Glossary

  • Active Data: Data located in the backup system that match the database in your system. This data is not saved again. When a file is changed or deleted in your system, it acquires the status "inactive" in the backup system. If you have created a modified version of the file it backed up again. The new backup file is given the status "active".
  • Archiving: describes the long-term (yearly) retention of data that is bound to strict rules (such as immutability, long-term retrieve-ability and playback capability).
  • Directed Recover: refers to the recovery data of another computer or client.
  • Inactive Data: is the data that no longer on the hard disk of the backup client (or on your machine). In order to restore this, a special option in the restoration must be specified.
  • Incremental backup: TSM backs up incrementally. This means only data that has changed since the last backup will be transferred to the backup server during each backup.
  • Incremental  forever:  as IBM refers to the process, only changed data is secured in each backup and applies this method for life on a computer. Thus TSM works very efficiently with its resources.
  • configuration files: In Windows, all the client-configurations are in one file, dsm.opt. Under Unix, there is the dsm.opt and dsm.sys file, which must be adjusted accordingly to the client needs. This includes all specific network addresses and network ports included.
  • Management class:  TSM is used to set different storage periods. For example, Log files can expire sooner than development or documentation data. A storage period of 180 days is set as default. Setting a specific management class takes place during the configuration of the client.
  • Schedule: If an automatic backup is performed, the client has a backup plan (Schedule). The client remembers this "plan" asks the server at the appropriate time to start its backup.
  • Scheduler: Process or service managing the automatic back up on your computer.
  • Selective backup: In special cases, a file needs to be continuously backed up, even if the criteria for an incremental backup are not met. "tsm>selectiv/ home / myfile" ensures this happens.
