For redundancy, it's hard to beat triple mirrored drives on a SAN, with RFS on a 4th i/o channel. You break the mirror between drives 2 & 3, and then drive 1 & 2 remain mirrored. Back up off #3. When finished, reestablish the mirror between 2&3. RFS can be then write to 2 drives with a 0,1 configuration sequentially - which is fast. However, RFS can take 25% to 50% of resources, so have a fast box!!!

Doubletake is an O/S answer -- but you cannot use the 'DoubleTake' data to
host a reporting server, can you? UniData Replication is great for being
able to have the database in two places at once with for either backup, hot
spare, or 'query only' access.

We are using Double-Take to replicate.
