Backup

Duplicati

A backup client with a web UI that stores encrypted, incremental, compressed backups on cloud storage and remote servers: S3, Backblaze B2, OneDrive, Google Drive, WebDAV, SFTP, FTP and more. The open-source core is MIT-licensed C# on .NET (a few connectors under a proprietary/ directory need a paid subscription); it runs as a single container with its own SQLite databases in /data and backs up whatever host paths you mount into it.
