Today suddenly when performing a rootfs + opts, it backed up to SD a normal rootfs image, and then proceeded with the optfs, but it never stopped, and i couldnt cancel either, until error code 2 popped up (max file size 4gb?)

Booted pc in gparted and checked optfs, mydocs and sd card.
Removed and purged backupmenu.
Reinstalled. Same problem.

When backing up optfs, it is unstoppable.

Any ideas?
