Rapidusb Backup software makes backups and updates files very quickly from the hard disk to a USB key. Its uniqueness is that it selects only files and folders that have been modified, created or deleted, it does not copy unnecessarily files that have not been changed which makes a gain in time on a traditional backup. At the end of the backup folder of the USB drive is strictly the same as to the hard disk. Backups can be either manual or automatic: One day of the week, or once a day, by the hour, half hour, quarter hour, every 10 minutes or at windows startup eventually. Easy to use, just a few clicks to automate backups and one click for manual backup.
