Archive a Backup? Image to DVD?

[kcmidwest]

Hello, I've used SD a few times, I really like it's reliability and simplicity. Plan to upgrade soon to use the advanced features.

My question: Could I create an archival copy on DVD (to store off-site) with the following method?

A) Use SD to backup my entire boot drive to a disk image.

B) Burn that image to DVD(s) *

* I realize that image will be larger than a DVD. Does a Disk Image 'look' like one big file to OSX? Could I use a program like 'MacHacha' to split that file into 1.9 GB segments to burn (2 segments per) to DVD.

Note: MacHacha appears to be just a front end to the standard terminal split and cat (join) commands, so I feel pretty safe with this method - not really a 'proprietary' method.

If no one knows this from experience, I hope to try it later this week, I'll report back success/failure.

Thanks!
