FBackup is a free, lightweight automated backup program that can effectively protect your important files and folders from being lost.
It protects that data by automating backup tasks, password protecting, and compressing it to save storage space. Using FBackup, you can easily backup to any local or network drive or external drives (USB drives).
FBackup can backup open/locked files, and it can perform full and mirror backups (backup type that does not compress the files) and has ZIP64 support (can create backups over 2 GB) and creates standard zip files, meaning that you can access it with any zip compatible utility. FBackup also allows you to password-protect your backup. FBackup tests the backup files automatically to ensure the backup is safe and correctly executed (uses CRC32).
