BTRFS-RESTORE(8) Btrfs Manual BTRFS-RESTORE(8)
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.
