Kern's ToDo List
- 18 December 2003
+ 27 January 2004
Documentation to do: (any release a little bit at a time)
- Document running a test version.
- Create a man page for each binary (Debian package requirement).
Testing to do: (painful)
+- Test drive polling!
- that ALL console command line options work and are always implemented
- blocksize recognition code.
- Test if rewind at end of tape waits for tape to rewind.
- Test cancel at EOM.
For 1.33 Testing/Documentation:
+- Newly labeled tapes are chosen before ones already in use.
- Document new alias records in Director. SDAddress SDDeviceName, SDPassword.
FDPassword, FDAddress, DBAddress, DBPort, DBPassword.
- Document new Include/Exclude ...
- Add counter variable test.
- Document ln -sf /usr/lib/libncurses.so /usr/lib/libtermcap.so
and install the esound-dev package for compiling Console on SuSE.
+ This should read 'Document LDFLAGS="-L/usr/lib/termcap" ... '
- Add an example of using a FIFO in dirdconf.wml
- Add an item to the FAQ about running jobs in different timezones.
- Add some examples of job editing codes.
- Add db check test to regression. Test each function like delete,
purge, ...
- Add subsections to the Disaster Recovery index section.
-
+- Document Pool keyword for restore.
+- If you use restore replace=never, the directory attributes for
+ non-existent directories will not be restored properly.
+- In the Bacula User Guide you write:"Note, one major disadvantage of
+ writing to a NFS mounted volume as I do isthat if the other machine goes
+ down, the OS will wait forever on the fopen()call that Bacula makes. As
+ a consequence, Bacula will completely stall untilthe machine exporting
+ the NSF mounts comes back up. If someone knows a wayaround this, please
+ let me know."I haven't tried using NFS in years, but I think that the
+ "soft" and "intr"remount options may well help you. The only way of
+ being sure would be totry it.See, for example,
+ http://howtos.linux.com/guides/nag2/x-087-2-nfs.mountd.shtml

For 1.33
-- Look at Dan's field width problems in PostgreSQL.
-- In restore take all filesets with same base name.
-- From Alan Brown <ajb2@mssl.ucl.ac.uk>
- BTW, there's a make install bug in 1.33 - with --enable-gnome,
- gnome-console is built, but the binary and .conf are not being installed.
-- Make Scheduler sort jobs by StartTime, Priority.
-- Make sure smtp and any other useful program is executable by the world
- in case Bacula is not running as root.
+- Allow "delete job jobid=xx jobid=xxx".
+- Allow "delete job jobid=xxx,yyy,aaa-bbb" i.e. list + ranges.
+- Implement multiple Volume in "purge jobs volume=".
+- Implement a JobSet, which groups any number of jobs. If the
+ JobSet is started, all the jobs are started together.
+ Allow Pool, Level, and Schedule overrides.
+- Enhance cancel to timout BSOCK packets after a specific delay.
+- When I restore to Windows the Created, Accessed and Modifiedtimes are
+ those of the time of the restore, not those of the originalfile.
+ The dates you will find in your restore log seem to be the original
+ creation dates
+- Rescue builds incorrect script files on Rufus.
+- Write a Qmsg() to be used in bnet.c to prevent recursion. Queue the
+ message. If dequeueing toss the messages. Lock while dequeuing so that
+ it cannot be called recursively and set dequeuing flag.
+- Add all pools in Dir conf to DB also update them to catch changed
+ LabelFormats and such.
+- Symbolic link a directory to another one, then backup the symbolic
+ link.
+- Build console in client-only build.
+- Restore attributes of directory if replace=never set but directory
+ did not exist.
+- Check why Phil's Verify exclude does not work.
+- Phil says that Windows file sizes mismatch in Verify when they should,
+ and that either the file size or the catalog size was zero.
+- Fix option 2 of restore -- list where file is backed up -- require Client,
+ then list last 20 backups.
+- Allow browsing the catalog to see all versions of a file (with
+ stat data on each file).
+- Finish code passing files=nnn to restore start.
+- Add level to estimate command.
+- Check time/dates printed during restore when using Win32 API.
+- Volume "add"ed to Pool gets recycled in first use. VolBytes=0
+- Get rid of 0 dates in LastWritten, ...
+- Fix "llist jobid=xx" where no fileset or client exists.
+- Release SQLite 2.8.9
+- If a tape is recycled while it is mounted, Stanislav Tvrudy must do an
+ additional mount to deblock the job.
+- From Johan Decock:
+ bscan: sql_update.c:65 UPDATE File SET MD5='Ij+5kwN6TFIxK+8l8+/I+A' WHERE FileId=0
+ bscan: bscan.c:1074 Could not add MD5/SHA1 to File record. ERR=sql_update.c:65 Update problem: affected_rows=0
+- Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
+ ua_status.!!! Thanks to Alan Brown for this tip.
- Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
correctly for multiple simultaneous jobs.
- Correct code so that FileSet MD5 is calculated for < and | filename
generation.
-- Permit Bacula and apcupsd donations.
- Mark Volume in error on error from WEOF.
- Why does Bacula need the drive open to do "autochanger list" ?
- Add a .list all files in the restore tree (probably also a list all files)
Do both a long and short form.
-- Add a Media record flag that indicates that the Volume does disk
+- Implement the Media record flag that indicates that the Volume does disk
addressing.
- Implement VolAddr, which is used when Volume is addressed like a disk,
and form it from VolFile and VolBlock.
resources, like Level? If so, I think I'd make it an optional directive
in Job, Client, and Pool, with precedence such that Job overrides Client
which in turn overrides Pool.
-- Fix Ctl-C crashing the Console (readline?).
+- Print a message when a job starts if the conf file is not current.
- Finish work on conio.c
- To pass Include 1 or two letter commands
I Name Include name - first record
F Number Number of filenames to follow
<file-name>

+

+
+ True, with the exception that if you have enough disk spool space,
+ and you want to run concurrent jobs, spooling can eliminate the block
+ interleaving restore inefficiencies.
+
+ > And you should be able to turn it of by sd for sd-machines with low disk

+
+ Having multiple directories is no problem -- having different maximum
+ sizes creates specification problems. At some point, I will probably
+ have a common SD pool of spool directories as well as a set of
+ private spool directories for each device. The first implementation
+ will be a set of private spool directories for each device since
+ managing a global pool with a bunch of threads writing into the same
+ directory is *much* more complicated and prone to error.
+
+ > - the ability to spool parts of a backup (not the whole client)
+
+ This may change in the future, but for the moment, it will spool
+ either to a job high water mark, or until the directory is full
+ (reaches max spool size or I/O error). It will then write to tape,
+ truncate the spool file, and begin spooling again.
+
+ > - spooling while writing to tape
+
+ Not within a job, but yes, if you run concurrent jobs -- each is a
+ different thread. Within a job could be a feature, but *much* later.
+
+ > - parallel spooling (like parallel jobs/ concurrent jobs) of clients
+
+ Yes, this is one of my main motivations for doing it (aside from
+ eliminating tape "shoe shine" during incremental backups.
+
+ > - flushing a backup that only went to disk (like amflush in amanda)
+
+ This will be a future feature, since spooling is different from backing
+ up to disk. The future feature will be "migration" which will move a job
+ from one backup Volume to another.
+
- New Storage specifications:
Passed to SD as a sort of BSR record called Storage Specification
Record or SSR.
In SD allow Device to have Multiple MediaTypes
After 1.33:
+- Look at www.nu2.nu/pebuilder as a helper for full windows
+ bare metal restore.
+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.
+Ideas from Jerry Scharf:
+ First let's point out some big pluses that bacula has for this
+ it's open source
+ more importantly it's active. Thank you so much for that
+ even more important, it's not flaky
+ it has an open access catalog, opening many possibilities
+ it's pushing toward heterogeneous systems capability
+ simple things:
+ I don't remember an include file directive for config files
+ (not filesets, actual config directives)
+ can you check the configs without starting the daemon?
+ some warnings about possible common mistakes
+ big things:
+ doing the testing and blessing of concurrent backup writes
+ this is absolutely necessary in the enterprise
+ easy user recovery GUI with full access checking
+ Macintosh file client
+ macs are an interesting niche, but I fear a server is a rathole
+ working bare iron recovery for windows
+ much better handling on running config changes
+ thinking through the logic of what happens to jobs in progress
+ the option for inc/diff backups not reset on fileset revision
+ a) use both change and inode update time against base time
+ b) do the full catalog check (expensive but accurate)
+ sizing guide (how much system is needed to back up N systems/files)
+ consultants on using bacula in building a disaster recovery system
+ an integration guide
+ or how to get at fancy things that one could do with bacula
+ logwatch code for bacula logs (or similar)
+ linux distro inclusion of bacula (brings good and bad, but necessary)
+ win2k/XP server capability (icky but you asked)
+ support for Oracle database ??
+===
- Look at adding SQL server and Exchange support for Windows.
- Restore: Enter Filename: 'C:/Documents and Settings/Comercial/My
Documents/MOP/formulário de registro BELAS ARTES.doc' causes Bacula to
Job report (Volker Sauer).
- Client does not show busy during Estimate command.
- Implement Console mtx commands.
-- Look at 2Gb limit for SQLite.
-- Implement 3 Pools for a Job:
- Job {
- Name = ...
- Full Backup Pool = xxx
- Incremental Backup Pool = yyy
- Differential Backup Pool = zzz
- }
- Add a default DB password to MySQL.
GRANT all privileges ON bacula.* TO bacula@localhost IDENTIFIED BY
'bacula_password';
FLUSH PRIVILEGES;
-- Define week of year for scheduler. W01, W02, ...
- Week 01 of a year is per definition the first week that has the
- Thursday in this year, which is equivalent to the week that contains the
- fourth day of January. In other words, the first week of a new year is
- the week that has the majority of its days in the new year. Week 01
- might also contain days from the previous year and the week before week
- 01 of a year is the last week (52 or 53) of the previous year even if it
- contains days from the new year. A week starts with Monday (day 1) and
- ends with Sunday (day 7). For example, the first week of the year 1997
- lasts from 1996-12-30 to 1997-01-05 and can be written in standard
- notation as
-
- 1997-W01 or 1997W01
-
- The week notation can also be extended by a number indicating the day
- of the week. For example, the day 1996-12-31, which is the Tuesday (day
- 2) of the first week of 1997, can also be written as
-
- 1997-W01-2 or 1997W012
-
- Implement a Mount Command and an Unmount Command where
the users could specify a system command to be performed
to do the mount, after which Bacula could attempt to
- Take a careful look at Level for the estimate command, maybe make
it a command line option.
- Add Volume name to "I cannot write on this volume because"
-- Make restore job check if all the files are actually restored.
- Make tree walk routines like cd, ls, ... more user friendly
by handling spaces better.
- Write your PID file and chown root:wheel before drop.
- Set IO_NOWAIT on Bacula TCP/IP packets.
- Try doing a raw partition backup and restore by mounting a
Windows partition.
-- Report CVS problems to SourceForge.
-- Implement .consolerc for Console
-- From Lars Köllers:
+- From Lars Kellers:
Yes, it would allow to highly automatic the request for new tapes. If a
tape is empty, bacula reads the barcodes (native or simulated), and if
an unused tape is found, it runs the label command with all the
By the way can bacula automatically "move" an empty/purged volume say
in the "short" pool to the "long" pool if this pool runs out of volume
space?
-- Either restrict the characters in a name, or fix the problem
- emailing with names containing / (smtp command line breaks).
- Eliminate orphaned jobs: dbcheck, normal pruning, delete job command.
Hm. Well, there are the remaining orphaned job records:
- Walk through the Pool records rather than the Job records
in dird.c to create/update pools.
- What to do about "list files job=xxx".
-- Implement scan: for every slot it finds, zero the slot of
- Volume other volume having that slot.
- When job rescheduled, status gives is waiting for Client Rufus
to connect to Storage File. Dir needs to inform SD that job
is rescheduled.
-- Fix get_storage_from_media_type (ua_restore) to use command line
- storage=
-- Don't print "Warning: Wrong Volume mounted ..." if mounting second volume.
- Make Dmsg look at global before calling subroutine.
- Enable trace output at runtime for Win32
- Available volumes for autochangers (see patrick@baanboard.com 3 Sep 03
- Get and test MySQL 4.0
- Do a complete audit of all pthreads_mutex, cond, ... to ensure that
any that are dynamically initialized are destroyed when no longer used.
-- Write a mini-readline with history and editing.
- Look at how fuser works and /proc/PID/fd that is how Nic found the
file descriptor leak in Bacula.
- Implement WrapCounters in Counters.
- Can we dynamically change FileSets?
- If pool specified to label command and Label Format is specified,
automatically generate the Volume name.
-- Take a careful look a the Basic recycling algorithm. When Bacula
- chooses, the order should be:
- - Look for Append
- - Look for Recycle or Purged
- - Prune volumes
- - Look for purged
- Instead of using lowest media Id, find the least recently used
- volume.
-
- When the tape is mounted and Bacula requests the status
- - Do everything possible to use it.
-
- Define a "available" status, which is the currently mounted
- Volume and all volumes that are currently in the autochanger.
-
- Why can't SQL do the filename sort for restore?
-- Is a pool specification really needed for a restore? Yes, and
- you may want to exclude archive Pools.
- Look at libkse (man kse) for FreeBSD threading.
- Look into Microsoft Volume Shadowcopy Service VSS for backing
up system state components (Active Directory, System Volume, ...)
time as the user walks through the tree).
- Possibly use the hash code if the user selects all for a restore command.
- Orphaned Dir buffer at parse_conf.c:373 => store_dir
-- Add Console usr permissions.
- Fix "restore all" to bypass building the tree.
-- Fix restore to list errors if Invalid block found, and if # files
- restored does not match # expected.
- Prohibit backing up archive device (findlib/find_one.c:128)
- Implement Release Device in the Job resource to unmount a drive.
- Implement Acquire Device in the Job resource to mount a drive,
- Make things like list where a file is saved case independent for
Windows.
- Implement migrate
-- Implement a PostgreSQL driver.
- Bacula needs to propagate SD errors.

We must cd into the directory then create the file without the
full path name.
- lstat() is not going to work on Win32 for testing date.
-- Something is not right in last block of fill command.
- Implement a Recycle command
-- Add FileSet to command line arguments for restore.
- Add client name to cram-md5 challenge so Director can immediately
verify if it is the correct client.
- Add JobLevel in FD status (but make sure it is defined).
- Implement restore "current system", but take all files without
doing selection tree -- so that jobs without File records can
be restored.
-- Implement a relocatable bacula.spec
- Add prefixlinks to where or not where absolute links to FD.
- Issue message to mount a new tape before the rewind.
- Simplified client job initiation for portables.
- Add UA rc and history files.
- put termcap (used by console) in ./configure and
allow -with-termcap-dir.
-- Enhance time and size scanning routines.
- Fix Autoprune for Volumes to respect need for full save.
- Fix Win32 config file definition name on /install
