DirSync Pro is focused on real-time file synchronization and offers features like versioning and bandwidth throttling, making it suitable for continuous backup needs. Duplicati, on the other hand, is geared towards cloud backups with strong encryption and incremental backup capabilities, ideal for users needing secure and efficient cloud storage solutions.
