Abstract: The disclosed systems emulate high-frequency application-consistent snapshots by forming restore point data sets based on remote site replay of I/O commands. A method embodiment commences upon identifying a primary computing site and a secondary computing site, then identifying an application to be restored from the secondary computing site after a disaster. Prior to the disaster, a group of computing entities of the application to be restored from the secondary computing site are identified. Input/output operations that are performed over any of the computing entities at the primary site are streamed to the secondary site where they are stored. An I/O map that associates a time with an indication of a last received I/O command that had been performed over a changing set of computing entities is sent to the secondary site. An agent at the secondary site accesses the I/O map and the streamed-over I/Os to construct recovery data.

Abstract: A method for more efficiently utilizing storage space in a redundant array of independent disks (RAID) is disclosed. In one embodiment, such a method implements a RAID from multiple storage drives. The RAID utilizes data striping with distributed parity values to provide desired data protection/redundancy. The distributed parity values are placed on selected storage drives of the RAID in accordance with a designated parity rotation. The method further adaptively alters the parity rotation of the RAID to provide an increased concentration of parity values in certain storage drives of the RAID compared to other storage drives of the RAID. This parity rotation may be adapted based on residual storage capacity in each storage drive, consumed space in each storage drive, or the like. A corresponding system and computer program product are also disclosed.
