## DESCRIPTION

Use the **evms\_metadata\_backup** utility to save a copy of all the metadata that are used to build the segments (partitions), regions, containers (groups), and volumes in the system. The metadata are saved in a file named "evms-metadata-yyyy-mm-dd-hh.mm.ss", where "yyyy-mm-dd-hh.mm.ss" is the time of the backup.

## OPTIONS

The following options can be used with **evms\_metadata\_backup**:

- \-d, --debug-level debug\_level

  Specify the amount of information that should be written to the log file. A numerical value between 0 and 9 can be specified, where a larger number generates more logging information. The following text values are also allowed:

  ```
  critical
  serious
  error
  warning
  default
  details
  entry_exit
  debug
  extra
  everything
  ```

  "Critical" generates the least information and "everything" generates the most information. The default debug level is "default" or "5."

- \-l, --log-file log\_file\_name

  Specify the location of the log file. The default value is */var/log/evms-engine.log*.

- \-n, --node-name node\_name

  Specify the node in the cluster on which the backup should be performed. The default value is the local node. If EVMS is not running in a cluster, this option is ignored.

- \-q, --quiet

  Display only error messages.

- \-v, --verbose

  Display verbose status information about the progress of the backup.

- \-h, -?, --help

  Display a summary of the options available for **evms\_metadata\_backup**.

## PARAMETERS

- directory

  Save the metadata backup file in this directory. The default directory is */var/evms/metadata-backups/*. The directory can also be set with the "metadata\_backup\_dir" variable in the "engine" section of */etc/evms.conf*.
