bf Mount
679 Command}. To be able to write a DVD, the following directives must also
680 be defined: {\bf Mount Point}, {\bf Mount Command}, {\bf Unmount
681 Command} and {\bf Write Part Command}.
683 \item [Mount Point = {\it directory}]
684 \index[sd]{Mount Point}
685 Directory where the device can be mounted.
686 This directive is used only
687 for devices that have {\bf Requires Mount} enabled such as DVD or
690 \item [Mount Command = {\it name-string}]
691 \index[sd]{Mount Command}
692 This directive specifies the command that must be executed to mount
693 devices such as DVDs and many USB devices. For DVDs, the
694 device is written directly, but the mount command is necessary in
695 order to determine the free space left on the DVD. Before the command is
696 executed, \%a is replaced with the Archive Device, and \%m with the Mount
699 Most frequently, for a DVD, you will define it as follows:
703 Mount Command = "/bin/mount -t iso9660 -o ro %a %m"
707 However, if you have defined a mount point in /etc/fstab, you might be
708 able to use a mount command such as:
712 Mount Command = "/bin/mount /media/dvd"
716 See the \ilink {Edit Codes}{mountcodes} section below for more details of
717 the editing codes that can be used in this directive.
719 If you need to specify multiple commands, create a shell script.
721 \item [Unmount Command = {\it name-string}]
722 \index[sd]{Unmount Command}
723 This directive specifies the command that must be executed to unmount
724 devices such as DVDs and many USB devices. Before the command is
725 executed, \%a is replaced with the Archive Device, and \%m with the Mount
728 Most frequently, you will define it as follows:
732 Unmount Command = "/bin/umount %m"
736 See the \ilink {Edit Codes}{mountcodes} section below for more details of
737 the editing codes that can be used in this directive.
739 If you need to specify multiple commands, create a shell script.
741 \item [Minimum block size = {\it size-in-bytes}]
742 \index[sd]{Minimum block size}
743 \index[sd]{Directive!Minimum block size}
744 On most modern tape drives, you will not need or want to specify this
745 directive, and if you do so, it will be to make Bacula use fixed block
746 sizes. This statement applies only to non-random access devices (e.g.
747 tape drives). Blocks written by the storage daemon to a non-random
748 archive device will never be smaller than the given {\bf size-in-bytes}.
749 The Storage daemon will attempt to efficiently fill blocks with data
750 received from active sessions but will, if necessary, add padding to a
751 block to achieve the required minimum size.
753 To force the block size to be fixed, as is the case for some non-random
754 access devices (tape drives), set the {\bf Minimum block size} and the
755 {\bf Maximum block size} to the same value (zero included). The default
756 is that both the minimum and maximum block size are zero and the default
757 block size is 64,512 bytes.
759 For example, suppose you want a fixed block size of 100K bytes, then you
765 Minimum block size = 100K
766 Maximum block size = 100K
771 Please note that if you specify a fixed block size as shown above, the tape
772 drive must either be in variable block size mode, or if it is in fixed block
773 size mode, the block size (generally defined by {\bf mt}) {\bf must} be
774 identical to the size specified in Bacula -- otherwise when you attempt to
775 re-read your Volumes, you will get an error.
777 If you want the block size to be variable but with a 64K minimum and 200K
778 maximum (and default as well), you would specify:
783 Minimum block size = 64K
784 Maximum blocksize = 200K
789 \item [Maximum block size = {\it size-in-bytes}]
790 \index[sd]{Maximum block size}
791 \index[sd]{Directive!Maximum block size}
792 On most modern tape drives, you will not need to specify this directive.
793 If you do so, it will most likely be to use fixed block sizes (see
794 Minimum block size above). The Storage daemon will always attempt to
795 write blocks of the specified {\bf size-in-bytes} to the archive device.
796 As a consequence, this statement specifies both the default block size
797 and the maximum block size. The size written never exceed the given
798 {\bf size-in-bytes}. If adding data to a block would cause it to exceed
799 the given maximum size, the block will be written to the archive device,
800 and the new data will begin a new block.
802 If no value is specified or zero is specified, the Storage daemon will
803 use a default block size of 64,512 bytes (126 * 512).
805 \item [Hardware End of Medium = {\it Yes|No}]
806 \index[sd]{Hardware End of Medium}
807 \index[sd]{Directive!Hardware End of Medium}
808 If {\bf No}, the archive device is not required to support end of medium
809 ioctl request, and the storage daemon will use the forward space file
810 function to find the end of the recorded data. If {\bf Yes}, the archive
811 device must support the {\tt ioctl} {\tt MTEOM} call, which will position the
812 tape to the end of the recorded data. In addition, your SCSI driver must keep
813 track of the file number on the tape and report it back correctly by the
814 {\bf MTIOCGET} ioctl. Note, some SCSI drivers will correctly forward space to
815 the end of the recorded data, but they do not keep track of the file number.
816 On Linux machines, the SCSI driver has a {\bf fast-eod} option, which if set
817 will cause the driver to lose track of the file number. You should ensure
818 that this option is always turned off using the {\bf mt} program.
820 Default setting for Hardware End of Medium is {\bf Yes}. This function is
821 used before appending to a tape to ensure that no previously written data is
822 lost. We recommend if you have a non-standard or unusual tape drive that you
823 use the {\bf btape} program to test your drive to see whether or not it
824 supports this function. All modern (after 1998) tape drives support this
827 \item [Fast Forward Space File = {\it Yes|No}]
828 \index[sd]{Fast Forward Space File}
829 \index[sd]{Directive!Fast Forward Space File}
830 If {\bf No}, the archive device is not required to support keeping track of
831 the file number ({\bf MTIOCGET} ioctl) during forward space file. If {\bf
832 Yes}, the archive device must support the {\tt ioctl} {\tt MTFSF} call, which
833 virtually all drivers support, but in addition, your SCSI driver must keep
834 track of the file number on the tape and report it back correctly by the
835 {\bf MTIOCGET} ioctl. Note, some SCSI drivers will correctly forward space,
836 but they do not keep track of the file number or more seriously, they do not
837 report end of medium.
839 Default setting for Fast Forward Space File is {\bf Yes}.
841 \item [Use MTIOCGET = {\it Yes|No}]
842 \index[sd]{Use MTIOCGET}
843 \index[sd]{Directive!Use MTIOCGET}
844 If {\bf No}, the operating system is not required to support keeping track of
845 the file number and reporting it in the ({\bf MTIOCGET} ioctl). The default
846 is {\bf Yes}. If you must set this to No, Bacula will do the proper file
847 position determination, but it is very unfortunate because it means that
848 tape movement is very inefficient.
849 Fortunately, this operation system deficiency seems to be the case only
850 on a few *BSD systems. Operating systems known to work correctly are
851 Solaris, Linux and FreeBSD.
853 \item [BSF at EOM = {\it Yes|No}]
854 \index[sd]{BSF at EOM}
855 \index[sd]{Directive!BSF at EOM}
856 If {\bf No}, the default, no special action is taken by Bacula with the End
857 of Medium (end of tape) is reached because the tape will be positioned after
858 the last EOF tape mark, and Bacula can append to the tape as desired.
859 However, on some systems, such as FreeBSD, when Bacula reads the End of
860 Medium (end of tape), the tape will be positioned after the second EOF tape
861 mark (two successive EOF marks indicated End of Medium). If Bacula appends
862 from that point, all the appended data will be lost. The solution for such
863 systems is to specify {\bf BSF at EOM} which causes Bacula to backspace over
864 the second EOF mark. Determination of whether or not you need this directive
865 is done using the {\bf test} command in the {\bf btape} program.
867 \item [TWO EOF = {\it Yes|No}]
869 \index[sd]{Directive!TWO EOF}
870 If {\bf Yes}, Bacula will write two end of file marks when terminating a tape
871 -- i.e. after the last job or at the end of the medium. If {\bf No}, the
872 default, Bacula will only write one end of file to terminate the tape.
874 \item [Backward Space Record = {\it Yes|No}]
875 \index[sd]{Backward Space Record}
876 \index[sd]{Directive!Backward Space Record}
877 If {\it Yes}, the archive device supports the {\tt MTBSR ioctl} to backspace
878 records. If {\it No}, this call is not used and the device must be rewound
879 and advanced forward to the desired position. Default is {\bf Yes} for non
880 random-access devices. This function if enabled is used at the end of a
881 Volume after writing the end of file and any ANSI/IBM labels to determine whether
882 or not the last block was written correctly. If you turn this function off,
883 the test will not be done. This causes no harm as the re-read process is
884 precautionary rather than required.
886 \item [Backward Space File = {\it Yes|No}]
887 \index[sd]{Backward Space File}
888 \index[sd]{Directive!Backward Space File}
889 If {\it Yes}, the archive device supports the {\bf MTBSF} and {\bf MTBSF
890 ioctl}s to backspace over an end of file mark and to the start of a file. If
891 {\it No}, these calls are not used and the device must be rewound and
892 advanced forward to the desired position. Default is {\bf Yes} for non
893 random-access devices.
895 \item [Forward Space Record = {\it Yes|No}]
896 \index[sd]{Forward Space Record}
897 \index[sd]{Directive!Forward Space Record}
898 If {\it Yes}, the archive device must support the {\bf MTFSR ioctl} to
899 forward space over records. If {\bf No}, data must be read in order to
900 advance the position on the device. Default is {\bf Yes} for non
901 random-access devices.
903 \item [Forward Space File = {\it Yes|No}]
904 \index[sd]{Forward Space File}
905 \index[sd]{Directive!Forward Space File}
906 If {\bf Yes}, the archive device must support the {\tt MTFSF ioctl} to
907 forward space by file marks. If {\it No}, data must be read to advance the
908 position on the device. Default is {\bf Yes} for non random-access devices.
910 \item [Offline On Unmount = {\it Yes|No}]
911 \index[sd]{Offline On Unmount}
912 \index[sd]{Directive!Offline On Unmount}
913 The default for this directive is {\bf No}. If {\bf Yes} the archive device
914 must support the {\tt MTOFFL ioctl} to rewind and take the volume offline. In
915 this case, Bacula will issue the offline (eject) request before closing the
916 device during the {\bf unmount} command. If {\bf No} Bacula will not attempt
917 to offline the device before unmounting it. After an offline is issued, the
918 cassette will be ejected thus {\bf requiring operator intervention} to
919 continue, and on some systems require an explicit load command to be issued
920 ({\bf mt -f /dev/xxx load}) before the system will recognize the tape. If you
921 are using an autochanger, some devices require an offline to be issued prior
922 to changing the volume. However, most devices do not and may get very
925 If you are using a Linux 2.6 kernel or other OSes
926 such as FreeBSD or Solaris, the Offline On Unmount will leave the drive
927 with no tape, and Bacula will not be able to properly open the drive and
928 may fail the job. For more information on this problem, please see the
929 \ilink{description of Offline On Unmount}{NoTapeInDrive} in the Tape
933 \item [Maximum Volume Size = {\it size}]
934 \index[sd]{Maximum Volume Size}
935 \index[sd]{Directive!Maximum Volume Size}
936 No more than {\bf size} bytes will be written onto a given volume on the
937 archive device. This directive is used mainly in testing Bacula to
938 simulate a small Volume. It can also be useful if you wish to limit the
939 size of a File Volume to say less than 2GB of data. In some rare cases
940 of really antiquated tape drives that do not properly indicate when the
941 end of a tape is reached during writing (though I have read about such
942 drives, I have never personally encountered one). Please note, this
943 directive is deprecated (being phased out) in favor of the {\bf Maximum
944 Volume Bytes} defined in the Director's configuration file.
946 \item [Maximum File Size = {\it size}]
947 \index[sd]{Maximum File Size}
948 \index[sd]{Directive!Maximum File Size}
949 No more than {\bf size} bytes will be written into a given logical file
950 on the volume. Once this size is reached, an end of file mark is
951 written on the volume and subsequent data are written into the next
952 file. Breaking long sequences of data blocks with file marks permits
953 quicker positioning to the start of a given stream of data and can
954 improve recovery from read errors on the volume. The default is one
955 Gigabyte. This directive creates EOF marks only on tape media.
956 However, regardless of the medium type (tape, disk, DVD, ...) each time
957 a the Maximum File Size is exceeded, a record is put into the catalog
958 database that permits seeking to that position on the medium for
959 restore operations. If you set this to a small value (e.g. 1MB),
960 you will generate lots of database records (JobMedia) and may
961 significantly increase CPU/disk overhead.
963 Note, this directive does not limit the size of Volumes that Bacula
964 will create regardless of whether they are tape or disk volumes. It
965 changes only the number of EOF marks on a tape and the number of
966 block positioning records (see below) that are generated. If you
967 want to limit the size of all Volumes for a particular device, use
968 the {\bf Maximum Volume Size} directive (above), or use the
969 {\bf Maximum Volume Bytes} directive in the Director's Pool resource,
970 which does the same thing but on a Pool (Volume) basis.
972 \item [Block Positioning = {\it yes|no}]
973 \index[sd]{Block Positioning}
974 \index[sd]{Directive!Block Positioning}
975 This directive tells Bacula not to use block positioning when doing restores.
976 Turning this directive off can cause Bacula to be {\bf extremely} slow
977 when restoring files. You might use this directive if you wrote your
978 tapes with Bacula in variable block mode (the default), but your drive
979 was in fixed block mode. The default is {\bf yes}.
981 \item [Maximum Network Buffer Size = {\it bytes}]
982 \index[sd]{Maximum Network Buffer Size}
983 \index[sd]{Directive!Maximum Network Buffer Size}
984 where {\it bytes} specifies the initial network buffer size to use with the
985 File daemon. This size will be adjusted down if it is too large until
986 it is accepted by the OS. Please use care in setting this value since if
987 it is too large, it will be trimmed by 512 bytes until the OS is happy,
988 which may require a large number of system calls. The default value is
991 The default size was chosen to be relatively large but not too big in
992 the case that you are transmitting data over Internet. It is clear that
993 on a high speed local network, you can increase this number and improve
994 performance. For example, some users have found that if you use a value
995 of 65,536 bytes they get five to ten times the throughput. Larger values for
996 most users don't seem to improve performance. If you are interested
997 in improving your backup speeds, this is definitely a place to
998 experiment. You will probably also want to make the corresponding change
999 in each of your File daemons conf files.
1002 \item [Maximum Spool Size = {\it bytes}]
1003 \index[sd]{Maximum Spool Size}
1004 \index[sd]{Directive!Maximum Spool Size}
1005 where the bytes specify the maximum spool size for all jobs that are running.
1006 The default is no limit.
1008 \item [Maximum Job Spool Size = {\it bytes}]
1009 \index[sd]{Maximum Job Spool Size}
1010 \index[sd]{Directive!Maximum Job Spool Size}
1011 where the bytes specify the maximum spool size for any one job that is
1012 running. The default is no limit.
1013 This directive is implemented only in version 1.37 and later.
1015 \item [Spool Directory = {\it directory}]
1016 \index[sd]{Spool Directory}
1017 \index[sd]{Directive!Spool Directory}
1018 specifies the name of the directory to be used to store the spool files for
1019 this device. This directory is also used to store temporary part files when
1020 writing to a device that requires mount (DVD). The default is to use the
1023 \item [Maximum Part Size = {\it bytes}]
1024 \index[sd]{Maximum Part Size}
1025 \index[sd]{Directive!Maximum Part Size}
1026 This is the maximum size of a volume part file. The default is no limit.
1027 This directive is implemented only in version 1.37 and later.
1029 If the device requires mount, it is transferred to the device when this size
1030 is reached. In this case, you must take care to have enough disk space left
1031 in the spool directory.
1033 Otherwise, it is left on the hard disk.
1035 It is ignored for tape and FIFO devices.

1045 Before submitting the {\bf Mount Command}, {\bf Unmount Command},
1046 {\bf Write Part Command}, or {\bf Free Space Command} directives
1047 to the operating system, Bacula performs character substitution of the

1066 All the directives in this section are implemented only in
1067 Bacula version 1.37 and later and hence are available in version 1.38.6.
1069 As of version 1.39.5, the directives
1070 "Requires Mount", "Mount Point", "Mount Command", and "Unmount Command"
1071 apply to removable filesystems such as USB in addition to DVD.
1075 \item [Requires Mount = {\it Yes|No}]
1076 \index[sd]{Requires Mount}
1077 \index[sd]{Directive!Requires Mount}
1078 You must set this directive to {\bf yes} for DVD-writers, and to {\bf no} for
1079 all other devices (tapes/files). This directive indicates if the device
1080 requires to be mounted to be read, and if it must be written in a special way.
1081 If it set, {\bf Mount Point}, {\bf Mount Command}, {\bf Unmount Command} and
1082 {\bf Write Part Command} directives must also be defined.
1084 \item [Mount Point = {\it directory}]
1085 \index[sd]{Mount Point}
1086 \index[sd]{Directive!Mount Point}
1087 Directory where the device can be mounted.
1089 \item [Mount Command = {\it name-string}]
1090 \index[sd]{Mount Command}
1091 \index[sd]{Directive!Mount Command}
1092 Command that must be executed to mount the device. Before the command is
1093 executed, \%a is replaced with the Archive Device, and \%m with the Mount
1096 Most frequently, you will define it as follows:
1100 Mount Command = "/bin/mount -t iso9660 -o ro %a %m"
1104 For some media, you may need multiple commands. If so, it is recommended
1105 that you use a shell script instead of putting them all into the Mount
1106 Command. For example, instead of this:
1110 Mount Command = "/usr/local/bin/mymount"
1114 Where that script contains:
1119 ndasadmin enable -s 1 -o w
1121 mount /dev/ndas-00323794-0p1 /backup
1125 Similar consideration should be given to all other Command parameters.

1128 \index[sd]{Unmount Command}
1129 \index[sd]{Directive!Unmount Command}
1130 Command that must be executed to unmount the device. Before the command is
1131 executed, \%a is replaced with the Archive Device, and \%m with the Mount
1134 Most frequently, you will define it as follows:
1138 Unmount Command = "/bin/umount %m"
1142 If you need to specify multiple commands, create a shell script.

1145 \index[sd]{Write Part Command}
1146 \index[sd]{Directive!Write Part Command}
1147 Command that must be executed to write a part to the device. Before the
1148 command is executed, \%a is replaced with the Archive Device, \%m with the
1149 Mount Point, \%e is replaced with 1 if we are writing the first part,
1150 and with 0 otherwise, and \%v with the current part filename.
1152 For a DVD, you will most frequently specify the Bacula supplied {\bf
1153 dvd-handler} script as follows:
1157 Write Part Command = "/path/dvd-handler %a write %e %v"
1161 Where {\bf /path} is the path to your scripts install directory, and
1162 dvd-handler is the Bacula supplied script file.
1163 This command will already be present, but commented out,
1164 in the default bacula-sd.conf file. To use it, simply remove
1165 the comment (\#) symbol.
1167 If you need to specify multiple commands, create a shell script.
1170 \item [Free Space Command = {\it name-string}]
1171 \index[sd]{Free Space Command}
1172 \index[sd]{Directive!Free Space Command}
1173 Command that must be executed to check how much free space is left on the
1174 device. Before the command is executed,\%a is replaced with the Archive
1175 Device, \%m with the Mount Point, \%e is replaced with 1 if we are writing
1176 the first part, and with 0 otherwise, and \%v with the current part filename.
1178 For a DVD, you will most frequently specify the Bacula supplied {\bf
1179 dvd-handler} script as follows:
1183 Free Space Command = "/path/dvd-handler %a free"
1187 Where {\bf /path} is the path to your scripts install directory, and
1188 dvd-handler is the Bacula supplied script file.
1189 If you want to specify your own command, please look at the code of
1190 dvd-handler to see what output Bacula expects from this command.
1191 This command will already be present, but commented out,
1192 in the default bacula-sd.conf file. To use it, simply remove
1193 the comment (\#) symbol.
1195 If you do not set it, Bacula will expect there is always free space on the
1198 If you need to specify multiple commands, create a shell script.

1218 If {\bf Yes}, permits this device to automatically label blank media
1219 without an explicit operator command. It does so by using an internal
1220 algorithm as defined on the \ilink{Label Format}{Label} record in each
1221 Pool resource. If this is {\bf No} as by default, Bacula will label
1222 tapes only by specific operator command ({\bf label} in the Console) or
1223 when the tape has been recycled. The automatic labeling feature is most
1224 useful when writing to disk rather than tape volumes.

1228 \index[sd]{Directive!Automatic mount}
1229 If {\bf Yes} (the default), permits the daemon to examine the device to
1230 determine if it contains a Bacula labeled volume. This is done
1231 initially when the daemon is started, and then at the beginning of each
1232 job. This directive is particularly important if you have set
1233 {\bf Always Open = no} because it permits Bacula to attempt to read the
1234 device before asking the system operator to mount a tape. However,
1235 please note that the tape must be mounted before the job begins.
