2 main options...... a regular ghosting as suggested by Alex, or for
online redundancy, a RAID solution.... RAID 1 is mirroring, which means
as soon as you change something on your main disk, your second disk gets
the same thing written to it, which is great for failover redundancy,
but no use for viruses, accidental deletion etc, so you still need to do
backups....

It's trading off how much your data changes, what volume of it changes
etc to decide between a full disk to disk copy once a week, or a second
by second disk copy.

If you want raid, you can either get an add on PCI card to do it, or get
a motherboard that has it onboard, or worst case do it in software, but
that's just wasting processor cycles!
