Comment 15 for bug 490188

Florian, a fresh backup should happen at most every month (though I think the old minimum was 2 weeks -- which version are you on?).

Christoph, that would be a neat feature, but Deja Dup relies on Duplicity, which does not have that feature. And it would be impossible/very-difficult to add, since Duplicity does not assume that it can run code on the backend (which allows it to support cloud backends). So it would have to download, repack, and re-upload the chain to support that feature.
