Patent attributes
Described are data replication techniques that may include receiving, on a host, a write operation that writes first data to a target location on a first logical device having storage provisioned on a first data storage system; determining, on the host and in accordance with one or more criteria, whether the first data is to be replicated on a second logical device on a second data storage system; and issuing the write operation from the host to the first data storage system, wherein the write operation denotes whether to disable replication of the first data to the second logical device on the second data storage system. Such techniques may include partitioning a single write operation into multiple write operations and setting an indicator in each of the multiple writes denoting whether remote replication of the write operation is enabled or disabled.
