- Release Notes for Bacula 1.37.12
-
- Bacula code: Total files = 419 Total lines = 124,877 (*.h *.c *.in)
-
-Note! The DB has been upgraded from version 8 to 9 and requres
-a DB upgrade.
-
-Major Changes:
-- The Python interface has been updated to be object oriented.
-- This version has a new DIR <--> SD protocol. Both must be
- upgraded at the same time.
-- This version has a new database format that is not compatible
- with previous databases. The upgrade scripts should work, but
- they are not yet tested.
-- SQLite3 support, but it seems to run at 1/2 to 1/4 the speed of
- SQLite2.
-- First cut at ANSI labels.
-- New communications protocol between DIR and SD to reserve
- drives. The DIR and SD are no longer compatible with 1.36 or
- lower versions.
-- Python Event support has been added. See below for
- configuration and details.
-- DVD writing support, using parts, and a lot of new directives in
- the Device resource of the Storage configuration file.
-- Seven new options keywords in a FileSet resource:
- ignorecase, fstype, hfsplussupport, wilddir, wildfile, regexdir,
- and regexfile. See below for details.
-- Restore of all files for a Job or set of jobs even if the file
- records have been removed from the catalog.
-- Restore of a directory (non-recursive, i.e. only one level).
-- Support for Unicode filenames on Win32.
-- Support for TLS (ssl) between all the daemon connections.
-
-New Directives:
-- New Run directive in Job resource of DIR. It permits
- cloning of jobs. To clone a copy of the current job, use
- Run = "job-name level=%l since=\"%s\""
- Note, job-name is normally the same name as the job that
- is running but there is no restriction on what you put. If you
- want to start the job by hand and use job overrides such as
- storage=xxx, realize that the job will be started with the
- default storage values not the overrides. The level=%l guarantees
- that the chosen level of the job is the same, and the since=...
- ensures that the job uses *exactly* the same time/date for incremental
- and differential jobs. The since=... is ignored when level=Full.
- A cloned job will not start additional clones, so it is not possible
- to recurse.
-- New Options keywords in a FileSet directive:
- - WildDir xxx
- Will do a wild card match against directories (files will not
- be matched).
- - WildFile xxx
- Will do a wild card match against files (directories will not
- be matched).
- - RegexDir xxx
- Will do a regular expression match against directories (files
- will not be matched).
- - RegexFile xxx
- Will do a regular expression match against files( directories
- will not be matched).
- - IgnoreCase = yes | no
- Will ignore case in wild card and regular expression matches.
- This is handy for Windows where filename case is not significant.
- - FsType = string
- where string is a filesystem type: ext2, jfs, ntfs, proc,
- reiserfs, xfs, usbdevfs, sysfs, smbfs, iso9660. For ext3
- systems, use ext2. You may have multiple fstype directives
- and thus permit multiple filesystem types. If the type
- specified on the fstype directive does not match the
- filesystem for a particular directive, that directory will
- not be backed up. This directive can be used to prevent
- backing up non-local filesystems.
- - HFS Plus Support = yes | no
- If set, Mac OS X resource forks will be saved and restored.
-- Label Type = ANSI | IBM | Bacula
- Implemented in Director Pool resource and in SD Device resource.
- If it is specified in the SD Device resource, it will take
- precedence over the value passed from the Director to the SD.
- IBM is not yet implemented.
-- Check Labels = yes | no
- Implemented in the SD Device resource. If you intend to read
- ANSI or IBM labels, this *must* be set. Even if the volume
- is not ANSI labeled, you can set this to yes, and Bacula will
- check the label type.
-- Scripts Directory = <directory> name. Defines the directory from
- which Bacula scripts will be called for events. In fact, Bacula
- appends this name to the standard Python list of search directories,
- so the script could also be in any of the Python system directories.
-- In FileSet, you can exclude backing up of hardlinks (if you have
- a lot, it can be very expensive), by using:
- HardLinks = no
- in the Options section. Patch supplied by David R Bosso. Thanks.
-- MaximumPartSize = bytes (SD, Device resource)
- Defines the maximum part size.
-- Requires Mount = Yes/No (SD, Device resource)
- Defines if the device require to be mounted to be read, and if it
- must be written in a special way. If it set, the following directives
- must be defined in the same Device resource:
- + Mount Point = directory
- Directory where the device must be mounted.
- + Mount Command = name-string
- Command that must be executed to mount the device. Before the command
- is executed, %a is replaced with the Archive Device, and %m with the
- Mount Point.
- + Unmount Command = name-string
- Command that must be executed to unmount the device. Before the
- command is executed, %a is replaced with the Archive Device, and
- %m with the Mount Point.
- + Write Part Command = name-string
- Command that must be executed to write a part to the device. Before
- the command is executed, %a is replaced with the Archive Device, %m
- with the Mount Point, %n with the current part number (0-based),
- and %v with the current part filename.
- + Free Space Command = name-string
- Command that must be executed to check how much free space is left
- on the device. Before the command is executed, %a is replaced with
- the Archive Device, %m with the Mount Point, %n with the current part
- number (0-based), and %v with the current part filename.
-- Write Part After Job = Yes/No (DIR, Job Resource, and Schedule Resource)
- If this directive is set to yes (default no), a new part file will be
- created after the job is finished.
-
-New Commands:
-- "python restart" restarts the Python interpreter. Rather brutal, make
- sure no Python scripts are running. This permits you to change
- a Python script and get Bacula to use the new script.
-
-Items to note!!!
-- You must add --with-python=[DIR] to the configure command line
- if you want Python support. Python 2.2 and 2.3 should be automatically
- detected if in the standard place.
-- With Python 2.2 version, the link of the Director gets a few linker
- warnings due to the fact that Python pulls in some old non-secure
- libraries.
-- With Python 2.3, there are a few compiler warnings.
-- You must either create a new catalog database or upgrade your
- old database (upgrade scripts not yet tested).
-
-Other Items:
-- 2 new scripts, dvd-writepart and dvd-freespace, in the scripts directory,
- which are designed to be used as parameters to Write Part Command and
- Free Space Command. They need the dvd+rw-tools to be installed
- (http://fy.chalmers.se/~appro/linux/DVD+RW/).
-- Part files support: File volumes can now be splitted in multiple
- files, called "parts".
-
-NOTE THE FOLLOWING IS NOW OUT OF DATE!!!!
-- Python scripting support:
- A Python script will be called at particular points or conditions
- in Bacula called Events. The currently defined Events are called:
-
- StartJob, EndJob, NewVolume
-
- Where StartJob is called before the RunBeforeJob, EndJob is called
- after RunAfterJob, and NewVolume, is called before all other
- "methods" of obtaining a new Volume name, when one is needed.
-
- The Python script of the same name as the Event name (but with a .py)
- is called from the Scripts Directory (a directive defined in the
- Director resource). Note, both the Filename, and the name of
- the function in the file must correspond to the Event name.
-
- Once the Python script gets control, it can have access to Bacula
- variables by doing:
-
- import bacula
-
- The script is called with one argument, typically called jcr. This
- argument *must* be used to access each bacula function. The
- format of the call is slightly different for reading Bacula
- variable and for writing bacula variables. See below.
-
- Bacula variables can be read with:
-
- jcr.get("Variable-name")
-
- where jcr is the argument passed to the function, and Variable-name
- is on of the following:
-
- JobId, Client, Pool, Storage, Catalog, MediaType, NumVols, DirName,
- Level, Type, Job, JobName, JobStatus
-
- Bacula varibles can be set using Python keyword arguments:
-
- jcr.set(VolumeName="xyz")
-
- The two currently implemented writable "variables" are:
-
- VolumeName and JobReport
-
- It is possible to submit a Bacula run command with the following:
-
- jcr.run("run kernsave client=Matou storage=File")
-
- this function returns the JobId of the job that was started. If
- there is an error, the return value is zero.
-
- Example:
-
-== File EndJob.py ===
-import bacula
-
-def EndJob(jcr):
- jobid = jcr.get("JobId")
- client = jcr.get("Client")
- jcr.set(JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
- if (jobid < 5) :
- startid = jcr.run("run kernsave")
- print "Python started jobid=", startid
-
- return 1
-====
-
-== File NewVolume.py ===
-import bacula
-
-def NewVolume(jcr):
- jobid = jcr.get("JobId")
- print "JobId=", jobid
- client = jcr.get("Client")
- print "Client=" + client
- numvol = jcr.get("NumVols");
- print "NumVols=", numvol
- jcr.set(JobReport="New Volume set for Job.\n")
- jcr.set(VolumeName="TestA-001")
- return 1

+ Release Notes for Bacula 1.39.18
+
+ Bacula code: Total files = 448 Total lines = 150,330 (*.h *.c *.in)
+
+Warning for version 1.39.18 and greater:
+- The documentation is almost non-existent for all new features
+ except RunScripts (written and documented by Eric Bollingier).
+- If you have an old pre 1.39.18 database, you must upgrade it using
+ the upgrade_bacula_tables script. Please backup your database before
+ upgrading just in case.
+- You *should* be able to use 1.38.x FDs with version 1.39.18 Director
+ and SD providing you do not use any of the new features (runscript,
+ data encryption). It seems to work here, but we do not guarantee it.
+- Your Director and SD must be simultaneously upgraded.
+- The restore command no longer uses the MediaType as the primary method
+ of finding a suitable Storage device. Normally it will select the last
+ device used to write a Volume. If no storage device is defined, it
+ will use the old algorithm which selects the first Storage resource
+ with the correct MediaType.
+- The MD5/SHA1 hash codes kept in the database are now kept in a binary
+ format compatible with the rest of the world. If you are running verify
+ jobs, you *must* do an InitCatalog or all files will show an MD5
+ difference. Also, authentication uses the new algorithm by
+ default, but *should* accept connections from older components (FD) using
+ the old non-compatible algorithm. This has been tested, but more
+ more testing is still needed.
+- The --mandir ./configure option now points to the top level man
+ directory. The man files will be installed under mandir/man8 and
+ mandir/man1 as appropriate.
+- The "Accept Any Volume" directive has been removed. It was never
+ implemented. Bacula will always accept any valid tape that is in
+ the drive for appending.
+- To install the 1.39.18 Win32 FD, you *must* first stop any
+ previous version that is running in a DOS shell with:
+
+ net stop bacula
+
+ or select the 'Close Bacula' menu item from the Bacula tray icon,
+ you should then save your bacula-fd.conf file, and either
+ uninstall (using Uninstall.bat in the c:\bacula directory) or
+ remove the old installation by manually in a DOS shell in the
+ Bacula directory enter:
+
+ bacula-fd /remove
+
+ after that you can proceed with the installation. My experience
+ is that it does not properly create the new bacula-fd.conf file, so
+ copy the one saved to the directory you chose to install Bacula,
+ or to the directory chosen by the Installer to put the bacula-fd.conf
+ file. Then you can start Bacula in a DOS shell with:
+
+ net start baculafd
+
+ or use the Windows Control Panel->Administrative Tools->Component
+ Services menu item.
+
+
+A Lot of New features for 1.39.18:
+- Switch the Win32 build from using Microsoft C++ to using mingw32
+ cross-compiling. The inital work was done by Howard Thomson,
+ then tweaked by me. Robert Nelson then totally reworked the
+ cross-compiling code so that it not only cross-compiles, but
+ also compiles on Visual Studio, and at the same time, he added
+ all the current Unix features to the FD, such as selection on
+ drives, encryption support, building *all* the tools, ...
+ Finally, he also ported the Directory and the Storage daemon to
+ Win32.
+- Data encryption done in the Client is now supported due to code
+ submitted by Landon Fuller.
+- Bacula restore and bextract can now extract non-portable Win32 data to
+ any client (including Unix/Linux clients). Of course, in doing so,
+ the Microsoft specific permissions and ACLs will be lost. Thanks
+ to Thorsten Engel for this code.
+- The 260 character limitation for Win32 paths name lengths is now
+ eliminated thanks to Thorsted Engel.
+- Eric Bollengier wrote new RunScript directives that includes
+ the old RunBefore/AfterJob and ClientRunBefore/AfterJob features
+ plus a *lot* more, allowing you to control just about every aspect
+ of running scripts. See the manual for detailed documentation.
+- The examples directory has a new bacula_mail_summary.sh file that
+ creates a single email summary of any number of jobs. Submitted by
+ Andrew J. Millar.
+- SunOS ACLs should now work thanks to a patch from David Duchscher.
+- The database Id records should be 32/64 bit independent now. 64 bits
+ can be enabled by changing one define, but this has never been tested.
+- Apply days keyword patch from Alexander.Bergolth at wu-wien.ac.at
+ If this patch is applied, the number of days can be specified with
+ "list nextvol days=xx"
+ or
+ "status dir days=xx"
+ My use case is to be able to preview the next scheduled job (and the
+ next tape to be used) on fridays if there are no scheduled jobs during
+ the weekend. This patch was probably back ported to 1.38.x
+- Add nagios plugin to the examples directory. Submitted by
+ Christian Masopust.
+- Modify most restore error messages to be queued so that they
+ appear at the end of the job rather than mixted with the restore
+ listing where they could be "lost".
+- Apply patch supplied by user (slightly modified) to fix
+ correct detection of holes in block devices and FIFOs.
+ Bug # 506.
+- Added a report.pl program to the examples directory from Jonas Bjorklund.
+- Add enable/disable job=<job-name>. This command prevents
+ the specified job from being scheduled. Even when disabled,
+ the job can be manually started from the console.
+- Add two new queries to query.sql provided by Arno. One
+ list volumes known to the Storage device, and the other
+ lists volumes possibly needing replacement (error, ...).
+- Implement new code for changing userid and group at startup. This
+ should get Bacula into the correct groups.
+- Implement support for removable filesystems.
+- Transfer rates are now presented in a more readable format thanks
+ to a user submission.
+- SD is now aware of what volumes are mounted. More information is printed
+ in the Status report.
+- The Pool Maximum Volumes directive is now respected in all places.
+- A Storage device can now be specified in a Pool resource. It will override
+ all other Storage specifications.
+- Most but not all directives accept true/false in place of yes/no.
+- A patch from Karl Hakimian that reads JobIds, FileIndexes
+ from a database table for restore.
+- There are a number of new tables. Some such as the Location table are
+ designed for user use in doing Volume Management software.
+- Maximum Changer Wait, Maximum Open Wait, Maximum Rewind Wait to
+ accept time qualifiers.
+- Implement jobuid to replace old usage of job in keywords as
+ suggested by Eric Bollengier.
+- Apply patch for enhancing wait from Eric Bollengier. One can now:
+ wait (wait for all jobs to stop)
+ wait jobid=nn
+ wait jobuid=unique id
+ wait job=job-name
+- Implement write variables for Python to set Priority (anytime), and
+ Job Level, only during JobInit event.
+- Use the keyword ujobid to mean the unique job id; job or jobname
+ to mean the Job name given on the Name directive, and jobid to
+ be the numeric (non-unique) job id.
+- Allow the SD to use multiple drives during a backup/restore (only
+ one at a time). This is not well tested.
+- Integrate addition of line count limitation to bsmtp -l from
+ Sebastian Stark <stark at tuebingen.mpg.de>
+- Split the bacula start/start script into four files:
+ bacula -- starts and stops calling other scripts
+ bacula-ctl-dir -- starts/stops the director
+ bacula-ctl-fd -- starts/stops the File daemon
+ bacula-ctl-sd -- starts/stops the Storage daemon
+- Remove automatic case folding on Windows FDs. You must
+ explictly use the 'Ignore Case = yes' option.
+- Implement wild program in tools directory for testing
+ wild-cards. Almost identical to the regex program.
+- Use the new bregex.c to implement Regex expressions on Win32.
+- Apply patch from Christopher Hull
+ - Allow multiple connections to database with different
+ parameters.
+ - Invalidate the scheduler when doing a reload. Fixes seg
+ fault, but still 60 second window.
+ - Additional info in Reschedule message.
+ - Use set_jcr_job_status() everywhere to prevent loss of
+ cancel, error.
+ - Display peer IP in FD if error from connecting DIR.
+ - Don't increment file count for DIRBEGIN.
+ - Replace illegal characters in Win32 filename by _.
+ - Add SE_CREATE_PERMANENT_NAME privilege in Win32.
+ - Hash hard link filenames rather than linked list (performance).
+ - Fix for security failure in chdir on Win32.
+ - Add CreateDirectoryA/W win32 API entry points.
+- Add /silent option to Win32 FD for Install/Remove service.
+ programs to duplicate Bacula's base64 algorithm using standard
+ routines. This fixes bugs #296, and 565. Patch submitted by
+ author of bug #565.
+- Fixes to reloading the Dir conf file from Eric Bollengier and Christopher
+ Hull.
+- Modify LICENSE to correct some problems pointed out by Debian.
+ Implement patch submitted by cesarb in bug #606 to implement O_NOATIME
+ support.
+ O_NOATIME is a open() flag which makes it possible to read a file without
+ updating the inode atime (and also without the inode ctime update which
+ happens if you try to set the atime back to its previous value). It also
+ prevents a race condition when two programs are reading the same file, but
+ only one does not want to change the atime. It's most useful for backup
+ programs and file integrity checkers (and bacula can fit on both
+ categories).
+
+ Recent versions of the Linux kernel and glibc have support for it (the
+ glibc support being mostly copying the O_NOATIME definition to
+ bits/fcntl.h). If there's no support for it on the kernel, trying to use
+ it does nothing (since the kernel ignores unknown flags).
+
+ If the kernel has support for it, trying to use it either works, fails
+ silently (mostly in remote filesystems), or returns errno=EPERM (if you
+ are not either the owner of the file or root). A simple way to prevent the
+ failure is to open the file without the flag and set it later with
+ fcntl(F_SETFL), ignoring any EPERM errors.
+- Implement a pile of new man pages contributed by Jose Tallon.
+- Implement a number of user supplied patches for DVD writing.
+- Modify the database format for handling Migration jobs:
+ Add PriorJobId, RealEndTime to Job table
+ Delete MAC table
+ Remove Stripe from JobMedia record (not used, wasting space)
+ Add ScratchPoolId, RecyclePoolId, Enabled to Media record
+ Add Cost to Location table.
+ Enabled to Media table and Location table.
+- Security: harden authentication failure in FD by single threading errors
+ and forcing a 6 second wait.
+- If using GCC (actually g++) add the following compiler flags
+ -fno-strict-aliasing -fno-exceptions -fno-rtti
+- Turn on new bsnprintf() code. This could cause print output
+ to look different.
+- Implement job report that indicates where Storage and Pool
+ came from -- with overrides and Pool storage and NextPool,
+ it is all very complicated.
+- Add more detail (Storage, Device) to list of volumes printed
+ for restore.
+- Add new VOLMGMT message class. No messages are yet sent with this
+ class.
+- Add Catalog message destination in Messages resource that puts the
+ job report in the Log database table.
+- Spend a lot of time integrating mkcdrec with the rescue disk.
+- Add spooling/despooling info in status output of SD.
+- Add Comment field to llist of a volume.
+- Allow true/false in some yes/no questions.
+- Implement update volume enable=(on|off|true|false|archived|0|1|2)
+
+Additional Features Added for Win32:
+
+Added DriveType directive to the Director's Include Option FileSet
+resource. Allowed values are: fixed, removable, cdrom, and remote. There
+is only an implementation for Windows because it is the only platform that
+has the concept of drives.
+
+Adds EnhancedWild directive to the Director's Include Option FileSet
+resource. Allowed values are: yes and no.
+
+When EnhancedWild is enabled then the processing of the
+Wild, WildDir and WildFile is changed in the following ways.
+
+ Patterns conform to Posix
+ \ is not a special character in character classification []
+ To match a - it must be the first or last character
+ To match a ] it must be the first character
+
+ fnmatch option FNM_FILE_NAME is specified * doesn't match a /
+ so it won't match multiple directory levels in a path
+
+Relative WildFile patterns (ones without a leading /) match
+against the filename portion. This in combination with the
+FNM_FILE_NAME fnmatch() flag makes directives such as WildFile =
+abc*.def work as expected.
+
+Adds support for the shell's feature of brace expansion.
+
+Here is an example where braces allow 24 lines to be expressed in 5.
+
+# Exclude directories full of lots and lots of useless little files
+WildDir = "[A-Z]:/{Documents and
+Settings,{WINNT,Windows}/Profiles}/*/Cookies"
+WildDir = "[A-Z]:/{Documents and
+Settings,{WINNT,Windows}/Profiles}/*/Recent"
+WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local
+Settings,LOCALS~1}/History"
+WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local
+Settings,LOCALS~1}/Temp"
+WildDir = "[A-Z]:/{Documents and Settings,{WINNT,Windows}/Profiles}/*/{Local
+Settings,LOCALS~1}/Temporary Internet Files"
+
+
+
+Here are some hints if you want to play with the Windows Director and/or
+Storage daemon.
+
+Changer and Tape device names in Windows are Changer0, Changer1, etc and
+Tape0, Tape1, etc. If there isn't a device driver loaded for the Changer
+then you need to use the address <Port>:<Bus>:<Target>:<Lun>. Port is the
+SCSI Adapter Number, Bus is the Bus Number on the adapter (usually 0 since
+most adapters only have one bus), Target is the device's Target Device ID,
+Lun is the Logical Unit Number.
+
+You must specify DeviceType = tape in the Device resource in bacula-sd.conf
+since detection doesn't currently work.
