I suppose it greatly depends on which persistence technology we're talking about and the reasons for wanting backups. When using Cloud SQL, some standard MySQL tools should work. For GCS, code might have to be written to efficiently extract and load files, but with a low level storage solution like that and with multiregional options, disaster recovery is not too problematic. So the only reason to have good extraction and loading capabilities for GCS are for moving your project to or from other cloud providers and for ETL integrations.
Datastore gives a lot of flexibility as far as data management is concerned. It can be done by the application in the most suitable way. One intriguing feature of Datastore is that indexes can be chosen by each entity stored. This can be a boon to a data management strategy that involves storing multiple versions or deltas of entities and uses a batch process to consolidate, replicate, or back up new entities. Such a batch process can use a special index on a field that flags fresh entities that are up for processing and then remove them from this index upon completion.
