Hi folks,
I was wondering if anyone could advise on this...
Basically I'm in the process of putting together a server for work. At the moment they backup their existing server to a 160GB USB drive but I'm looking to put some bigger discs in this new server. Now to hopefully make backups easier (for the users) I was hoping to setup two drives internally in the server in a mirrored array but I wondered if it was also possible to use a third drive in a mirror too (so basically one drive mirrors to two other drives).
The idea I had was if this is possible, I could attach one of the drives externally via eSATA so it can be taken off site and in the event of a server failure this off site backup could be plugged in and the server could be back up and running in minutes rather than a good few hours of re-installation (I was thinking of having two external drives so they can be alternatively swapped every day).
