Oh, I don't have any 'other' product that works so magically.  I am learning bacula on home/family gear.  So in my particular case I'm trying to do a full on 150GB wirelessly to an old box running CentOS with zfs-fuse on 4 drives.  Everything about this is slow, but zfs has given new life to 4 drives that were otherwise trash.

I borked up the bacula-sd.conf once and the backup crashed midway.  Smaller chunk backups might help...

Out of curiosity, what backup product are you currently using that _does_ cleanly handle loss of communication between the client and the backup server, resuming the next backup at exactly there the previous one failed?  I don't know how many remote sites you're going to be backing up, but if it were me and just a few sites, I'd probably deploy a bacula host in each site (you don't need a lot of expensive server horsepower to deploy a perfectly functional and reliable bacula server).  If your links are unstable enough that it's a problem for backups, then imagine when you need to do restores and you're having those same circuit stability issues while everyone is frantically asking you, "How much longer?!?!".  People don't much care if a backup takes 8 hours overnight, but they care *immensely* when everything has ground to a halt during a business day and you're explaining that the restore will take that same 8+ hours, and may have to start over completely because your links are bad.  At restore time, I'd much rather be restoring at near wire speed from a local system.

Regards,
Mark
