Many thanks. I should have studied the documentation closer.
However, that leaves the question hanging as to why, without a subscription, the data is inaccessible to the user after three hours when it could clearly still be made available locally ?
Pray tell, one would assume the scenario where a local recording was unable to be upload for e.g. a fifty hour period, only for it to be immediately deleted upon upload ?
Looking at the unpaid service from a consumer's point of view they would surely expect to be able to retrieve the local content that was recoded on their private premises, with a product purchased with their own funds. However, once that data is in the hands of a third party, on their servers, it then at the mercy of the subscription package terms and conditions.
Surely Google is being a little stingy, here ?
