I added a network interface to the backup server on the same segment
as the client and the timeout disappeared, so it seems my firewall was
expiring a TCP session somewhere along the line. Unsure whether it's a
configuration problem on the Bacula or firewall side -- I expected the
heartbeat to prevent this.
Anyhow, I'm not sure Bacula is the right solution for this type of
backup: the attribute despool has been running for nearly three days
straight now. Does anybody else have experience backing up tons of
files? Any recommendations on making it not suck?
