Page 3 of 4 I want to keep multiple copies of my backup folder, say every 10 minutes for 48 hours, so I can dip back into previous versions in case I want to recover something I deleted.

The problem is I wanted timestamped folders, but I couldn't figure out how to renumber the folders while retaining the timestamp in the name.
