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.
|
|
|
|
NOTE: It is recommended to read the following btrfs wiki page if your data is
|
|
not salvaged with default option: +
|
