SYNCHRONIZATION OF STORAGE USING COMPARISONS OF FINGERPRINTS OF BLOCKS |
| 摘要 |
A system for processing data includes a data storage device and a processor. The data storage device stores a set of data. The processor is configured to divide the set of data in the data storage system into a set of segments; compute a set of fingerprints, wherein the set of fingerprints comprises a fingerprint for each segment of the set of segments; store the set of fingerprints in a new snapshot; identify a second set of fingerprints in the new snapshot that are not already in a fingerprint index; cause a second set of segments associated with the second set of fingerprints to be stored in a backup data storage system; and cause the second set of fingerprints to be added to the fingerprint index. |

1. A system for processing data comprising:
a data storage device, wherein the data storage device stores a set of data; and a processor is configured to:
divide the set of data in the data storage device into a set of segments;compute a set of fingerprints, wherein the set of fingerprints comprises a fingerprint for each segment of the set of segments;store the set of fingerprints in a new snapshot;identify a second set of fingerprints in the new snapshot that are not already in a fingerprint index;cause a second set of segments associated with the second set of fingerprints to be stored in a backup data storage system; andcause the second set of fingerprints to be added to the fingerprint index. |
