Server Backup

Backup costs are published in the OSU internal fees. Select "Information Services" and "IT Infrastructure Services".

Information Services offers data backup services to the campus academic and administrative community.  The backup service is a locally hosted service running on enterprise class hardware.  We are able to provide daily incremental, differential and full backups for registered servers.

Service Details

Information Services 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 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.

Backups are started every night at midnight. Full backups are generally scheduled to happen on weekends to avoid impacting customers. Sysadmins may choose a preferred backup schedule.

Installing the Client

When installing the client, make sure to specify the Networker server name as

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
Linux/Unix: /usr/bin/recover -s
