WRITE-BACK CACHE TRANSACTION REPLICATION TO OBJECT-BASED STORAGE

A system and method for replicating object-based operations generated based on file system commands. In one aspect, a object storage backed file system cache includes a replication engine that selects, from an intent log, records for multiple transaction groups. Each of the records may associate an object-based operation with a transaction group identifier that is associated with a file system command from which the object-based operation was generated. The replication engine identifies transaction groups that each include at least one object-based operation associated with a same transaction group identifier and reads object data associated with at least one of the object-based operations. The replication engine determines operation dependencies among the transaction groups based on the object data and sequences the transaction groups for replication based on the determined operation dependencies.
