1. A backup and restore system comprising:

  • a server-side portion that receives backup and restore requests and processes the backup and restore requests by returning encrypted data blocks in response to a restore request, and storing encrypted data blocks and file signatures in response to a backup request; and

    a client-side portion that provides a user-interface that allows files to designated for continuous backup, includes a service process that detects changes to files designated for continuous backup, computes file signatures, computes, by file-signature comparison, blocks needed to be stored for backup and restore operations, and issues requests for backup and restore operations, and includes a transport service process for exchanging requests and data with the server-side portion.
