signal ALRM is always caused by BackupPC aborting the backup after
$Conf{ClientTimeout} has passed without BackupPC detecting any progress. In
the case of rsync(d), this needs to account for the complete backup due to the
way it is implemented (for tar type backups, I believe it is only the duration
of the longest file transfer). The default value is 72000 seconds == 20 hours.

Raise $Conf{ClientTimeout} to a value that will allow your backup to complete.
A too high value has the drawback of not detecting stuck backups for that
amount of time. This is nothing to worry about for your first backup. Perhaps
just add a '0' and change the value back after the first backup has
successfully completed. Future rsync(d) backups should hopefully complete
significantly faster.

I'm not sure why you repeatedly get a partial dump 0 though instead of the
transfer restarting from the point it was originally interrupted (using the
previous partial as reference). That would allow the backup to eventually
complete even without increasing ClientTimeout, but it does not seem to be
happening in your case.
