Yosemite backup by Barracuda. »www.barracudaware.com/products/s ··· r-backup
They have an upgrade offer where you can send them your BackupExec key and they'll give you a discount. Their licensing is a lot easier to handle, depending on what you're going for. Especially since their Unlimited license is $1500 pre-discount. I have it working with SQL, Exchange, and different flavors of Dell LTO-2 drives.
