This addresses the "how to encrypt the backups" problem, but I don't
see how it addresses the "how to backup the files in the first place"
one. May you please elaborate what you have in mind?

+ it's hard to correctly guess what size the container file should be.

Point taken.

AFAIK, obnam only supports encrypting to a GnuPG key, so this would
require another layer of encryption (such as a LUKS container file, or
something else) if we want to support encrypting with a passphrase
(and I think we should).

Sounds like it's probably worth a Research ticket + a blueprint.
Looking at how others have solved this problem would be great.
