Backing up to disk or Net-Storage

The data volumes requiring backup in computer centers continue to increase. Since it can be difficult to increase the number of available devices and the time available for backup, backups to disk can be of great help. While tape devices often can only be used during restricted periods, disk availability is always guaranteed. For this reason, the data is first backed up to disk or Net-Storage. Later they can then be moved to tape. Possible criteria for the move time are, for example, the availability of MTC devices or the reaching of a particular disk utilization. 

Depending on the archive type, save files are moved with the following statements:

• Backup archive: MOVE-SAVE-FILE
• Version backup archive: REORGANIZE-VERSION-BACKUP
