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)
+ (probably not this version)
## Integrate web-bacula into a new Bacula project with
bimagemgr.
## Consider moving docs to their own project.
## Move rescue to its own project.
+## Create a new GUI chapter explaining all the GUI programs.
Autochangers:
- 3. Prevent two drives requesting the same Volume in any given
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"?
-

+Document:
+- 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.
+
For 1.37:
-- Make a callback when Rerun failed levels is called.
-- Give Python program access to Scheduled jobs.
-- Implement some way to turn off automatic pruning in Jobs.
-- Implement a way an Admin Job can prune, possibly multiple
- clients -- Python script?
-- Implement "NewVolumeEachJob = yes|no" in Dir.
-- FD Python
+- --without-openssl breaks at least on Solaris.
+- Python:
+ - Make a callback when Rerun failed levels is called.
+ - Give Python program access to Scheduled jobs.
- Python script to save with Python, not save, save with Bacula.
- Python script to do backup.
-- Create a new GUI chapter explaining all the GUI programs.
-- Look at Preben's acl.c error handling code.
-- Look at adding full Volume and Pool information to a Volume
- label so that bscan can get *all* the info.
+ - 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.
+
+- Implement "NewVolumeEachJob = yes|no" in Dir.
- Implement Maximum Job Spool Size
- Remove all old Device resource code in Dir and code to pass it
back in SD -- better, rework it to pass back device statistics.
-- Finish implementation of passing all Storage and Device needs to
- the SD.
- 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.
-- Make sure that Python has access to Client address/port so that
- it can check if Clients are alive.
-- Cleanup and complete Python scripting.
- - What events?
- - Change the Priority, Client, Storage, JobStatus (error)
- at the start of a job.
+- Fix the Rescue CDROM.
Maybe in 1.37:
+- Print more info when bextract -p accepts a bad block.
+- 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.
+- 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.
- If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
and there is only one volume in the pool, refuse to do it -- otherwise
he fills the Volume, then immediately starts reusing it.
- By the way: on page http://www.bacula.org/?page=tapedrives , at the
bottom, the link to "Tape Testing Chapter" is broken. It goes to
/html-manual/... while the others point to /rel-manual/...

- Restore restores all files, but then fails at the end trying

-- 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.
-- 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?
-- Tell the "restore" user when browsing is no longer possible.
- Require restore via the restore command or make a restore Job
get the bootstrap file.
- Make bootstrap file handle multiple MediaTypes (SD)
dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
askdir.c:219 NULL Volume name. This shouldn't happen!!!
3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
-
Label command failed for Volume DLT-20Dec04.
Do not forget to mount the drive!!!
- Bug: if a job is manually scheduled to run later, it does not appear
format string. Then I have the tape labeled automatically with weekday
name in the correct language.

+- Yes, that is surely the case. I probably should turn those into Warning
+ errors. In addition, you just made me think that it might not be bad to
+ add an option to check the file size after backing up the file and
+ report if it changes. This would be done as an option because it would
+ add extra overhead.
+
+ Kern, good idea. If you do do that, mention in the output: file
+ shrunk, or file expanded, just to make it obvious to the user
+ (without having to the refer to file size), just how the file size
+ changed.
+
+ Would this option be for all file, or just one file? Or a fileset?
- Make output from status use html table tags for nicely
presenting in a browser.
- Can one write tapes faster with 8192 byte block sizes?
bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
- Add regex from http://www.pcre.org to Bacula for Win32.
- Use only shell tools no make in CDROM package.
-- Document PostgreSQL performance problems bug 131.
-- Document testing
-- Document that ChangerDevice is used for Alert command.
- Include within include does it work?
- Implement a Pool of type Cleaning?
- Implement VolReadTime and VolWriteTime in SD
- Look at correcting the time jump in the scheduler for daylight
savings time changes.
- Add a "real" timer to network connections.
-- Write non-optimized bsrs from the JobMedia and Media records,
- even after Files are pruned.
- Promote to Full = Time period
- Despool attributes simultaneously with data in a separate
thread, rejoined at end of data spooling.

+- Use gather write() for network I/O.
+- Autorestart on crash.
- Add bandwidth limiting.
- Add acks every once and a while from the SD to keep
the line from timing out.

- If opening a tape in read/write mode fails attempt to open
it in read-only mode, and mark the tape for read only.
-- Add a read-only mode to the mount option.
- Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
with multiple priorities.
- If you use restore replace=never, the directory attributes for

- Add a "batch" mode to the Console (no unsolicited queries, ...).
- Add a .list all files in the restore tree (probably also a list all files)
Do both a long and short form.
- Look at adding SQL server and Exchange support for Windows.
- Each DVD-RAM disk would be a volume, just like each tape is

- Add disk seeking on restore; turn off seek on tapes.
