Abstract
In one example, a method is provided for backing up client data at a datacenter. Initially, an incremental backup is received from a client and stored at the datacenter. Next, a table of contents for the incremental backup is created, and differences identified between the incremental backup and a dataset previously stored at the datacenter. The offsets imposed by any new or modified blocks present in the incremental backup can then be identified and recorded, and used to identify respective data ranges in the incremental backup for any new and modified blocks, which data ranges can then be recorded. Next, a reference block can be created for each block of the previously stored dataset that was not modified in the incremental backup. The reference block can then be stored at the datacenter in association with the incremental backup.
