I finally got a backup to work that is close to ideal for me. It cumulatively saves backups of a file to a sub-directory "\backup", creating the sub-directories if necessary.
Go to the Advanced pull-down. Click Configuration, Navigate: to File Handling, Backup.
Under Backup Files on Save: check the No Backup button (no .BAK).
Leave the Default backup directory: empty.
Under Version Backup: check the On save box, and enter "\backup\$n$e $y $m $d $H $M" in the Format: box. This works in 14.00b.
My ideal backup would be "\backup\$n$e $y$m$d $3c", but that doesn't work yet.
