+encrypt the result.  Feed another @file{.tar} file, and it will also
+re-use any data found in any previous backups.  This way only new
+changes are stored, and as long as the files are not very different,
+the amount of storage required is very low.  Any of the backup files
+stored previously can be read back in full at any time.  The program
+is format-agnostic, so you can feed virtually any files to it.")

Hi Nicolas,

> The following patch adds zbackup.

This broke “guix pull” momentarily because your patch didn’t import two
modules: (guix build-system cmake) and (gnu packages protobuf).

It’s now fixed.

Oh! Apparently, I forgot to "./pre-inst-env guix build" on this one.
Sorry about that.
