Duplicacy Web Edition is a web interface to the popular open-source backup tool. Unlike other backup tools, Duplicacy is built on top of a novel idea called Lock-Free Deduplication, which works by relying on the basic file system API to manage deduplicated chunks without using any locks. A two-step fossil collection algorithm is devised to solve the fundamental problem of deleting unreferenced chunks under the lock-free condition, making the deletion of old backups possible without using a centralized chunk database.
Thanks to Lock-Free Deduplication, Duplicacy work smoothly with most cloud storage services without compromising any essential features required of a state-of-the-art backup tool. In addition, Duplicacy also supports local disks and your own SFTP servers such as Mac or Linux computers, or NAS boxes.
With the newly designed web-based GUI you can effortlessly set up backup, copy, check, and prune jobs that will reliably protect your data while making the most efficient use of your storage space. The intuitive dashboard includes several statistical charts that help you monitor the overall health of your backups and storages at a mere glance.
