How To Export the NetWorker Media Database Using nsrmmdbasm

The NetWorker server media database (mm) stores information about all backup and clone operations. You can export the mm into an External Data Representation (XDR) file. This file may be requested by NetWorker support when troubleshooting an issue.

The mm is also collected during an NSRGET collect: NetWorker: How to Use the NSRGet NetWorker Data Collection Tool

nsrmmdbasm may be invoked to backup the media database to an encoded file, or recover from that file later to a running NetWorker server.

This tool is not intended for common Administrator use. Do not use it unless directed to do so by Dell NetWorker Support.

Backing up the media database (Linux):

sudo nsrmmdbasm -s /nsr/mm/mmvolrel > /tmp/mm_`date -I`.xdr

nwserver:~ # nsrmmdbasm -s /nsr/mm/mmvolrel/ > /tmp/mm_`date -I`.xdr
nwserver:~ # ls -lhd /tmp/mm_2024-05-21.xdr
-rw------- 1 root root 250K May 21 16:54 /tmp/mm_2024-05-21.xdr

Backing up the media database (Windows):

nsrmmdbasm -s "{absolute path to mmvolrel}" > "{output location path}\mm.xdr"

C:\Windows\system32>nsrmmdbasm -s "C:\Program Files\EMC NetWorker\nsr\mm\mmvolrel" > C:\temp\mm_%DATE:~10,4%%DATE:~4,2%%DATE:~7,2%.xdr

C:\Windows\system32>dir C:\temp | findstr mm
