I have not been able to restore my catalog dump from a previous backup
on a different system. I'll start with the problem I can't solve, and
then note a couple I did solve for the archvive (and comments).
I'd be very grateful for any help; I'm kind of dead in the water til I
get my files back. The original system died, including its primary
disk.
I think the key problem is that bscan is not setting media, although
invoked with -m:
<terminal>
$ bscan -s -m -b

Records added or updated in the catalog:
0 Media
0 Pool
1 Job
1 File
</terminal>
The job does appear in the catalog after this, and so it can't just be
that I lack write access.
The bsr file has MediaType but no Media entry:
<bsr>
# 18-Apr-2013 00:08:23 - BackupCatalog.2013-04-17_23.42.00.07 - Full

VolSessionTime=1366266984
VolFile=0-0
VolBlock=252654358-314892037
FileIndex=1-1
</bsr>
bacula-sd.conf includes
<conf>
# compatibility with old setup
Device {

}
</conf>
When I run the restore job, I get an error about the media record

Context:
1. The backup server and client are the same machine.
2. bacula 5.2.6 on 64bit Debian Wheezy (amd64).
3. backup created by bacula 2.4 on 32 bit Debian Lenny (i386).
4. backup was encrypted. I have copied the keys.
5. The new system and the old system have different names.
6. Backup is to disk.
Finally, here are some discoveries along the way:
1. The final argument to bscan, described as a device in the
documentation, needs to be the name of the storage section in the
config file.
2. If one provides a directory rather than a file for the bsr option
when running the restore, the director consumes an entire CPU while
the other server processes are idle. As far as I could tell this went
on forever, and it was not interruptible by cancel from the console.
This seems like a bug.
3. Restoring from the bsr does not work unless appropriate catalog
entries are present. The manual, e.g., 37.8 "Restoring a Server"
seemed to imply this was not necessary, though it does mention using
bscan shortly after using the bootstrap file.
