It does mean, though, that the availability of our (ever growing) photo collection is reliant on Ente's disaster recovery posture. Ente have not given me any reason to doubt them (in fact, their approach to reliability is well documented ), but our photos are utterly irreplaceable and using any hosted offering comes with some risk of disappearance (or of being acquired by a company which goes on to ruin it), often without any prior warning.
