Kern's ToDo List
- 12 May 2007
+ 02 May 2008
Document:
- 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:
-- Implement update jobid=
-- Mention Eric and Marc's work + Marc's doc.
-- Add TLS to bat
+================
+- 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.
+- Implement Bacula plugins -- design API
+- 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.
+=== 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.
-- Add Catalog = to Pool resource so that pools will exist
- in only one catalog -- currently Pools are "global".
- Look at sg_logs -a /dev/sg0 for getting soft errors.
- btape "test" command with Offline on Unmount = yes
02-Feb 11:00 btape: Fatal Error because: Bacula interrupted by signal 11: Segmentation violation
Kaboom! btape, btape got signal 11. Attempting traceback.
-- Ensure that moving a purged Volume in ua_purge.c to the RecyclePool
- does the right thing.
-- Why doesn't @"xxx abc" work in a conf file?
+- 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.
and possibly changing the blobs into varchar.
- Ensure that the SD re-reads the Media record if the JobFiles
does not match -- it may have been updated by another job.
-- Look at moving the Storage directive from the Job to the
- Pool in the default conf files.
- Doc items
- Test Volume compatibility between machine architectures
- Encryption documentation
- Wrong jobbytes with query 12 (todo)
-- bacula-1.38.2-ssl.patch
- Bare-metal recovery Windows (todo)

immutable flag must be removed prior to trying to link it.
-- Implement Python event for backing up/restoring a file.
- Change dbcheck to tell users to use native tools for fixing
broken databases, and to ensure they have the proper indexes.
- add udev rules for Bacula devices.

- Article:
-- It appears to me that you have run into some sort of race
- condition where two threads want to use the same Volume and they
- were both given access. Normally that is no problem. However,
- one thread wanted the particular Volume in drive 0, but it was
- loaded into drive 1 so it decided to unload it from drive 1 and
- then loaded it into drive 0, while the second thread went on
- thinking that the Volume could be used in drive 1 not realizing
- that in between time, it was loaded in drive 0.
- I'll look at the code to see if there is some way we can avoid
- this kind of problem. Probably the best solution is to make the
- first thread simply start using the Volume in drive 1 rather than
- transferring it to drive 0.
-- Fix re-read of last block to check if job has actually written
- a block, and check if block was written by a different job
- (i.e. multiple simultaneous jobs writing).

+- Possibly allow SD to spool even if a tape is not mounted.
- Figure out how to configure query.sql. Suggestion to use m4:
== changequote.m4 ===
changequote(`[',`]')dnl
The problem is that it requires m4, which is not present on all machines
at ./configure time.
-- Given all the problems with FIFOs, I think the solution is to do something a
- little different, though I will look at the code and see if there is not some
- simple solution (i.e. some bug that was introduced). What might be a better
- solution would be to use a FIFO as a sort of "key" to tell Bacula to read and
- write data to a program rather than the FIFO. For example, suppose you
- create a FIFO named:
-
- /home/kern/my-fifo
-
- Then, I could imagine if you backup and restore this file with a direct
- reference as is currently done for fifos, instead, during backup Bacula will
- execute:
-
- /home/kern/my-fifo.backup
-
- and read the data that my-fifo.backup writes to stdout. For restore, Bacula
- will execute:
-
- /home/kern/my-fifo.restore
-
- and send the data backed up to stdout. These programs can either be an
- executable or a shell script and they need only read/write to stdin/stdout.
-
- I think this would give a lot of flexibility to the user without making any
- significant changes to Bacula.

==== SQL
# get null file
- Look into replacing autotools with cmake
http://www.cmake.org/HTML/Index.html
-=== Migration from David ===
-What I'd like to see:
-
-Job {
- Name = "<poolname>-migrate"
- Type = Migrate
- Messages = Standard
- Pool = Default
- Migration Selection Type = LowestUtil | OldestVol | PoolOccupancy |
-Client | PoolResidence | Volume | JobName | SQLquery
- Migration Selection Pattern = "regexp"
- Next Pool = <override>
-}
-
-There should be no need for a Level (migration is always Full, since you
-don't calculate differential/incremental differences for migration),
-Storage should be determined by the volume types in the pool, and Client
-is really a selection issue. Migration should always occur to the
-NextPool defined in the pool definition. If no nextpool is defined, the
-job should end with a reason of "no place to go". If Next Pool statement
-is present, we override the check in the pool definition and use the
-pool specified.
-
-Here's how I'd define Migration Selection Types:
-
-With Regexes:
-Client -- Migrate data from selected client only. Migration Selection
-Pattern regexp provides pattern to select client names, eg ^FS00* makes
-all client names starting with FS00 eligible for migration.
-
-Jobname -- Migration all jobs matching name. Migration Selection Pattern
-regexp provides pattern to select jobnames existing in pool.
-
-Volume -- Migrate all data on specified volumes. Migration Selection
-Pattern regexp provides selection criteria for volumes to be migrated.
-Volumes must exist in pool to be eligible for migration.
-
-
-With Regex optional:
-LowestUtil -- Identify the volume in the pool with the least data on it
-and empty it. No Migration Selection Pattern required.
-
-OldestVol -- Identify the LRU volume with data written, and empty it. No
-Migration Selection Pattern required.
-
-PoolOccupancy -- if pool occupancy exceeds <highmig>, migrate volumes
-(starting with most full volumes) until pool occupancy drops below
-<lowmig>. Pool highmig and lowmig values are in pool definition, no
-Migration Selection Pattern required.
-
-
-No regex:
-SQLQuery -- Migrate all jobuids returned by the supplied SQL query.
-Migration Selection Pattern contains SQL query to execute; should return
-a list of 1 or more jobuids to migrate.
-
-PoolResidence -- Migrate data sitting in pool for longer than
-PoolResidence value in pool definition. Migration Selection Pattern
-optional; if specified, override value in pool definition (value in
-minutes).
-
-
-[ possibly a Python event -- kes ]
-===
- Mount on an Autochanger with no tape in the drive causes:
Automatically selected Storage: LTO-changer
Enter autochanger drive[0]: 0
("D","Diff"),
("I","Inc");
- Show files/second in client status output.
-- 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.
-- New directive "Delete purged Volumes"
- new pool XXX with ScratchPoolId = MyScratchPool's PoolId and
let it fill itself, and RecyclePoolId = XXX's PoolId so I can
see if it become stable and I just have to supervise
MyScratchPool
- If I want to remove this pool, I set RecyclePoolId = MyScratchPool's
PoolId, and when it is empty remove it.
-- Figure out how to recycle Scratch volumes back to the Scratch Pool.
- Add Volume=SCRTCH
- Allow Check Labels to be used with Bacula labels.
- "Resuming" a failed backup (lost line for example) by using the
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.
- 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.
-=== 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/new files ====
-- To mark files as deleted, run essentially a Verify to disk, and
- when a file is found missing (MarkId != JobId), then create
- a new File record with FileIndex == -1. This could be done
- by the FD at the same time as the backup.
-
- My "trick" for keeping track of deletions is the following.
- Assuming the user turns on this option, after all the files
- have been backed up, but before the job has terminated, the
- 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. This
- either transmitted to the FD or simultaneously computed in
- the FD, so that the FD can put a record on the tape that
- indicates that the file has been deleted at this point.
- A delete file entry could potentially be one with a FileIndex
- of 0 or perhaps -1 (need to check if FileIndex is used for
- some other thing as many of the Bacula fields are "overloaded"
- in the SD).
-
- During a restore, any file initially picked up by some
- backup (Full, ...) then subsequently having a File entry
- 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.
-
- All the code (with the exception of formally generating and
- saving the delete file entries) already exists in the Verify
- Catalog command. It explicitly recognizes added/deleted files since
- the last InitCatalog. It is more or less a "simple" matter of
- taking that code and adapting it slightly to work for backups.
-
- Comments from Martin Simmons (I think they are all covered):
- Ok, that should cover the basics. There are few issues though:
-
- - 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:
format string. Then I have the tape labeled automatically with weekday
name in the correct language.
==========
-- 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
- 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
- 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.
-- 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 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
- What to do about "list files job=xxx".
- Look at how fuser works and /proc/PID/fd that is how Nic found the
file descriptor leak in Bacula.
-- Implement WrapCounters in Counters.
-- Add heartbeat from FD to SD if hb interval expires.
- Can we dynamically change FileSets?
- If pool specified to label command and Label Format is specified,
automatically generate the Volume name.
-- Why can't SQL do the filename sort for restore?
- 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.
-- Use autochanger to handle multiple devices.
- Implement a Recycle command
- 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
- 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.
- Implement script driven addition of File daemon to config files.
- Think about how to make Bacula work better with File (non-tape) archives.
- Write Unix emulator for Windows.
-- Put memory utilization in Status output of each daemon
- if full status requested or if some level of debug on.
- 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?)
=====
-- FD sends unsaved file list to Director at end of job (see
- RFC below).
-- File daemon should build list of files skipped, and then
- at end of save retry and report any errors.
- Write a Storage daemon that uses pipes and
standard Unix programs to write to the tape.
See afbackup.
- Need something that monitors the JCR queue and
times out jobs by asking the deamons where they are.
- Enhance Jmsg code to permit buffering and saving to disk.
-- device driver = "xxxx" for drives.
- Verify from Volume
-- Ensure that /dev/null works
- Need report class for messages. Perhaps
report resource where report=group of messages
- enhance scan_attrib and rename scan_jobtype, and
Nobody is dying for them, but when you see what it does, you will die
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
-
======================================================
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.

- Unloading Data Transfer Element into Storage Element 15...done

- (just to verify it remembers where it came from, however it can be
- overrriden with mtx unload {slotnumber} to go to any storage slot.)
- Configuration wise:
- There needs to be a table of drive # to devices somewhere - If there are
- multiple changers or drives there may not be a 1:1 correspondance between
- changer drive number and system device name - and depending on the way the
- drives are hooked up to scsi busses, they may not be linearly numbered
- from an offset point either.something like
-
- Autochanger drives = 2
- Autochanger drive 0 = /dev/nst1
- Autochanger drive 1 = /dev/nst2
- IMHO, it would be _safest_ to use explicit mtx unload commands at all
- times, not just for multidrive changers. For a 1 drive changer, that's
- just:
-
- mtx load xx 0
- mtx unload xx 0
-
- MTX's manpage (1.2.15):
- unload [<slotnum>] [ <drivenum> ]
- Unloads media from drive <drivenum> into slot
- <slotnum>. If <drivenum> is omitted, defaults to
- drive 0 (as do all commands). If <slotnum> is
- omitted, defaults to the slot that the drive was
- loaded from. Note that there's currently no way
- to say 'unload drive 1's media to the slot it
- came from', other than to explicitly use that
- slot number as the destination.AB

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