The server components of SQL Backup have now been compiled to run on 64-bit versions of SQL Server.
The beta (which is feature complete) is public and can be downloaded from the Red Gate forums: http://www.red-gate.com/MessageBoard/viewforum.php?f=45.
It’s also worth looking at if you have 32-bit servers too by the way, it’s the same download and install procedure!
It comes with a 14 day trial and a full install, so you can upgrade from previous versions of SQL Backup.
I’d appreciate any feedback posted on the forum, for which is rewarded with a stylish SQL Backup T-shirt!
