NAME

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

SYNOPSIS

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 tree roots.

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