Dell NetWorker 19.9 Administration Guide

Compressing the media database

You can free up more space on the server by compressing the media database.

1. Delete the appropriate file:

   • On Windows:

     NetWorker_install_dir\mm\cmprssd

   • On UNIX:

     /nsr/mm/.cmprssd

2. Type the following command at the command prompt:
   nsrim

   When we perform the compression on a SQLite media database, SQLite in the background creates a copy of the SQLite database in a temporary space. After the compression is complete, the copy in the temporary space gets deleted. You can configure the temporary space that the SQLite uses on the host machines. It uses the temporary path of the system by default.

   When you install NetWorker on your system the following paths are set by default:

   • /nsr/tmp on Linux during the NetWorker installation.
   • <nw_install_path>/nsr/tmp on Windows when the nsrmmdbd starts after the NetWorker installation.

   The paths can be modified as follows:

   • On Windows, the system environment variable MMDB_SQLITE_TMP can be set to the desired path as required by the user.
   • On Linux, the environment variable SQLITE_TMPDIR can be modified by updating the same in nsr_serverrc file.
     NOTE:In both cases, stop the NetWorker services, make the changes and start the services again.
