DESCRIPTION
|
|
|
|
|
cache_restore restores cache metadata created by the respective device-mapper
|
|
|
|
|
target dumped into an XML formatted (see cache_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.
|
