DESCRIPTION
thin_restore restores thin provisioning metadata created by the respective
device-mapper target dumped into an XML formatted (see thin_dump(8)) file,
which optionally can be preprocessed before the restore to another device or
file. If restored to a metadata device, the metadata can be processed by the
device-mapper target.
This tool cannot be run on live metadata.
