Data Storage & Servers
Backup
UCIT provides the University of Cincinnati with a state of the art backup service including the following components:
- IBM’s Tivoli Storage Manager (TSM) running on an AIX P750 system backing up 4TB nightly.
- EMC Data Domain DD880 Data Deduplication Storage System with a capacity of 600TB.
- STK SL8500 Automatic Tape Library with a capacity of 2500 Tape cartridges.
UCIT currently houses over 400TB of data for the University of Cincinnati. By utilizing state of the art data deduplication, we work to keep costs down and service levels up. By utilizing Virtual Tape Libraries (VTL), we have the capabilities of providing virtual tape drives to our co-locators housed in our data center thereby providing the highest possible backup and restore speeds. If you choose to use our TSM system, we will provide administration and support of your data, monitor performance and ensurea level of quality service. If you opt to utilize your own backup software, let us provide virtual tape storage allowing you to concentrate on your backup administration without worrying about tape rotations or tape resources.
What is TSM backup software?
Tivoli Storage Manager (TSM) is an enterprise software program that backs up a copy of the data stored on your computer/server to a central server designed for backups. Your computer/server must be connected to the network, have adequate disk space for installation and be running an operating system that is supported by the TSM software.
What backup services are offered?
TSM offers both backup and archive services.
The two processes work independent of each other. You can both archive and backup a file; however how the TSM server handles the file very different for backup and archive.
The backup process is used to save data that is modified frequently, such as an active operations system partition or data store, and allows you to save different versions of the same file. Should the on-server version of the file become corrupted or inaccessible, you can restore to a pervious version of a backed up file; mulitple copies of the file may be available, depending on the limits set by the storage policy you negotiate with UCIT for your data. TSM sets a backup limit on how many versions of each file are kept on the TSM server, and when that backup limit is reached, the next backup process will overwrite the oldest version of a file with the new backup version to keep within the backup limit.
Archiving is a one-time snapshot of a file or object in its present state, without versioning. The archive service is generally used for long-term retention of data that is not being modified but must be retained by the user as a permanent record.
