-Major development:
-Project Developer
-======= =========
Document:
+- This patch will give Bacula the option to specify files in
+ FileSets which can be dropped in directories which are Included
+ which will cause that directory not the be backed up.
+
+ For example, my FileSet contains:
+ # List of files to be backed up
+ FileSet {
+ Name = "Remote Specified1"
+ Include {
+ Options {
+ signature = MD5
+ }
+ File = "\\</etc/bacula-include"
+ IgnoreDir = .notthisone
+ }
+ Exclude {
+ File = "\\</etc/bacula-exclude"
+ }
+ }
+
+ And /etc/bacula-include contains:
+
+ /home
+
+ But in /home, there are hundreds of directories of users and some
+ people want to indicate that they don't want to have certain
+ directories backed-up:
+
+ /home/edwin/www/cache
+ /home/edwin/temp
+
+ So I can put them in /etc/bacula-exclude, but that is a system
+ file and not editable for mortal users. To make it possible for
+ users to make it clear to the system that certain directories
+ don't need to be backed up, they now can create file called
+ .notthisone:
+
+ /home/edwin/www/cache/.notthisone
+ /home/edwin/temp/.notthisone
+
+ so that the backup system will be clear of rubbish like stuff in
+ these two directories but still that I as administrator of the
+ system don't have to be involved in it.
+- !!! 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.
- 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:
-- Check if gnome-console works with TLS.
+================
+- 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.
+- Check for FD compatibility -- eg .nobackup ...
+- Re-check new dcr->reserved_volume
+- Softlinks that point to non-existent file are not restored in restore all,
+ but are restored if the file is individually selected. BUG!
+- Doc Duplicate Jobs.
+- 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
+- Eliminate: /var is a different filesystem. Will not descend from / into /var
+- 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.
-- Look at moving the Storage directive from the Job to the
- Pool in the default conf files.
-- Test FIFO backup/restore -- make regression
- 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)

Low priority:
-- 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.
-- After pruning, check to see if the Volume retention period has
- expired.
-- Check to see if jcr->stime is lost during rescheduling of
- jobs in jobq.c

+- Possibly allow SD to spool even if a tape is not mounted.
- 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).
The problem is that it requires m4, which is not present on all machines
at ./configure time.
-- Get Perl replacement for bregex.c

little different, though I will look at the code and see if there is not some

-=== 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
If this is not a blank tape, try unmounting and remounting the Volume.
- http://www.dwheeler.com/essays/commercial-floss.html
-- Add VolumeState (enable, disable, archive)
- Add VolumeLock to prevent all but lock holder (SD) from updating
the Volume data (with the exception of VolumeState).
- The btape fill command does not seem to use the Autochanger
- What happens when you rename a Disk Volume?
- Job retention period in a Pool (and hence Volume). The job would
then be migrated.
-- Detect resource deadlock in Migrate when same job wants to read
- and write the same device.
-- Queue warning/error messages during restore so that they
- are reported at the end of the report rather than being
- hidden in the file listing ...
- Look at -D_FORTIFY_SOURCE=2
- Add Win32 FileSet definition somewhere
- Look at fixing restore status stats in SD.
-- Make selection of Database used in restore correspond to
- client.
- Look at using ioctl(FIMAP) and FIGETBSZ for sparse files.
http://www.informatik.uni-frankfurt.de/~loizides/reiserfs/fibmap.html
- Implement a mode that says when a hard read error is
("F","Full"),
("D","Diff"),
("I","Inc");
-- Add ACL to restore only to original location.
- 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.
- It remains to be seen how the backup performance of the DIR's will be
affected when comparing the catalog for a large filesystem.
+ 1. Use the current Director in-memory tree code (very fast), but currently in
+ memory. It probably could be paged.
+
+ 2. Use some DB such as Berkeley DB or SQLite. SQLite is already compiled and
+ built for Win32, and it is something we could compile into the program.
+
+ 3. Implement our own custom DB code.
+
+ Note, by appropriate use of Directives in the Director, we can dynamically
+ decide if the work is done in the Director or in the FD, and we can even
+ allow the user to choose.
+
+=== most recent accurate file backup/restore ===
+ Here is a sketch (i.e. more details must be filled in later) that I recently
+ made of an algorithm for doing Accurate Backup.
+
+ 1. Dir informs FD that it is doing an Accurate backup and lookup done by
+ Director.
+
+ 2. FD passes through the file system doing a normal backup based on normal
+ conditions, recording the names of all files and their attributes, and
+ indicating which files were backed up. This is very similar to what Verify
+ does.
+
+ 3. The Director receives the two lists of files at the end of the FD backup.
+ One, files backed up, and one files not backed up. It then looks up all the
+ files not backed up (using Verify style code).
+
+ 4. The Dir sends the FD a list of:
+ a. Additional files to backup (based on user specified criteria, name, size
+ inode date, hash, ...).
+ b. Files to delete.
+
+ 5. Dir deletes list of file not backed up.
+
+ 6. FD backs up additional files generates a list of those backed up and sends
+ it to the Director, which adds it to the list of files backed up. The list
+ is now complete and current.
+
+ 7. The FD generates delete records for all the files that were deleted and
+ sends to the SD.
+
+ 8. The Dir deletes the previous CurrentBackup list, and then does a
+ transaction insert of the new list that it has.
+
+ 9. The rest works as before ...
+
+ That is it.
+
+ Two new tables needed.
+ 1. CurrentBackupId table that contains Client, JobName, FileSet, and a unique
+ BackupId. This is created during a Full save, and the BackupId can be set to
+ the JobId of the Full save. It will remain the same until another Full
+ backup is done. That is when new records are added during a Differential or
+ Incremental, they must use the same BackupId.
+
+ 2. CurrentBackup table that contains essentially a File record (less a number
+ of fields, but with a few extra fields) -- e.g. a flag that the File was
+ backed up by a Full save (this permits doing a Differential). The unique
+ BackupId allows us to look up the CurrentBackup for a particular Client,
+ Jobname, FileSet using that unique BackupId as the key, so this table must be
+ indexed by the BackupId.
+
+ Note any time a file is saved by the FD other than during a Full save, the
+ Full save flag is cleared. When doing a Differential backup, if a file has
+ the Full save flag set, it is skipped, otherwise it is backed up. For an
+ Incremental backup, we check to see if the file has changed since the last
+ time we backed it up.
+
+ Deleted files should have FileIndex == 0

====
From David:
How about introducing a Type = MgmtPolicy job type? That job type would
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?
block numbers in btape "test". Possibly adjust in Bacula.
- Fix list volumes to output volume retention in some other
units, perhaps via a directive.
-- If opening a tape in read/write mode fails attempt to open
- it in read-only mode, and mark the tape for read only.
- Allow Simultaneous Priorities = yes => run up to Max concurrent jobs even
with multiple priorities.
- If you use restore replace=never, the directory attributes for
- see lzma401.zip in others directory for new compression
algorithm/library.
-- Minimal autochanger handling in Bacula and in btape.
-- Look into how tar does not save sockets and the possiblity of
- not saving them in Bacula (Martin Simmons reported this).
-- Fix restore jobs so that multiple jobs can run if they
- are not using the same tape(s).
- Allow the user to select JobType for manual pruning/purging.
- bscan does not put first of two volumes back with all info in
bscan-test.
-> 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
to start a job or pass its DHCP obtained IP number.
- Implement a query tape prompt/replace feature for a console
- Copy console @ code to gnome2-console
-- Make AES the only encryption algorithm see
- http://csrc.nist.gov/CryptoToolkit/aes/). It's
- an officially adopted standard, has survived peer
- review, and provides keys up to 256 bits.
-- Take a careful look at SetACL http://setacl.sourceforge.net
-- Make tree walk routines like cd, ls, ... more user friendly
- by handling spaces better.
- Make sure that Bacula rechecks the tape after the 20 min wait.
- 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
file descriptor leak in Bacula.
- Implement WrapCounters in Counters.
run the job but don't save the files.
- Make things like list where a file is saved case independent for
Windows.
-- Implement migrate
- Use autochanger to handle multiple devices.
-- On Windows with very long path names, it may be impossible to create
- a file (and thus restore it) because the total length is too long.
- We must cd into the directory then create the file without the
- full path name.
- Implement a Recycle command
-- Test a second language e.g. french.
- Start working on Base jobs.
- Implement UnsavedFiles DB record.
- From Phil Stracchino:
- If SD cannot open a drive, make it periodically retry.
- Add more of the config info to the tape label.
-- If tape is marked read-only, then try opening it read-only rather than
- failing, and remember that it cannot be written.
- Refine SD waiting output:
Device is being positioned
> Device is being positioned for append
- 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.
- Compare tape to Client files (attributes, or attributes and data)
- Make all database Ids 64 bit.
- Allow console commands to detach or run in background.
-- Fix status delay on storage daemon during rewind.
- Add SD message variables to control operator wait time
- Maximum Operator Wait
- Minimum Message Interval
- 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
=========================================================
-==========================================================
- 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.

=====
Multiple drive autochanger data: see Alan Brown
=== Done
-- Make sure that all do_prompt() calls in Dir check for
- -1 (error) and -2 (cancel) returns.
-- Fix foreach_jcr() to have free_jcr() inside next().
- jcr=jcr_walk_start();
- for ( ; jcr; (jcr=jcr_walk_next(jcr)) )
- ...
- jcr_walk_end(jcr);
-- A Volume taken from Scratch should take on the retention period
- of the new pool.
-- Correct doc for Maximum Changer Wait (and others) accepting only
- integers.
-- Implement status that shows why a job is being held in reserve, or
- rather why none of the drives are suitable.
-- Implement a way to disable a drive (so you can use the second
- drive of an autochanger, and the first one will not be used or
- even defined).
-- Make sure Maximum Volumes is respected in Pools when adding
- Volumes (e.g. when pulling a Scratch volume).
-- Keep same dcr when switching device ...
-- Implement code that makes the Dir aware that a drive is an
- autochanger (so the user doesn't need to use the Autochanger = yes
- directive).
-- Make catalog respect ACL.
-- Add recycle count to Media record.
-- Add initial write date to Media record.
-- Fix store_yesno to be store_bitmask.

+=== Duplicate jobs ===
+- Done, but implemented somewhat differently than described below!!!
+
+ hese apply only to backup jobs.
+
+ 1. Allow Duplicate Jobs = Yes | No | Higher (Yes)
+
+ 2. Duplicate Job Interval = <time-interval> (0)
+
+ The defaults are in parenthesis and would produce the same behavior as today.
+
+ If Allow Duplicate Jobs is set to No, then any job starting while a job of the
+ same name is running will be canceled.
+
+ If Allow Duplicate Jobs is set to Higher, then any job starting with the same
+ or lower level will be canceled, but any job with a Higher level will start.
+ The Levels are from High to Low: Full, Differential, Incremental
+
+ Finally, if you have Duplicate Job Interval set to a non-zero value, any job
+ of the same name which starts <time-interval> after a previous job of the
+ same name would run, any one that starts within <time-interval> would be
+ subject to the above rules. Another way of looking at it is that the Allow
+ Duplicate Jobs directive will only apply after <time-interval> of when the
+ previous job finished (i.e. it is the minimum interval between jobs).
+
+ So in summary:
+
+ Allow Duplicate Jobs = Yes | No | HigherLevel | CancelLowerLevel (Yes)
+
+ Where HigherLevel cancels any waiting job but not any running job.
+ Where CancelLowerLevel is same as HigherLevel but cancels any running job or
+ waiting job.
+
+ Duplicate Job Proximity = <time-interval> (0)
+
+ My suggestion was to define it as the minimum guard time between
+ executions of a specific job -- ie, if a job was scheduled within Job
+ Proximity number of seconds, it would be considered a duplicate and
+ consolidated.
+
+ Skip = Do not allow two or more jobs with the same name to run
+ simultaneously within the proximity interval. The second and subsequent
+ jobs are skipped without further processing (other than to note the job
+ and exit immediately), and are not considered errors.
+
+ Fail = The second and subsequent jobs that attempt to run during the
+ proximity interval are cancelled and treated as error-terminated jobs.
+
+ Promote = If a job is running, and a second/subsequent job of higher
+ level attempts to start, the running job is promoted to the higher level
+ of processing using the resources already allocated, and the subsequent
+ job is treated as in Skip above.
+
+
+DuplicateJobs {
+ Name = "xxx"
+ Description = "xxx"
+ Allow = yes|no (no = default)
+
+ AllowHigherLevel = yes|no (no)
+
+ AllowLowerLevel = yes|no (no)
+
+ AllowSameLevel = yes|no
+
+ Cancel = Running | New (no)
+
+ CancelledStatus = Fail | Skip (fail)
+
+ Job Proximity = <time-interval> (0)
+ My suggestion was to define it as the minimum guard time between
+ executions of a specific job -- ie, if a job was scheduled within Job
+ Proximity number of seconds, it would be considered a duplicate and
+ consolidated.
+
+}
