Abstract
Before backing up a user file to backup storage, a trust deduplication module is configured to ask a limited set of other trust deduplication modules to check if the user file has already been backed up. If the user file is already backed up, a backup receipt that corresponds to the user file (which was provided during backup of the user file) is communicated to the requesting trust deduplication module. The backup receipt provides the requesting trust deduplication module with access to the already-backed up user file in backup storage, and the requesting trust deduplication module need not back up the user file. Thus, a single copy of the user file can be stored in backup storage among several trusted users who own an instance of the user file. A user file can be restored from backup storage, using a backup receipt that corresponds to the user file.
