Abstract
Embodiments for providing memory for continuous data protection in a data storage system by storing a first key-value map as a data structure wherein the key is an address of a volume and the value comprises timestamp and hash value pairs for each time the address had data written thereto, and corresponding hash values of the written data, and storing a second key-value map as a data structure wherein the key comprises the hash value and the value comprises the written data. The first key-value map and second key-value map are implemented as a driver component in a server computer of the data storage system. The driver exposes a block device protocol on the server computer and leverages the key-value data structures for use with a deduplication storage system.
