+- Check "update slots=7 scan storage=DLT drive=0" with
+ non-bacula tape in the drive.
+
+- --without-openssl breaks at least on Solaris.
+- 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)

+- Does ClientRunAfterJob fail the job on a bad return code?
+- Document cleaning up the spool files:
+ db, pid, state, bsr, mail, conmsg, spool
- Document the multiple-drive-changer.txt script.
-- On Win32 working directory must have drive letter ????
-- On Win32 working directory must be writable by SYSTEM to
- do restores.

+- Pruning with Admin job.
+- Does WildFile match against full name? Doc.
+For 1.39:
+- Add a new Autochanger directive "Global lock = yes|no"
+ that provides a global lock on calling mtx-changer so
+ that multiple autochanger definitions can reference
+ the same physical autochanger.
+- Look at -D_FORTIFY_SOURCE=2
+- Close STDOUT if debug_level == 0
+- Add recycle event.
+- Add scratch pool event.
+- Implement NeedVolume event
+- Add Win32 FileSet definition somewhere
+- Look at fixing restore status stats in SD.
+- Make selection of Database used in restore correspond to
+ client.
+- implement a mode that says when a hard read error is
+ encountered, read many times (as it currently does), and if the
+ block cannot be read, skip to the next block, and try again. If
+ that fails, skip to the next file and try again, ...
+- Add ACL to restore only to original location.
+- Add a recursive mark command (rmark) to restore.
+- "Minimum Job Interval = nnn" sets minimum interval between Jobs
+ of the same level and does not permit multiple simultaneous
+ running of that Job (i.e. lets any previous invocation finish
+ before doing Interval testing).
+- Look at simplifying File exclusions.
+- Fix store_yesno to be store_bitmask.
+- New directive "Delete purged Volumes"
+- new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
+ let it fill itself, and RecyclePoolId = XXX's PoolId so I can
+ see if it become stable and I just have to supervise
+ MyScratchPool
+- If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
+ PoolId, and when it is empty remove it.
+- Figure out how to recycle Scratch volumes back to the Scratch
+ Pool.
+- Add Volume=SCRTCH
+- 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. When jobs are running and bacula for some reason crashes or if I do a
+ restart it remembers and jobs it was running before it crashed or restarted
+ as of now I loose all jobs if I restart it.
+
+ 2. When spooling and in the midway if client is disconnected for instance a
+ laptop bacula completely discard the spool. It will be nice if it can write
+ that spool to tape so there will be some backups for that client if not all.
+
+ 3. We have around 150 clients machines it will be nice to have a option to
+ upgrade all the client machines bacula version automatically.
+
+ 4. Atleast one connection should be reserved for the bconsole so at heavy load
+ I should connect to the director via bconsole which at sometimes I can't
+
+ 5. Another most important feature that is missing, say at 10am I manually
+ started backup of client abc and it was a full backup since client abc has
+ no backup history and at 10.30am bacula again automatically started backup of
+ client abc as that was in the schedule. So now we have 2 multiple Full
+ backups of the same client and if we again try to start a full backup of
+ client backup abc bacula won't complain. That should be fixed.
+
+- Fix bpipe.c so that it does not modify results pointer.
+ ***FIXME*** calling sequence should be changed.
1.xx Major Projects:
#3 Migration (Move, Copy, Archive Jobs)
- (probably not this version)
#7 Single Job Writing to Multiple Storage Devices
- (probably not this version)
-
-For 1.39:
- Reserve blocks other restore jobs when first cannot connect
- to SD -- no way to cancel in SD if Dir job canceled.
-- Allow cancel of unknown Job
-- State not saved when closing Win32 FD by icon
+ 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
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.
+
=====
Regression tests:
- Finish TLS implementation.
- Port limiting -m in iptables to prevent DoS attacks
could cause broken pipes on Bacula.
+6. Build and test the Volume Shadow Copy (VSS) for Win32.
+- Allow cancel of unknown Job
+- State not saved when closing Win32 FD by icon
+- bsr-opt-test fails. bsr deleted. Fix.
+- Move Python daemon variables from Job to Bacula object.
+ WorkingDir, ConfigFile
+- Document that Bootstrap files can be written with cataloging
+ turned off.
+- Document details of ANSI/IBM labels
+- OS linux 2.4
+ 1) ADIC, DLT, FastStor 4000, 7*20GB
+- Linux Sony LIB-D81, AIT-3 library works.
+- 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:

+- Document Heartbeat Interval in the dealing with firewalls section.
+- Document new CDROM directory.
+- On Win32 working directory must have drive letter ????
+- On Win32 working directory must be writable by SYSTEM to
+ do restores.
+- Document that ChangerDevice is used for Alert command.
+- Add better documentation on how restores can be done
+8. Take one more try at making DVD writing work (no go)
+7. Write a bacula-web document
+- Why isn't the DEVICE structure defined when doing
+ a reservation?
+- Multi-drive changer seems to only use drive 0
+ Multiple drives don't seem to be opened.
+- My database is growing
+- Call GetLastError() in the berrno constructor rather
+ than delaying until strerror.
+- Tape xxx in drive 0, requested in drive 1
+- The mount command does not work with drives other than 0.
+- A mount should cause the SD to re-examine what Slot is
+ loaded.
+- The SD locks on to the first available drive then
+ wants a Volume that is released but in another drive --
+ chaos.
+- Run the regression scripts on Solaris and FreeBSD
+- Figure out how to package gui, and rescue programs.
+- Add a .dir command to restore tree code to eliminate the problem
