Hi all, I know the easiest answer to this question is "don't do it in the first place, and if you do, you should have a backup", however I'll ask it regardless.
Is there a way to backup the ZFS metadata on each member device of a pool to another device (possibly non-ZFS)? I have recently read a discusson on this list regarding storing the working metadata on off-data devices (mirrored I assume). Is there a way today to walk, and save, the metadata of an entire pool and save it somewhere? The main motivation for the question is that I recently ruined a large raidz pool buy overwriting the start and end of two member disks (and possibly some data). I assume that if I could have restored the lost metadata I could have recovered most of the real data.
