here is my backup syntax. As you can see I'm pointing to two different servers. By the way, this is a active/passive clustered environment. I'm tryiing to set this up so that whatever node is active this syntax will work.

Thanks for your help!

BACKUP DATABASE AdventureWorks TO DISK = '\\vrdbserver1\sql server backups\SCVR2000\adventureworks.bak'

MIRROR

TO DISK = '\\vrdbserver2\sql server backups\SCVR2000\adventureworks.bak'

WITH FORMAT,retaindays=14
