The Novell Storage Services (NSS) File System Metadata Migration Utility (METAMIG) for OES Linux allows you to save and restore NSS file system trustee, user quota, and directory quota metadata. This utility works only with files in the NSS file system on OES Linux. It is available in OES SP1 and later.
METAMIG is located in the /opt/novell/nss/sbin/metamig directory.

|
Option |
Description |
|---|---|
-m, --meta=mask
|
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. For example, if the NCP Server has been turned off and its database is not yet resynchronized with the volume, do not use this command option until the database is again current. |
The following options are options available to actions related to restore.
|
Option |
Description |
|---|---|
-m, --meta=mask
|
The types of metadata to be restored. If a value is not specified, it defaults to all. For information, see Mask. |
-f, --filter=regexp
|
A filter that restores only files and directories that match the specified regular expression. Use a regular expression to specify one or more files and directories to be restored. For example, to set criteria to restore only files with names that start with the letter “a”, use this option:--filter=.*\\a.* Please refer to a programming textbook or search the Internet for information about how to construct regular expressions. |
-t, --tree=treename
|
If this value is specified, this setting overrides the saved directory treename. |
-d, --details |
Displays all actions taken. |
The mask is a string of characters with each character representing a type of NSS file system metadata. Use the mask to specify values for the meta parameter in SOptions (Save) and ROptions (Restore).
To save the user quota data and directory quota data for a volume called VOL1 in the /backup/volquotas file, enter
metamig save VOL1 -m ud >/backup/volquotas
To restore the user quota data from the file /backup/volquotas to VOL1, enter
metamig restore VOL1 -m u </backup/volquotas
