how much data?
is your raid rebuilding? raid1? raid5?
how is connected the remote machine? 100 MBit? 1Gbit?
you don't need server-manager to monitor restoring..
just login as root and use top, iptraf, df (open at least 3 different sessions)
you'll see what's running (dar), network traffic speed (iptraf), disk space occupation (df)
in the meanwhile, I suggest you to smoke a lot of cigarettes and drink coffee
if you are not a smoker, just start
