Backup solution

I need a backup solution software, if i say exactly it will be a webapplication like <[login to view URL]> MOreover i need similar application but if you can add some more features then it would be great. I also want that there should be 3 or more copy save on server, like if user changed there data then a previous version of data save to another folder & then start sync for new data so if there is sudden mistakes done by user on their importan data they can retrive previous data. There should be a rich admin panel required which can control everything. Like Free user backup limit, No. of backups like above stated, user reporting , payment info everything, And site content manager. ? Web Application should run like this way-> user signup -> download application Next step, install and then go through the configuration wizard, which will bring you to a page where you can select the back-up sets you want, such as e-mail and contacts, financial information and photos and images and even your browser [login to view URL] like Favourite, Folders, Images, etc. If you are on the free account the capacity bar at the bottom will tell you when you are over the limit. The next dialogue tests the speed of your connection and then you are told how long the back-up will take to complete. Be warned it will likely be a long time for the first back-up, but will be a lot quicker after that. Finally, make your choice about when you want the back-up to start then click Finish to finish. ? ## Deliverables You have to create Fully Featured CMS baed website + Web application Also support is required for reasonable time period. Data will be save on Linux based server with Cpanel software
