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

Why teams pick Duplicati over alternatives

  • Strong encryption — AES-256 with passphrase, encrypted before upload
  • Deduplication — block-level dedup reduces storage cost
  • Incremental forever — only changed blocks uploaded
  • GPL-2.0 — fully open
  • Broad cloud support — S3, B2, GDrive, OneDrive, WebDAV, FTP, SFTP, etc.
  • Web UI — manage backups visually instead of CLI scripting

Integrations

  • Cloud storage — S3, Backblaze B2, Google Drive, OneDrive, Dropbox, Azure
  • Self-host targets — SFTP, FTP, WebDAV, SMB / CIFS
  • Local targets — local filesystem, USB, NAS
  • Notification — email, Discord, Slack on backup success / failure
  • Schedule — cron-like for daily / weekly / custom schedules
  • Retention policies — keep N versions, time-based, smart retention
  • Restore granularity — restore single file, folder, point-in-time

Notable users & community

  • 12k+ GitHub stars
  • Active community in r/selfhosted and r/DataHoarder
  • Backed by Duplicati Inc.
  • Long-running OSS project (>10 years)

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
