I'm running testdisk now to search for all the partitions

I honestly forget where I put the backup then I zapped it. It's on a

ZFS filesystem on another drive too just I have no idea how to get at it

That fs is also overwritten, the backup is my best chance but wiped the partition table, made new partitions, and then wiped that partition table... I can't remember what the layout was but I think testdisk can search all of them to find files on them

Because very little else happened in between it should just be a matter of catching the right ext4 FS header and searching for it's consist and...

This is scary, and I feel so sick right now

I've recovered stuff using testdisk before and it was tense but not this tense

I am not doomed but this will be harsh if I can't get the keys

I will go defcon1 on this new

I know the wallet is on these two disks and highly unlikely it was overwritten because the previous FS was quite full thanks to Bitcoin, I think it was 2.5tb out of 4 so the file is very likely way past the middle of the disk and maybe 20gb was overwritten, likely at the start of the disk

The findbtc tool just doesn't do anything except report the location I have to use other things to pull them out then try to decrypt them using a Bitcoin core installation

So yeah this is nervewracking

And yeah, I can go to that length. I have drives that can take both, I fortunately got 2 4tb disks... One is a windows install but after backing up the data on it to my spare smaller disks and ensuring I have all my keys for all else done I can duplicate the primary zfs containing disk too

I'm sure I am going to figure this out.

It reminds me I was going to run vanilla, which is a layered snapshot driven Linux. It would have been easy to run it on the machine that had Bitcoin core, and this problem would have been much easier to recover from... It was literally because I stupidly used zfs on it

Never ever zfs. It is the Wayland of storage, fucking shit.
