        "overview": "Duplicacy backs up files to many cloud storage services with client-side encryption and deduplication. The site describes a method it calls Lock-Free Deduplication, which it says makes deleting old backups possible without a centralized chunk database.\n\nBesides cloud storage, Duplicacy supports local disks and your own SFTP servers, including Mac or Linux computers and NAS boxes, and it has a newly designed web-based interface. The command-line version is free for individual users, while commercial licences are priced per machine per year, so check the current price on the buy page before using it at work.",
