Optimized recovery
View Patent ↗A method, article of manufacture, and apparatus for restoring data. In some embodiments, this includes determining an object to be recovered, determining a representation of the object, and requesting the representation of the object from a data resource system. In some embodiments, the representation of the object is a hash value of the object. In some embodiments, the representation of the object is a segment of the object.
1. A method for restoring data, comprising:
determining an object to be recovered from a data resource system, wherein the data resource system maintains a storage index that includes a list of hashes of stored objects that share the same content;
determining a representation of the object based at least in part on the list of hashes, wherein at least a portion of the object to be recovered shares the same content as one or more other objects stored in the data resource system, and wherein the representation of the object includes the shared content; and
determining a best data resource system based at least in part on geographic location; and
requesting the representation of the object from the best data resource system.
2. The method as recited in claim 1 , wherein the representation of the object is a hash value of the object.
3. The method as recited in claim 1 , wherein the representation of the object is a segment of the object.
4. The method as recited in claim 1 , wherein the best data resource system is determined further based at least in part on available resources.
5. The method as recited in claim 1 , further comprising receiving the representation of the object from the best data resource system.
6. The method as recited in claim 1 , wherein the object includes a plurality of sub-objects, and restoring data further comprises pinning at least one of the plurality of sub-objects, wherein pinning a sub-object includes restricting the pinned sub-object to Remote I/O during a recovery operation.
7. A system for restoring data, comprising a processor configured to:
determine an object to be recovered from a data resource system, wherein the data resource system maintains a storage index that includes a list of hashes of stored objects that share the same content;
determine a representation of the object based at least in part on the list of hashes, wherein at least a portion of the object to be recovered shares the same content as one or more other objects stored in the data resource system, and wherein the representation of the object includes the shared content; and
determining a best data resource system based at least in part on geographic location; and
requesting the representation of the object from the best data resource system.
8. The system as recited in claim 7 , wherein the representation of the object is a hash value of the object.
9. The system as recited in claim 7 , wherein the representation of the object is a segment of the object.
10. The system as recited in claim 7 , wherein the object includes a plurality of sub-objects, and the processor is further configured to pin at least one of the plurality of sub-objects, wherein pinning a sub-object includes restricting the pinned sub-object to Remote I/O during a recovery operation.
11. A computer program product for restoring data, comprising a non-transitory computer usable medium having machine readable code embodied therein for:
determining an object to be recovered from a data resource system, wherein the data resource system maintains a storage index that includes a list of hashes of stored objects that share the same content;
determining a representation of the object based at least in part on the list of hashes, wherein at least a portion of the object to be recovered shares the same content as one or more other objects stored in the data resource system, and wherein the representation of the object includes the shared content; and
determining a best data resource system based at least in part on geographic location; and
requesting the representation of the object from the best data resource system.
12. The computer program product as recited in claim 11 , wherein the representation of the object is a hash value of the object.
13. The computer program product as recited in claim 11 , wherein the representation of the object is a segment of the object.
14. The computer program product as recited in claim 11 , wherein the best data resource system is determined further based at least in part on available resources.
15. The computer program product as recited in claim 11 , wherein the object includes a plurality of sub-objects, and restoring data further comprises pinning at least one of the plurality of sub-objects, wherein pinning a sub-object includes restricting the pinned sub-object to Remote I/O during a recovery operation.
