    I have just erased my MBA's SSD and re-installed a fresh copy of Mountain Lion, set up all programs from scratch etc.

    If i enable time machine on the same external disk will it overwrite my previous backups?

    I would like the option to go back to my pre-erased config if i need to, is this possible?

    Thanks
