Kern's ToDo List
- 22 February 2006
+ 087 June 2007
-Major development:
-Project Developer
-======= =========
Document:
+- !!! Cannot restore two jobs a the same time that were
+ written simultaneously unless they were totally spooled.
- Document cleaning up the spool files:
db, pid, state, bsr, mail, conmsg, spool
- Document the multiple-drive-changer.txt script.
- Pruning with Admin job.
- Does WildFile match against full name? Doc.
- %d and %v only valid on Director, not for ClientRunBefore/After.
+- During tests with the 260 char fix code, I found one problem:
+ if the system "sees" a long path once, it seems to forget it's
+ working drive (e.g. c:\), which will lead to a problem during
+ the next job (create bootstrap file will fail). Here is the
+ workaround: specify absolute working and pid directory in
+ bacula-fd.conf (e.g. c:\bacula\working instead of
+ \bacula\working).
+- Document techniques for restoring large numbers of files.
+- Document setting my.cnf to big file usage.
+- Add example of proper index output to doc. show index from File;
+- Correct the Include syntax in the m4.xxx files in examples/conf
+- Document JobStatus and Termination codes.
+- Fix the error with the "DVI file can't be opened" while
+ building the French PDF.
+- Document more DVD stuff
+- Doc
+ { "JobErrors", "i"},
+ { "JobFiles", "i"},
+ { "SDJobFiles", "i"},
+ { "SDErrors", "i"},
+ { "FDJobStatus","s"},
+ { "SDJobStatus","s"},
+- Document all the little details of setting up certificates for
+ the Bacula data encryption code.
+- Document more precisely how to use master keys -- especially
+ for disaster recovery.
+
+Professional Needs:
+- Migration from other vendors
+ - Date change
+ - Path change
+- Filesystem types
+- Backup conf/exe (all daemons)
+- Backup up system state
+- Detect state change of system (verify)
+- Synthetic Full, Diff, Inc (Virtual, Reconstructed)
+- SD to SD
+- Modules for Databases, Exchange, ...
+- Novell NSS backup http://www.novell.com/coolsolutions/tools/18952.html
+- Compliance norms that compare restored code hash code.
+- When glibc crash, get address with
+ info symbol 0x809780c
+- How to sync remote offices.
+- Exchange backup:
+ http://www.microsoft.com/technet/itshowcase/content/exchbkup.mspx
Priority:
-
-For 1.39:
+- Make restore use the in-use volume reservation algorithm.
+- Look at mincore: http://insights.oetiker.ch/linux/fadvise.html
+- Unicode input http://en.wikipedia.org/wiki/Byte_Order_Mark
+- How does restore JobId=nnn work? (Dirk)
+- What does: restore select fileset="TestSet" client="workplay-fd" pool="Default"
+> storage="File2" before="2007-02-05 23:05:04" do? (Dirk)
+
+- Implement update jobid=
+- Mention Eric and Marc's work + Marc's doc.
+- Add TLS to bat
+- When Pool specifies Storage command override does not work.
+- Implement wait_for_sysop() message display in wait_for_device(), which
+ now prints warnings too often.
+
+- Ensure that each device in an Autochanger has a different
+ Device Index.
+- Add Catalog = to Pool resource so that pools will exist
+ in only one catalog -- currently Pools are "global".
+- Look at sg_logs -a /dev/sg0 for getting soft errors.
+- btape "test" command with Offline on Unmount = yes
+
+ This test is essential to Bacula.
+
+ I'm going to write one record in file 0,
+ two records in file 1,
+ and three records in file 2
+
+ 02-Feb 11:00 btape: ABORTING due to ERROR in dev.c:715
+ dev.c:714 Bad call to rewind. Device "LTO" (/dev/nst0) not open
+ 02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
+ Kaboom! btape, btape got signal 11. Attempting traceback.
+
+- Encryption -- email from Landon
+ > The backup encryption algorithm is currently not configurable, and is
+ > set to AES_128_CBC in src/filed/backup.c. The encryption code
+ > supports a number of different ciphers (as well as adding arbitrary
+ > new ones) -- only a small bit of code would be required to map a
+ > configuration string value to a CRYPTO_CIPHER_* value, if anyone is
+ > interested in implementing this functionality.
+
+- Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
+ does the right thing.
+- Why doesn't @"xxx abc" work in a conf file?
+- Figure out some way to "automatically" backup conf changes.
+- Add the OS version back to the Win32 client info.
+- Restarted jobs have a NULL in the from field.
+- Modify SD status command to indicate when the SD is writing
+ to a DVD (the device is not open -- see bug #732).
+- Look at the possibility of adding "SET NAMES UTF8" for MySQL,
+ and possibly changing the blobs into varchar.
+- Ensure that the SD re-reads the Media record if the JobFiles
+ does not match -- it may have been updated by another job.
+- Look at moving the Storage directive from the Job to the
+ Pool in the default conf files.
+- Doc items
+- Test Volume compatibility between machine architectures
+- Encryption documentation
+- Wrong jobbytes with query 12 (todo)
+- bacula-1.38.2-ssl.patch
+- Bare-metal recovery Windows (todo)
+
+
+Projects:
+- Average tape size from Eric
+ SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
+ count(Media.MediaId) AS volnum,
+ sum(Media.VolBytes) AS voltotal,
+ Media.PoolId AS PoolId,
+ Media.MediaType AS MediaType
+ FROM Media
+ LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
+ Media.MediaType AS MediaType
+ FROM Media
+ WHERE Media.VolStatus = 'Full'
+ GROUP BY Media.MediaType
+ ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
+ GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
+- GUI
+ - Admin
+ - Management reports
+ - Add doc for bweb -- especially Installation
+ - Look at Webmin
+ http://www.orangecrate.com/modules.php?name=News&file=article&sid=501
+- Performance
+ - FD-SD quick disconnect
+ - Despool attributes in separate thread
+ - Database speedups
+ - Embedded MySQL
+ - Check why restore repeatedly sends Rechdrs between
+ each data chunk -- according to James Harper 9Jan07.
+ - Building the in memory restore tree is slow.
+- Features
+ - Better scheduling
+ - Full at least once a month, ...
+ - Cancel Inc if Diff/Full running
+ - More intelligent re-run
+ - New/deleted file backup
+ - FD plugins
+ - Incremental backup -- rsync, Stow
+
+
+For next release:
+- Look at mondo/mindi
+- Don't restore Solaris Door files:
+ #define S_IFDOOR in st_mode.
+ see: http://docs.sun.com/app/docs/doc/816-5173/6mbb8ae23?a=view#indexterm-360
+- Make Bacula by default not backup tmpfs, procfs, sysfs, ...
+- Fix hardlinked immutable files when linking a second file, the
+ immutable flag must be removed prior to trying to link it.
+- Implement Python event for backing up/restoring a file.
+- Change dbcheck to tell users to use native tools for fixing
+ broken databases, and to ensure they have the proper indexes.
+- add udev rules for Bacula devices.
+- If a job terminates, the DIR connection can close before the
+ Volume info is updated, leaving the File count wrong.
+- Look at why SIGPIPE during connection can cause seg fault in
+ writing the daemon message, when Dir dropped to bacula:bacula
+- Look at zlib 32 => 64 problems.
+- Possibly turn on St. Bernard code.
+- Fix bextract to restore ACLs, or better yet, use common routines.
+- Do we migrate appendable Volumes?
+- Remove queue.c code.
- Print warning message if LANG environment variable does not specify
UTF-8.
+- New dot commands from Arno.
+ .show device=xxx lists information from one storage device, including
+ devices (I'm not even sure that information exists in the DIR...)
+ .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
+ better machine-readable output like "Ok" or "Error busy"
+ .move eject device=xxx toslot=yyy the same as above, but with a new
+ target slot. The catalog should be updated accordingly.
+ .move transfer device=xxx fromslot=yyy toslot=zzz

+
+- Possibly allow SD to spool even if a tape is not mounted.
+- It appears to me that you have run into some sort of race
+ condition where two threads want to use the same Volume and they
+ were both given access. Normally that is no problem. However,
+ one thread wanted the particular Volume in drive 0, but it was
+ loaded into drive 1 so it decided to unload it from drive 1 and
+ then loaded it into drive 0, while the second thread went on
+ thinking that the Volume could be used in drive 1 not realizing
+ that in between time, it was loaded in drive 0.
+ I'll look at the code to see if there is some way we can avoid
+ this kind of problem. Probably the best solution is to make the
+ first thread simply start using the Volume in drive 1 rather than
+ transferring it to drive 0.
+- Fix re-read of last block to check if job has actually written
+ a block, and check if block was written by a different job
+ (i.e. multiple simultaneous jobs writing).
+- Figure out how to configure query.sql. Suggestion to use m4:
+ == changequote.m4 ===
+ changequote(`[',`]')dnl
+ ==== query.sql.in ===
+ :List next 20 volumes to expire
+ SELECT
+ Pool.Name AS PoolName,
+ Media.VolumeName,
+ Media.VolStatus,
+ Media.MediaType,
+ ifdef([MySQL],
+ [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
+ ifdef([PostgreSQL],
+ [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
+ Media.LastWritten
+ FROM Pool
+ LEFT JOIN Media
+ ON Media.PoolId=Pool.PoolId
+ WHERE Media.LastWritten>0
+ ORDER BY Expire
+ LIMIT 20;
+ ====
+ Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
+
+ The problem is that it requires m4, which is not present on all machines
+ at ./configure time.
+- Given all the problems with FIFOs, I think the solution is to do something a
+ little different, though I will look at the code and see if there is not some
+ simple solution (i.e. some bug that was introduced). What might be a better
+ solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
+ write data to a program rather than the FIFO. For example, suppose you
+ create a FIFO named:
+
+ /home/kern/my-fifo
+
+ Then, I could imagine if you backup and restore this file with a direct
+ reference as is currently done for fifos, instead, during backup Bacula will
+ execute:
+
+ /home/kern/my-fifo.backup
+
+ and read the data that my-fifo.backup writes to stdout. For restore, Bacula
+ will execute:
+
+ /home/kern/my-fifo.restore
+
+ and send the data backed up to stdout. These programs can either be an
+ executable or a shell script and they need only read/write to stdin/stdout.
+
+ I think this would give a lot of flexibility to the user without making any
+ significant changes to Bacula.
+
+
+==== SQL
+# get null file
+select FilenameId from Filename where Name='';
+# Get list of all directories referenced in a Backup.
+select Path.Path from Path,File where File.JobId=nnn and
+ File.FilenameId=(FilenameId-from-above) and File.PathId=Path.PathId
+ order by Path.Path ASC;
+

=== Migration from David ===
What I'd like to see:
Here's how I'd define Migration Selection Types:
+With Regexes:
+Client -- Migrate data from selected client only. Migration Selection
+Pattern regexp provides pattern to select client names, eg ^FS00* makes
+all client names starting with FS00 eligible for migration.
+
+Jobname -- Migration all jobs matching name. Migration Selection Pattern
+regexp provides pattern to select jobnames existing in pool.
+
+Volume -- Migrate all data on specified volumes. Migration Selection
+Pattern regexp provides selection criteria for volumes to be migrated.
+Volumes must exist in pool to be eligible for migration.
+
+
+With Regex optional:
LowestUtil -- Identify the volume in the pool with the least data on it
and empty it. No Migration Selection Pattern required.
<lowmig>. Pool highmig and lowmig values are in pool definition, no
Migration Selection Pattern required.
-Client -- Migrate data from selected client only. Migration Selection
-Pattern regexp provides pattern to select client names, eg ^FS00* makes
-all client names starting with FS00 eligible for migration.
+
+No regex:
+SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
+Migration Selection Pattern contains SQL query to execute; should return
+a list of 1 or more jobuids to migrate.
PoolResidence -- Migrate data sitting in pool for longer than
PoolResidence value in pool definition. Migration Selection Pattern
optional; if specified, override value in pool definition (value in
minutes).
-Volume -- Migrate all data on specified volumes. Migration Selection
-Pattern regexp provides selection criteria for volumes to be migrated.
-Volumes must exist in pool to be eligible for migration.
-
-Jobname -- Migration all jobs matching name. Migration Selection Pattern
-regexp provides pattern to select jobnames existing in pool.
-
-SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
-Migration Selection Pattern contains SQL query to execute; should return
-a list of 1 or more jobuids to migrate.

+- 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.
+
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
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.
+ that at that point in time the file was deleted. This
+ either transmitted to the FD or simultaneously computed in
+ the FD, so that the FD can put a record on the tape that
+ indicates that the file has been deleted at this point.
+ A delete file entry could potentially be one with a FileIndex
+ of 0 or perhaps -1 (need to check if FileIndex is used for
+ some other thing as many of the Bacula fields are "overloaded"
+ in the SD).
During a restore, any file initially picked up by some
backup (Full, ...) then subsequently having a File entry
Make sure this information is stored on the tape too so
that it can be restored directly from the tape.
+ All the code (with the exception of formally generating and
+ saving the delete file entries) already exists in the Verify
+ Catalog command. It explicitly recognizes added/deleted files since
+ the last InitCatalog. It is more or less a "simple" matter of
+ taking that code and adapting it slightly to work for backups.

Comments from Martin Simmons (I think they are all covered):
Ok, that should cover the basics. There are few issues though:
block numbers in btape "test". Possibly adjust in Bacula.
- Fix list volumes to output volume retention in some other
units, perhaps via a directive.
-- If opening a tape in read/write mode fails attempt to open
- it in read-only mode, and mark the tape for read only.
- Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
with multiple priorities.
- If you use restore replace=never, the directory attributes for
- see lzma401.zip in others directory for new compression
algorithm/library.
-- Minimal autochanger handling in Bacula and in btape.
-- Look into how tar does not save sockets and the possiblity of
- not saving them in Bacula (Martin Simmons reported this).
-- Fix restore jobs so that multiple jobs can run if they
- are not using the same tape(s).
- Allow the user to select JobType for manual pruning/purging.
- bscan does not put first of two volumes back with all info in
bscan-test.
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
- Document fact that purge can destroy a part of a restore by purging
one volume while others remain valid -- perhaps mark Jobs.
- Add tree pane to left of window.
- Add progress meter.
- Max wait time or max run time causes seg fault -- see runtime-bug.txt
-- Document writing to a CD/DVD with Bacula.
-- Add a "base" package to the window installer for pthreadsVCE.dll
- which is needed by all packages.
- Add message to user to check for fixed block size when the forward
space test fails in btape.
- When unmarking a directory check if all files below are unmarked and
- Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
- Revisit the question of multiple Volumes (disk) on a single device.
- Add a block copy option to bcopy.
-- Investigate adding Mac Resource Forks.
- Finish work on Gnome restore GUI.
- Fix "llist jobid=xx" where no fileset or client exists.
- For each job type (Admin, Restore, ...) require only the really necessary
to start a job or pass its DHCP obtained IP number.
- Implement a query tape prompt/replace feature for a console
- Copy console @ code to gnome2-console
-- Make AES the only encryption algorithm see
- http://csrc.nist.gov/CryptoToolkit/aes/). It's
- an officially adopted standard, has survived peer
- review, and provides keys up to 256 bits.
-- Take a careful look at SetACL http://setacl.sourceforge.net
- Make tree walk routines like cd, ls, ... more user friendly
by handling spaces better.
- Make sure that Bacula rechecks the tape after the 20 min wait.
in the "short" pool to the "long" pool if this pool runs out of volume
space?
- What to do about "list files job=xxx".
-- Get and test MySQL 4.0
- Look at how fuser works and /proc/PID/fd that is how Nic found the
file descriptor leak in Bacula.
- Implement WrapCounters in Counters.
run the job but don't save the files.
- Make things like list where a file is saved case independent for
Windows.
-- Implement migrate
- Use autochanger to handle multiple devices.
-- On Windows with very long path names, it may be impossible to create
- a file (and thus restore it) because the total length is too long.
- We must cd into the directory then create the file without the
- full path name.
- Implement a Recycle command
-- Test a second language e.g. french.
- Start working on Base jobs.
- Implement UnsavedFiles DB record.
- From Phil Stracchino:
- If SD cannot open a drive, make it periodically retry.
- Add more of the config info to the tape label.
-- If tape is marked read-only, then try opening it read-only rather than
- failing, and remember that it cannot be written.
- Refine SD waiting output:
Device is being positioned
> Device is being positioned for append
- Compare tape to Client files (attributes, or attributes and data)
- Make all database Ids 64 bit.
- Allow console commands to detach or run in background.
-- Fix status delay on storage daemon during rewind.
- Add SD message variables to control operator wait time
- Maximum Operator Wait
- Minimum Message Interval
Migration: Move a backup from one Volume to another
Clone: Copy a backup -- two Volumes
-Bacula Migration is based on Jobs (apparently Networker is file by file).
-
-Migration triggered by:
- Number of Jobs
- Number of Volumes
- Age of Jobs
- Highwater mark (keep total size)
- Lowwater mark
-

======================================================
Base Jobs design
=== Done
-- Make sure that all do_prompt() calls in Dir check for
- -1 (error) and -2 (cancel) returns.
-- Fix foreach_jcr() to have free_jcr() inside next().
- jcr=jcr_walk_start();
- for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
- ...
- jcr_walk_end(jcr);
-- A Volume taken from Scratch should take on the retention period
- of the new pool.
-- Correct doc for Maximum Changer Wait (and others) accepting only
- integers.
-- Implement status that shows why a job is being held in reserve, or
- rather why none of the drives are suitable.
-- 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).
-- Make sure Maximum Volumes is respected in Pools when adding
- Volumes (e.g. when pulling a Scratch volume).
-- Keep same dcr when switching device ...
-- 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).
-- Make catalog respect ACL.
-- Add recycle count to Media record.
-- Add initial write date to Media record.
-- Fix store_yesno to be store_bitmask.

+- Why the heck doesn't bacula drop root priviledges before connecting to
+ the DB?
+- Look at using posix_fadvise(2) for backups -- see bug #751.
+ Possibly add the code at findlib/bfile.c:795
+/* TCP socket options */
+#define TCP_KEEPIDLE 4 /* Start keeplives after this period */
+- Fix bnet_connect() code to set a timer and to use time to
+ measure the time.
+- Implement 4th argument to make_catalog_backup that passes hostname.
+- Test FIFO backup/restore -- make regression
+- Please mount volume "xxx" on Storage device ... should also list
+ Pool and MediaType in case user needs to create a new volume.
+- On restore add Restore Client, Original Client.
