I work for a small engineering firm so our data needs aren't that insane.
We have about 500GB of active data that we backup.  The rest are closed jobs
that have been archived which I'll touch on how we handle that as well.

We have two levels of backups both are using rsnapshot.  The first level is
our onsite backups where we do a snapshot every other hour during normal
business hours to a second onsite server.  We keep 30 days of these
snapshots.  This is primarily for the times where someone accidentally
deletes or over writes a file.  But this server is also setup with some
scripts to reconfigure itself to step in for our main file server should
there be a major hardware issue where the redundancy can't deal with.

The second level of backups is our nightly offsite snapshot, also using
rsnapshot.  This is done via a VPN tunnel to one of the owner's house where
he has a server set up in his basement.  We keep 365 nightly snapshots on
this server.  This server is also setup with scripts to replace our main
server as part of our disaster recovery plan in the case of fire or other
act of God which takes down our primary site.

Then we have long term archival which is not included in the snapshots.
This is handled by a Perl script that we wrote which scans our job folders
once a week for any jobs that are marked as closed in our ERP and the files
haven't been modified in 90 days.  When these two conditions are met the
project is compressed and moved to an archive volume on the onsite backup
server which is then replicated to the offsite server using rsync.
