Backup* means that the data is backed up to another independent storage system, such as to another server room or tape storage. This protects data from the destruction of the entire storage system in a catastrophe. Usually the time window of automated backup is rolling and limited, meaning that you can restore data as it was 2 months ago, but not half a year ago.
Version control** means that the same storage system preserves previous versions of the files, in order to protect against accidental deletion. A deleted or damaged file can be recovered from its previous versions during a limited time depending on the system. The data is not protected in case of a collapse of the storage environment itself.
Capacity*** is usable net capacity that the user can allocate. On many cases, the capacity may vary and can something up to the maximum capacity.
