Norton Cloud backup saves versions of each selected file every time the backup programme is run. It would be good to have an option to save just a user-selected number of version, for example the last 5 versions and older versions automatically removed from the backup set. This would prevent the set becoming ever larger for files that are regularly updated, such as spreadsheets for example.
A further option that some users might appreciate could be to automatically remove files that no longer exist on the computer from the Backup set. This might be a feature that users would run from time to time to clean up the backup set.
