+ 22 February 2005
Major development:
Project Developer
======= =========
IPv6_2 Meno Abels
-Data encryption Meno Abels (see projects)
-Communication encryption Meno Abels
Version 1.37 Kern (see below)
========================================================
1.37 Major Projects:
#3 Migration (Move, Copy, Archive Jobs)
-#4 Embedded Python Scripting (implemented in Dir)
-#5 Events that call a Python program (Implemented in Dir)
+#4 Embedded Python Scripting
+ (Implemented in Dir/SD)
+#5 Events that call a Python program
+ (Implemented in Dir/SD)
#6 Select one from among Multiple Storage Devices for Job
#7 Single Job Writing to Multiple Storage Devices
- Optimized bootstrap.
For 1.37:
+- Device resource needs the "name" of the SD.
+- Add and option to see if the file size changed
+ during backup.
+- Implement "update device" from SD so that DIR will
+ always have current version of device.
+- Add disk seeking on restore.
+- Add Python writable variable for changing the Priority,
+ Client, Storage, JobStatus (error), ...
+- SD Autochanger work
+ - Lock all devices when using changer script.
+ - Check if Volume is mounted on another device
+ - Find a free drive if Changer name used.
+- SD Python
+ - Solicit Events
+- FD Python
+ - Python script to save with Python, not save, save with Bacula.
+ - Python script to do backup.
+- Windows restore:
+ data-fd: RestoreFiles.2004-12-07_15.56.42 Error:
+ > ..\findlib\../../findlib/create_file.c:275 Could not open e:/: ERR=Der
+ > Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen
+ > Prozess verwendet wird.
+ Restore restores all files, but then fails at the end.
+- Add better documentation on how restores can be done
+ from failed jobs.
+- Resolve the problem between Device name and Archive name,
+ and fix SD messages.
+- Make sure SD deletes spool files on error exit.
+- Delete old spool files when SD starts.
+- When Python creates a new label, the tape is immediately
+ recycled and no label created. This happens when using
+ autolabeling -- even when Python doesn't generate the name.
+- Add a restore directory-x
+- When labeling tapes, if you enter 000026, Bacula uses
+ the tape index rather than the Volume name 000026.
+- Max Vols limit in Pool off by one?
- Look at Preben's acl.c error handling code.
- See multiple-store.txt for Multiple Storage implementation
design.
-- Add Set Error from Python.
- Create a new GUI chapter explaining all the GUI programs.
- Tell the "restore" user when browsing is no longer possible.
-- Add disk seeking on restore.
- Cancel command should include JobId in list of Jobs.
- Require restore via the restore command or make a restore Job
get the bootstrap file.
-- Add dump of VolSessionId/Time and FileIndex with bls.
- Make bootstrap file handle multiple MediaTypes (SD)
-- Add offline command to Bacula console.
+- Add offline tape command to Bacula console.
- Add performance testing hooks
-- Add Python writable variable for changing the Priority.
- Document that Bootstrap files can be written with cataloging
turned off.
- Look at adding full Volume and Pool information to a Volume
1.37 Possibilities:
+=== From Carsten Menke <bootsy52@gmx.net>
+The bacula-devel list is CC'ed (I'm also subscribed to the list right now,
+so I will also get the responses).
+
+Following is a list of what I think in the situations where I'm faced with,
+could be a usefull enhancement to bacula, which I'm certain other users will
+benefit from as well.
+
+1. NextJob/NextJobs Directive within a Job Resource in the form of
+ NextJobs = job1,job2.
+
+ Why:
+ I currently solved the problem with running multiple jobs each after each
+ by setting the Max Wait Time for a job to 8 hours, and give
+ the jobs different Priorities. However, there scenarios where
+ 1 Job is directly depending on another job, so if the former job fails,
+ the job after it needn't to be run
+ while maybe other jobs should run despite of that
+
+Example:
+ A Backup Job and a Verify job, if the backup job fails there is no need to run
+ the verify job, as the backup job already failed. However, one may like
+ to backup the Catalog to disk despite of that the main backup job failed.
+
+Notes:
+ I see that this is related to the Event Handlers which are on the ToDo
+ list, also it is maybe a good idea to check for the return value and
+ execute different actions based on the return value
+
+2. Priorities also for the Schedule Resource
+
+ Why:
+
+ With this it is possible to run monthly jobs at the end of the month
+ instead of the beginning of the next month, so one could define
+ weekly and monthly pools to be run on Fridays and if there are
+ 2 Jobs resulting on the same time, the one with the higher priority
+ takes precedence. This is also helpfull to implement a daily
+ rotation scheme with an additional 2 weeks changing weekly pool
+
+Example:
+ Schedule {
+ Name = "NightlyBackup"
+ Run = Priority = 1,Pool=Weekly friday at 21:00
+ Run = Priority = 2,Pool=Weekly monthly on friday at 21:00
+ Run = Priority = 3,Pool=Weekly yearly on friday at 21:00
+ }
+
+3. offline capability to bconsole
+
+ Why:
+ Currently I use a script which I execute within the last Job via the
+ RunAfterJob Directive, to release and eject the tape.
+ So I have to call bconsole "release=Storage-Name" and afterwards
+ mt -f /dev/nst0 eject to get the tape out.
+
+ If I have multiple Storage Devices, than these may not be /dev/nst0 and
+ I have to modify the script or call it with parameters etc.
+ This would actually not be needed, as everything is already defined
+ in bacula-sd.conf and if I can invoke bconsole with the
+ storage name via $1 in the script than I'm done and information is
+ not duplicated.
+
+4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
+
+ Why:
+
+ For the reason mentioned in 3. to have the ability to call a
+ script with /scripts/foobar %s and in the script use $1
+ to pass the Storage Name to bconsole
+
+5. Setting Volume State within a Job Resource
+
+ Why:
+ Instead of using "Maximum Volume Jobs" in the Pool Resource,
+ I would have the possibilty to define
+ in a Job Resource that after this certain job is run, the Volume State
+ should be set to "Volume State = Used", this give more flexibility (IMHO).
+
+6. Localization of Bacula Messages
+
+ Why:
+ Unfortunatley many,many people I work with don't speak english very well.
+ So if at least the Reporting messages would be localized then they
+ would understand that they have to change the tape,etc. etc.
+
+ I volunteer to do the german translations, and if I can convince my wife also
+ french and Morre (western african language).
+
+7. OK, this is evil, probably bound to security risks and maybe not possible
+ due to the design of bacula.
+
+ Implementation of Backtics ( `command` ) for shell comand execution to
+ the "Label Format" Directive.
+
+Why:
+
+ Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
+ Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
+ use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
+ the localized name for the day of the week appended to the
+ format string. Then I have the tape labeled automatically with weekday
+ name in the correct language.
+==========
- Can one write tapes faster with 8192 byte block sizes?
- Specify a single directory to restore.
- Implement Maximum Job Spool Size
- any actions should be interuptable with STRG+C
- command-expansion would be pretty cool
====
+- When the replace Never option is set, new directory permissions
+ are not restored. See bug 213. To fix this requires creating a
+ list of newly restored directories so that those directory
+ permissions *can* be restored.
- Compaction of Disk space by "migrating" Volumes that have pruned
Jobs (what criteria? size, #jobs, time).
- Add prune all command
- Implement Preben's suggestion to add
File System Types = ext2, ext3
to FileSets, thus simplifying backup of *all* local partitions.
+- Try to open a device on each Job if it was not opened
+ when the SD started.
+- Add dump of VolSessionId/Time and FileIndex with bls.
