-VSS Thorsten Engel (in beta testing)
Version 1.37 Kern (see below)
========================================================
-1.37 Major Projects:
-#3 Migration (Move, Copy, Archive Jobs)
- (probably not this version)
-#7 Single Job Writing to Multiple Storage Devices
- (probably not this version)
-
-## Integrate web-bacula into a new Bacula project with
- bimagemgr.
-## Create a new GUI chapter explaining all the GUI programs.
+Final items for 1.37 before release:
+1. Fix bugs
+- Look at fixing restore status stats in SD.
-Autochangers:
-- 7. Implement new Console commands to allow offlining/reserving drives,
- and possibly manipulating the autochanger (much asked for).
-- Make "update slots" when pointing to Autochanger, remove
- all Volumes from other drives. "update slots all-drives"?
+- --without-openssl breaks at least on Solaris.
+- Figure out how to package gui, and rescue programs.
+- Test TLS.
+- Arno had to do -- to get update slots=x to work
+ UPDATE Media SET InChanger=0,Slot=0 WHERE InChanger>0 AND Slot>0; (MySQL)
Document:
-- Document that Bootstrap files can be written with cataloging
- turned off.
-- Pruning with Admin job.
-- Add better documentation on how restores can be done
-- OS linux 2.4
- 1) ADIC, DLT, FastStor 4000, 7*20GB
- 2) Sun, DDS, (Suns name unknown - Archive Python DDS drive), 1.2GB
- 3) Wangtek, QIC, 6525ES, 525MB (fixed block size 1k, block size etc.
- driver dependent - aic7xxx works, ncr53c8xx with problems)
- 4) HP, DDS-2, C1553A, 6*4GB
-- Doc the following
- to activate, check or disable the hardware compression feature on my
- exb-8900 i use the exabyte "MammothTool" you can get it here:
- http://www.exabyte.com/support/online/downloads/index.cfm
- There is a solaris version of this tool. With option -C 0 or 1 you can
- disable or activate compression. Start this tool without any options for
- a small reference.
-- Linux Sony LIB-D81, AIT-3 library works.
-- Document PostgreSQL performance problems bug 131.
-- Document testing
-- Document that ChangerDevice is used for Alert command.
-- Document new CDROM directory.
-- Document Heartbeat Interval in the dealing with firewalls section.
+- datadir for po files.
+- AM_GNU_GETTEXT finds the library if you specify
+ --with-libintl-prefix
+- Document cleaning up the spool files:
+ db, pid, state, bsr, mail, conmsg, spool
- Document the multiple-drive-changer.txt script.
-
-For 1.37:
-- Add # Job Level date to bsr file
-- Implement "PreferMountedVolumes = yes|no" in Job resource.
-=== rate design
- jcr->last_rate
- jcr->last_runtime
- MA = (last_MA * 3 + rate) / 4
- rate = (bytes - last_bytes) / (runtime - last_runtime)
-- Despool attributes simultaneously with data in a separate
- thread, rejoined at end of data spooling.
-- Implement Files/Bytes,... stats for restore job.
-- Implement Total Bytes Written, ... for restore job.
-- Add setting Volume State via Python.
-- Max Vols limit in Pool off by one?
-- Make bootstrap file handle multiple MediaTypes (SD)
-- Test restoring into a user restricted directory on Win32 -- see
- bug report.
-- --without-openssl breaks at least on Solaris.
+- Pruning with Admin job.
+- Restore of all files for a Job or set of jobs even if the file
+ records have been removed from the catalog.
+
+For 1.39:
+- Allow Check Labels to be used with Bacula labels.
+- "Resuming" a failed backup (lost line for example) by using the
+ failed backup as a sort of "base" job.
+- Look at NDMP
+- Email to the user when the tape is about to need changing x
+ days before it needs changing.
+- Command to show next tape that will be used for a job even
+ if the job is not scheduled.

+1.xx Major Projects:
+#3 Migration (Move, Copy, Archive Jobs)
+#7 Single Job Writing to Multiple Storage Devices
+- Reserve blocks other restore jobs when first cannot connect
+ to SD.
+- Add true/false to conf same as yes/no
+- For Windows disaster recovery see http://unattended.sf.net/
+- regardless of the retention period, Bacula will not prune the
+ last Full, Diff, or Inc File data until a month after the
+ retention period for the last Full backup that was done.
+- update volume=xxx --- add status=Full
+- Remove old spool files on startup.
+- Exclude SD spool/working directory.
+- Refuse to prune last valid Full backup. Same goes for Catalog.
- Python:
- Make a callback when Rerun failed levels is called.
- Give Python program access to Scheduled jobs.
+ - Add setting Volume State via Python.
- Python script to save with Python, not save, save with Bacula.
- Python script to do backup.
- What events?
- Change the Priority, Client, Storage, JobStatus (error)
at the start of a job.
- - Make sure that Python has access to Client address/port so that
- it can check if Clients are alive.
-
+- Why is SpoolDirectory = /home/bacula/spool; not reported
+ as an error when writing a DVD?
+- Make bootstrap file handle multiple MediaTypes (SD)
- Remove all old Device resource code in Dir and code to pass it
back in SD -- better, rework it to pass back device statistics.
- Check locking of resources -- be sure to lock devices where previously
resources were locked.
-- Add global lock on all devices when creating a device structure.
+- The last part is left in the spool dir.
-Maybe in 1.37:
-- Add start/end date editing in messages (%t %T, %e?) ...
-- Add ClientDefs similar to JobDefs.
-- Print more info when bextract -p accepts a bad block.
+
+- In restore don't compare byte count on a raw device -- directory
+ entry does not contain bytes.
- To mark files as deleted, run essentially a Verify to disk, and
when a file is found missing (MarkId != JobId), then create
a new File record with FileIndex == -1. This could be done
by the FD at the same time as the backup.

+ jcr->last_rate

+- Print more info when bextract -p accepts a bad block.
- Fix FD JobType to be set before RunBeforeJob in FD.
- Look at adding full Volume and Pool information to a Volume
label so that bscan can get *all* the info.
- Bug: if a job is manually scheduled to run later, it does not appear
in any status report and cannot be cancelled.
+==== Keeping track of deleted files ====
+ My "trick" for keeping track of deletions is the following.
+ Assuming the user turns on this option, after all the files
+ have been backed up, but before the job has terminated, the
+ FD will make a pass through all the files and send their
+ names to the DIR (*exactly* the same as what a Verify job
+ currently does). This will probably be done at the same
+ time the files are being sent to the SD avoiding a second
+ pass. The DIR will then compare that to what is stored in
+ the catalog. Any files in the catalog but not in what the
+ FD sent will receive a catalog File entry that indicates
+ that at that point in time the file was deleted.
+
+ During a restore, any file initially picked up by some
+ backup (Full, ...) then subsequently having a File entry
+ marked "delete" will be removed from the tree, so will not
+ be restored. If a file with the same name is later OK it
+ will be inserted in the tree -- this already happens. All
+ will be consistent except for possible changes during the
+ running of the FD.
+
+ Since I'm on the subject, some of you may be wondering what
+ the utility of the in memory tree is if you are going to
+ restore everything (at least it comes up from time to time
+ on the list). Well, it is still *very* useful because it
+ allows only the last item found for a particular filename
+ (full path) to be entered into the tree, and thus if a file
+ is backed up 10 times, only the last copy will be restored.
+ I recently (last Friday) restored a complete directory, and
+ the Full and all the Differential and Incremental backups
+ spanned 3 Volumes. The first Volume was not even mounted
+ because all the files had been updated and hence backed up
+ since the Full backup was made. In this case, the tree
+ saved me a *lot* of time.
+
+ Make sure this information is stored on the tape too so
+ that it can be restored directly from the tape.
+
+ Comments from Martin Simmons (I think they are all covered):
+ Ok, that should cover the basics. There are few issues though:
+
+ - Restore will depend on the catalog. I think it is better to include the
+ extra data in the backup as well, so it can be seen by bscan and bextract.
+
+ - I'm not sure if it will preserve multiple hard links to the same inode. Or
+ maybe adding or removing links will cause the data to be dumped again?
+
+ - I'm not sure if it will handle renamed directories. Possibly it will work
+ by dumping the whole tree under a renamed directory?
+
+ - It remains to be seen how the backup performance of the DIR's will be
+ affected when comparing the catalog for a large filesystem.
