Set up normal backups to tape, probably already done. Set up the file:driver to use the Snap server Set up the RAIT driver to mirror the backups to two devices, one the file:driver the other the LTO. Use the LTO for longterm storage, the Snap server for immediate availability of backups for recovery. -- Jon H.
