Volume sizing is used for disk-based volumes – do not use it for tape media
volumes.
If you are using spooling (recommended) your spool size parameters are used to
control the size of your job spool and the total spool space available. The
example below shows 50GB of job spool size and a total of 1TB of spool space.
You will need to try sizes that are appropriate for your environment and see
what performs best for you. The job spool size when reached will write to tape
at that point. It will continue with spooling and writing to tape media until
the end of data has been reached. Also for something like a NAS, it’s best to
break the backups into more manageable chunks. Don’t try to backup the entire
NAS in one job. And yes, use the heartbeatinterval feature.
Maximum Spool Size = 1000GB;
Maximum Job Spool Size = 50GB;
You don’t mention which version of Bacula that you are using. If it is 7.4.x
is has a resume command that will restart failed jobs roughly from the point
that the backup failed. The documentation will talk about this under
Incomplete Jobs. I have found the use of this feature to be great when it
works, otherwise it will start from the beginning as a new job using the job
schedule to determine the level of the backup. Client connection drops are hit
and miss on the resume working.

Yes, most likely. In the 3 hours or so it took to despool to tape, the
SD->FD TCP connection was dropped for some reason. I am of the opinion
that not all interfaces interpret IEE 802.3az Energy-Efficient Ethernet
in the same way, and when one interface puts its transmitter into sleep
mode, the receiving interface sees it as a dropped connection. Setting a
heartbeat should work, if that is what is happening.
Okay thanks, will add that. I guess I will have to start the backup over, how
do I remove what's in the catalog so that I can reset the tape?
Is there a way to write to tape every 50GB or so? I see setting for volume
size but as I understand it (newbie and all) that that refers to the tape size
not the "chunk" size.
Thanks, Ian
