Why: Currently, you either have to...
- a) laboriously type in a date that is greater than the date of the backup that
- you want and is less than the subsequent backup (bacula then figures out the
- dependent jobs), or
- b) manually figure out all the JobIds that you want and laboriously type them
- all in.
- It would be extremely useful (in a programmatical sense, as well as for humans)
- to be able to just give it a single JobId and let bacula do the hard work (work
- that it already knows how to do).
-
- Notes (Kern): I think this should either be modified to have Bacula print
- a list of dates that the user can choose from as is done in bwx-console and
- bat or the name of this command must be carefully chosen so that the user
- clearly understands that the JobId is being used to specify what Job and the
- date to which he wishes the restore to happen.

+Item n: Command that releases all drives in an autochanger
+ Origin: Blake Dunlap (blake@nxs.net)
+ Date: 10/07/2009
+ Status: Request
+
+ What: It would be nice if there was a release command that
+ would release all drives in an autochanger instead of having to
+ do each one in turn.
+
+ Why: It can take some time for a release to occur, and the
+ commands must be given for each drive in turn, which can quicky
+ scale if there are several drives in the library. (Having to
+ watch the console, to give each command can waste a good bit of
+ time when you start getting into the 16 drive range when the
+ tapes can take up to 3 minutes to eject each)
+
+ Notes: Due to the way some autochangers/libraries work, you
+ cannot assume that new tapes inserted will go into slots that are
+ not currently believed to be in use by bacula (the tape from that
+ slot is in a drive). This would make any changes in
+ configuration quicker/easier, as all drives need to be released
+ before any modifications to slots.
+
+Item n: Run bscan on a remote storage daemon from within bconsole.
+ Date: 07 October 2009
+ Origin: Graham Keeling <graham@equiinet.com>
+ Status: Proposing
+
+ What: The ability to be able to run bscan on a remote storage daemon from
+ within bconsole in order to populate your catalog.
+
+ Why: Currently, it seems you have to:
+ a) log in to a console on the remote machine
+ b) figure out where the storage daemon config file is
+ c) figure out the storage device from the config file
+ d) figure out the catalog IP address
+ e) figure out the catalog port
+ f) open the port on the catalog firewall
+ g) configure the catalog database to accept connections from the
+ remote host
+ h) build a 'bscan' command from (b)-(e) above and run it
+ It would be much nicer to be able to type something like this into
+ bconsole:
+ *bscan storage=<storage> device=<device> volume=<volume>
+ or something like:
+ *bscan storage=<storage> all
+ It seems to me that the scan could also do a better job than the
+ external bscan program currently does. It would possibly be able to
+ deduce some extra details, such as the catalog StorageId for the
+ volumes.
+
+ Notes: (Kern). If you need to do a bscan, you have done something wrong,
+ so this functionality should not need to be integrated into the
+ the Storage daemon. However, I am not opposed to someone implementing
+ this feature providing that all the code is in a shared object (or dll)
+ and does not add significantly to the size of the Storage daemon. In
+ addition, the code should be written in a way such that the same source
+ code is used in both the bscan program and the Storage daemon to avoid
+ adding a lot of new code that must be maintained by the project.
+
+Item n: Implement a Migration job type that will create a reverse
+ incremental (or decremental) backup from two existing full backups.
+ Date: 05 October 2009
+ Origin: Griffith College Dublin. Some sponsorship available.
+ Contact: Gavin McCullagh <gavin.mccullagh@gcd.ie>
+ Status:
+
+ What: The ability to take two full backup jobs and derive a reverse
+ incremental backup from them. The older full backup data may then
+ be discarded.
+
+ Why: Long-term backups based on keeping full backups can be expensive in
+ media. In many cases (eg a NAS), as the client accumulates files
+ over months and years, the same file will be duplicated unchanged,
+ across many media and datasets. Eg, Less than 10% (and
+ shrinking) of our monthly full mail server backup is new files,
+ the other 90% is also in the previous full backup.
+ Regularly converting the oldest full backup into a reverse
+ incremental backup allows the admin to keep access to old backup
+ jobs, but remove all of the duplicated files, freeing up media.

+ Notes: This feature was previously discussed on the bacula-devel list
+ here: http://www.mail-archive.com/bacula-devel@lists.sourceforge.net/msg04962.html

+Item n: Job migration between different SDs
+Origin: Mariusz Czulada <manieq AT wp DOT eu>
+Date: 07 May 2007
+Status: NEW
+
+What: Allow to specify in migration job devices on Storage Daemon other then
+ the one used for migrated jobs (possibly on different/distant host)
+
+Why: Sometimes we have more then one system which requires backup
+ implementation. Often, these systems are functionally unrelated and
+ placed in different locations. Having a big backup device (a tape
+ library) in each location is not cost-effective. It would be much
+ better to have one powerful enough tape library which could handle
+ backups from all systems, assuming relatively fast and reliable WAN
+ connections. In such architecture backups are done in service windows
+ on local bacula servers, then migrated to central storage off the peak
+ hours.
+
+Notes: If migration to different SD is working, migration to the same SD, as
+ now, could be done the same way (i mean 'localhost') to unify the
+ whole process
+
+Item n: Concurrent spooling and despooling withini a single job.
+Date: 17 nov 2009
+Origin: Jesper Krogh <jesper@krogh.cc>
+Status: NEW
+What: When a job has spooling enabled and the spool area size is
+ less than the total volumes size the storage daemon will:
+ 1) Spool to spool-area
+ 2) Despool to tape
+ 3) Go to 1 if more data to be backed up.
+
+ Typical disks will serve data with a speed of 100MB/s when
+ dealing with large files, network it typical capable of doing 115MB/s
+ (GbitE). Tape drives will despool with 50-90MB/s (LTO3) 70-120MB/s
+ (LTO4) depending on compression and data.
+
+ As bacula currently works it'll hold back data from the client until
+ de-spooling is done, now matter if the spool area can handle another
+ block of data. Say given a FileSet of 4TB and a spool-area of 100GB and
+ a Maximum Job Spool Size set to 50GB then above sequence could be
+ changed to allow to spool to the other 50GB while despooling the first
+ 50GB and not holding back the client while doing it. As above numbers
+ show, depending on tape-drive and disk-arrays this potentially leads to
+ a cut of the backup-time of 50% for the individual jobs.
+
+ Real-world example, backing up 112.6GB (large files) to LTO4 tapes
+ (despools with ~75MB/s, data is gzipped on the remote filesystem.
+ Maximum Job Spool Size = 8GB
+
+ Current:
+ Size: 112.6GB
+ Elapsed time (total time): 46m 15s => 2775s
+ Despooling time: 25m 41s => 1541s (55%)
+ Spooling time: 20m 34s => 1234s (45%)
+ Reported speed: 40.58MB/s
+ Spooling speed: 112.6GB/1234s => 91.25MB/s
+ Despooling speed: 112.6GB/1541s => 73.07MB/s
+
+ So disk + net can "keep up" with the LTO4 drive (in this test)
+
+ Prosed change would effectively make the backup run in the "despooling
+ time" 1541s giving a reduction to 55% of the total run time.
+
+ In the situation where the individual job cannot keep up with LTO-drive
+ spooling enables efficient multiplexing of multiple concurrent jobs onto
+ the same drive.
+
+Why: When dealing with larger volumes the general utillization of the
+ network/disk is important to maximize in order to be able to run a full
+ backup over a weekend. Current work-around is to split the FileSet in
+ smaller FileSet and Jobs but that leads to more configuration mangement
+ and is harder to review for completeness. Subsequently it makes restores
+ more complex.
+
+Item 1: Extend the verify code to make it possible to verify
+ older jobs, not only the last one that has finished
+ Date: 10 April 2009
+ Origin: Ralf Gross (Ralf-Lists <at> ralfgross.de)
+ Status: not implemented or documented
+
+ What: At the moment a VolumeToCatalog job compares only the
+ last job with the data in the catalog. It's not possible
+ to compare the data (md5sums) of an older volume with the
+ data in the catalog.
+
+ Why: If a verify job fails, one has to immediately check the
+ source of the problem, fix it and rerun the verify job.
+ This has to happen before the next backup of the
+ verified backup job starts.
+ More important: It's not possible to check jobs that are
+ kept for a long time (archiv). If a jobid could be
+ specified for a verify job, older backups/tapes could be
+ checked on a regular base.
+
+ Notes: verify documentation:
+ VolumeToCatalog: This level causes Bacula to read the file
+ attribute data written to the Volume from the last Job [...]
+
+ Verify Job = <Job-Resource-Name> If you run a verify job
+ without this directive, the last job run will be compared
+ with the catalog, which means that you must immediately
+ follow a backup by a verify command. If you specify a Verify
+ Job Bacula will find the last job with that name that ran [...]
+
+ example bconsole verify dialog:

+Item n: Separate "Storage" and "Device" in the bacula-dir.conf
+ Date: 29 April 2009
+ Origin: "James Harper" <james.harper@bendigoit.com.au>
+ Status: not implemented or documented
+
+ What: Separate "Storage" and "Device" in the bacula-dir.conf
+ The resulting config would looks something like:
+
+ Storage {
+ Name = name_of_server
+ Address = hostname/IP address
+ SDPort = 9103
+ Password = shh_its_a_secret
+ Maximum Concurrent Jobs = 7

+
+ Device {
+ Name = name_of_device
+ Storage = name_of_server
+ Device = name_of_device_on_sd
+ Media Type = media_type
+ Maximum Concurrent Jobs = 1
+ }
+
+ Maximum Concurrent Jobs would be specified with a server and a device
+ maximum, which would both be honoured by the director. Almost everything
+ that mentions a 'Storage' would need to be changed to 'Device', although
+ perhaps a 'Storage' would just be a synonym for 'Device' for backwards
+ compatibility...
+
+ Why: If you have multiple Storage definitions pointing to different
+ Devices in the same Storage daemon, the "status storage" command
+ prompts for each different device, but they all give the same
+ information.
