I would like to start using fbackup to backup my files (around 260GB) every week. I have two internal HDs (500GB each) and I want to mirror backup from on HD to another. My question is that if I do this, I assume the first backup will work fine...but happens to the second time it runs? Will fbackup overwrite the first set of files, not backup the files, or attempt to and then fail when the HD gets full?
Thank you for your time.
