Abstract:
A method is used for managing cache backup and restore for continuous data replication and protection. I/O operations are quiesced at a cache module. A first snapshot of a storage object and a second snapshot of an SSD cache object are taken. The I/O operations at the cache module are unquiesced. A single backup image comprising the first snapshot and the second snapshot is created. The single backup image is sent to a first data protection appliance (DPA) and recorded in a journal.
