Server Backup Policy and Retention Schedule

Purpose

The purpose of the ITS Server Backup Policy is to provide clarity about backups, define the roles and responsibilities for backup creation, restoration and verification of data on systems managed by Information Technology (ITS), whether hosted in the Wickes Hall Data Center or South Campus Complex B Data Closet. 

Policy / Procedure

General Information

Server backups run nightly.

Servers will be backed-up per the ITS Server Backup Category and Retention Schedule.

Backup verification is detailed in the Backup Verification Schedule contained in this document.

Systems not maintained by ITS will not be backed-up unless arrangements are made.

New ITS maintained servers will be put in their appropriate Server Category based on the ITS Server Backup and Retention Policy at creation. 

It is important to understand that the backup retention period is not the same as the document retention period.  See the Definitions section in this document for additional information.

Cloud Backups

  • Azure cloud servers are not backed up.
  • AWS cloud servers are not backed up.  There are currently two AWS servers, an outside vulnerability scanning tool and www.svsu.edu webserver (used during known campus internet outages) that can be rebuilt if needed.
  • O365 cloud products are not backed-up by ITS.  For SharePoint/OneDrive for Business Preservation Hold is turned on and in extreme cases a file could be recovered.  However, it is not the intention to use Preservation Hold as the backup.

AIS4 is backed up as Diamond.  Yearly backup is kept for 7 years.  Yearly backup happens on the second Monday of December at 4:00AM.

Bronze - test systems that should not need to go back more than 7 days.

Silver - systems with limited changes

Gold - base protection of key servers.  If it is broke, we should know before the 31-day expiration.

Platinum - ditto Gold, with longer retention.

Diamond - Critical systems that are key to University Business.

Backup Schedule

Backups are verified on a random rotating basis each month per the following table.

File Servers

 

 Month 1

 Month 2

Application Server

Critical Application Server

Pre-Production

 Month 3

The verification will be done in a 3-month cycle. The server categories have been divided evenly between the 3 months and a server will be chosen out of each category to be verified.  At the end of 3 months the process will start over and a different server will be picked out of each category.

If a server is found not to be backed up or a successful restore is not possible, proper steps will be made to ensure the server starts being backed up or future restores will be successful.
