SYNOPSIS

9       cache_restore [options] -i {xml file} -o {device|file}
10
11

DESCRIPTION

13       cache_restore restores cache metadata created by the respective device-
14       mapper target dumped into an XML formatted  (see  cache_dump(8))  file,
15       which  optionally can be preprocessed before the restore to another de‐
16       vice or file.  If restored to a metadata device, the  metadata  can  be
17       processed by the device-mapper target.
18
19       This tool cannot be run on live metadata.
