Hello and welcome to the forums.
I have used esXpress for backup and recovery of SQL and Domino boxes with great success. It just works like it is supposed to, and you don't really have to think/worry about it.
Another thing to think about is your retention policies and whether you need backup data on tape/offsite/etc.
Good Luck!
