Backup

Backup is the precautionary creation and updating of copies of the data inventory in order to permit the restoration of data lost due to operator errors such as unintentional deletion or due to hardware failures.

In HSMS V12.0A a new type of backup processing is introduced: version backup.

According to the necessity it is now possible to use any of the two types of backup processing, which have different benefits and specifics, either in parallel or alternatively:

• backup
  Provides backup of files from different storages and job variables; supports full, incremental or partial backup of files; automatic duplication of save files and automatic deletion of obsolete save files; statements BACKUP-FILES, BACKUP-NODE-FILES.
• version backup
  Ensures that a number of file versions are kept; provides only incremental backups of files; reorganization mechanism is introduced to copy still necessary file versions and to be able to remove obsolete file versions. Statements BACKUP-FILE-VERSIONS, REORGANIZE-VERSION-BACKUP, CHECK-CATALOGED-FILES.
