Duplicati is an open-source backup tool that encrypts your data client-side before uploading it to cloud storage services like AWS S3, Google Drive, or OneDrive, ensuring your backup provider cannot access your files. Developers use it to automate encrypted backups of databases, source code, and other critical data without trusting the storage provider with unencrypted information. It supports multiple storage backends including SFTP and WebDAV, and provides scheduling and retention policies for managing backup versions.
