## NAME
       **era**___**restore** - restore era metadata file to device or file.

## SYNOPSIS
       **era**___**restore** [_options_] **-i** {xml file} **-o** {device|file}

## DESCRIPTION
       **era**___**restore**  restores era metadata created by the respective device-mapper target dumped into
       an XML formatted (see **era**___**[dump**(8)](https://www.chedong.com/phpMan.php/man/dump/8/markdown)) file, which optionally can be preprocessed before the  re‐
       store  to  another device or file. If restored to a metadata device, the metadata can be pro‐
       cessed 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}
              Specify input file containing xml metadata.

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

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


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

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


## DIAGNOSTICS
       **era**___**restore** returns an exit code of 0 for success or 1 for error.
