  • Publication number: 20240053906
    Abstract: A degree of fragmentation is determined based on a number of holes present in a storage system layout or a portion of a layout. Edges between the holes and used portions of the storage system are tabulated by scanning a storage space. The occurrences of a pattern of used/available allocation units and/or the occurrences of another pattern available/used allocation units are recognized. A fragmentation value is calculated based on occurrences of the patterns in view of the total storage space. The present fragmentation measurement system utilizes the number of occurrences of the holes in assessing fragmentation.

  • Patent number: 10769022
    Abstract: Disclosed is an improved system, method, and computer program product for generating backups in a database system. This is accomplished by using a disaster recovery infrastructure of a database system to generate the database backup, where the backup activities are performed on a standby database system, thereby freeing up the primary database system. To avoid authorization/authentication requirements between the primary and standby that may require human intervention to type passwords when backups are performed on the standby, a backup solution is provided that does not require human intervention to enter passwords when automating the backup process.
