I am a bit concerned
Looking at the comments here, that people seem to be under the impression that hosting providers systematically keep back ups of customer data.
That is not the case, chaps. For a start it'd be uneconomical and uncompetitive; you'd be paying for the back ups whether you actually needed them or not¹. Then there is that whole box of worms with GDPR and similar laws, where if you do not control your back ups you might end up in a position where you cannot actually comply with legal or industry regulations concerning data rights, security, etc.
¹ For instance, I have used shared hosting to process one terabyte of data twice a day. The data is obsolete after about twelve hours and expensive enough as it is, without having to pay for it twice.
