Backup and recovery (BUR) is the daily, weekly, or monthly occurrence of copying SAN data to tape for operational restoration if data are lost.
Backup and recovery RUs differ in the GETS legacy and transformed environments.
Legacy Backup
The GETS legacy backup environment has four possible RUs:
Resource Unit | Description | Billed By | Invoice Collection Date |
Application/Utility Tapes in Storage (Active) | Tapes currently in rotation | Tape cartridge | Last day of month |
Application/Utility Tapes in Storage (Virtual Tape Storage) | Tapes created from hard drive | Gigabyte | Last day of month |
Application/Utility Tapes in Storage (Archived) | Tapes held for retention purposes | Tape cartridge | Last day of month |
Backup retention – Disaster Recovery offsite | Tapes stored offsite | Tape cartridge | Last day of month |
Three possible legacy backup and recovery billing combinations may appear on the agency’s invoice as shown below:

Option 3, the Extended Backup in the legacy environment, occurs only when the agency has so much data that the information cannot be backed up in an allotted time. In those cases, data are moved first to virtual tapes and then transferred to actual tapes. Agencies that incur these costs may be able to reduce the amount of data stored by implementing the suggestions found in Agency Best Practices to Manage Storage Consumption of this document.
Transformed Backup
The GETS transformed backup and recovery environment has several advantages over legacy:
- Data restored from archives are platform independent.
- A formal process for tape transport and retrieval has been developed.
- Backup and recovery services are managed across the enterprise by IBM, a GETS server provider partner.
Additionally, the transformed backup and recovery RUs have been simplified:
Resource Unit | Billed By | Invoice Collection Date |
Backup and Recovery Services RU | Gigabyte | 15th day of month |
Tape Archive RU | Gigabyte | 15th day of month |
