What is Duplicati?
Duplicati is a free, open-source backup tool for Windows, macOS and Linux. It backs up files automatically and with encryption to local drives or cloud services. Configuration and management run through a browser-based interface that opens locally. The project is maintained by an active community and is available under a free license.
Core features
- AES-256 encryption: Data is encrypted before upload, so the cloud provider has no access to the plaintext.
- Incremental backups with deduplication: After the first full backup, Duplicati transfers only changed data blocks. This noticeably reduces storage requirements and bandwidth.
- Broad storage support: Google Drive, Dropbox, Amazon S3, FTP, WebDAV and local paths all work as backup targets.
- Scheduled automation: Backups can be planned as daily or weekly jobs without manual intervention.
- Versioning: Duplicati stores multiple versions of a backup, enabling targeted restores to an earlier point in time.
Who is Duplicati for?
Developers and system administrators who want to back up configuration files, databases or server snapshots on a regular basis will work well with Duplicati. Anyone storing sensitive data in a third-party cloud benefits from the fact that encryption happens locally.
For beginners without a technical background, getting started is bumpy. The web interface is clear, but terms like deduplication, retention policies and passphrase management require a willingness to read up on the subject. A misconfigured backup job may go unnoticed until a restore is attempted.
For home users without admin experience, more accessible alternatives exist.
Context & alternatives
Duplicati belongs to the category of self-hosted backup solutions. It competes with tools such as Restic and BorgBackup, which follow similar approaches to encryption and deduplication but work exclusively via the command line. Duplicati stands out through its web interface, which makes it attractive for users who do not want to write scripts.
Those who prefer a purely CLI-based solution and prioritize maximum portability tend to reach for Restic. Anyone who wants to manage multiple backup jobs with different targets through a central interface will be better served by Duplicati.
