I found there is a tool called r-studio, and the demo version let's you recover files up to 256kb... Iirc, the wallet files I already did find, dated at march, were like 28kb, so this is very hopeful I can even run the scan on the backup drive while the 4tb volume is being duplicated It says it also supports BSD filesystems but I see no mention of zfs, however... Another strike against it... This backup volume has barely been written to since the partition table was reset so there is very good chance it finds the files on an ext4 volume It has already reported finding 123434 files on ext2 which sounds about right for a Bitcoin data directory Just to be able to find the newest wallet.dat, it probably will find the very one from yesterday and all keys will be in it... I will back them up to a DVD and then find a tool that dumps the private keys and public keys, check the utxos and hopefully have good news to not lose one sat Just a Sunday and a bitch slap from God I have had coming 😂
