ABSTRACT:
The present invention is capable of determining the rights to a file based on providing a descriptor. The descriptor can be calculated using an algorithm, which may be cryptographic and/or non-cryptographic. The descriptor may further be based on the file contents, metadata of the file, other file data, or any combination thereof to uniquely identify the file in a shared file repository. Since the descriptor is generated based on file data it will be the same regardless of which user generates it. Accordingly, only one copy of the file needs to be maintained in the shared file repository, thereby reducing the amount of network bandwidth required to assure the file is backed up and further reducing the amount of storage required to backup the files. This results in a vastly more efficient method of backup in terms of processing time, network bandwidth, and storage requirements.
