Backup (and resrore) the whole network

As far as I understand, Snapshot only allows to backup individual sites, not the whole network at once. Please correct me if I got this wrong.

Do you (as of when?) plan to change that, so that I can backup (and restore) the whole network & database in one step?

In case you are not going to include this: Is there a solution you can recommend?

Thanks for your support on this issue
