Abstract: Facility for providing backup and restore of all data center components including physical machines, virtual machines, routers, networks, sub-networks, switches, firewall, directory lookup, DNS, DHCP and internet access. Virtual or physical machines are associated to data center components and a software defined network, storage, and compute infrastructure is provided.

Abstract: Facility for transferring data over a network between two network endpoints by transferring hash signatures over the network instead the actual data. The hash signatures are pre-generated from local static data and stored in a hash database before any data is transferred between source and destination. The hash signatures are created on both sides of a network at the point where data is local, and the hash database consists of hash signatures of blocks of data that are stored locally. The hash signatures are created using different traversal patterns across local data so that the hash database can represent a larger dataset then the actual physical storage of the local data. If no local data is present, then arbitrary data is generated and then remains static.

Abstract: A system for progressive just-in-time restoration of data from backup media. Backup data may be divided into a plurality of chunks and stored on any kind of media such as a direct attached storage (DAS) disk, object storage, USB drive, network share or tape. An index map is maintained that indicates the location of each of the plurality of chunks in cloud storage, the index map representing contiguous blocks of backup data of a volume. The backup data may be compressed, encrypted, or de-duplicated. The backup data may be located on different media, object stores, or network shares, or at differing geographic locations. To perform a recovery, a virtual LUN or virtual volume is mounted and provided to the operating system and applications of the restored computer. Chunks may be progressively copied from cloud storage to a data cache and restored in response to requests for blocks.

Abstract: Facility for using images created by backup software to recreate an entire machine as it was at the point in time in the past when the backup was taken. The facility can be extended so as to bring up a set of machines which together serve some logical business function as in a cluster or federated servers, and further extended so that an entire data center may be virtualized from backup images. The virtualized servers provided may serve as an alternate data center standing in case of disaster or to meet maintenance windows achieving low cost Instant Disaster Recovery. A set of virtual machines may stand in for physical machines for a period of time and then resynchronized or re-seeded to physical machines via a combination of bare metal recovery and re-synchronizing from live LUNs that form the virtual machine disks.

Abstract: High performance, enterprise-level data protection system and method provides efficient block-level incremental snapshots of primary storage devices, and instant availability of such snapshots in immediately mountable form that can be directly used in place of the primary storage device. Related systems and applications are described, including an “Enterprise Image Destination” (EID) for backup images; a mirroring technique whereby a replacement physical primary facility may be created while working with a second storage unit as the primary source file system; and a technique for eliminating redundant data in backup images when multiple systems with partially common contents (e.g., operating system files, common databases, application executables, etc.) are being backed up. A number of examples showing “Fast Application Restore” (FAR) with the use of the invention are also provided.

Abstract: Methods and software are provided for “hot migration” of data an original storage unit for a target system to destination storage unit. In one embodiment, a virtual storage device is provided, having a control block mapped to both the original storage unit, as well as to the destination storage unit. The target system is stopped, the virtual storage device is substituted for the original storage unit, and the target system is restarted. The virtual storage device directs requests to the destination storage unit, and fulfills read requests from whichever of the two storage units has a valid copy of data requested (depending, e.g., on whether the data is as yet unchanged, has been re-written, or has been copied, during the migration process). Unchanged data blocks are copies from the original storage unit to the destination storage unit. The target system is stopped, the virtual storage device is disconnected from the target system, and the destination storage unit is connected in its place.
