- Release Notes for Bacula 1.33.4
-
- Bacula code: Total files = 306 Total lines = 90,715 (*.h *.c *.in)
-
-Major Features:
-- Data spooling which eliminates tape shoe-shine during Inc backups,
- and permits multiple simultaneous backups without interleaved blocks.
-- Native Win32 client -- much faster and restores permissions correctly
- (thanks to Christopher Hull)
-- PostgreSQL database driver (thanks to Dan Langille).
-- Polling of devices eliminating need to unmount and mount from
- console.
-- Improved Autochange support of Slots (update slots scan).
-- Autochanger support for multiple drives.
-- New conio code to implement Console command line editing and history.
-- JobDefs resource permits smaller .conf files for Director
-- Access console lists for the Console
-- Pool level overrides.
-- Daemon statistics memory.
-- Improved btape "test" and "fill" commands.
-
-
-Items to note: !!!!!
-- The restore default is changed to have nothing selected by default.
- You must either enter: "restore all" or after getting into the tree
- selection prompt enter "mark *" to have everything selected.
-- In previous versions the "all" keyword on the restore command caused
- it to return without user interaction after selecting everything.
- This function is now replaced by the "done" keyword (more logical).
- The "all" keyword now causes everything to be selected by default.
-- The default tape driver behavior is now to write only a single EOF
- at the end of the tape. For most tape drives, this is totally
- transparent and nothing needs to be done. For FreeBSD see below.
-- FreeBSD users NOTE!!!!!
- You MUST add the following two records to your SD Device resource for
- tape drives.
-
- TWOEOF = yes
- Fast Forward Space File = no
-
-- The daemon protocol has changed, you must update everything at once.
-- The database level has been updated. You must either re-initialize
- your databases with:
-
- ./drop_bacula_tables
- ./make_bacula_tables
-
- which will delete ALL prior catalog information, or you can
- update your database with:
-
- ./update_bacula_tables
-
- Please save your old database before dropping the tables or doing
- an upgrade or you may regret it later.
-
-- smtp has now become bsmtp -- you *must* modify your .conf files.
-- console has now become bconsole.
-- console.conf is now bconsole.conf
-- Please don't underestimate the repercussions of the bsmtp and bconsole
- name changes!
-
-
-New directives:
-- "Close on Poll = yes/no" in SD Device resource.
-- "Volume Poll Interval = time-interval" in SD Device resource.
-- "Two EOF = yes/no" in SD Device resource.
-- "Maximum Network Buffer Size = size" in SD Device resource.
-- "Maximum Network Buffer Size = size" in FD FileDaemon (or Client) resource.
-- "Console" new resource in Director conf file.
- New directives: Name, Description, Password, JobACL, ClientACL,
- StorageACL, ScheduleACL, RunACL, PoolACL, CommandACL,
- FileSetACL, CatalogACL.
-- "Max Run Time = duration" in Director Job resource.
-- "Max Wait Time = duration" in Director Job resource (not fully implemented).
-- "JobDefs = name-of-resource" in Director Job resource.
-- "Jobdefs" new resource in Director. Same directives as for a Job.
-- "Full Backup Pool = xxx" in Job resource in the Director.
-- "Incremental Backup Pool = xxx" in Job resource in the Director.
-- "Differential Backup Pool = xxx" in Job resource in the Director.
-- Three new options on the Run override statement in a Schedule resource:
- FullPool=xxx
- IncrementalPool=xxx
- DifferentialPool=xxx
-- SpoolData=yes/no in DIR Job resource
-- SpoolData=yes/no in Run override directive.
-- MaximumSpoolSize in SD Device resource
-- MaximumSpoolJobSize in SD Device resource
-- SpoolDirectory in SD Device resource.
+ Release Notes for Bacula 1.37.6
+
+ Bacula code: Total files = 414 Total lines = 123,723 (*.h *.c *.in)
+
+
+Major Changes:
+- 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.
+- Preliminary 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.
+
+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:
-- "SetIP"
-- Added "pool=xxx" to restore command line.
-- Added "fileset=xxx" to restore command line.
-- Fixed "storage=xxx" on restore command line.
-- "markdir" command in restore tree.
-- "unmarkdir" command in restore tree.
-- "quit" command in restore tree.
-- Trace option on "setdebug trace=1/0 ..."
-- Update slots scan
-- The "all" keyword on the restore command marks all files by default.
-- The "done" keyword prevents user interaction with the tree -- used
- mostly for batch scripting.
-
-
-Additional changes:
-- Implement Gnome 2.0 restore GUI
-- Add a missing unlock in the jobq handler.
-- Fix bug where a soft linked file and a directory had the same name
- by treating the soft link as a directory and putting the entries under
- it. This fixes the bug reported by Alexander Mueller.
-- Apply Jess Guardiani's second fix to list autochanger volumes without
- opening the drive (necessary on FreeBSD if no tape is in the drive).
-- Reworked the command line handler in restore to walk through the
- arguments one at a time. This makes the file= entries work correctly.
- Also reworked the code that takes the MediaType and finds a
- storage device.
-- Add quit command to restore tree handler.
-- Make restore tree handler remember if a hard link is present, and
- in doing a mark, only get database entry if there is a hard link.
- mark commands thus run at least 2 orders of magnitude faster.
-- Add files=xxx field to run command submitted for restore.
-- Add yes to restore run command if either yes or run is command line
- argument.
-- Make "yes" on command line argument skip prompt for modification of
- run job.
-- Add markdir and unmarkdir -- both affect only the directory in
- question and do not do a recursive descent.
-- Make tree command automatically mark all higher level directories to
- be restored when a directory or a file is selected. Such directories
- are indicated by preceding the name with a + to indicate that only
- the directory entry is selected and not the whole directory tree.
-- Modify a few tree commands to walk through all arguments rather than
- just taking the first one.
-- Improved btape "test" and "fill" commands.
-- The ability to ask the Storage daemon on a device by device basis
- to "poll" the tape drive at a given interval (minimum 1 minute). If
- a tape is found, its label is read and if appropriate it is used.
- This eliminates the need to do "mount" commands.
-- The ability to close and re-open the device when a poll occurs.
- This permits dealing with certain recalcitrant autochangers that
- invalidate devices (typically on FreeBSD).
-- Dan Langille has written a PostgreSQL driver for Bacula.
-- Implement "update slots scan" that reads the volume label(s).
-- The full form of the scan is "scan=1,2,4-5,7". With no specification,
- all occupied slots are scanned.
-- Turn off changer Volumes that are not current in the changer when
- an "update slots" is done, or if any tape operation discovers that
- the right volume is not in the slot.
-- The console program will run all commands it finds in ~/.bconsolerc
- at startup.
-- Add Dan Langille's changes to the bacula start/stop script that
- permit dropping root permissions just after startup.
-- New version 1.5.5-1 Cygwin.
-- Modify SD to update the catalog database when it is shutdown,
- even if the job is canceled.
-- Fixed seg fault in restore of multiple simultaneous jobs to
- a single Volume.
-- Fixed thread race problem in multiple simultaneous jobs to
- a single Volume where the volume label is not in the first
- tape block, so the tape is not recognized.
-- Restore directory tree automatically selects all higher level
- directories to be restored.
-- Implement conio.c to use in console program -- mini-readline.
-- Enhance "fill" command of btape -- simpler output. Use -v to
- cause last block to be dumped after write and after re-read.
-- Added an autochanger test to the btape "test" command. It is
- automatically invoked if the autochanger is properly configured. It
- is still a bit primitive but covers the essential of testing
- the mtx-changer script with your autochanger.
-- Select the oldest LastWritten volume during recycling.
-- Added forward space file test to btape "test" command.
-- All 1.32d patches applied.
-- Fixed seg fault in restore of multiple simultaneous jobs to
- a single Volume.
-- Fixed thread race problem in multiple simultaneous jobs to
- a single Volume where the volume lable is not in the first
- tape block, so the tape is not recognized.
+- "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".
+- 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 j. This
+ argument *must* be passed unchanged to 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:
+
+ bacula.get(j, "Variable-name")
+
+ where j 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:
+
+ bacula.set(jcr=j, VolumeName="xyz")
+
+ The two currently implemented writable "variables" are:
+
+ VolumeName and JobReport
+
+ It is possible to submit a Bacula run command with the following:
+
+ bacula.run(j, "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(j):
+ jobid = bacula.get(j, "JobId")
+ client = bacula.get(j, "Client")
+ bacula.set(jcr=j, JobReport="EndJob output: JobId=%d Client=%s.\n" % (jobid, client))
+ if (jobid < 5) :
+ startid = bacula.run(j, "run kernsave")
+ print "Python started jobid=", startid
+
+ return 1
+====
+
+== File NewVolume.py ===
+import bacula
+
+def NewVolume(j):
+ jobid = bacula.get(j, "JobId")
+ print "JobId=", jobid
+ client = bacula.get(j, "Client")
+ print "Client=" + client
+ numvol = bacula.get(j, "NumVols");
+ print "NumVols=", numvol
+ bacula.set(jcr=j, JobReport="New Volume set for Job.\n")
+ bacula.set(jcr=j, VolumeName="TestA-001")
+ return 1
