Should I Use Duplicacy Forum?

forum.duplicacy.com·Analyzed 3 days ago··Based on 13 sources

A place for Duplicacy users and developers

Verdict

Depends

This URL is Duplicacy's community forum, not a product page — the product behind it is Duplicacy backup software.

Confidence: Medium

Buy if you're technical and want deduplicated cloud backups; skip if you want simple, set-and-forget backup.

This is Duplicacy's user forum, not a product page. Good dedup backup for techies; too fiddly for casuals.
