Shared Infrastructure Group provides backups for servers on campus using EMC NetWorker (formerly Legato Networker). Currently, we are licensed to back up most versions of Windows, Linux and Unix.

The system administrator for the box is responsible for:

  • Installing and configuring the EMC client
  • Being familiar with backup strategies and recovery procedures
  • Referring to the EMC Disaster Recovery Guide for detailed information.

Service Details

Our backup server is a Dell R510 running Oracle RedHat Linux and Networker 8.1sp1

Our window for backups is to start every night at midnight. Full backups are generally scheduled to happen on weekends to avoid impacting customers. Sysadmins may choose a preferred backup schedule.

Using NetWorker - Frequently Asked Questions

How do I install or use the client software?
Follow the links in the table above to the NetWorker documentation for your platform. Also, you should read the EMC Disaster Recovery Guide and be familiar with what is involved in restoring your server.

Why am I getting this error when I run the EMC client?
If you get an error message when trying to open the NetWorker user program saying that the server cannot be found, or that the media database cannot be opened, you will need to specify the backup server to use like this:

Windows: c:\program files\nsr\bin\winworkr.exe -s
