15 - During tests with the 260 char fix code, I found one problem:
16 if the system "sees" a long path once, it seems to forget it's
17 working drive (e.g. c:\), which will lead to a problem during
18 the next job (create bootstrap file will fail). Here is the
19 workaround: specify absolute working and pid directory in

49 and possibly changing the blobs into varchar.
50 - Check if gnome-console works with TLS.

132 - It appears to me that you have run into some sort of race
133 condition where two threads want to use the same Volume and they
134 were both given access. Normally that is no problem. However,
135 one thread wanted the particular Volume in drive 0, but it was
136 loaded into drive 1 so it decided to unload it from drive 1 and
137 then loaded it into drive 0, while the second thread went on
138 thinking that the Volume could be used in drive 1 not realizing
139 that in between time, it was loaded in drive 0.
140 I'll look at the code to see if there is some way we can avoid
141 this kind of problem. Probably the best solution is to make the
142 first thread simply start using the Volume in drive 1 rather than
143 transferring it to drive 0.
144 - Fix re-read of last block to check if job has actually written
145 a block, and check if block was written by a different job
146 (i.e. multiple simultaneous jobs writing).
147 - Figure out how to configure query.sql. Suggestion to use m4:
148 == changequote.m4 ===
149 changequote(`[',`]')dnl

153 Pool.Name AS PoolName,
158 [ FROM_UNIXTIME(UNIX_TIMESTAMP(Media.LastWritten) Media.VolRetention) AS Expire, ])dnl
160 [ media.lastwritten + interval '1 second' * media.volretention as expire, ])dnl
164 ON Media.PoolId=Pool.PoolId
165 WHERE Media.LastWritten>0
169 Command: m4 -DmySQL changequote.m4 query.sql.in >query.sql
171 The problem is that it requires m4, which is not present on all machines
173 - Given all the problems with FIFOs, I think the solution is to do something a
174 little different, though I will look at the code and see if there is not some
175 simple solution (i.e. some bug that was introduced). What might be a better
176 solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
177 write data to a program rather than the FIFO. For example, suppose you
182 Then, I could imagine if you backup and restore this file with a direct
183 reference as is currently done for fifos, instead, during backup Bacula will
186 /home/kern/my-fifo.backup
188 and read the data that my-fifo.backup writes to stdout. For restore, Bacula
191 /home/kern/my-fifo.restore
193 and send the data backed up to stdout. These programs can either be an
194 executable or a shell script and they need only read/write to stdin/stdout.
196 I think this would give a lot of flexibility to the user without making any
197 significant changes to Bacula.

214 === Migration from David ===
215 What I'd like to see:
218 Name = "<poolname>-migrate"
222 Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
223 Client | PoolResidence | Volume | JobName | SQLquery
224 Migration Selection Pattern = "regexp"
225 Next Pool = <override>
228 There should be no need for a Level (migration is always Full, since you
229 don't calculate differential/incremental differences for migration),
230 Storage should be determined by the volume types in the pool, and Client
231 is really a selection issue. Migration should always occur to the
232 NextPool defined in the pool definition. If no nextpool is defined, the
233 job should end with a reason of "no place to go". If Next Pool statement
234 is present, we override the check in the pool definition and use the
237 Here's how I'd define Migration Selection Types:
240 Client -- Migrate data from selected client only. Migration Selection
241 Pattern regexp provides pattern to select client names, eg ^FS00* makes
242 all client names starting with FS00 eligible for migration.
244 Jobname -- Migration all jobs matching name. Migration Selection Pattern
245 regexp provides pattern to select jobnames existing in pool.
247 Volume -- Migrate all data on specified volumes. Migration Selection
248 Pattern regexp provides selection criteria for volumes to be migrated.
249 Volumes must exist in pool to be eligible for migration.
253 LowestUtil -- Identify the volume in the pool with the least data on it
254 and empty it. No Migration Selection Pattern required.
256 OldestVol -- Identify the LRU volume with data written, and empty it. No
257 Migration Selection Pattern required.
259 PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
260 (starting with most full volumes) until pool occupancy drops below
261 <lowmig>. Pool highmig and lowmig values are in pool definition, no
262 Migration Selection Pattern required.
266 SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
267 Migration Selection Pattern contains SQL query to execute; should return
268 a list of 1 or more jobuids to migrate.
270 PoolResidence -- Migrate data sitting in pool for longer than
271 PoolResidence value in pool definition. Migration Selection Pattern
272 optional; if specified, override value in pool definition (value in

450 1. When jobs are running and bacula for some reason crashes or if I do a
451 restart it remembers and jobs it was running before it crashed or restarted
452 as of now I loose all jobs if I restart it.
454 2. When spooling and in the midway if client is disconnected for instance a
455 laptop bacula completely discard the spool. It will be nice if it can write
456 that spool to tape so there will be some backups for that client if not all.
458 3. We have around 150 clients machines it will be nice to have a option to
459 upgrade all the client machines bacula version automatically.
461 4. Atleast one connection should be reserved for the bconsole so at heavy load
462 I should connect to the director via bconsole which at sometimes I can't
464 5. Another most important feature that is missing, say at 10am I manually
465 started backup of client abc and it was a full backup since client abc has
466 no backup history and at 10.30am bacula again automatically started backup of
467 client abc as that was in the schedule. So now we have 2 multiple Full
468 backups of the same client and if we again try to start a full backup of
469 client backup abc bacula won't complain. That should be fixed.
471 - Fix bpipe.c so that it does not modify results pointer.
472 ***FIXME*** calling sequence should be changed.
473 - For Windows disaster recovery see http://unattended.sf.net/
474 - regardless of the retention period, Bacula will not prune the
475 last Full, Diff, or Inc File data until a month after the
476 retention period for the last Full backup that was done.
477 - update volume=xxx --- add status=Full
478 - Remove old spool files on startup.
479 - Exclude SD spool/working directory.
480 - Refuse to prune last valid Full backup. Same goes for Catalog.
482 - Make a callback when Rerun failed levels is called.
483 - Give Python program access to Scheduled jobs.
484 - Add setting Volume State via Python.
485 - Python script to save with Python, not save, save with Bacula.
486 - Python script to do backup.
488 - Change the Priority, Client, Storage, JobStatus (error)
489 at the start of a job.
490 - Why is SpoolDirectory = /home/bacula/spool; not reported
491 as an error when writing a DVD?
492 - Make bootstrap file handle multiple MediaTypes (SD)
493 - Remove all old Device resource code in Dir and code to pass it
494 back in SD -- better, rework it to pass back device statistics.
495 - Check locking of resources -- be sure to lock devices where previously
496 resources were locked.
497 - The last part is left in the spool dir.
500 - In restore don't compare byte count on a raw device -- directory
501 entry does not contain bytes.
505 MA = (last_MA * 3 + rate) / 4
506 rate = (bytes - last_bytes) / (runtime - last_runtime)
507 - Max Vols limit in Pool off by one?
508 - Implement Files/Bytes,... stats for restore job.
509 - Implement Total Bytes Written, ... for restore job.
510 - Despool attributes simultaneously with data in a separate
511 thread, rejoined at end of data spooling.
512 - 7. Implement new Console commands to allow offlining/reserving drives,
513 and possibly manipulating the autochanger (much asked for).
514 - Add start/end date editing in messages (%t %T, %e?) ...
515 - Add ClientDefs similar to JobDefs.
516 - Print more info when bextract -p accepts a bad block.
517 - Fix FD JobType to be set before RunBeforeJob in FD.
518 - Look at adding full Volume and Pool information to a Volume
519 label so that bscan can get *all* the info.
520 - If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
521 and there is only one volume in the pool, refuse to do it -- otherwise
522 he fills the Volume, then immediately starts reusing it.
523 - Implement copies and stripes.
524 - Add history file to console.
525 - Each file on tape creates a JobMedia record. Peter has 4 million
526 files spread over 10000 tape files and four tapes. A restore takes
527 16 hours to build the restore list.
528 - Add and option to check if the file size changed during backup.
529 - Make sure SD deletes spool files on error exit.
530 - Delete old spool files when SD starts.
531 - When labeling tapes, if you enter 000026, Bacula uses
532 the tape index rather than the Volume name 000026.
533 - Add offline tape command to Bacula console.
535 Enter MediaId or Volume name: 32
536 Enter new Volume name: DLT-20Dec04

547 - Bug: if a job is manually scheduled to run later, it does not appear
548 in any status report and cannot be cancelled.
550 ==== Keeping track of deleted/new files ====
551 - To mark files as deleted, run essentially a Verify to disk, and
552 when a file is found missing (MarkId != JobId), then create
553 a new File record with FileIndex == -1. This could be done
554 by the FD at the same time as the backup.
556 My "trick" for keeping track of deletions is the following.
557 Assuming the user turns on this option, after all the files
558 have been backed up, but before the job has terminated, the
559 FD will make a pass through all the files and send their
560 names to the DIR (*exactly* the same as what a Verify job
561 currently does). This will probably be done at the same
562 time the files are being sent to the SD avoiding a second
563 pass. The DIR will then compare that to what is stored in
564 the catalog. Any files in the catalog but not in what the
565 FD sent will receive a catalog File entry that indicates
566 that at that point in time the file was deleted. This
567 either transmitted to the FD or simultaneously computed in
568 the FD, so that the FD can put a record on the tape that
569 indicates that the file has been deleted at this point.
570 A delete file entry could potentially be one with a FileIndex
571 of 0 or perhaps -1 (need to check if FileIndex is used for
572 some other thing as many of the Bacula fields are "overloaded"
575 During a restore, any file initially picked up by some
576 backup (Full, ...) then subsequently having a File entry
577 marked "delete" will be removed from the tree, so will not
578 be restored. If a file with the same name is later OK it
579 will be inserted in the tree -- this already happens. All
580 will be consistent except for possible changes during the
583 Since I'm on the subject, some of you may be wondering what
584 the utility of the in memory tree is if you are going to
585 restore everything (at least it comes up from time to time
586 on the list). Well, it is still *very* useful because it
587 allows only the last item found for a particular filename
588 (full path) to be entered into the tree, and thus if a file
589 is backed up 10 times, only the last copy will be restored.
590 I recently (last Friday) restored a complete directory, and
591 the Full and all the Differential and Incremental backups
592 spanned 3 Volumes. The first Volume was not even mounted
593 because all the files had been updated and hence backed up
594 since the Full backup was made. In this case, the tree
595 saved me a *lot* of time.
597 Make sure this information is stored on the tape too so
598 that it can be restored directly from the tape.
600 All the code (with the exception of formally generating and
601 saving the delete file entries) already exists in the Verify
602 Catalog command. It explicitly recognizes added/deleted files since
603 the last InitCatalog. It is more or less a "simple" matter of
604 taking that code and adapting it slightly to work for backups.
606 Comments from Martin Simmons (I think they are all covered):
607 Ok, that should cover the basics. There are few issues though:
609 - Restore will depend on the catalog. I think it is better to include the
610 extra data in the backup as well, so it can be seen by bscan and bextract.
612 - I'm not sure if it will preserve multiple hard links to the same inode. Or
613 maybe adding or removing links will cause the data to be dumped again?
615 - I'm not sure if it will handle renamed directories. Possibly it will work
616 by dumping the whole tree under a renamed directory?
618 - It remains to be seen how the backup performance of the DIR's will be
619 affected when comparing the catalog for a large filesystem.
623 How about introducing a Type = MgmtPolicy job type? That job type would
624 be responsible for scanning the Bacula environment looking for specific
625 conditions, and submitting the appropriate jobs for implementing said
629 Name = "Migration-Policy"
631 Policy Selection Job Type = Migrate
632 Scope = "<keyword> <operator> <regexp>"
633 Threshold = "<keyword> <operator> <regexp>"
634 Job Template = <template-name>
637 Where <keyword> is any legal job keyword, <operator> is a comparison
638 operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
639 appropriate regexp. I could see an argument for Scope and Threshold
640 being SQL queries if we want to support full flexibility. The
641 Migration-Policy job would then get scheduled as frequently as a site
642 felt necessary (suggested default: every 15 minutes).
647 Name = "Migration-Policy"
649 Policy Selection Job Type = Migration
651 Threshold = "Migration Selection Type = LowestUtil"
652 Job Template = "MigrationTemplate"
655 would select all pools for examination and generate a job based on
656 MigrationTemplate to automatically select the volume with the lowest
657 usage and migrate it's contents to the nextpool defined for that pool.
659 This policy abstraction would be really handy for adjusting the behavior
660 of Bacula according to site-selectable criteria (one thing that pops
661 into mind is Amanda's ability to automatically adjust backup levels
662 depending on various criteria).
668 - Add Pool/Storage override regression test.
669 - Add delete JobId to regression.
670 - Add a regression test for dbcheck.
671 - New test to add bscan to four-concurrent-jobs regression,
672 i.e. after the four-concurrent jobs zap the
673 database as is done in the bscan-test, then use bscan to
674 restore the database, do a restore and compare with the
676 - Add restore of specific JobId to regression (item 3
677 on the restore prompt)
678 - Add IPv6 to regression
679 - Add database test to regression. Test each function like delete,
682 - AntiVir can slow down backups on Win32 systems.
683 - Win32 systems with FAT32 can be much slower than NTFS for
684 more than 1000 files per directory.
688 - A HOLD command to stop all jobs from starting.
689 - A PAUSE command to pause all running jobs ==> release the

692 Media Type Read = LTO,LTO2,LTO3
693 Media Type Write = LTO2, LTO3
695 === From Carsten Menke <bootsy52@gmx.net>
697 Following is a list of what I think in the situations where I'm faced with,
698 could be a usefull enhancement to bacula, which I'm certain other users will
699 benefit from as well.
701 1. NextJob/NextJobs Directive within a Job Resource in the form of
702 NextJobs = job1,job2.
705 I currently solved the problem with running multiple jobs each after each
706 by setting the Max Wait Time for a job to 8 hours, and give
707 the jobs different Priorities. However, there scenarios where
708 1 Job is directly depending on another job, so if the former job fails,
709 the job after it needn't to be run
710 while maybe other jobs should run despite of that
713 A Backup Job and a Verify job, if the backup job fails there is no need to run
714 the verify job, as the backup job already failed. However, one may like
715 to backup the Catalog to disk despite of that the main backup job failed.
718 I see that this is related to the Event Handlers which are on the ToDo
719 list, also it is maybe a good idea to check for the return value and
720 execute different actions based on the return value
723 3. offline capability to bconsole
726 Currently I use a script which I execute within the last Job via the
727 RunAfterJob Directive, to release and eject the tape.
728 So I have to call bconsole "release=Storage-Name" and afterwards
729 mt -f /dev/nst0 eject to get the tape out.
731 If I have multiple Storage Devices, than these may not be /dev/nst0 and
732 I have to modify the script or call it with parameters etc.
733 This would actually not be needed, as everything is already defined
734 in bacula-sd.conf and if I can invoke bconsole with the
735 storage name via $1 in the script than I'm done and information is
738 4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
742 For the reason mentioned in 3. to have the ability to call a
743 script with /scripts/foobar %s and in the script use $1
744 to pass the Storage Name to bconsole
746 5. Setting Volume State within a Job Resource
749 Instead of using "Maximum Volume Jobs" in the Pool Resource,
750 I would have the possibilty to define
751 in a Job Resource that after this certain job is run, the Volume State
752 should be set to "Volume State = Used", this give more flexibility (IMHO).
754 6. Localization of Bacula Messages
757 Unfortunatley many,many people I work with don't speak english very well.
758 So if at least the Reporting messages would be localized then they
759 would understand that they have to change the tape,etc. etc.
761 I volunteer to do the german translations, and if I can convince my wife also
762 french and Morre (western african language).
764 7. OK, this is evil, probably bound to security risks and maybe not possible
765 due to the design of bacula.
767 Implementation of Backtics ( `command` ) for shell comand execution to
768 the "Label Format" Directive.
772 Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
773 Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
774 use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
775 the localized name for the day of the week appended to the
776 format string. Then I have the tape labeled automatically with weekday
777 name in the correct language.
779 - Yes, that is surely the case. I probably should turn those into Warning
780 errors. In addition, you just made me think that it might not be bad to
781 add an option to check the file size after backing up the file and
782 report if it changes. This would be done as an option because it would
785 Kern, good idea. If you do do that, mention in the output: file
786 shrunk, or file expanded, just to make it obvious to the user
787 (without having to the refer to file size), just how the file size
790 Would this option be for all file, or just one file? Or a fileset?
791 - Make output from status use html table tags for nicely
792 presenting in a browser.
793 - Can one write tapes faster with 8192 byte block sizes?
794 - Document security problems with the same password for everyone in
795 rpm and Win32 releases.
796 - Browse generations of files.
797 - I've seen an error when my catalog's File table fills up. I
798 then have to recreate the File table with a larger maximum row
799 size. Relevant information is at
800 http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
801 "Installing and Configuring MySQL" chapter should talk a bit
802 about this potential problem, and recommend a solution.
803 - For Solaris must use POSIX awk.
804 - Want speed of writing to tape while despooling.
805 - Supported autochanger:
813 Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
814 bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
815 - Add regex from http://www.pcre.org to Bacula for Win32.
816 - Use only shell tools no make in CDROM package.
817 - Include within include does it work?
818 - Implement a Pool of type Cleaning?
819 - Implement VolReadTime and VolWriteTime in SD
820 - Modify Backing up Your Database to include a bootstrap file.
821 - Think about making certain database errors fatal.
822 - Look at correcting the time jump in the scheduler for daylight
823 savings time changes.
824 - Add a "real" timer to network connections.
825 - Promote to Full = Time period
826 - Check dates entered by user for correctness (month/day/... ranges)
827 - Compress restore Volume listing by date and first file.
828 - Look at patches/bacula_db.b2z postgresql that loops during restore.
830 - Perhaps add read/write programs and/or plugins to FileSets.
831 - How to handle backing up portables ...
832 - Add some sort of guaranteed Interval for upgrading jobs.
833 - Can we write the state file after every job terminates? On Win32
834 the system crashes and the state file is not updated.
837 Documentation to do: (any release a little bit at a time)
838 - Doc to do unmount before removing magazine.
839 - Alternative to static linking "ldd prog" save all binaries listed,
840 restore them and point LD_LIBRARY_PATH to them.
841 - Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
842 - Document query file format.
843 - Add more documentation for bsr files.
844 - Document problems with Verify and pruning.
845 - Document how to use multiple databases.
846 - VXA drives have a "cleaning required"
847 indicator, but Exabyte recommends preventive cleaning after every 75
850 In this context, it should be noted that Exabyte has a command-line
851 vxatool utility available for free download. (The current version is
852 vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
853 test the drive, unload tapes, change drive settings, flash new firmware,
855 Of particular interest in this context is that vxatool <device> -i will
856 report, among other details, the time since last cleaning in tape motion
857 minutes. This information can be retrieved (and settings changed, for
858 that matter) through the generic-SCSI device even when Bacula has the
859 regular tape device locked. (Needless to say, I don't recommend
860 changing tape settings while a job is running.)
861 - Lookup HP cleaning recommendations.
862 - Lookup HP tape replacement recommendations (see trouble shooting autochanger)
863 - Document doing table repair
866 ===================================
867 - Add macro expansions in JobDefs.
868 Run Before Job = "SomeFile %{Level} %{Client}"
869 Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
870 - Use non-blocking network I/O but if no data is available, use
872 - Use gather write() for network I/O.
873 - Autorestart on crash.
874 - Add bandwidth limiting.
875 - Add acks every once and a while from the SD to keep
876 the line from timing out.
877 - When an error in input occurs and conio beeps, you can back
878 up through the prompt.
879 - Detect fixed tape block mode during positioning by looking at
880 block numbers in btape "test". Possibly adjust in Bacula.
881 - Fix list volumes to output volume retention in some other
882 units, perhaps via a directive.
883 - Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
884 with multiple priorities.
885 - If you use restore replace=never, the directory attributes for
886 non-existent directories will not be restored properly.
888 - see lzma401.zip in others directory for new compression
890 - Allow the user to select JobType for manual pruning/purging.
891 - bscan does not put first of two volumes back with all info in
893 - Implement the FreeBSD nodump flag in chflags.
894 - Figure out how to make named console messages go only to that
895 console and to the non-restricted console (new console class?).
896 - Make restricted console prompt for password if *ask* is set or
897 perhaps if password is undefined.
898 - Implement "from ISO-date/time every x hours/days/weeks/months" in
901 ==== from Marc Schoechlin
902 - the help-command should be more verbose
903 (it should explain the paramters of the different
905 -> its time-comsuming to consult the manual anytime
906 you need a special parameter
907 -> maybe its more easy to maintain this, if the
908 descriptions of that commands are outsourced to
910 - the cd-command should allow complete paths
911 i.e. cd /foo/bar/foo/bar
912 -> if a customer mails me the path to a certain file,
913 its faster to enter the specified directory
914 - if the password is not configured in bconsole.conf
915 you should be asked for it.
916 -> sometimes you like to do restore on a customer-machine
917 which shouldnt know the password for bacula.
918 -> adding the password to the file favours admins
919 to forget to remove the password after usage
921 the protection of that file is less important
922 - long-listed-output of commands should be scrollable
923 like the unix more/less-command does
924 -> if someone runs 200 and more machines, the lists could
925 be a little long and complex
926 - command-output should be shown column by column
927 to reduce scrolling and to increase clarity
929 - lsmark should list the selected files with full
931 - wildcards for selecting and file and directories would be nice
932 - any actions should be interuptable with STRG+C
933 - command-expansion would be pretty cool
935 - When the replace Never option is set, new directory permissions
936 are not restored. See bug 213. To fix this requires creating a
937 list of newly restored directories so that those directory
938 permissions *can* be restored.
939 - Add prune all command
940 - Document fact that purge can destroy a part of a restore by purging
941 one volume while others remain valid -- perhaps mark Jobs.
942 - Add multiple-media-types.txt
943 - look at mxt-changer.html
944 - Make ? do a help command (no return needed).
945 - Implement restore directory.
946 - Document streams and how to implement them.
947 - Try not to re-backup a file if a new hard link is added.
948 - Add feature to backup hard links only, but not the data.
949 - Fix stream handling to be simpler.
950 - Add Priority and Bootstrap to Run a Job.
951 - Eliminate Restore "Run Restore Job" prompt by allowing new "run command
953 - Remove View FileSet button from Run a Job dialog.
954 - Handle prompt for restore job at end of Restore command.
955 - Add display of total selected files to Restore window.
956 - Add tree pane to left of window.
957 - Add progress meter.
958 - Max wait time or max run time causes seg fault -- see runtime-bug.txt
959 - Add message to user to check for fixed block size when the forward
960 space test fails in btape.
961 - When unmarking a directory check if all files below are unmarked and
962 then remove the + flag -- in the restore tree.
963 - Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
964 - Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
965 - Revisit the question of multiple Volumes (disk) on a single device.
966 - Add a block copy option to bcopy.
967 - Finish work on Gnome restore GUI.
968 - Fix "llist jobid=xx" where no fileset or client exists.
969 - For each job type (Admin, Restore, ...) require only the really necessary
970 fields.- Pass Director resource name as an option to the Console.
971 - Add a "batch" mode to the Console (no unsolicited queries, ...).
972 - Add a .list all files in the restore tree (probably also a list all files)
973 Do both a long and short form.
974 - Allow browsing the catalog to see all versions of a file (with
975 stat data on each file).
976 - Restore attributes of directory if replace=never set but directory
978 - Use SHA1 on authentication if possible.
979 - See comtest-xxx.zip for Windows code to talk to USB.
980 - Add John's appended files:
981 Appended = { /files/server/logs/http/*log }
982 and such files would be treated as follows.On a FULL backup, they would
983 be backed up like any other file.On an INCREMENTAL backup, where a
984 previous INCREMENTAL or FULL was already in thecatalogue and the length
985 of the file wasgreater than the length of the last backup, only thedata
986 added since the last backup will be dumped.On an INCREMENTAL backup, if
987 the length of the file is less than thelength of the file with the same
988 name last backed up, the completefile is dumped.On Windows systems, with
989 creation date of files, we can be evensmarter about this and not count
990 entirely upon the length.On a restore, the full and all incrementals
991 since it will beapplied in sequence to restore the file.
992 - Check new HAVE_WIN32 open bits.
993 - Check if the tape has moved before writing.
994 - Handling removable disks -- see below:
995 - Keep track of tape use time, and report when cleaning is necessary.
996 - Add FromClient and ToClient keywords on restore command (or
997 BackupClient RestoreClient).
998 - Implement a JobSet, which groups any number of jobs. If the
999 JobSet is started, all the jobs are started together.
1000 Allow Pool, Level, and Schedule overrides.
1001 - Enhance cancel to timeout BSOCK packets after a specific delay.
1002 - Do scheduling by UTC using gmtime_r() in run_conf, scheduler, and
1003 ua_status.!!! Thanks to Alan Brown for this tip.
1004 - Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
1005 correctly for multiple simultaneous jobs.
1006 - Correct code so that FileSet MD5 is calculated for < and | filename
1008 - Implement the Media record flag that indicates that the Volume does disk
1010 - Implement VolAddr, which is used when Volume is addressed like a disk,
1011 and form it from VolFile and VolBlock.
1012 - Make multiple restore jobs for multiple media types specifying
1013 the proper storage type.
1014 - Fix fast block rejection (stored/read_record.c:118). It passes a null
1015 pointer (rec) to try_repositioning().
1016 - Look at extracting Win data from BackupRead.
1017 - Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
1018 which would take precidence over the Catalog "JobRetention".
1019 - Implement Label Format in Add and Label console commands.
1020 - Possibly up network buffers to 65K. Put on variable.
1021 - Put email tape request delays on one or more variables. User wants
1022 to cancel the job after a certain time interval. Maximum Mount Wait?
1023 - Job, Client, Device, Pool, or Volume?
1024 Is it possible to make this a directive which is *optional* in multiple
1025 resources, like Level? If so, I think I'd make it an optional directive
1026 in Job, Client, and Pool, with precedence such that Job overrides Client
1027 which in turn overrides Pool.
1029 - New Storage specifications:
1030 - Want to write to multiple storage devices simultaneously
1031 - Want to write to multiple storage devices sequentially (in one job)
1032 - Want to read/write simultaneously
1033 - Key is MediaType -- it must match
1035 Passed to SD as a sort of BSR record called Storage Specification
1039 MediaType -> Next MediaType
1041 Device -> Next Device
1043 Allow multiple Storage specifications
1051 Allow Multiple Pool specifications (note, Pool currently
1053 Allow Multiple MediaType specifications in Dir conf
1054 Allow Multiple Device specifications in Dir conf
1055 Perhaps keep this in a single SSR
1056 Tie a Volume to a specific device by using a MediaType that
1057 is contained in only one device.
1058 In SD allow Device to have Multiple MediaTypes
1060 - Ideas from Jerry Scharf:
1061 First let's point out some big pluses that bacula has for this
1063 more importantly it's active. Thank you so much for that
1064 even more important, it's not flaky
1065 it has an open access catalog, opening many possibilities
1066 it's pushing toward heterogeneous systems capability
1068 Macintosh file client
1069 macs are an interesting niche, but I fear a server is a rathole

1075 consultants on using bacula in building a disaster recovery system
1076 an integration guide
1077 or how to get at fancy things that one could do with bacula
1078 logwatch code for bacula logs (or similar)
1079 linux distro inclusion of bacula (brings good and bad, but necessary)
1080 win2k/XP server capability (icky but you asked)
1081 support for Oracle database ??
1083 - Look at adding SQL server and Exchange support for Windows.
1084 - Make dev->file and dev->block_num signed integers so that -1 can
1085 be an invalid value which happens with BSR.
1086 - Create VolAddr for disk files in place of VolFile and VolBlock. This
1087 is needed to properly specify ranges.
1088 - Add progress of files/bytes to SD and FD.
1089 - Print warning message if FileId > 4 billion
1090 - do a "messages" before the first prompt in Console
1091 - Client does not show busy during Estimate command.
1092 - Implement Console mtx commands.
1093 - Implement a Mount Command and an Unmount Command where
1094 the users could specify a system command to be performed
1095 to do the mount, after which Bacula could attempt to
1096 read the device. This is for Removeable media such as a CDROM.
1097 - Most likely, this mount command would be invoked explicitly
1098 by the user using the current Console "mount" and "unmount"
1099 commands -- the Storage Daemon would do the right thing
1100 depending on the exact nature of the device.
1101 - As with tape drives, when Bacula wanted a new removable
1102 disk mounted, it would unmount the old one, and send a message
1103 to the user, who would then use "mount" as described above
1104 once he had actually inserted the disk.
1105 - Implement dump/print label to UA
1106 - Spool to disk only when the tape is full, then when a tape is hung move
1108 - bextract is sending everything to the log file ****FIXME****
1109 - Allow multiple Storage specifications (or multiple names on
1110 a single Storage specification) in the Job record. Thus a job
1111 can be backed up to a number of storage devices.
1112 - Implement some way for the File daemon to contact the Director
1113 to start a job or pass its DHCP obtained IP number.
1114 - Implement a query tape prompt/replace feature for a console
1115 - Copy console @ code to gnome2-console
1116 - Make tree walk routines like cd, ls, ... more user friendly
1117 by handling spaces better.
1118 - Make sure that Bacula rechecks the tape after the 20 min wait.
1119 - Set IO_NOWAIT on Bacula TCP/IP packets.
1120 - Try doing a raw partition backup and restore by mounting a
1122 - From Lars Kellers:
1123 Yes, it would allow to highly automatic the request for new tapes. If a
1124 tape is empty, bacula reads the barcodes (native or simulated), and if
1125 an unused tape is found, it runs the label command with all the
1126 necessary parameters.
1128 By the way can bacula automatically "move" an empty/purged volume say
1129 in the "short" pool to the "long" pool if this pool runs out of volume
1131 - What to do about "list files job=xxx".
1132 - Look at how fuser works and /proc/PID/fd that is how Nic found the
1133 file descriptor leak in Bacula.
1134 - Implement WrapCounters in Counters.
1135 - Add heartbeat from FD to SD if hb interval expires.
1136 - Can we dynamically change FileSets?
1137 - If pool specified to label command and Label Format is specified,
1138 automatically generate the Volume name.
1139 - Why can't SQL do the filename sort for restore?
1140 - Add ExhautiveRestoreSearch
1141 - Look at the possibility of loading only the necessary
1142 data into the restore tree (i.e. do it one directory at a
1143 time as the user walks through the tree).
1144 - Possibly use the hash code if the user selects all for a restore command.
1145 - Fix "restore all" to bypass building the tree.
1146 - Prohibit backing up archive device (findlib/find_one.c:128)
1147 - Implement Release Device in the Job resource to unmount a drive.
1148 - Implement Acquire Device in the Job resource to mount a drive,
1149 be sure this works with admin jobs so that the user can get
1150 prompted to insert the correct tape. Possibly some way to say to
1151 run the job but don't save the files.
1152 - Make things like list where a file is saved case independent for
1154 - Use autochanger to handle multiple devices.
1155 - Implement a Recycle command
1156 - Start working on Base jobs.
1157 - Implement UnsavedFiles DB record.
1158 - From Phil Stracchino:
1159 It would probably be a per-client option, and would be called
1160 something like, say, "Automatically purge obsoleted jobs". What it
1161 would do is, when you successfully complete a Differential backup of a
1162 client, it would automatically purge all Incremental backups for that
1163 client that are rendered redundant by that Differential. Likewise,
1164 when a Full backup on a client completed, it would automatically purge
1165 all Differential and Incremental jobs obsoleted by that Full backup.
1166 This would let people minimize the number of tapes they're keeping on
1167 hand without having to master the art of retention times.
1168 - When doing a Backup send all attributes back to the Director, who
1169 would then figure out what files have been deleted.
1170 - Currently in mount.c:236 the SD simply creates a Volume. It should have
1171 explicit permission to do so. It should also mark the tape in error
1172 if there is an error.
1173 - Cancel waiting for Client connect in SD if FD goes away.
1175 - Implement timeout in response() when it should come quickly.
1176 - Implement a Slot priority (loaded/not loaded).
1177 - Implement "vacation" Incremental only saves.
1178 - Implement create "FileSet"?
1179 - Add prefixlinks to where or not where absolute links to FD.
1180 - Issue message to mount a new tape before the rewind.
1181 - Simplified client job initiation for portables.
1182 - If SD cannot open a drive, make it periodically retry.
1183 - Add more of the config info to the tape label.
1185 - Refine SD waiting output:
1186 Device is being positioned
1187 > Device is being positioned for append
1188 > Device is being positioned to file x
1190 - Figure out some way to estimate output size and to avoid splitting
1191 a backup across two Volumes -- this could be useful for writing CDROMs
1192 where you really prefer not to have it split -- not serious.
1193 - Have SD compute MD5 or SHA1 and compare to what FD computes.
1194 - Make VolumeToCatalog calculate an MD5 or SHA1 from the
1195 actual data on the Volume and compare it.
1196 - Implement Bacula plugins -- design API
1197 - Make bcopy read through bad tape records.
1198 - Program files (i.e. execute a program to read/write files).
1199 Pass read date of last backup, size of file last time.
1200 - Add Signature type to File DB record.
1201 - CD into subdirectory when open()ing files for backup to
1202 speed up things. Test with testfind().
1203 - Priority job to go to top of list.
1204 - Why are save/restore of device different sizes (sparse?) Yup! Fix it.
1205 - Implement some way for the Console to dynamically create a job.
1206 - Solaris -I on tar for include list
1207 - Need a verbose mode in restore, perhaps to bsr.
1208 - bscan without -v is too quiet -- perhaps show jobs.
1209 - Add code to reject whole blocks if not wanted on restore.
1210 - Check if we can increase Bacula FD priorty in Win2000
1211 - Make sure the MaxVolFiles is fully implemented in SD
1212 - Check if both CatalogFiles and UseCatalog are set to SD.
1213 - Possibly add email to Watchdog if drive is unmounted too
1214 long and a job is waiting on the drive.
1215 - After unmount, if restore job started, ask to mount.
1216 - Add UA rc and history files.
1217 - put termcap (used by console) in ./configure and
1218 allow -with-termcap-dir.
1219 - Fix Autoprune for Volumes to respect need for full save.
1220 - Compare tape to Client files (attributes, or attributes and data)
1221 - Make all database Ids 64 bit.
1222 - Allow console commands to detach or run in background.
1223 - Add SD message variables to control operator wait time
1224 - Maximum Operator Wait
1225 - Minimum Message Interval
1226 - Maximum Message Interval
1227 - Send Operator message when cannot read tape label.
1228 - Verify level=Volume (scan only), level=Data (compare of data to file).
1229 Verify level=Catalog, level=InitCatalog
1231 - Add keyword search to show command in Console.
1232 - Events : tape has more than xxx bytes.
1233 - Complete code in Bacula Resources -- this will permit
1234 reading a new config file at any time.
1235 - Handle ctl-c in Console
1236 - Implement script driven addition of File daemon to config files.
1237 - Think about how to make Bacula work better with File (non-tape) archives.
1238 - Write Unix emulator for Windows.
1239 - Put memory utilization in Status output of each daemon
1240 if full status requested or if some level of debug on.
1241 - Make database type selectable by .conf files i.e. at runtime
1242 - Set flag for uname -a. Add to Volume label.
1243 - Restore files modified after date
1244 - SET LD_RUN_PATH=$HOME/mysql/lib/mysql
1245 - Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
1246 - Timout a job or terminate if link goes down, or reopen link and query.
1247 - Concept of precious tapes (cannot be reused).
1248 - Make bcopy copy with a single tape drive.
1249 - Permit changing ownership during restore.

1263 - Autolabel should be specified by DIR instead of SD.
1265 - Add media capacity
1266 - AutoScan (check checksum of tape)
1267 - Format command = "format /dev/nst0"
1271 - Seek resolution (usually corresponds to buffer size)
1272 - EODErrorCode=ENOSPC or code
1273 - Partial Read error code
1274 - Partial write error code
1275 - Nonformatted read error
1276 - Nonformatted write error
1277 - WriteProtected error
1281 - IgnoreCloseErrors=yes
1291 - FD sends unsaved file list to Director at end of job (see
1293 - File daemon should build list of files skipped, and then
1294 at end of save retry and report any errors.
1295 - Write a Storage daemon that uses pipes and
1296 standard Unix programs to write to the tape.
1298 - Need something that monitors the JCR queue and
1299 times out jobs by asking the deamons where they are.
1300 - Enhance Jmsg code to permit buffering and saving to disk.
1301 - device driver = "xxxx" for drives.
1302 - Verify from Volume
1303 - Ensure that /dev/null works
1304 - Need report class for messages. Perhaps
1305 report resource where report=group of messages
1306 - enhance scan_attrib and rename scan_jobtype, and
1307 fill in code for "since" option
1308 - Director needs a time after which the report status is sent
1309 anyway -- or better yet, a retry time for the job.
1310 - Don't reschedule a job if previous incarnation is still running.
1311 - Some way to automatically backup everything is needed????
1312 - Need a structure for pending actions:
1314 - termination status (part of buffered msgs?)
1316 Read, Write, Clean, Delete
1317 - Login to Bacula; Bacula users with different permissions:
1318 owner, group, user, quotas
1319 - Store info on each file system type (probably in the job header on tape.
1320 This could be the output of df; or perhaps some sort of /etc/mtab record.
1322 ========= ideas ===============
1323 From: "Jerry K. Schieffer" <jerry@skylinetechnology.com>
1324 To: <kern@sibbald.com>
1325 Subject: RE: [Bacula-users] future large programming jobs
1326 Date: Thu, 26 Feb 2004 11:34:54 -0600
1328 I noticed the subject thread and thought I would offer the following
1329 merely as sources of ideas, i.e. something to think about, not even as
1330 strong as a request. In my former life (before retiring) I often
1331 dealt with backups and storage management issues/products as a
1332 developer and as a consultant. I am currently migrating my personal
1333 network from amanda to bacula specifically because of the ability to
1334 cross media boundaries during storing backups.
1335 Are you familiar with the commercial product called ADSM (I think IBM
1336 now sells it under the Tivoli label)? It has a couple of interesting
1337 ideas that may apply to the following topics.
1339 1. Migration: Consider that when you need to restore a system, there
1340 may be pressure to hurry. If all the information for a single client
1341 can eventually end up on the same media (and in chronological order),
1342 the restore is facillitated by not having to search past information
1343 from other clients. ADSM has the concept of "client affinity" that
1344 may be associated with it's storage pools. It seems to me that this
1345 concept (as an optional feature) might fit in your architecture for
1348 ADSM also has the concept of defining one or more storage pools as
1349 "copy pools" (almost mirrors, but only in the sense of contents).
1350 These pools provide the ability to have duplicte data stored both
1351 onsite and offsite. The copy process can be scheduled to be handled
1352 by their storage manager during periods when there is no backup
1353 activity. Again, the migration process might be a place to consider
1354 implementing something like this.
1357 > It strikes me that it would be very nice to be able to do things
1359 > have the Job(s) backing up the machines run, and once they have all

1365 > mechanism described below would probably make it very easy.
1367 This is the goal. In the first step (before events), you simply
1369 the Migration to tape later.
1371 2. Base jobs: In ADSM, each copy of each stored file is tracked in
1372 the database. Once a file (unique by path and metadata such as dates,
1373 size, ownership, etc.) is in a copy pool, no more copies are made. In
1374 other words, when you start ADSM, it begins like your concept of a
1375 base job. After that it is in the "incremental" mode. You can
1376 configure the number of "generations" of files to be retained, plus a
1377 retention date after which even old generations are purged. The
1378 database tracks the contents of media and projects the percentage of
1379 each volume that is valid. When the valid content of a volume drops
1380 below a configured percentage, the valid data are migrated to another
1381 volume and the old volume is marked as empty. Note, this requires
1382 ADSM to have an idea of the contents of a client, i.e. marking the
1383 database when an existing file was deleted, but this would solve your
1384 issue of restoring a client without restoring deleted files.
1386 This is pretty far from what bacula now does, but if you are going to
1387 rip things up for Base jobs,.....
1388 Also, the benefits of this are huge for very large shops, especially
1389 with media robots, but are a pain for shops with manual media
1393 > Base jobs sound pretty useful, but I'm not dying for them.
1395 Nobody is dying for them, but when you see what it does, you will die
1398 3. Restoring deleted files: Since I think my comments in (2) above
1399 have low probability of implementation, I'll also suggest that you
1400 could approach the issue of deleted files by a mechanism of having the
1401 fd report to the dir, a list of all files on the client for every
1402 backup job. The dir could note in the database entry for each file
1403 the date that the file was seen. Then if a restore as of date X takes
1404 place, only files that exist from before X until after X would be
1405 restored. Probably the major cost here is the extra date container in
1406 each row of the files table.
1408 Thanks for "listening". I hope some of this helps. If you want to
1409 contact me, please send me an email - I read some but not all of the
1410 mailing list traffic and might miss a reply there.
1412 Please accept my compliments for bacula. It is doing a great job for
1413 me!! I sympathize with you in the need to wrestle with excelence in
1414 execution vs. excelence in feature inclusion.
1419 ==============================
1422 - Design at hierarchial storage for Bacula. Migration and Clone.
1423 - Implement FSM (File System Modules).
1424 - Audit M_ error codes to ensure they are correct and consistent.
1425 - Add variable break characters to lex analyzer.
1426 Either a bit mask or a string of chars so that
1427 the caller can change the break characters.
1428 - Make a single T_BREAK to replace T_COMMA, etc.
1429 - Ensure that File daemon and Storage daemon can
1430 continue a save if the Director goes down (this
1431 is NOT currently the case). Must detect socket error,
1432 buffer messages for later.
1433 - Enhance time/duration input to allow multiple qualifiers e.g. 3d2h
1434 - Add ability to backup to two Storage devices (two SD sessions) at
1435 the same time -- e.g. onsite, offsite.
1436 - Add the ability to consolidate old backup sets (basically do a restore
1437 to tape and appropriately update the catalog). Compress Volume sets.
1438 Might need to spool via file is only one drive is available.
1439 - Compress or consolidate Volumes of old possibly deleted files. Perhaps
1440 someway to do so with every volume that has less than x% valid
1444 Migration: Move a backup from one Volume to another
1445 Clone: Copy a backup -- two Volumes
1448 ======================================================
1450 It is somewhat like a Full save becomes an incremental since
1451 the Base job (or jobs) plus other non-base files.
1453 - A Base backup is same as Full backup, just different type.
1454 - New BaseFiles table that contains:
1456 BaseJobId - Base JobId referenced for this FileId (needed ???)
1457 JobId - JobId currently running
1458 FileId - File not backed up, exists in Base Job
1459 FileIndex - FileIndex from Base Job.
1460 i.e. for each base file that exists but is not saved because
1461 it has not changed, the File daemon sends the JobId, BaseId,
1462 FileId, FileIndex back to the Director who creates the DB entry.
1463 - To initiate a Base save, the Director sends the FD
1464 the FileId, and full filename for each file in the Base.
1465 - When the FD finds a Base file, he requests the Director to
1466 send him the full File entry (stat packet plus MD5), or
1467 conversely, the FD sends it to the Director and the Director
1468 says yes or no. This can be quite rapid if the FileId is kept
1469 by the FD for each Base Filename.
1470 - It is probably better to have the comparison done by the FD
1471 despite the fact that the File entry must be sent across the
1473 - An alternative would be to send the FD the whole File entry
1474 from the start. The disadvantage is that it requires a lot of
1475 space. The advantage is that it requires less communications
1477 - The Job record must be updated to indicate that one or more
1479 - At end of Job, FD returns:
1480 1. Count of base files/bytes not written to tape (i.e. matches)
1481 2. Count of base file that were saved i.e. had changed.
1482 - No tape record would be written for a Base file that matches, in the
1483 same way that no tape record is written for Incremental jobs where
1484 the file is not saved because it is unchanged.
1485 - On a restore, all the Base file records must explicitly be
1486 found from the BaseFile tape. I.e. for each Full save that is marked
1487 to have one or more Base Jobs, search the BaseFile for all occurrences
1489 - An optimization might be to make the BaseFile have:
1495 This would avoid the need to explicitly fetch each File record for
1496 the Base job. The Base Job record will be fetched to get the
1497 VolSessionId and VolSessionTime.
1498 =========================================================
1501 ==========================================================
1503 For each Incremental job that is run, there may be files that
1504 were found but not saved because they were locked (this applies
1505 only to Windows). Such a system could send back to the Director
1506 a list of Unsaved files.
1508 - New UnSavedFiles table that contains:
1512 - Then in the next Incremental job, the list of Unsaved Files will be
1513 feed to the FD, who will ensure that they are explicitly chosen even
1514 if standard date/time check would not have selected them.
1515 =============================================================

1556 (just to verify it remembers where it came from, however it can be

1559 There needs to be a table of drive # to devices somewhere - If there are
1560 multiple changers or drives there may not be a 1:1 correspondance between
1561 changer drive number and system device name - and depending on the way the
1562 drives are hooked up to scsi busses, they may not be linearly numbered
1563 from an offset point either.something like
1565 Autochanger drives = 2
1566 Autochanger drive 0 = /dev/nst1
1567 Autochanger drive 1 = /dev/nst2
1568 IMHO, it would be _safest_ to use explicit mtx unload commands at all
1569 times, not just for multidrive changers. For a 1 drive changer, that's
1575 MTX's manpage (1.2.15):
1576 unload [<slotnum>] [ <drivenum> ]
1577 Unloads media from drive <drivenum> into slot
1578 <slotnum>. If <drivenum> is omitted, defaults to
1579 drive 0 (as do all commands). If <slotnum> is
1580 omitted, defaults to the slot that the drive was
1581 loaded from. Note that there's currently no way
1582 to say 'unload drive 1's media to the slot it
1583 came from', other than to explicitly use that
1584 slot number as the destination.AB

1622 Handling removable disks
1624 From: Karl Cunningham <karlc@keckec.com>
1626 My backups are only to hard disk these days, in removable bays. This is my
1627 idea of how a backup to hard disk would work more smoothly. Some of these
1628 things Bacula does already, but I mention them for completeness. If others
1629 have better ways to do this, I'd like to hear about it.
1631 1. Accommodate several disks, rotated similar to how tapes are. Identified
1632 by partition volume ID or perhaps by the name of a subdirectory.
1633 2. Abort & notify the admin if the wrong disk is in the bay.
1634 3. Write backups to different subdirectories for each machine to be backed
1636 4. Volumes (files) get created as needed in the proper subdirectory, one
1638 5. When a disk is recycled, remove or zero all old backup files. This is
1639 important as the disk being recycled may be close to full. This may be
1640 better done manually since the backup files for many machines may be
1641 scattered in many subdirectories.
1646 - Make sure that all do_prompt() calls in Dir check for
1647 -1 (error) and -2 (cancel) returns.
1648 - Fix foreach_jcr() to have free_jcr() inside next().
1649 jcr=jcr_walk_start();
1650 for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
1653 - A Volume taken from Scratch should take on the retention period
1655 - Correct doc for Maximum Changer Wait (and others) accepting only
1657 - Implement status that shows why a job is being held in reserve, or
1658 rather why none of the drives are suitable.
1659 - Implement a way to disable a drive (so you can use the second
1660 drive of an autochanger, and the first one will not be used or
1662 - Make sure Maximum Volumes is respected in Pools when adding
1663 Volumes (e.g. when pulling a Scratch volume).
1664 - Keep same dcr when switching device ...
1665 - Implement code that makes the Dir aware that a drive is an
1666 autochanger (so the user doesn't need to use the Autochanger = yes
1668 - Make catalog respect ACL.
1669 - Add recycle count to Media record.
1670 - Add initial write date to Media record.
1671 - Fix store_yesno to be store_bitmask.

1695 and verify that other buffers cannot overrun.
1696 - Implement VolumeState as discussed with Arno.
1697 - Add LocationId to update volume
1705 - Add Comment to Media record
1706 - Fix auth compatibility with 1.38
1707 - Update dbcheck to include Log table
