Data backup
When planning measures to secure data, many different causes of risk have to be considered: physical disturbances like hardware malfunctions or fire, the use of deficient programs or purposefully damaging software, misuse or sabotage can lead to data loss and, in some cases, unwanted changes of data. In these cases it is imperative to be able to revert to an archival backup copy. The copy has to be compiled before the loss or unwanted change. This might date back several days.
The ZIV is using the Tivoli Storage Manager (TSM) to secure data, which deposits the backup data in a tape record system with a capacity of currently 700 TB. This service is available to all computers operated by the WWU.
Software versions and download, client registration
The most of our TSM servers currently run on version 5.5. The client versions 5.5 or 6.x (except for Windows XP, Vista und Server 2008/2003) should be used. TSM05 runs version 5.4. The client versions 5.4 or 5.5 should be used here.
The software can be purchased directly from IBM, however, the same offer is mirrored by Karlsruhe university: ftp://ftp.scc.kit.edu/pub/tsm/mirror/maintenance/client/.
We are also trying to locally keep the relevant packages: http://www.uni-muenster.de/ZIV.TSM/ADSM-Download/.
Internal regulations
There are some duties that result from using TSM that are generally derived from the precept to handle ressources responsibly. Further information can be found in the internal regulations for backup, archival and HSM service (only available in German).
