Acrosync has launched Duplicacy 1.0, a cross-platform cloud backup tool that’s compatible with Mac OS X Yosemite and El Capitan.

The utility uses a lock-free deduplication method, so it can backup multiple clients to most popular cloud-based storage services without the need for any file locks. The app also offers the ability to perform backups to local hard drives, SFTP servers, and NAS boxes. Duplicity’s graphical user interface features one-page backup configuration.

Duplicacy 1.0 is free for personal use, and is available worldwide exclusively through the Duplicacy website (http://duplicacy.com). Commercial users pay $2.00 per month per computer. A Windows version is also available for download from the Duplicity website.
