Embodiments are described for storing array snapshots of a block-based system in networked storage, such as an NAS or SAN device. A system and process determines a size of the block device and splits it into a number of slices based on the size of the block device, with each slice comprising slice data. The slice data is written to protection storage either directly or through temporary buffer memory. The slice number and memory location for the slice data is stored in a key/value map, where the key comprises the slice number, and the value comprises the location. Backup agents are deployed to back up the slice data for each slice of the block device to the networked storage, and the slice data is stored as array snapshots in the network storage.
