Apt-get install backuppc. It does the incremental backups others have
suggested. It can use rsync, samba, nfs, ssh & tar for backups on
Linux, Windows and Mac OS X clients. It also implements pooling, so
that if you have an identical file on 5 computers, it only keeps one
copy of it instead of 5.
The web interface makes it very easy to retrieve a single file from any
of the backups and you can configure how many backups it keeps around.
I currently have mine keeping 6 days of incrementals, 2 weekly full
backups and 2 monthly full backups. This gives me the ability to pull
files from recent backups, as well as have a little insurance going
back 2 months.
I would expect your disk usage to be around half of the 1.4TB estimate
you mention above, if you use BackupPC. It also has other extras, such
as the ability to give users logins to the web interface. Based on
their username, it will then restrict their access so that they can
only retrieve files from their own computers and can't see which other
computers/files have been backed up by the backup server.
HTH,
