Duplicacy: lock-free deduplication backup tool with a new web interface

[prMac.com] Clifton Park, New York – Acrosync LLC today is pleased to announce the release and immediate availability of Duplicacy Web Edition 1.2.1, a web interface for the popular open-source backup tool Duplicacy. Duplicacy is the most advanced backup tool, offering 3 unparalleled features that can’t be found in any other backup tools.

First, Duplicacy takes a unique database-less approach where every chunk is saved independently using its hash as the file name to facilitate quick lookups. The removal of a centralized chunk database means Duplicacy is more robust and less error-prone, and this simple yet elegant design makes implementing advanced features much easier.

In addition, Duplicacy is the only deduplication backup tool that allows multiple computers to back up to the same cloud storage, taking advantage of cross-computer deduplication whenever possible, without direct communication between them. In a large-scale deployment, this feature is essential for minimizing the cost of network bandwidth and storage, as well as maximizing backup speeds.

But the most distinguishing feature of Duplicacy is a novel technology 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. Lock-Free Deduplication not only enables the data-baseless approach and cross-computer deduplication, but also brings other important benefits, such as allowing a prune job to run in parallel with multiple backup jobs.

With the addition of the newly designed web-based GUI, Duplicacy users can now effortlessly set up backup, copy, check, and prune jobs that will reliably protect important data while making the most efficient use of local or cloud storage space. The intuitive dashboard presents several statistical charts providing insights into the overall health of backups and storages.
