I run rsync every hour on multi-terrabyte systems with no problems. The
NASes do have a private GB network to push the data through, so the user
network doesn't see the network traffic generated by rsync. I can have
anywhere from just a couple hundred megs, to 100 gigs of data change inside
of an hour.

I'll have to read this. I wrote my configuration up on how to use rsync for
hourly, daily and weekly backups here: http://marks-tech-pages.blogspot.com

Rsync really shines, I've totally abandoned backing up to tape. It's nice to
have restores run at network speeds.

Thanks!
