| Compare | Duplicati | Duplicacy Forum |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Self-hosters and homelab users | Technical homelab users |
| Who it's not for | Non-technical users wanting set-and-forget backup | Non-technical users wanting set-and-forget backup |
| Privacy | Encryption design is solid (AES-256, zero-trust), but 2026 advisories mean you must run the latest patched version.⁶ | No known public vulnerabilities found in the sources reviewed. |
| Support quality | Community forum only; no vendor support on free tier | Active forum, but maintenance doubts persist |
| Public sentiment | Reviews are split: many call it powerful and unfairly criticized, while others report reliability problems severe enough to switch away.⁴ | Users value the dedup engine and community help but complain about cloud API costs, fiddly setup, and maintenance uncertainty. |
| Biggest gotcha | v2.3.0.1 has a published CERT alert (VU#847406) . run only the latest release⁶ | Chunked backups multiply cloud API operations; one user's bill hit $122 in a month |
