Listening to Leo LaPorte's show last weekend, he offered this advice on backing up:
3-2-1
Make at least 3 copies; They should be on at least 2 different types of media; there should be 1 different geographic location.
'Nuff said!

There are different versions (3 backups or 1 primary and 2 backups). Most important. Common ground: 2 different storage media and 1 copy offsite. I have always kept multiple copies of data I want to keep (after several floppy disk fiascos years ago)

The 3-2-1 Rule
The simplest way to remember how to back up your images safely is to use the 3-2-1 rule.
We recommend keeping 3 copies of any important file (a primary and two backups)
We recommend having the files on 2 different media types (such as hard drive and optical media), to protect against different types of hazards.*
1 copy should be stored offsite (or at least offline).
