A mechanism is provided for replicating non-supported data types using an existing replication format supported by an existing replication system. Responsive to detecting an application writing data to a local storage that is to be replicated to the secondary site, the input/output (I/O) operation being performed by the application is intercepted. Data of the I/O operation in a non-supported format is converted to a format supported by the existing replication system. A replication log record is generated for the data in the format supported by the existing replication system. The data described by the replication log record for the data is then stored in a storage device at the secondary site.
