How does retention work?

Thanks for that. But that is a different help text. Above, we were looking at Duplicati.CommandLine.exe help delete and while I had no doubt that the information could be found somewhere, my point was precisely: can we not make life easier for people and give them a hint right where they need it, i.e. when looking at help delete?

Seeing that I need to query help date in order to learn the format, I would even argue more strongly for that because delete help speaks about <time> (not <date>) so that it’s not very intuitive, even when you know how to use Duplicati.CommandLine.exe help.

Yes, but that is only in canary at the moment, right?
