I spoke out loudly at a previous employer how it's really dumb to have our database and it's backups under a single AWS account. A single AWS account compromise, account issue (e.g. AWS shuts down account), or a disgruntled employee could result in the business being destroyed.

They took some half-hearted efforts to back up the data, but it was far from ideal.

Back up your data, and do it in different places so a failure in one won't affect any other copy of the data.
