Abstract
A method for asynchronous replication, the method includes initiating a current replication cycle of multiple files system entities (FSEs) that include primary FESs originated from a primary storage system (PSS) and external FSEs that originated from one or more external storage systems (ESSs), each external storage system differs from the primary storage system and differs from a secondary storage system. The initiating is followed by sending primary content and external content from the primary storage system to the secondary storage system. The primary content is indicative of differences in the primary FSEs between a previous replication cycle point in time (PIT) and a current replication cycle PIT. For each external FSE, an external content is indicative of differences in the external FSEs between (a) a last external FSE snapshot that preceded the previous replication cycle PIT and was generate by an external FSE snapshot process, and (b) a last external FSE snapshot that preceded the current replication cycle PIT and was generate by the external FSE snapshot process. The external FSE snapshot process and a process for generating the current replication cycle are not mutually synchronized.
