Yes, I understand how I could use dump/restore. But forget about all
this. Forget about my reasons for wanting it.
All I want to know is whether or not there exists a tool that will
let me rollback a snapshot without mounting it, dumping it, or
anything like that. Just by flipping some bits in the superblock, or
some other small changes to an (unmounted) file system. Something
really easy. No extra disk, no excessive copying, no nothing. Just a
simple
# umount
# snap_rollback
*wait 10 seconds*
# mount
.. and I'm set.
I believe it should be possible. And if nothing like that exists, it
should be made. I could look into it, but I would have to learn a
lot more about the inner workings of the file system first.
not that i know of, and IMHO for good reason. i would not trust
anything of that nature with data that i deemed important enough to
snap shot in the first place.
