Yes that is exactly what we have been doing for years. Our work mail server occasionally fails as we tend to use old workstations as servers. Each time it has taken just minutes to get Mercury running again by merely copying the last automated backup and starting the program. There are loads of backup programs you can use, we use Arcserve and make automated copy's to disk on a backup server every night. You can of course just take the backup copy pop it in a new server share and map the appropriate drive, start the Mercury.exe and away you go running again in moments.
