Remote office duplication

摘要

Remote office deduplication comprises calculating one or more fingerprints of one or more data blocks, sending the one or more fingerprints to one or more backup servers via a network interface, receiving from the one or more backup servers an indication of which one or more data blocks corresponding to the one or more fingerprints should be sent to the one or more backup servers, and if the indication indicates one or more data blocks to be sent to the one or more backup servers, sending the one or more data blocks to the one or more backup servers via the network interface.

1. A method comprising:
calculating a real-time deduplication rate for data blocks transferred between one or more backup clients and one or more backup servers via a network interface, the deduplication rate comprising a percentage of data blocks required for a backup operation transferred to the one or more backup servers prior to the backup operation; disabling the sending of fingerprints from the one or more backup clients to the one or more backup servers if the sending is currently enabled and the deduplication rate is less than a first threshold, each of the fingerprints identifying a data block and for use in determining whether the data block associated with the fingerprint should be sent to the one or more backup servers via the network; and enabling the sending if the sending is currently disabled and the deduplication rate is greater than a second threshold.
