Since Revest backs up your files incrementally, it will create a new version of your files once they get modified, and you can select to restore an older version of your wanted file.
Revest Business users can control how many versions of the files they want to keep in their backup. For more information, please click here.
Revest Suite Home users cannot control how many old versions they want to keep in their backup. The versions of the files are purged automatically as Revest Suite Home will keep only the last 10 versions of each file.
