The filesystem +image is not modified. +.sp +If the filesystem is damaged and cannot be repaired by the other tools +(\fI\%btrfs\-check(8)\fP or \fI\%btrfs\-rescue(8)\fP), +\fBbtrfs restore\fP could be used to +retrieve file data, as far as the metadata are readable. The checks done by +restore are less strict and the process is usually able to get far enough to +retrieve data from the whole filesystem. This comes at a cost that some data +might be incomplete or from older versions if they\(aqre available. +.sp +There are several options to attempt restoration of various file metadata type. +You can try a dry run first to see how well the process goes and use further +options to extend the set of restored metadata. +.sp +For images with damaged tree structures, there are several options to point the +process to some spare copy. +.SH OPTIONS +.INDENT 0.0 +.TP +.B \-s|\-\-snapshots +get also snapshots that are skipped by default +.TP +.B \-x|\-\-xattr +get extended attributes +.TP +.B \-m|\-\-metadata +restore owner, mode and times for files and directories +.TP +.B \-S|\-\-symlinks +restore symbolic links as well as normal files +.TP +.B \-i|\-\-ignore\-errors +ignore errors during restoration and continue +.TP +.B \-o|\-\-overwrite +overwrite directories/files in \fIpath\fP, e.g. for repeated runs +.UNINDENT +.INDENT 0.0 +.TP +.BI \-t \ <bytenr> +use \fIbytenr\fP to read the root tree +.TP +.BI \-f \ <bytenr> +only restore files that are under specified subvolume root pointed by \fIbytenr\fP +.UNINDENT +.INDENT 0.0 +.TP +.B \-u|\-\-super <mirror> +use given superblock mirror identified by <mirror>, it can be 0,1 or 2 +.TP +.B \-r|\-\-root <rootid> +only restore files that are under a specified subvolume whose objectid is \fIrootid\fP +.UNINDENT +.INDENT 0.0 +.TP +.B \-d +find directory +.UNINDENT +.INDENT 0.0 +.TP +.B \-l|\-\-list\-roots +list subvolume tree roots, can be used as argument for \fI\-r\fP +.TP +.B \-D|\-\-dry\-run +dry run (only list files that would be recovered) +.UNINDENT +.INDENT 0.0 +.TP +.BI \-\-path\-regex \ <regex> +restore only filenames matching a regular expression (\fBregex(7)\fP) +with a mandatory format +.sp +\fB^/(|home(|/username(|/Desktop(|/.*))))$\fP +.sp +The format is not very comfortable and restores all files in the +directories in the whole path, so this is not useful for restoring +single file in a deep hierarchy. +.TP +.B \-c +ignore case (\fI\-\-path\-regex\fP only) +.UNINDENT +.INDENT 0.0 +.TP +.B \-v|\-\-verbose +(deprecated) alias for global \fI\-v\fP option +.UNINDENT +.sp +\fBGlobal options\fP +.INDENT 0.0 +.TP +.B \-v|\-\-verbose +be verbose and print what is being restored +.UNINDENT +.SH EXIT STATUS +.sp +\fBbtrfs restore\fP returns a zero exit status if it succeeds.
