Auto USB Backup is a lightweight and easy to use application developed to offer you a reliable method of backing up your most important files and documents to a USB storage device, performing the operation automatically, without interrupting you with prompts or requests.

The utility features a colorful, table-style appearance, initially displaying a start screen that will provide you with some instructions on how to best benefit from what Auto USB Backup has to offer.

The main window lists the common data sources, allowing you to add new ones or check the boxes for the folders that you wish to work with on a regular basis.

Auto USB Backup will automatically target your libraries, specifically the documents, music, pictures and desktop. However, you can easily choose other directories from your system to be backed up, by checking a ‘Not Set’ box, then clicking on the ‘Browse’ option to select the preferred directory.

Using the ‘Calculate Folder Sizes’ function, you can estimate how much space your files will occupy, so you can connect a USB drive with sufficient capacity. Before saving the changes, you can type a preferred name in the last field of Auto USB Backup's main window and press on the ‘Find USB Device’ button to identify the proper drive.

Finally, you can ‘Save Changes’, and the program will take care of the rest, remembering the current configuration for future operations and applying it accordingly. If you wish to disable it, you can just click on the ‘Automatic Backup is ON / OFF’ button or use the ‘Full Auto Re-setup’ feature, if you wish to alter the settings.

To summarize, Auto USB Backup is a useful and effective piece of software aimed to help you prevent the risk of completely losing your most important documents, in case of a system failure, by performing automatic backups of selected folders, whenever you connect a portable memory device to the computer.
