The NSS File System Metadata Migration Utility (METAMIG) for Linux allows you to save and restore NSS file system trustee, user quota, and directory quota metadata.
METAMIG is located in the /opt/novell/nss/sbin/metamig directory.
metamig [OPTIONS]
metamig save volume [SOPTIONS]
metamig restore volume [ROPTIONS]
The first argument indicates the action to be taken on the specified NSS volume. Possible actions are Save and Restore.
|

Description |
|---|---|
save |
Saves the indicated metadata to stdout. |
restore |

The second argument specifies the NSS volume name to be saved or restored.
The third argument specifies the path to a file. This is the file to be created on save, or the file to be restored from on restore.

The types of metadata to be saved. If a value is not specified, it defaults to all. For information, see Mask. |
-n, --ncp |
Saves the trustee metadata from the NCP Trustee database instead of parsing the volume to generate the data. Use this option only if you are confident that the NCP Trustee database is available and current.
