Abstract
System and method for managing snapshots of storage objects in a storage system use a consolidation operation to reduce read amplification for stored snapshots of a storage object that are stored in log segments in the storage system according to a log-structured file system as storage service objects. The consolidation operation involves identifying target log segments among the log segments that include live blocks that are associated with the latest snapshot of the storage object and determining the number of the live blocks included in each of the target log segments. Based on the number of the live blocks in each of the target log segments, candidate consolidation log segments are determined from the target log segments. The live blocks in the candidate consolidation log segments are then consolidated to new log segments, which are uploaded to the storage system as new storage service objects.
