O&O AutoBackup 2 (64-Bit) automatically backs up and synchronizes selected files and folders with an external backup device so that in the event of a data loss it can be accessed again immediately. No further application is needed - Windows Explorer alone will suffice. O&O AutoBackup 2 (64-Bit) can backup files and folders quickly and automatically. For example, if a user wants to backup their photos and videos onto an external USB stick then O&O AutoBackup not only copies the original files but also any future changes made to the files and/or directories. The backup process will start automatically whenever a removable device such as a USB Stick is connected to the computer. The files are copied exactly and put on the target disk so that they can also be accessed without O&O AutoBackup using the normal Windows Explorer.
