Set up backups for bananas-archive
The contents and metadata (e.g. underlying reprepro database and so on) of the archive can be re-created by simply rebuilding the packages. Still, we should have backups of at least the debs to avoid wasting resources (and time/energy) on rebuilding. Metadata takes up a tiny fraction of space, so we can have backups of the whole archive (excluding installer images to save space and/or backup time). rsync for DDs can help us here. It offers 500GB free space for owners of @debian.org email addresses.
