Hi all,

My question is, if it is generally possible for the file-daemon to
recover from a lost network connection during a backup job.
Yes, but this takes a while. Default timeout is two hours. There are
reasons for that long timeout period, but don't ask _me_ ;-)
What happened here:
I started a full backup of a Windows XP computer (file daemon) to a
linux computer (running the director and storage daemon). After several
hours the network connection was lost (lets say physically). The file
daemon on windows aborts the job (with status "error"), while the
director and the storage daemon still saying, that "the job is running".
Questions:
1) is this normal behaviour, that a connection loss of the file daemon
results in the abort of the backup job?
Yes. Everything else would only make things much more difficult and you
wouldn't gain a lot.
2) is it possible to resume such a job?
No. But you can have failed jobs rerun.
3) the backup was done to tapes. Is it possible to reclaim the space
used by the now aborted job, without loosing data on the tape from
previous jobs?
In theory this is possible in one certain case. Bacula itself doesn't
support this, though.
The one case is hat you only have one job writing to a tape
simultaneously, and no other jobs running afterwards. Then, you could
set the file number in the catalog to the value before the job started,
wind the tape to that place, and write an EOF/EOD marker.
I wouldn't try that.
If the job already used up more than one tape, you can simply delete the
job from the catalog and prune the volumes - the used volume should be
purged afterwards.
All this is possible when you have multiple jobs writing to tape
simultaneously, i.e. when running jobs in parallel and not spooling.
These questions may sound silly, and may be answered in the
documentation, but I haven't found anything.
They're, to my knowledge, not answerded explicitly.
