btrfs restore

Try to salvage files from a damaged btrfs filesystem.

• 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}
