-#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.
-
-Autochangers:
-- 3. Prevent two drives requesting the same Volume in any given
- autochanger, by checking if a Volume is mounted on another drive
- in an Autochanger.
-- 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"?
Document:
-- Document that Bootstrap files can be written with cataloging
- turned off.

+- Does WildFile match against full name? Doc.
+- %d and %v only valid on Director, not for ClientRunBefore/After.
+
+Priority:
+- Implement a way to disable a drive (so you can use the second
+ drive of an autochanger, and the first one will not be used or
+ even defined).
+- Implement code that makes the Dir aware that a drive is an
+ autochanger (so the user doesn't need to use the Autochanger = yes
+ directive).
+
+For 1.39:
+- Make hardlink code at line 240 of find_one.c use binary search.
+- Queue warning/error messages during restore so that they
+ are reported at the end of the report rather than being
+ hidden in the file listing ...
+- Fix Maximum Changer Wait (and others) to accept qualifiers.
+- Look at -D_FORTIFY_SOURCE=2
+- 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 level table:
+ create table LevelType (LevelType binary(1), LevelTypeLong tinyblob);
+ insert into LevelType (LevelType,LevelTypeLong) values
+ ("F","Full"),
+ ("D","Diff"),
+ ("I","Inc");
+- 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.

+- From: Arunav Mandal <amandal@trolltech.com>
+ 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)
+#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 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.
+=== rate design
+ jcr->last_rate
+ jcr->last_runtime
+ MA = (last_MA * 3 + rate) / 4
+ rate = (bytes - last_bytes) / (runtime - last_runtime)
+- Max Vols limit in Pool off by one?
+- Implement Files/Bytes,... stats for restore job.
+- Implement Total Bytes Written, ... for restore job.
+- Despool attributes simultaneously with data in a separate
+ thread, rejoined at end of data spooling.
+- 7. Implement new Console commands to allow offlining/reserving drives,
+ and possibly manipulating the autochanger (much asked for).
+- 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.
- 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.
-Regression tests (Scott):
+==== 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.
+
+=====
+
+Regression tests:
- Add Pool/Storage override regression test.
- Add delete JobId to regression.
- Add a regression test for dbcheck.
=== Done
-- Save mount point for directories not traversed with onefs=yes.
-- Add seconds to start and end times in the Job report output.
-- if 2 concurrent backups are attempted on the same tape
- drive (autoloader) into different tape pools, one of them will exit
- fatally instead of halting until the drive is idle
-- Update StartTime if job held in Job Queue.
-- Look at www.nu2.nu/pebuilder as a helper for full windows
- bare metal restore. (done by Scott)
-- Fix orphanned buffers:
- Orphaned buffer: 24 bytes allocated at line 808 of rufus-dir job.c
- Orphaned buffer: 40 bytes allocated at line 45 of rufus-dir alist.c
-- 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.
-- If Bacula does not find the right tape in the Autochanger,
- then mark the tape in error and move on rather than asking
- for operator intervention.
-- Cancel command should include JobId in list of Jobs.
-- Add performance testing hooks
-- Bootstrap from JobMedia records.
-- Implement WildFile and WildDir to solve problem of
- saving only *.doc files.
-- Fix
- Please use the "label" command to create a new Volume for:
- Storage: DDS-4-changer
- Media type:
- Pool: Default
- label
- The defined Storage resources are:
-- Copy Changer Device and Changer Command from Autochanger
- to Device resource in SD if none given in Device resource.
-- 1. Automatic use of more than one drive in an autochanger (done)
-- 2. Automatic selection of the correct drive for each Job (i.e.
- selects a drive with an appropriate Volume for the Job) (done)
-- 6. Allow multiple simultaneous Jobs referencing the same pool write
- to several tapes (some new directive(s) are are probably needed for
- this) (done)
-- Locking (done)
-- Key on Storage rather than Pool (done)
-- Allow multiple drives to use same Pool (change jobq.c DIR) (done).
-- Synchronize multiple drives so that not more
- than one loads a tape and any time (done)
-- 4. Use Changer Device and Changer Command specified in the
- Autochanger resource, if none is found in the Device resource.
- You can continue to specify them in the Device resource if you want
- or need them to be different for each device.
-- 5. Implement a new Device directive (perhaps "Autoselect = yes/no")
- that can allow a Device be part of an Autochanger, and hence the changer
- script protected, but if set to no, will prevent the Device from being
- automatically selected from the changer. This allows the device to
- be directly accessed through its Device name, but not through the
- AutoChanger name.
-#6 Select one from among Multiple Storage Devices for Job
-#5 Events that call a Python program
- (Implemented in Dir/SD)
-- Make sure the Device name is in the Query packet returned.
-- Don't start a second file job if one is already running.
-- Implement EOF/EOV labels for ANSI labels
-- Implement IBM labels.
-- 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.
-- Scratch Pool where the volumes can be re-assigned to any Pool.
-- 28-Mar 23:19 rufus-sd: acquire.c:379 Device "DDS-4" (/dev/nst0)
- is busy reading. Job 6 canceled.
-- Remove separate thread for opening devices in SD. On the other
- hand, don't block waiting for open() for devices.
-- Fix code to either handle updating NumVol or to calculate it in
- Dir next_vol.c
-- Ensure that you cannot exclude a directory or a file explicitly
- Included with File.
-#4 Embedded Python Scripting
- (Implemented in Dir/SD/FD)
-- Add Python writable variable for changing the Priority,
- Client, Storage, JobStatus (error), ...
-- SD Python
- - Solicit Events
-- Add disk seeking on restore; turn off seek on tapes.
- stored/match_bsr.c
-- Look at dird_conf.c:1000: warning: `int size'
- might be used uninitialized in this function
-- Indicate when a Job is purged/pruned during restore.
-- Implement some way to turn off automatic pruning in Jobs.
-- Implement a way an Admin Job can prune, possibly multiple
- clients -- Python script?
-- Look at Preben's acl.c error handling code.
-- SD crashes after a tape restore then doing a backup.
-- If drive is opened read/write, close it and re-open
- read-only if doing a restore, and vice-versa.
-- 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 trying
- to set the attributes of e:
- from failed jobs.- Resolve the problem between Device name and Archive name,
- and fix SD messages.
-- Tell the "restore" user when browsing is no longer possible.
-- Add a restore directory-x
-- Write non-optimized bsrs from the JobMedia and Media records,
- even after Files are pruned.
-- Delete Stripe and Copy from VolParams to save space.
-- Fix option 2 of restore -- list where file is backed up -- require Client,
- then list last 20 backups.
-- Finish implementation of passing all Storage and Device needs to
- the SD.
-- Move test for max wait time exceeded in job.c up -- Peter's idea.
-## Consider moving docs to their own project.
-## Move rescue to its own project.
-- Add client version to the Client name line that prints in
- the Job report.
-- Fix the Rescue CDROM.
-- 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/...
-- Device resource needs the "name" of the SD.
-- Specify a single directory to restore.
-- Implement MediaType keyword in bsr?
-- Add a date and time stamp at the beginning of every line in the
- Job report (Volker Sauer).
-- Add level to estimate command.
-- Add "limit=n" for "list jobs"
-- Make bootstrap filename unique.
-- Make Dmsg look at global before calling subroutine.
-- From Chris Hull:
- it seems to be complaining about 12:00pm which should be a valid 12
- hour time. I changed the time to 11:59am and everything works fine.
- Also 12:00am works fine. 0:00pm also works (which I don't think
- should). None of the values 12:00pm - 12:59pm work for that matter.
-- Require restore via the restore command or make a restore Job
- get the bootstrap file.
-- Implement Maximum Job Spool Size
-- Fix 3993 error in SD. It forgets to look at autochanger
- resource for device command, ...
