Duplicati
App in the BluixApps catalog
What it is
Duplicati is a backup client with strong encryption, deduplication, incremental backups, and broad cloud storage support — S3, Backblaze B2, Google Drive, OneDrive, FTP, WebDAV, SFTP. Web UI for managing backup jobs, scheduling, restore. Open-source, cross-platform, with a focus on encrypted off-site backup.
For self-hosters who refuse to trust cloud backup providers with unencrypted data.
What it's for
- Encrypted cloud backup — AES-256 encryption before upload
- Server backup — backup VPS data to cheap object storage
- Personal NAS backup — household data archival
- 3-2-1 backup strategy — local + cloud + off-site backup
- Cross-cloud backup — backup from one cloud to another for redundancy
Who it's for
- Self-hosters wanting encrypted, automated VPS backup
- Photographers archiving photo libraries to cheap S3
- Small businesses backing up critical data to off-site cloud
- Privacy-conscious users rejecting cloud backup with vendor-side encryption
- Sysadmins building automated backup pipelines for client servers

Tips & operations
- Test restores regularly — backups you can't restore are worthless; verify quarterly
- Strong passphrase — losing this = losing your backups; store in password manager
- Encrypt at the source — Duplicati encrypts before upload; never enable cloud-side encryption (key custody risk)
- Monitor backup status — email / webhook notifications essential; silent failures common
- Retention policy — define retention upfront; cleanup old versions to control cost
- Mind first-backup time — initial full backup of large datasets takes hours / days
