Using robocopy to fashion incremental or differential backups?

[LeperousDust]

This should be possible with all the switches available, but i can't quite get my head around it. I know i'd need a few scripts set up to acheive this right? One as the main backup, and then others as incrementals just copying changes, but then i realise i probably wouldn't be able write them to different folder names?
Hmmm quite confusing...

Hmmmm i'd rather not be setting them as archived and non archived all the time as i use some of the files (in documents folder) a fair bit...

At present i've got what is essentially a mirror, and i was just thinking of how i can make this a little more idiot proof in case i do something silly and back it up But i'd rather not have multiple mirrors, since i'm backing up over 50Gb of data at a time...

if you run robocopy on say 10gb of data, it'll copy the 10gb, then if you added say 20mb to the folder, and edited a few of the original files

it'd only copy the 20mb and the updated files

It wouldnt do that if i wasn't copying to the same folder though would it, if you get me? Since i'd not want to overwrite at the destination the data that had been changed/added.

The archive attribute is a possiblity, i'll have a see what i can rustle up, i guess its the simplest solution
