[Bacula-users] Inconsistent backup success rate

[Andreas F. <and...@un...>]

Hello,

Currently we are attempting to backup 47 servers per night with very
inconsistent results.

It would seem that more than half of the backups (full and incrementals) are
failing due to a network timeout error (Network error on data channel.
ERR=Operation timed out).

All of the servers are on the same network, the operating systems are varied
as well as the versions. One night the server will backup successfully and
the next it will fail. There are no firewall rules preventing these
connections and almost all of the hardware is new.

As it is, we are allowing a maximum of 8 concurrrent backups to run at a
time. We have also scheduled the backups so that they are spread out
throughout the evening and not in one big group.

Can anyone please let me know if eight is an unreasonable number of backups
to run at a time? What are other people doing for this number of servers?

I am running out of ideas and may have to start investigating other backup
options should I not be able to resolve this. I like bacula and the way it
works so I would rather not move away from it if it can be helped.

We are running the backups using bacula 1.38.2 on a FreeBSD 5.4 server.


Thanks .. any assistance or advice is appreciated.
-Andreas
