What it really is

Duplicacy — cross-platform cloud backup tool with lock-free deduplication and support for 20+ storage backends.

Our take

Duplicacy is a developer-friendly backup utility offering highly efficient cross-cloud backup via chunk-level deduplication. The DB lists 'Enterprise pricing' as the pricing field — misleading, as Duplicacy is a personal and commercial tool with very affordable per-computer annual licenses, not an enterprise product. The CLI version is completely free for personal use. The freemium price_tier in the DB is appropriate.

Why we rate it

Best-in-class deduplication efficiency at a price point that undercuts every managed backup SaaS; transparent open licensing and perpetual restore rights are confidence-builders.

The catch

Requires technical comfort to configure; no bundled cloud storage — you must provision your own (S3, Backblaze B2, Azure Blob, GCS, etc.).

Best for
IT admins managing multi-cloud backup across diverse storage backends
Developers and power users wanting deduplication to minimize cloud storage costs
Small businesses running their own storage infrastructure
Not good for
Non-technical users expecting a managed, click-and-go backup service
Teams wanting bundled cloud storage with zero infrastructure management
Organizations needing centralized backup dashboards with role-based reporting
Friction report
Time to value
Moderate: CLI configuration and cloud storage credentials required before the first backup run.
Scale breakpoint
Per-computer commercial licensing adds up at 20+ machines; evaluate enterprise-tier alternatives at that scale.
Walled garden
Low: open backup format; restore and check commands are free regardless of license status.
