btrfs restore [options] <device> <path> | -l <device>DESCRIPTION
btrfs restore is used to try to salvage files from a damaged filesystem and restore them into path or just list the subvolume tree roots. The filesystem image is not modified.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/Restore

- -r|--root <rootid>

- dry run (only list files that would be recovered)
- --path-regex <regex>
- restore only filenames matching a regular expression (regex(7)) with a mandatory format ^/(|home(|/username(|/Desktop(|/.*))))$ The format is not very comfortable and restores all files in the directories in the whole path, so this is not useful for restoring single file in a deep hierarchy.
