Everything on our network backs-up to the server and each computer also backs up to a 20gig travan. The Seagate tape drives were in place before I started working before adding the backup server as they only had one tape per computer and had bad backups overwrited on the tapes. Now accounting has 10 tapes which backup nightly and therefore they have 10 days of backups without overwriting as they deal with government agencies and can not afford to lose the data. Also all clients back up weekly to the server and each system has 2 backups so they only overwrite backups 2 weeks old and there will still be recent back in case.
