Versioning
This is a file system which allows a computer file to exist in several versions at the same time. Most common versioning file systems keep a number of old copies of the file. This allows users to recover or view earlier versions of documents that have been since modified or partially deleted.

Archiving
Data archiving is the process of moving data that is no longer actively used to a separate storage device for long-term retention. Archive data consists of older data that is still important to the organization and may be needed for future reference, as well as data that must be retained for regulatory compliance.

Sovereignty
Data sovereignty is the concept that information which has been converted and stored in binary digital form is subject to the laws of the country in which it is located.
