[BackupPC-users] Backups aborting after 2 hours

[<bpc...@xo...>]

I've installed BackupPC and am happily using it to backup various clients
via smb, tar, and rsync.

However I have one client with a lot of data to backup over a slow 10Mb
link. Backups of this host consistently fail after 2 hours. Here's a log
sample:


2003/11/10 15:22:59 full backup started for directory /
2003/11/10 17:23:09 cleaning up after signal ALRM
2003/11/10 20:00:01 incr backup started back to 2003-11-06 05:38:14 for
directory /
2003/11/10 22:00:06 cleaning up after signal ALRM
2003/11/10 23:00:01 incr backup started back to 2003-11-06 05:38:14 for
directory /
2003/11/11 01:00:06 cleaning up after signal ALRM
2003/11/11 02:00:01 incr backup started back to 2003-11-06 05:38:14 for
directory /
2003/11/11 04:00:02 cleaning up after signal ALRM
2003/11/11 05:00:02 incr backup started back to 2003-11-06 05:38:14 for
directory /
2003/11/11 07:00:12 cleaning up after signal ALRM


I get the same results whether I use tar or rsync for copying files.
Where is the Alarm signal coming from? I don't see it in a quick grep
through the code.
Is this a limit intentionally built in to BackupPC?  Where can I change it?

Thanks,
