Currently I use rsync to backup our colocated server to an in house file server, but I'm wanting to backup a few exchange 2003 boxes as well. Some are in house, some are remote. What windows based software is there for remote backup? I have veritas backup exec and such, but I haven't played with them yet. Any suggestions? Full backups are NOT going to cut it.. only changed data. (Incremental backups i think they're called?) Bandwidth is of a concern.. once a month full backups are feasible.. but 200GB every night... hell no.
