.SH DESCRIPTION
.B xfs_mdrestore
is a debugging tool that restores a metadata image generated by
.BR xfs_metadump (8)
to a filesystem. The
.I source
argument specifies the location of the metadump image and the
.I target
argument specifies the destination for the filesystem image.
If the
.I source
is \-, then the metadata image is read from stdin. This allows the output of
be another program such as a compression application to be redirected to
.BR xfs_mdrestore .
The
.I target
can be either a file or a device.
.PP
.B xfs_mdrestore
should not be used to restore metadata onto an existing filesystem unless
you are completely certain the
.I target
can be destroyed.
