Duplicati

A free backup client that stores encrypted, incremental, compressed backups to cloud storage and remote servers. Supports 30+ storage backends including Amazon S3, Backblaze B2, Google Drive, OneDrive, Dropbox, SSH/SFTP, and WebDAV.

What You Can Do After Deployment

1. Visit your domain — the Duplicati web UI opens on first access; no login is required by default (you can set a password in Settings)
2. Create a backup job — click "Add backup", choose encryption passphrase, select files/folders from the /source volume, pick a destination (cloud or /backups volume), and set a schedule
3. Restore files — browse existing backups and restore individual files or entire folders to any point in time
4. Monitor status — the dashboard shows backup history, next scheduled run, and any warnings

Key Features

• AES-256 encryption — backups are encrypted before leaving the server
• Incremental and compressed — only changed data is uploaded after the initial backup
• 30+ backends — S3, B2, Google Drive, OneDrive, Dropbox, FTP, SSH/SFTP, WebDAV, Azure Blob, and more
• Built-in scheduler — set daily/weekly/custom schedules per backup job
• Deduplication — identical data blocks are stored only once across all backups
• Web-based UI — manage everything from a browser
