You don't need to use a separate provider to address the problem here, where using a separate provider may not address the problem at all:

You could backup to a different account, possibly in a different region, with the same provider, as long as the other account has a different payment method. Using one provider would in most cases reduce the amount of effort to get back up and running.

The key piece would be how DNS is structured and hosted/billed.
