Summary

Duplicacy is a cross-platform file backup tool for Windows, macOS, and Linux. It can send files to cloud storage, local disks, and SFTP servers, including computers and NAS boxes. Client-side encryption is optional: users set a password when initializing storage to encrypt it, while an empty password leaves it unencrypted. Duplicacy uses lock-free deduplication and a two-step fossil collection process to remove chunks that are no longer referenced without a centralized chunk database. The Web Edition supports backup, restore, check, copy, and prune operations, plus scheduling and email notifications; its dashboard displays storage and backup status. The CLI can be run manually or from scripts, and its source code is available on GitHub. CLI personal backups on a home computer do not require a license, and CLI restore, check, copy, and prune operations also require no license. The Web Edition automatically downloads a fully functional 30-day trial license when used for backups without a license. Paid license prices and terms vary by use and number of computers.

Who it is for

Duplicacy suits people who need file backups to cloud or local destinations and want a choice between its Web Edition and command-line tools. The free CLI personal-use option is for file backups on a home computer.

What is good

  • Supports cloud storage, local disks, and SFTP
  • Client-side encryption can be enabled with a password
  • Web Edition supports scheduling and email notifications
  • CLI personal backups on a home computer need no license

What to know first

  • Leaving the storage password empty means it is unencrypted
  • GUI licenses are limited to one computer
  • Personal GUI licenses cover home use, not work files

Verdict

Duplicacy offers several backup destinations, optional encryption, and both GUI and CLI workflows. Review the license terms for the intended use and computer count, and set a password if encryption is needed.
