How to access and delete BackIntime backups (failed backups, from failed installs)

When trying to restore /home and /etc to a newly installed drive, I created (by mistake) a BackInTime directory inside the main BackInTime directory (of the drive I was restoring from). I only realised what had happened after I had backed up the fresh installed Trisquel and couldn't find where I expected it to be.

It was a mistake and a half, I have no idea how I managed to be that creative :)... The backup (in the sub-folder) is quite big and just redundant clutter now, as that Trisquel install failed!!!

Not a happy bunny at all. Please enlighten me!

With huge pre-thanks!
