general, it should be very fast.
New Features in 1.40.0 (beginning of release info)
+- Additional support for removable devices. See the
+ Requires Mount, Mount Point, Mount Command, and Unmount
+ Commands in the Storage daemon configuration chapter:
+ http://www.bacula.org/dev-manual/Storage_Daemon_Configuratio.html
+ Also see the Edit Codes for Mount and Unmount Directives in the
+ same chapter.
- There is a new cross-compiled Win32 File daemon that now has all the features
that were previously only in the Unix versions.

+Subject: [Bacula-devel] DVD + packet writing + UDF
+
+Hello,
+
+is anyone using this approach in production?
+
+I do for about a week now. And it appears to be easier to setup and is,
+in fact, quite media independent. (I actually gave up on trying the
+growisofs/dvd-handler method - bacula constantly rejected most of my
+media...)
+
+Here is how it works for me (all done with bacula 1.38.5 on FC4 with the
+udftools package installed):
+
+1. load udf file system support (modprobe udf)
+
+2. create a packet writing device on top of the dvd drive (pktsetup
+ dvd-writer /dev/hdc)
+
+3. format a blank media with UDF file system (mkudffs --media-type=dvd
+ /dev/pktcdvd/dvd-writer), I tried with DVD-RAM, DVD+RW and CD-RW
+ media. All appear to work fine - at different speeds of course.
+
+4. mount the freshly formatted media (mount -t udf
+ /dev/pktcdvd/dvd-writer /mnt/dvd-writer -o noatime). Note that
+ 'noatime' makes the media living longer.
+
+5. configure the SD as it would write to hard disk:
+
+ Device {
+ Name = DVD-Writer
+ Media Type = DVD
+
+ ArchiveDevice = /mnt/dvd-writer
+
+ LabelMedia = no # I want only one Volume per DVD
+ AutomaticMount = yes
+ RemovableMedia = yes
+ AlwaysOpen = no
+ }
+
+Now the whole thing can be automated further: steps 1, 2 and 5 are
+one-time system setup.
+
+Step 3 would require some logic to determine whether a media really is
+blank. I guess something the like is already in dvd-handler?.
+
+Step 4 should be automatic with 1.39.5+ (with the RequiresMount,
+MountPoint, MountCommand... etc... options being more general). I havn't
+tried this yet.
+
+I do not know how stable this is yet. I am a bit concerned because I
+read in a older mail (from Nicolas Boichat, end of 2004) that he
+considered packet-writing/UDF as not reliable enough at that time.
+
+However, the few restores I tried were all successful. Also I can read
+the DVDs on at least one other computer. Maybe the UDF and pkcdvd code
+matured in the meantime? I'll leave it running here and keep on testing...
+
+best regards,
+Stephan

+ The problem is that it requires m4, which is not present on all machines
+ at ./configure time.

Kern notes: I think this would add very little functionality, but a *lot* of
additional overhead to Bacula.

+Item 1: include JobID in spool file name
+ Origin: Mark Bergman <mark.bergman@uphs.upenn.edu>
+ Date: Tue Aug 22 17:13:39 EDT 2006
+ Status:
+
+ What: Change the name of the spool file to include the JobID
+
+ Why: JobIDs are the common key used to refer to jobs, yet the
+ spoolfile name doesn't include that information. The date/time
+ stamp is useful (and should be retained).
+
+
+
+Item 2: include timestamp of job launch in "stat clients" output
+ Origin: Mark Bergman <mark.bergman@uphs.upenn.edu>
+ Date: Tue Aug 22 17:13:39 EDT 2006
+ Status:
+
+ What: The "stat clients" command doesn't include any detail on when
+ the active backup jobs were launched.
+
+ Why: Including the timestamp would make it much easier to decide whether
+ a job is running properly.
+
+ Notes: It may be helpful to have the output from "stat clients" formatted
+ more like that from "stat dir" (and other commands), in a column
+ format. The per-client information that's currently shown (level,
+ client name, JobId, Volume, pool, device, Files, etc.) is good, but
+ somewhat hard to parse (both programmatically and visually),
+ particularly when there are many active clients.
+
+Item 1: Filesystemwatch triggered backup.
+ Date: 31 August 2006
+ Origin: Jesper Krogh <jesper@krogh.cc>
+ Status: Unimplemented, depends probably on "client initiated backups"
+
+ What: With inotify and similar filesystem triggeret notification
+ systems is it possible to have the file-daemon to monitor
+ filesystem changes and initiate backup.
+
+ Why: There are 2 situations where this is nice to have.
+ 1) It is possible to get a much finer-grained backup than
+ the fixed schedules used now.. A file created and deleted
+ a few hours later, can automatically be caught.
+
+ 2) The introduced load on the system will probably be
+ distributed more even on the system.
+
+ Notes: This can be combined with configration that specifies
+ something like: "at most every 15 minutes or when changes
+ consumed XX MB".
