Les, that's a pretty good idea, running two, but I cannot do that with these 
systems sadly. It'd be really nice to not have to take the machine down to do 
the backup though. So I guess that's my question, I'm looking for a way to 
backup the pool over Ethernet while it's running. Double twice the backups 
would be great but having it done once at all is tough. The machine doing it is 
barely able to because of the amount of rsync operations and hardlinks. My 
other machines are even lower power so they'd be far less effective.

While it's possible to dd an lvm snapshot, that's 1TB/day which is quite a huge 
amount of time and bandwidth consumed. Is there no other solution like ddsnap? 
I mean, since my BackupPC pool is on an lvm, doing a dd itself isn't the 
problem. It's that it's 1TB/day or more depending on my file system size. It'd 
be really nice to have a solution to sync only the changes of that day which 
then, I can snapshot on the other machine. In my case, that other machine is 
the iSCSI target. I think DRBD is my best bet now, but it's more than a handle 
to figure out; that's for sure.

Has anyone tried DRBD before?
