Abstract
One implementation of a method for providing backup storage services for encrypted data includes receiving signatures of convergently encrypted portions of data from client computers, determining whether the encrypted portions are already present on a backup storage, and obtaining only the needed portions. Users unassociated with a particular user account are denied access to information backed up in that account. The backup storage also stores password protected key files holding signatures of the unencrypted portions of data. One implementation of a system includes a memory, a single-instance storage circuit, a user account management circuit, and a signature index. The memory holds a user-account database and backup copies of convergently encrypted portions of data. The single-instance storage circuit uses the signature index to prevent duplicative backup copies. The user account management circuit responds to download requests after authenticating the user information associated with the requested data.
