Tivoli Storage Manager
Tivoli Storage Manager (TSM) is a file backup service run by AIT for Penn State Faculty and Staff. TSM is a remote file backup service for files on a server, workstation or personal computer. The backed up data remains available in the event of component failure, accidental deletion, file corruption or other inhibiting factors.
TSM services are available to faculty and staff here at Penn State for a minimal cost that is determined by the amount of storage used on the server. To request TSM, faculty or staff must fill out the TSM Authorization Form, and must have an ITS Charge Account in order for the TSM charges to be billed. Applications should be sent to the appropriate Dean's office as well as to the Computer Accounts Office (Room 204 Wagner Building). Requested TSM services will expire on the termination date specified. All use on the authorized account will be billed on a monthly basis in accordance with procedure. Existing TSM subscribers, or supervisors, can request additional nodes by contacting the Accounts Office at firstname.lastname@example.org; be sure to include your requested node name and existing charge account number.
When performing a backup, data will get classified in either an 'active' or 'inactive' categorization, and the number of active and inactive files is determined by the management class. The default TSM management class here at Penn State is configured so you will have at most 1 active file and 3 inactive files stored on the server. An active file is from the most recent backup performed, whereas inactive files are from a prior backup, which were once classified as active, but then changed prior to an additional backup. The time span active and inactive files are present will vary according to the frequency of your backups. For instance, if a file is updated and backed up 5 times in one day, the 4 newest backups will remain within TSM as 1 active file and 3 inactive files. The inactive versions can be retrieved if necessary through the TSM client.
Because of how the server treats active and inactive files, it is possible to have much more data on the server than you might originally have on the node you are backing up. This is dependent on how often the files change on the client, and the frequency of the backups.
Archiving stores your files within the same system, but categorizes them in a different manner. Upon choosing the 'archive' option, the file or files to be archived will always be kept in their current state. Newly created archives do not affect pre-existing archives, therefore, once created they will remain until manually deleted by the user. It is possible to have an unlimited number of archives as they are manually managed by the user, not the server.
TSM allows automatic scheduled backup of your files at a defined time. Since automatic backups require additional configuration, please contact email@example.com to request association with a schedule. When requesting an association with a schedule, please include your node name, time to back up, and frequency (daily, weekly, etc.) which you would like the automatic backups to take place. Please note that automatic backups will not run without first corresponding with us.
TSM services may be deleted in part or in their entirety from an ITS Charge Account using the TSM Deletion Form. Due to the vital nature of computer backups, TSM services will be billed to ITS Charge Accounts beyond their expiration date until explicitly cancelled using the TSM Deletion Form. If you have questions or need assistance with the application form, contact the ITS Computer Accounts Office via e-mail at firstname.lastname@example.org or by phone at 814-865-4772.
