Data recovery from zfs pool?

Question

ZFS

Hello!
I had deleted the data in the /home directory, how to restore it.
assembled by the system during installation, rpool raid0 as part of two disks sda and sdb. The utilities that are offered for data recovery indicate the disk from the dev partition.

Answer 1

Check if there are snapshots in the system:
zfs list -t snapshot
If there is a snapshot of the required dataset, the file can be restored.
If not, you can't.
ZFS is Copy on Write FS. The principle of operation is different from the usual EXT4.
R.Lab has R.Saver software, the functionality of which states that it can recover deleted files and has support for ZFS. But clearly these two concepts are not connected. It is necessary to test - https://rlab.ru/tools/rsaver.html

Answer 2

If you can’t restore from a backup, then I advise you to contact data recovery offices.
