# btrfs restore
> Try to salvage files from a damaged btrfs filesystem.
> More information: <https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs-restore>.
- Restore all files from a btrfs filesystem to a given directory:
`sudo btrfs restore {{path/to/btrfs_device}} {{path/to/target_directory}}`
- List (don't write) files to be restored from a btrfs filesystem:
`sudo btrfs restore --dry-run {{path/to/btrfs_device}} {{path/to/target_directory}}`
- Restore files matching a given regex ([c]ase-insensitive) files to be restored from a btrfs filesystem (all parent directories of target file(s) must match as well):
`sudo btrfs restore --path-regex {{regex}} -c {{path/to/btrfs_device}} {{path/to/target_directory}}`
- Restore files from a btrfs filesystem using a specific root tree `bytenr` (see `btrfs-find-root`):
`sudo btrfs restore -t {{bytenr}} {{path/to/btrfs_device}} {{path/to/target_directory}}`
- Restore files from a btrfs filesystem (along with metadata, extended attributes, and Symlinks), overwriting files in the target:
`sudo btrfs restore --metadata --xattr --symlinks --overwrite {{path/to/btrfs_device}} {{path/to/target_directory}}`
