Abstract: According to embodiments described herein, a backup server maintains backup data for a set of data, which includes data for a first block and a second block. Backup data for the first and second block include backup data for a plurality of versions of the first and second block. A distinct watermark is stored for each version of the first block and each version of the second block. In response to a request to perform a restoration operation on the set of data, a particular version of the first block and a particular version of the second block are selected to use in the restoration operation by comparing a restoration target with the watermarks of the version of the first block and second block. The selected version of the first block has a different watermark than the selected version of the second block.

Abstract: A method, apparatus, and system for centralized tape management are provided for databases. A centralized availability machine or disk and tape backup server maintains working backup data for a plurality of database management systems (DBMSs) based on receiving, from each of the plurality of DBMSs, differential incremental updates. The updates may be at the database block level, with an index maintained to identify different versions of the blocks for snapshot recovery. The availability machine then determines a utilization schedule for distributing the working backup data to a plurality of tapes using a plurality of tape drives, and stores the working backup data as archived backup data on the plurality of tapes according to the utilization schedule. By placing each DBMS within a protection policy that indicates criteria to meet business goals with respect to tape backups, the utilization schedule can automatically schedule tape backup jobs with optimized hardware resource assignments.
