## NAME
       **cache_restore **- restore cache metadata file to device or file.

## SYNOPSIS
       **cache_restore **[_options_] **-i **{xml file} **-o **{device|file}

## DESCRIPTION
       **cache_restore  **restores  cache metadata created by the respective device-mapper target dumped
       into an XML formatted (see [**cache_dump**(8)](https://www.chedong.com/phpMan.php/man/cachedump/8/markdown)) 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.

## OPTIONS
### -h, --help
              Print help and exit.

### -V, --version
              Print version information and exit.

### -q, --quiet
              Don't print any output.  Check the exit code to test for success.

### -i, --input {xml file}
              Input xml.

### -o, --output {device|file}
              Output file or device for restored binary metadata.

           If a file is used thin it must be preallocated, and large enough to hold
           the metadata.


### --metadata-version {1|2}
              Choose a metadata version.

## DEBUGGING OPTIONS
### --debug-override-metadata-version {integer}
              Override the version stored in the metadata.

### --omit-clean-shutdown
              Don't set the clean shutdown flag.

## EXAMPLE
       Restores the XML formatted cache metadata on file metadata to logical volume /dev/vg/metadata
       for further processing by the respective device-mapper target:

           $ cache_restore -i metadata -o /dev/vg/metadata


## DIAGNOSTICS
       **cache_restore **returns an exit code of 0 for success or 1 for error.
