zfs-autoverify tool

[psy0rz]

Tool to verify the actual backups by mounting the common snapshots and running rsync in verify-mode or sha256sum on the blockdevice.

This has become more urgent since a bunch of encryption bugs in ZFS have been discovered in some edge cases.

And you should offcourse always verify your backups. (although i blindly trusted zfs thus far)

the plan was to finish 3.1.x features first before new big changes, but this is more important. (and shouldnt be that difficult after some refactoring)

[psy0rz]

the alpha2 version in git is working, needs some debugging and tuning. (e.g. cleanups on ctrl-c are still messy and can leave stuff mounted/cloned)

If created a tool to generate the actual checksums: https://github.com/psy0rz/zfs_autobackup/wiki/zfs-check

zfs-autoverify will then use this tool to compare checksums. In the main time you can use zfs-check manually to check some datasets.
