Abstract: A method for deduplicating at a global server for multiple storage servers includes receiving, from a storage server, a request to store a data chunk, determining whether the data chunk is highly-duplicated among the storage servers, accepting the request when the data chunk is highly-duplicated, and rejecting the request when the data chunk is not highly-duplicated.

Abstract: A backup entity and a method for backing up a disk volume of a production device are provided. The backup entity is configured to: create a first backup image of the disk volume, in a backup repository. Further, the backup entity is configured to obtain a first indication from the production device, wherein the first indication is indicative of a first operation to be performed by the production device on the disk volume. The backup entity is further configured to perform the first operation on the first backup image, to obtain a second backup image in the backup repository. According to the application, a solution to mimic an operation that changes data of a production storage, in a backup system, is provided, which can reduce the amount of data sent from the production storage to the backup system and thus reduce a backup window.

Abstract: A method and a global server for deduplicating multiple storage servers are disclosed. The global server maintains information regarding a set of hash values, each hash value being associated with a data chunk of data stored in the global server and/or the storage servers, receive, from one or more of the storage servers, a request to modify the information with respect to one or more hash values, accumulate and sort metadata related to the one or more requests, modifies the information with respect to the one or more hash values, based on the accumulated metadata when the accumulated metadata reaches a determined size.
