摘要： Maintaining a synchronous replication relationship between two or more storage systems, including: receiving, by at least one of a plurality of storage systems across which a dataset will be synchronously replicated, timing information for at least one of the plurality of storage systems; and establishing, based on the timing information, a synchronous replication lease describing a period of time during which the synchronous replication relationship is valid, wherein a request to modify the dataset may only be acknowledged after a copy of the dataset has been modified on each of the storage systems.

摘要： A method of data loss prevention during transitions from a replication source, the method including: initiating a transition from using a first data repository as a source for data replication to using a second data repository as the source for data replication; prior to completing the transition and responsive to determining that one or more storage operations directed to the first data repository have not been replicated to the second data repository, delaying transition of the second data repository as the source for data replication; and responsive to completing the transition, promoting the second data repository as the source for data replication such that all storage operations received after completing the transition are directed to the second data repository.

摘要： A method of managing host mappings for replication endpoints, the method including: identifying a target storage system replicating a source dataset of a source storage system, wherein a first host is mapped to the source dataset on the source storage system; providing, to the target storage system and in dependence upon a mapping of the first host to the source dataset, configuration information for connecting to a second host; and implementing, in response to a triggering event, a mapping of the second host to a replica dataset on the target storage system.

摘要： Transitioning between replication sources for data replication operations, including: delaying a transition from using a first data repository as a source for data replication to using a second data repository as the source for data replication after detecting that one or more storage operations directed to the first data repository have not been replicated to the second data repository; and promoting the second data repository as the source for data replication such that storage operations received after completing the transition are directed to the second data repository.
