So, say, pick eight cloud providers and do an (8,3) secret-split and
give them the shares.  You can lose any five of them and still be able
to recover your data - and no two or fewer of them can deduce your data
even when cooperating.  Adjust the numbers to suit your levels of
paranoia about loss and about collusion to recover your data without
your approval.
