that capcity is ez ...
get two or three 300GB disks ..
if budget was tight .. put those backup disks into 3 different PCs
- on the 1st, 4th, 7th, 10th, you backup to backup-server1
- on the 2nd, 5th, 8th, 11th, you backyp to backup-server2
- on the 3rd, 6th, 9th, 12th, you backup to backup-server3
- all done in cron
- you never overwrite yesterdays backup .. or last week or last months
backup ... ( depends on how accurately you can detect an intruder
or an expired/obsolete file somebody might want from long ago )
- backups is trivial and accurate when you push data to the backup boxes
tons of free backup scripts:
