Important files on my Macs are backed up to each, backed up to Time Machine, and backed up to extra external hard disk drives. Online backups have become trendy. Scott Rose looks a five of the best (along with a few recommendations that match my own backup process):
I compared the 5 leading online backup services, and my #1 favorite online backup service is now backblaze.com, because it is totally Mac-like in its simplicity and ease-of-use. You install Backblaze once, it auto-configures itself for backing up your Mac, and you never have to worry about it again. Backblaze just hums along quietly in the background, always keeping your Mac backed up in the cloud.
The problem I have with online backup services is the amount of time it takes for the first backup. Over 200 gigabytes for iTunes, iMovie, and iPhoto files takes freakin’ forever.
