Backup software

[Mark Woodward]

While I've got some free time on my hands, I decided to start work on a 
project. At its core, it is very much like a standard backup system. 
What makes it different from a regular backup is what you do with the 
data retrieved after the backup. I know it is a long shot or even a 
fools errand to start anything so pedantic and well traveled, but there 
is a specific need that I believe has been identified, but requires 
"backup" done in a specific manner.  Anyway, who knows? I'm already 
testing and using some of the core pieces and I have to say, I like it.

My target OS are Windows, MacOS, and Linux. It will run on desktops, 
servers, and even some of these little NAS boxes that run Linux.

My question for you guys is what do you *want* in a backup. We've all 
used these feature laden things that are out there, 99% of which is 
pointless.  What are "must haves?" What is something you've wanted but 
can't find? What are features that are most pointless and why?
