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.

Note: It is recommended to read the following btrfs wiki page if your data is not salvaged with default option:


get snapshots, btrfs restore skips snapshots in default.
get extended attributes.
restore owner, mode and times.
restore symbolic links as well as normal files.
ignore errors.
overwrite directories/files in <path>.
-t <bytenr>
use <bytenr> to read root tree.
-f <bytenr>
only restore files that are under specified root whose root bytenr is <bytenr>.
-u|--super <mirror>
use given superblock mirror identified by <mirror>, it can be 0,1,2.
-r|--root <rootid>
only restore files that are under specified root whose objectid is <rootid>.
find dir.
list tree roots.
dry run (only list files that would be recovered).
--path-regex <regex>
restore only filenames matching regex, you have to use following syntax (possibly quoted):^/(|home(|/username(|/Desktop(|/.*))))$
ignore case (--path-regex only).


btrfs restore returns a zero exit status if it succeeds. Non zero is returned in case of failure.


btrfs is part of btrfs-progs. Please refer to the btrfs wiki for further details.
