Quick/easy question...hopefully(!) I have set it up to where it is automatically running a diff backup twice a week, but what I didn't expect was ea diff b/u is a new file. I expected it to just create/overwrite one diff file; ie. you have the original b/u file and just one other diff b/u file that is modified or rewritten ea time. Anyways, can I not just delete any older (than the most recent) diff b/u files and just keep the most recent? Otherwise, I'm bound to eventually use up all the space. BTW, Chustman, I have another literary pet peeve I could add to your tag line - the plural possessive is 'their' not 'there'
