Abstract: Data protection aware data migration in distributed systems is disclosed. While actively migrating data from a source to a target, the process of protecting the data is performed with respect to a recovery system. Thus, data is replicated to both the target and the recovery system. During a final phase, synchronization data is sent to both the target and the recovery system. After transmitting the synchronization data, replication or migration then between the source and the target and between the source and the recovery system ceases. The target then synchronized with the recovery system based on the synchronization data and begins operation as a new source. The old source, from which the data was migrated to the new source, may be decommissioned.

Abstract: A computer-implemented method for enabling efficient access to incremental backups may include selecting an incremental backup of a volume of data, the incremental backup of the volume of data storing blocks from the volume of data that have changed since a previous backup of the volume of data, identifying block metadata for the incremental backup that describes a location of each block within the blocks in the incremental backup, detecting synthesized block metadata for the previous backup that describes a location of each block in the volume according to a synthesized view of the volume of data from a full backup of the volume up to the previous backup, and combining the block metadata for the incremental backup with the synthesized block metadata for the previous backup to generate new synthesized block metadata for the incremental backup. Various other methods, systems, and computer-readable media are also disclosed.
