NAME

*thin_restore *- restore thin provisioning metadata file to device or file.

SYNOPSIS

  thin_restore [options] -i {xml file} -o {device|file}

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.
