Fix backup script removing image after unsuccessful pivot
...
If pivoting the VM backing storage back to the original image fails
(e.g. VM being down at that time), the script currently still deletes
the hotswap image, which means that all changes since the creation of
the hotswap image are lost.

Some software, e.g. go-ipfs, is rather aggressive in scanning local
