A Simple Example of EMC Networker Customized Backup Command

Recently I got a task to run a command or script to delete files in a given folder after a success backup. In general, there are two major ways, one way is to use PowerShell script and include Networker backup command, and the other way is to use EMC Networker customized backup command. I chose to use the second way because it is more closely integrated with Networker and easier to manage and monitor.

I follow the steps as below:

  • Step 1: In the client host, create a file save001.bat under c:\Program Files\EMC NetWorker\nsr\bin.
  • Step 2: Use txt editor to edit the Save001.bat with the script listed in the following post.

EMC Networker SQL Flat File Recovery

From EMC Networker Module for Microsoft (NMM) version 9.1, EMC introduces the new feature “SQL Flat File Recovery”, no exciting, but really a helpful feature for the DBA and Backup admin.

Before EMC Networker NMM version 9.1, the MS SQL database only can be recovered to the SQL database, either to the original database or a different database. Since SQL database and Networker are usually managed by different teams, restoring directly to the database increases the internal communication between different teams to get the task done correctly. By introducing “SQL Flat File Recovery”, Networker admin can recover the database flat file to the desired location and DBA can recover the flat file to SQL database after that at any time.

NMM 9.1 can be used with Networker server version 8.2.3 or later with some limitations stated in the administrator guide.
