20150212899 | GRAPHICAL USER INTERFACE RELATIONSHIP GRAPH FOR DISPLAYING RELATIONSHIPS BETWEEN IMAGE BACKUP FILES IN A BACKUP JOB - Graphical user interface relationship graph for displaying relationships between image backup files in a backup job. In one example embodiment, one or more non-transitory computer-readable media store a program that causes a processor to generate and visually present, on an electronic display device associated with the processor, a graphical user interface (GUI) relationship graph for displaying relationships between image backup files in a backup job. The GUI relationship graph includes multiple image nodes each representing an image backup file of a source storage and a chain path including multiple links. Each of the links represents a parent-child relationship between one of the image nodes and another of the image nodes. | 07-30-2015 |
20140250080 | CHANGE TRACKING FOR MULTIPHASE DEDUPLICATION - Change tracking for multiphase deduplication. In one example embodiment, a method of tracking changes to a source storage of a source system for multiphase deduplication includes a change tracking phase that includes performing various steps for only allocated blocks in the source storage that are changed between a prior point in time and a subsequent point in time. These steps include temporarily storing a copy of the changed block in a volatile memory of the source system prior to writing the changed block to the source storage, performing a hash function only once on the copy of the changed block, while the copy is temporarily stored in a volatile memory of the source system, to calculate a hash value, writing the changed block to the source storage, and tracking, in a change log, a location in the source storage of the changed block and the corresponding hash value. | 09-04-2014 |
20140250079 | LOCAL SEEDING OF A RESTORE STORAGE FOR RESTORING A BACKUP FROM A REMOTE DEDUPLICATION VAULT STORAGE - Local seeding of a restore storage for restoring a backup from a remote deduplication vault storage. In one example embodiment, a method of local seeding of a restore storage for restoring a backup from a remote deduplication vault storage includes determining which blocks included in a backup of a source storage at a point in time, which is stored in the remote vault storage, are available in a local seeded storage containing common blocks, reading the locally available blocks from the local seeded storage, reading the non-locally available blocks from the remote vault storage, and storing the read blocks in the restore storage in the same position as stored in the source storage at the point in time. The remote vault storage is remote from the restore storage and the local seeded storage is local to the restore storage. | 09-04-2014 |
20140250078 | MULTIPHASE DEDUPLICATION - Multiphase deduplication. In one example embodiment, a method of multiphase deduplication includes an analysis phase and a backup phase. The analysis phase includes analyzing each allocated block stored in a source storage at a point in time to determine if the block is duplicated in a vault storage. The backup phase is performed after completion of the analysis phase and includes storing, in the vault storage, each unique nonduplicate block from the source storage. | 09-04-2014 |
20140250077 | DEDUPLICATION VAULT STORAGE SEEDING - Deduplication vault storage seeding. In one example embodiment, a method of seeding a deduplication vault storage includes seeding a vault storage with common blocks and storing, in the vault storage, each unique block from a source storage at a point in time that is not already duplicated in the vault storage. | 09-04-2014 |
20140164330 | PRUNING PREVIOUSLY-ALLOCATED FREE BLOCKS FROM A SYNTHETIC BACKUP - Pruning previously-allocated free blocks from a synthetic backup. In one example embodiment, a method of pruning previously-allocated free blocks from a synthetic backup includes identifying multiple sequential backups to be included in a synthetic backup, accessing a copy of a file system block allocation map (FSBAM) of the most recent of the multiple sequential backups that was stored with the most recent backup, identifying a set of blocks that includes the most recent block for each unique block position contained within the multiple sequential backups, pruning the set of blocks to exclude all blocks that are identified as being free in the FSBAM, storing the pruned set of blocks in the synthetic backup, and storing a copy of the FSBAM with the synthetic backup. | 06-12-2014 |
