Abstract
Described are techniques for mirroring data that may include issuing, by an application on a host, a write operation that writes first data to a primary storage entity having data stored in accordance with a first format and first structure; intercepting, on the host, the write operation; and performing, on the host, first processing to process the write operation. The first processing may include: sending the write operation to a data storage system including the primary storage entity; determining whether the primary storage entity is mirrored as a second storage entity having data stored in a second format and second structure different from the first format and first structure; and responsive to determining the primary storage entity is mirrored as the second storage entity, issuing one or more second write operations to mirror the first data on the second storage entity in accordance with the second format and second structure.
