摘要： Range information associated with one or more objects is received from a storage system. One or more missing ranges and/or one or more mismatched ranges associated with the one or more objects is determined based on the received range information. A plurality of data chunk identifiers associated with a plurality of variable-length data chunks included in the one or more determined ranges associated with the one or more objects is provided to the storage system. A response that is used to identify among the plurality of variable-length data chunks, one or more variable-length data chunks not already stored in a storage associated with the storage system is received from the storage system. Content of the identified one or more variable-length data chunks is provided to the storage system.

摘要： A backup of one or more objects is determined to be performed. Based on one or more conditions, a corresponding deduplication option among a plurality of deduplication options to utilize when backing up the one or more objects is selected. The one or more conditions at least include a condition based on a detected data change pattern. The plurality of deduplication options include a deduplication option associated with utilizing at least in part a plurality of variable-length data chunks for one or more mismatched ranges and/or one or more missing ranges associated with one of the one or more objects associated with the source system. A request to perform the backup of the one or more objects according to the corresponding selected deduplication option is provided to the source system. Backup data associated with the one or more objects is received and stored.
