What can be done without a license?

I am trying out Duplicacy and like it so far. What happens if for some reason I don't have a license (say, for example, that you stop developing it and it's no longer possible to purchase a license)? What functionality is restricted? I would like to know that not matter what I can at least restore all files needed.

If you purchase a commercial license then you'll have the access to the latest source code of the command line version. The GUI version is just a wrapper around the CLI version, so with the source code you'll be able to build your own binary and restore all files.

Thanks. To clarify, I was trying to ensure that say, for example, you shut down your company and no longer offered support and I couldn't buy a license. Could I always at least restore files? once committing to this I would like to know there are no risks of loss of functionality in an extraordinary situation.

You can always use the CLI version to restore files from backups without a license. I just updated the license section on our github page to reflect this permission.

It would be very useful if this information was also on the duplicacy.com site --specifically on this page https://www.duplicacy.com/buy.html -- rather than just on GitHub. I wanted this information (is a license required to restore) and I vaguely remembered that I had seen it in the issues and I just spent ~ 20 minutes looking for it. From a developer's perspective the natural place to put this probably is on the GitHub page because that's where the CLI version is being maintained. But from a buyer's perspective, the natural place is on the buy page on the duplicacy.com web site, which is where all of the other information regarding license entitlement is communicated.

Thank you for pointing that out! I've added this statement to https://www.duplicacy.com/buy.html:

In addition, if the purpose is to restore or manage existing backups, the CLI version can be run by anyone on any computer without a valid license.
