    摘要: A method is disclosed for automatically reconciling the client and server databases and actively management the files stored in the cache. The method monitors free space on a DASD so that a VTS is allowed to fill the DASD with data during a reconcile process. Furthermore, an active cache filename management scheme is provided that improved VTS performance by obtaining information on premigrated files thereby eliminating usage of a premigration candidate list.

    摘要: A data storage system provides a method and apparatus for preserving consistency between a database back-up and a set of storage volumes. The system includes a storage manager, or storage controller, interconnected to a plurality of storage volumes, a drive, and a database storage. The storage manager receives data files from an attached data processing unit. The storage manager directs the data files such that the files are written to a selected storage volume loaded into the drive. The storage manager maintains reference information and storage volume location information for each data file in the database storage. The storage manager detects a volume full condition when the storage media approaches a predetermined position prior to the physical end of the volume. The storage manager generates a back-up copy of the current database, transfers the database back-up to the drive, and directs the drive to write the database back-up onto the selected storage volume. Thus, each selected storage volume contains a database back-up which remains consistent with the data files currently stored on the selected storage volume and previously stored on previously selected storage volumes.

    摘要: Computer program product to back up deduplicated data to data storage media, the deduplicated data comprising a plurality of data blocks referenced for deduplication. In one embodiment, the existence of multiple references to each of the data blocks is determined; and at least two copies of at least each data block having multiple references thereto is stored, each to a separate data storage media. In another embodiment, the references to each of the data blocks is determined; the total of multiple references is compared to a percentage threshold; and multiple copies are stored for all the data blocks where the percentage threshold is exceeded.
