The Division of Information Technology (DIT)  at the University of Maryland offers data backup services to the campus research, academic and administrative community in the hopes of consolidating and enforcing data protection best practices at a competitive cost.  The backup service is a locally hosted service running IBM’s Tivoli Storage Manager.  With this product, we are able to provide daily incremental-forever data backup operations for registered computers whether those computers are servers or workstations.   When you register for backup services with the DIT, we will configure your backup access according to the data retention and storage management policies you select.  Such policies have been engineered with UMD-specific requirements and Disaster Recovery best practices in mind, so you can fully be sure that your backup data is protected, secured and restorable at all times. 

The data backup service is available for university research, academic and administrative departments and affiliates.  The data backup service is a chargeable service. As such, a valid KFS number is required for service per registered machine.

Standard Service Options:

When registering a machine for backups, you have to select your service options with respect to backup retention and storage management.  The options and explanations are listed below.

Data Backup Service Retention settings

TSM backup policies for data retention will organize and back up data nightly for all registered machines.  There are four retention-levels from which to choose.  When registering a machine for backups, you should elect one of the four retention levels as a default setting. The chart and definitions below define those retention levels.

  •  Versions Data Exist:  How many copies to keep while maintaining the client data while on the client machine.
  •  Versions Data Deleted: How many copies to maintain the client data after it is deleted from the client machine.
  •  Retain Extra Versions:  How many days to maintain inactive data.
  •  Retention Only Versions: How long to maintain the last version of the client data after it has been deleted from the client machine.

Storage Management Tier Options:

There are two different storage management tiers from which to choose. Select one for your default tier. The tiers are defined below:

Tier 0:  If you select the tier 0 storage management option, all backup data will be replicated to a second data center on campus and a third, encrypted copy will be generated for offsite vaulting with our tape vaulting vendor. Data that is very specific and not easily reproduced will be good candidates for Tier 0 service.  Financial records, research data, intellectual property records and other critical data are examples for which we would recommend Tier 0 storage management.

Tier 1:  If you select tier 1 storage management options, only the most recent backup data will be replicated to a second data center.  A third copy offsite is not guaranteed.  Should there be a failure of the primary TSM backup server, historical backup data will be lost.  Only the most recent existing data will be available for restore.   If you do not have a need to retain offsite records or your data is generally non-changing, tier 1 will provide a cost-effective backup method.  Data not subject to federal, state or university regulations are also viable candidates for Tier 1 management.
