I have Arcserve 2000 and I need to know what should I be backing up on Windows 2000 and 2003 servers. I pretty much know that I need to back up system state, data and such, but I am looking for the best way to backup my servers and plan it out correctly so that if I need to restore it can be done successfully. I also have SQL servers and a Exchange server. I have heard about brick level backups on Exchange. Is this the best way to backup an Exchange server? Thanks.
