Subject: [PATCH] fix cloud backup

by making the BackupAgent-extending class public

also, dereive directly from BackupAgent, because only the profile
configuration is stored, not the whole database

as a side action, drop the backup descriptor and its mention in the
manifests, because it is not used in the key-value backup MoLe uses
