Abstract
Described embodiments provide systems and processes for performing a data replication process in a storage system. A current asynchronous replication cycle is initiated at a time-based interval based upon a replication policy of the storage system to replicate data from at least one source device to at least one target device. For the current asynchronous replication cycle, it is determined whether data stored on portions of the source device has changed from a previous asynchronous replication cycle. A new replica of the source device is generated if data stored on the source device has changed from the previous asynchronous replication cycle. The new replica is transferred to the target device. The current asynchronous replication cycle is completed and the replication policy of the storage system is satisfied without generating the new replica if data stored on the source device has not changed from the previous asynchronous replication cycle.
