  • delta differencing

    Delta differencing is an incremental approach to backup that only backs up blocks that have changed after the first full backup. The differences are recorded in files called deltas.

  • network-attached storage (NAS)

    Network-attached storage (NAS) is a dedicated hard disk storage device that provides file-based data storage services to other devices on the network.
