I'm sorry that you are not satisfied with the security measures for the Norton 360 v2 Backup. The product is customer oriented by creating a secure method of storing data for users without the means of other storage methods (image-based, incremental storage, etc).

From what I've read, it seems that your concern is rather with the ease-of-use in accessing the files of a backup. If you are looking for a product that will provide this granular interaction with the data, I would recommend Norton Ghost 14. This product will let you 'drill down' into backup images to access specific files, and allow you to restore files from a specific time in backup history. Thanks!
