I use rsync and spare inexpensive computers to backup our servers.

Our business requires 7x24 computer access with minimal downtime when 
the server fails.

I have 3 backup computers.

1st - next to the main computer.

2nd- at the other end of the building.

3-rd at my house. 

 hourly all our data files are rsynced to the 3 backup servers. This 
takes  1-3 min.

 also 2x  per hour  our main data files are synced.  this takes < 2 min.

 Rsync is a great program for backup as it sends just the parts of the 
file which changed.

 In addition we use dds-4 tape to backup 1x per day. the tape is taken 
offsite.

So use rsync over ethernet to backup to a spare computer or 2.
