Kern's ToDo List
- 13 August 2005
+ 21 June 2009
-Major development:
-Project Developer
-======= =========
-Version 1.37 Kern (see below)
-========================================================
+Rescue:
+Add to USB key:
+ gftp sshfs kile kate lsssci m4 mtx nfs-common nfs-server
+ patch squashfs-tools strace sg3-utils screen scsiadd
+ system-tools-backend telnet dpkg traceroute urar usbutils
+ whois apt-file autofs busybox chkrootkit clamav dmidecode
+ manpages-dev manpages-posix manpages-posix-dev
-Final items for 1.37 before release:
-1. Fix bugs
-- Look at fixing restore status stats in SD.
-
-- --without-openssl breaks at least on Solaris.
-- Figure out how to package gui, and rescue programs.
-- Test TLS.
-- 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)
Document:
-- datadir for po files.
-- AM_GNU_GETTEXT finds the library if you specify
- --with-libintl-prefix
+- package sg3-utils, program sg_map
+- !!! 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.
-- Restore of all files for a Job or set of jobs even if the file
- records have been removed from the catalog.
+- 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
+- David's priorities
+ Copypools
+ Extract capability (#25)
+ Continued enhancement of bweb
+ Threshold triggered migration jobs (not currently in list, but will be
+ needed ASAP)
+ Client triggered backups
+ Complete rework of the scheduling system (not in list)
+ Performance and usage instrumentation (not in list)
+ See email of 21Aug2007 for details.
+- Look at: http://tech.groups.yahoo.com/group/cfg2html
+ and http://www.openeyet.nl/scc/ for managing customer changes
+
+Priority:
+================
+
+- Fix restore of acls and extended attributes to count ERROR
+ messages and make errors non-fatal.
+- Put save/restore various platform acl/xattrs on a pointer to simplify
+ the code.
+
-For 1.39:
+- Why no error message if restore has no permission on the where
+ directory?
+- Possibly allow manual "purge" to purge a Volume that has not
+ yet been written (even if FirstWritten time is zero) see ua_purge.c
+ is_volume_purged().
+- Add disk block detection bsr code (make it work).
+- Remove done bsrs.
+- Add blast attributes to DIR to SD.
+- Detect deadlocks in reservations.
+- Plugins:
+ - Add list during dump
+ - Add in plugin code flag
+ - Add bRC_EndJob -- stops more calls to plugin this job
+ - Add bRC_Term (unload plugin)
+ - remove time_t from Jmsg and use utime_t?
+- Deadlock detection, watchdog sees if counter advances when jobs are
+ running. With debug on, can do a "status" command.
+- User options for plugins.
+- Pool Storage override precedence over command line.
+- Autolabel only if Volume catalog information indicates tape not
+ written. This will avoid overwriting a tape that gets an I/O
+ error on reading the volume label.
+- I/O error, SD thinks it is not the right Volume, should check slot
+ then disable volume, but Asks for mount.
+- Can be posible modify package to create and use configuration files in
+ the Debian manner?
+
+ For example:
+
+ /etc/bacula/bacula-dir.conf
+ /etc/bacula/conf.d/pools.conf
+ /etc/bacula/conf.d/clients.conf
+ /etc/bacula/conf.d/storages.conf
+
+ and into bacula-dir.conf file include
+
+ @/etc/bacula/conf.d/pools.conf
+ @/etc/bacula/conf.d/clients.conf
+ @/etc/bacula/conf.d/storages.conf
+- Possibly add an Inconsistent state when a Volume is in error
+ for non I/O reasons.
+- Fix #ifdefing so that smartalloc can be disabled. Check manual
+ -- the default is enabled.
+- Change calling sequence to delete_job_id_range() in ua_cmds.c
+ the preceding strtok() is done inside the subroutine only once.
+- Dangling softlinks are not restored properly. For example, take a
+ soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
+ move the directory to another machine where the file /usr/share/autoconf does
+ not exist, back it up, then try a full restore. It fails.
+- Softlinks that point to non-existent file are not restored in restore all,
+ but are restored if the file is individually selected. BUG!
+- New directive "Delete purged Volumes"
+- Prune by Job
+- Prune by Job Level (Full, Differential, Incremental)
+- Strict automatic pruning
+- Implement unmount of USB volumes.
+- Use "./config no-idea no-mdc2 no-rc5" on building OpenSSL for
+ Win32 to avoid patent problems.
+- Implement multiple jobid specification for the cancel command,
+ similar to what is permitted on the update slots command.
+- modify pruning to keep a fixed number of versions of a file,
+ if requested.
+- the cd-command should allow complete paths
+ i.e. cd /foo/bar/foo/bar
+ -> if a customer mails me the path to a certain file,
+ its faster to enter the specified directory
+- Make tree walk routines like cd, ls, ... more user friendly
+ by handling spaces better.
+- When doing a restore, if the user does an "update slots"
+ after the job started in order to add a restore volume, the
+ values prior to the update slots will be put into the catalog.
+ Must retrieve catalog record merge it then write it back at the
+ end of the restore job, if we want to do this right.
+=== rate design
+ jcr->last_rate
+ jcr->last_runtime
+ MA = (last_MA * 3 + rate) / 4
+ rate = (bytes - last_bytes) / (runtime - last_runtime)
+- 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.
+- Scripts
+- Auto update of slot:
+ rufus-dir: ua_run.c:456-10 JobId=10 NewJobId=10 using pool Full priority=10
+ 02-Nov 12:58 rufus-dir JobId 10: Start Backup JobId 10, Job=kernsave.2007-11-02_12.58.03
+ 02-Nov 12:58 rufus-dir JobId 10: Using Device "DDS-4"
+ 02-Nov 12:58 rufus-sd JobId 10: Invalid slot=0 defined in catalog for Volume "Vol001" on "DDS-4" (/dev/nst0). Manual load my be required.
+ 02-Nov 12:58 rufus-sd JobId 10: 3301 Issuing autochanger "loaded? drive 0" command.
+ 02-Nov 12:58 rufus-sd JobId 10: 3302 Autochanger "loaded? drive 0", result is Slot 2.
+ 02-Nov 12:58 rufus-sd JobId 10: Wrote label to prelabeled Volume "Vol001" on device "DDS-4" (/dev/nst0)
+ 02-Nov 12:58 rufus-sd JobId 10: Alert: TapeAlert[7]: Media Life: The tape has reached the end of its useful life.
+ 02-Nov 12:58 rufus-dir JobId 10: Bacula rufus-dir 2.3.6 (26Oct07): 02-Nov-2007 12:58:51
+- Separate Files and Directories in catalog
+- Create FileVersions table
+- Look at rsysnc for incremental updates and dedupping
+- Add MD5 or SHA1 check in SD for data validation
+- finish implementation of fdcalled -- see ua_run.c:105
+- Fix problem in postgresql.c in my_postgresql_query, where the
+ generation of the error message doesn't differentiate result==NULL
+ and a bad status from that result. Not only that, the result is
+ cleared on a bail_out without having generated the error message.
+- KIWI
+- Implement SDErrors (must return from SD)
+- Implement USB keyboard support in rescue CD.
+- Implement continue spooling while despooling.
+- Remove all install temp files in Win32 PLUGINSDIR.
+- Audit retention periods to make sure everything is 64 bit.
+- No where in restore causes kaboom.
+- Performance: multiple spool files for a single job.
+- Performance: despool attributes when despooling data (problem
+ multiplexing Dir connection).
+- Make restore use the in-use volume reservation algorithm.
+- 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.
+- 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.
+
+- 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.
+- Doc items
+- Test Volume compatibility between machine architectures
+- Encryption documentation
+- Wrong jobbytes with query 12 (todo)
+- Bare-metal recovery Windows (todo)
+
+
+Projects:
+- Pool enhancements
+ - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
+ - Pool Type = Copy
+ - Maximum number of scratch volumes
+ - Maximum File size
+ - Next Pool (already have)
+ - Reclamation threshold
+ - Reclamation Pool
+ - Reuse delay (after all files purged from volume before it can be used)
+ - Copy Pool = xx, yyy (or multiple lines).
+ - Catalog = xxx
+ - Allow pool selection during restore.
+
+- 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
+ - Despool attributes in separate thread
+ - Database speedups
+ - Embedded MySQL
+ - Check why restore repeatedly sends Rechdrs between
+ each data chunk -- according to James Harper 9Jan07.
+- Features
+ - Better scheduling
+ - More intelligent re-run
+ - FD plugins
+ - Incremental backup -- rsync, Stow
+
+For next release:
+- Try to fix bscan not working with multiple DVD volumes bug #912.
+- Look at mondo/mindi
+- 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.
+- 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

+- 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
- 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.
- Bug: if a job is manually scheduled to run later, it does not appear
in any status report and cannot be cancelled.
-==== 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.

+====
+From David:
+How about introducing a Type = MgmtPolicy job type? That job type would
+be responsible for scanning the Bacula environment looking for specific
+conditions, and submitting the appropriate jobs for implementing said
+policy, eg:
+
+Job {
+ Name = "Migration-Policy"
+ Type = MgmtPolicy
+ Policy Selection Job Type = Migrate
+ Scope = "<keyword> <operator> <regexp>"
+ Threshold = "<keyword> <operator> <regexp>"
+ Job Template = <template-name>
+}
+
+Where <keyword> is any legal job keyword, <operator> is a comparison
+operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
+appropriate regexp. I could see an argument for Scope and Threshold
+being SQL queries if we want to support full flexibility. The
+Migration-Policy job would then get scheduled as frequently as a site
+felt necessary (suggested default: every 15 minutes).
+
+Example:
+
+Job {
+ Name = "Migration-Policy"
+ Type = MgmtPolicy
+ Policy Selection Job Type = Migration
+ Scope = "Pool=*"
+ Threshold = "Migration Selection Type = LowestUtil"
+ Job Template = "MigrationTemplate"
+}
+
+would select all pools for examination and generate a job based on
+MigrationTemplate to automatically select the volume with the lowest
+usage and migrate it's contents to the nextpool defined for that pool.
+
+This policy abstraction would be really handy for adjusting the behavior
+of Bacula according to site-selectable criteria (one thing that pops
+into mind is Amanda's ability to automatically adjust backup levels
+depending on various criteria).

-- 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?
-- Document security problems with the same password for everyone in
- rpm and Win32 releases.
- Browse generations of files.
- I've seen an error when my catalog's File table fills up. I
then have to recreate the File table with a larger maximum row
- 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.
- When an error in input occurs and conio beeps, you can back
up through the prompt.
- Detect fixed tape block mode during positioning by looking at
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

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.
-- Implement the FreeBSD nodump flag in chflags.
- Figure out how to make named console messages go only to that
console and to the non-restricted console (new console class?).
- Make restricted console prompt for password if *ask* is set or
-> maybe its more easy to maintain this, if the
descriptions of that commands are outsourced to
a ceratin-file
-- the cd-command should allow complete paths
- i.e. cd /foo/bar/foo/bar
- -> if a customer mails me the path to a certain file,
- its faster to enter the specified directory
- if the password is not configured in bconsole.conf
you should be asked for it.
-> sometimes you like to do restore on a customer-machine
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
fields.- Pass Director resource name as an option to the Console.
- 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.
- Allow browsing the catalog to see all versions of a file (with
stat data on each file).
- Restore attributes of directory if replace=never set but directory
- Check new HAVE_WIN32 open bits.
- Check if the tape has moved before writing.
- Handling removable disks -- see below:
-- Keep track of tape use time, and report when cleaning is necessary.
- Add FromClient and ToClient keywords on restore command (or
BackupClient RestoreClient).
- 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 timeout BSOCK packets after a specific delay.
-- 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.
- 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.
-- Make multiple restore jobs for multiple media types specifying
- the proper storage type.
- Fix fast block rejection (stored/read_record.c:118). It passes a null
pointer (rec) to try_repositioning().
-- Look at extracting Win data from BackupRead.
- Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
which would take precidence over the Catalog "JobRetention".
- Implement Label Format in Add and Label console commands.
-- Possibly up network buffers to 65K. Put on variable.
- Put email tape request delays on one or more variables. User wants
to cancel the job after a certain time interval. Maximum Mount Wait?
- Job, Client, Device, Pool, or Volume?
support for Oracle database ??
===
- Look at adding SQL server and Exchange support for Windows.
-- Make dev->file and dev->block_num signed integers so that -1 can
- be an invalid value which happens with BSR.
- Create VolAddr for disk files in place of VolFile and VolBlock. This
is needed to properly specify ranges.
- Add progress of files/bytes to SD and FD.
- Implement some way for the File daemon to contact the Director
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

-- 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.
- Set IO_NOWAIT on Bacula TCP/IP packets.
- Try doing a raw partition backup and restore by mounting a
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

- Can we dynamically change FileSets?
- If pool specified to label command and Label Format is specified,
automatically generate the Volume name.

- Add ExhautiveRestoreSearch
- Look at the possibility of loading only the necessary
data into the restore tree (i.e. do it one directory at a
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

- Start working on Base jobs.
-- Implement UnsavedFiles DB record.
- From Phil Stracchino:
It would probably be a per-client option, and would be called
something like, say, "Automatically purge obsoleted jobs". What it
- 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
- Have SD compute MD5 or SHA1 and compare to what FD computes.
- Make VolumeToCatalog calculate an MD5 or SHA1 from the
actual data on the Volume and compare it.
-- Implement Bacula plugins -- design API
- Make bcopy read through bad tape records.
- Program files (i.e. execute a program to read/write files).
Pass read date of last backup, size of file last time.
- bscan without -v is too quiet -- perhaps show jobs.
- Add code to reject whole blocks if not wanted on restore.
- Check if we can increase Bacula FD priorty in Win2000
-- Make sure the MaxVolFiles is fully implemented in SD
- Check if both CatalogFiles and UseCatalog are set to SD.
- Possibly add email to Watchdog if drive is unmounted too
long and a job is waiting on the drive.
- 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

- Make database type selectable by .conf files i.e. at runtime
- Set flag for uname -a. Add to Volume label.
- Restore files modified after date
- MaxWarnings
- MaxErrors (job?)

- Write a Storage daemon that uses pipes and
standard Unix programs to write to the tape.

times out jobs by asking the deamons where they are.
- Enhance Jmsg code to permit buffering and saving to disk.

without it.
-3. Restoring deleted files: Since I think my comments in (2) above
-have low probability of implementation, I'll also suggest that you
-could approach the issue of deleted files by a mechanism of having the
-fd report to the dir, a list of all files on the client for every
-backup job. The dir could note in the database entry for each file
-the date that the file was seen. Then if a restore as of date X takes
-place, only files that exist from before X until after X would be
-restored. Probably the major cost here is the extra date container in
-each row of the files table.
-
-Thanks for "listening". I hope some of this helps. If you want to
-contact me, please send me an email - I read some but not all of the
-mailing list traffic and might miss a reply there.
-
-Please accept my compliments for bacula. It is doing a great job for
-me!! I sympathize with you in the need to wrestle with excelence in
-execution vs. excelence in feature inclusion.

==============================
Longer term to do:
-- Design at hierarchial storage for Bacula. Migration and Clone.
- Implement FSM (File System Modules).
- Audit M_ error codes to ensure they are correct and consistent.
- Add variable break characters to lex analyzer.
continue a save if the Director goes down (this
is NOT currently the case). Must detect socket error,
buffer messages for later.
-- Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
- Add ability to backup to two Storage devices (two SD sessions) at
the same time -- e.g. onsite, offsite.
-- Add the ability to consolidate old backup sets (basically do a restore
- to tape and appropriately update the catalog). Compress Volume sets.
- Might need to spool via file is only one drive is available.
-- Compress or consolidate Volumes of old possibly deleted files. Perhaps
- someway to do so with every volume that has less than x% valid
- files.
-
-
-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
VolSessionId and VolSessionTime.

-==========================================================
- Unsaved File design
-For each Incremental job that is run, there may be files that
-were found but not saved because they were locked (this applies
-only to Windows). Such a system could send back to the Director
-a list of Unsaved files.
-Need:
-- New UnSavedFiles table that contains:
- JobId
- PathId
- FilenameId
-- Then in the next Incremental job, the list of Unsaved Files will be
- feed to the FD, who will ensure that they are explicitly chosen even
- if standard date/time check would not have selected them.

Handling removable disks
=== 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.

- 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, ...
-- 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.
-- Upgrade to MySQL 4.1.12 See:
- http://dev.mysql.com/doc/mysql/en/Server_SQL_mode.html
-- Add # Job Level date to bsr file
-- Implement "PreferMountedVolumes = yes|no" in Job resource.
-## Integrate web-bacula into a new Bacula project with
- bimagemgr.
-- Cleaning tapes should have Status "Cleaning" rather than append.
-- Make sure that Python has access to Client address/port so that
- it can check if Clients are alive.
-- Review all items in "restore".
-- Fix PostgreSQL GROUP BY problems in restore.
-- Fix PostgreSQL sql problems in bugs.
-- After rename
- 04-Jul 13:01 MainSD: Rufus.2005-07-04_01.05.02 Warning: Director wanted Volume
- "DLT-13Feb04".
- Current Volume "DLT-04Jul05" not acceptable because:
- 1997 Volume "DLT-13Feb04" not in catalog.
- 04-Jul 13:01 MainSD: Please mount Volume "DLT-04Jul05" on Storage Device
- "HP DLT 80" (/dev/nst0) for Job Rufus.2005-07-04_01.05.02
-## Create a new GUI chapter explaining all the GUI programs.
-- Make "update slots" when pointing to Autochanger, remove
- all Volumes from other drives. "update slots all-drives"?
- No, this is done by modifying mtx-changer to list what is
- in the drives.
-- 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:
- 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.
-- 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

+- Fix bpipe.c so that it does not modify results pointer.
+ ***FIXME*** calling sequence should be changed.
