Abstract
Methods and systems for backing up and restoring different point in time versions of a virtual machine, an application, a database, or an electronic file using independently managed snapshot chains are described. In some cases, different point in time versions of a virtual machine may be captured and stored using one or more snapshot chains. Each snapshot chain may correspond with a base image (e.g., a full image snapshot) and one or more incremental files (e.g., two forward incremental files) that derive from the base image. A snapshot chain may be split into a plurality of shards or sub-chains such that the width of each shard or the maximum data size of the files in each shard is less than a threshold data size (e.g., is less than 1 TB). Data operations (e.g., consolidation and reverse operations) may be performed on the individual shards or sub-chains in parallel.
