btrfs-restore — try to restore files from a damaged btrfs filesystem image


btrfs restore [options] <device> <path> | -l <device>


btrfs restore is used to try to salvage files from a damaged filesystem and restore them into <path> or just list the tree roots.

Since current btrfs-check(8) or btrfs-rescue(8) only has very limited usage, btrfs restore is normally a better choice.


It is recommended to read the following btrfs wiki page if your data is not salvaged with default option: https://btrfs.wiki.kernel.org/index.php…
