Alternatives to Duplicati
Open source encrypted backup to any cloud
Duplicati ranks #1 of 12 in Backup software, with an Alt Score of 100. It is licensed under MIT, open source with paid hosting from $2/machine/month and available on Windows, macOS and Linux. 10 of 10 checklist rows are verified against a public source.
Individuals and technical users (e.g., self-hosters, sysadmins) who want to back up personal or server files to cloud or remote storage without paying for a commercial backup service.
Duplicati produces encrypted, incremental, deduplicated backups, encrypting data locally (AES-256) before it leaves your machine. It supports a wide range of storage backends, including S3, Azure Blob, Google Drive, Dropbox, OneDrive, SFTP, WebDAV, and local/external drives. A local web UI lets you configure backup jobs, schedules, and retention policies (keep N versions or backups for a set duration).
You install the client, then use its web interface to define a backup job: pick source folders, a destination/storage backend, an encryption passphrase, and a schedule. Duplicati then runs backups in the background, uploading only changed data blocks, and you restore files by browsing and selecting from the stored versions through the same web UI.
