Data Backup via Tivoli Storage Manager (TSM)

Please note: Some of the links below lead to pages in German as work on the English version is still in progress. We apologize for the inconvenience.

Tivoli Storage Manager (TSM) enables you to do → incremental backups of computers and to archive files.

If you are interested in using it, you may apply for access at the → hotline@uni-mainz.de. You will have to specify a permanently available e-mail address, the IP address and FQDN (Fully Qualified Domain Name) of the computer that is to be backed-up, as well as the estimated quantity of data to be backed-up.

Allgemeine Informationen

  1. Backups
  2. Archiving

Backups

Backups facilitate protection and recovery of files, for example after a disk problem or after accidental deletion of files. At the TSM server the files will be overwritten with any new version, and the previous version as well as the newest version will be provisioned on the server. If the previous version is older than 90 days it will be deleted.

If a user deletes a file on his computer, the latest version of the file will be stored on the server for 180 days and earlier versions will be deleted.

Please note: if you save a file with the same name in the same directory as the file that was previously deleted, then the backed-up latest version of the deleted file will be overwritten by the new file at the next backup.

We recommend to make a daily backup of file systems and to exclude directories with many files that change very often (scratch, tmp, ...). If the latest backup of a file system was made more than a year ago, it will be deleted by the Data Center.

Archiving

Archives are made for storing files that are currently not - or only rarely - needed. This enables you to save storage space on local storage media. Archives must be confirmed and respectively prolongated once a year. The storage time of any TSM archive may be inquired at → hotline@uni-mainz.de.

In case of a re-setting of the archive system of the university the users of the archive have to transfer the files from the old archive to a new one no later than 3 months after having been notified.
