# [NAME](#NAME)

**era\_restore** - restore era metadata file to device or file.

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#DESCRIPTION)

**era\_restore** restores era metadata created by the respective device-mapper target dumped into an XML formatted (see [**era\_dump**(8)](/man/enterprise-packages/thin-provisioning-tools/era_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.

This tool cannot be run on live metadata.

# [OPTIONS](#OPTIONS)

[**-h, --help**](#h)

Print help and exit.

[**-V, --version**](#V)

[**-q, --quiet**](#q)

Don't print any output. Check the exit code to test for success.

[**-i, --input {xml file}**](#i)

Specify input file containing xml metadata.

[**-o, --output {device|file}**](#o)

    the metadata.
```

# [EXAMPLE](#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:

```

```
