3-2-1 rule for backups: 3 copies, 2 different physical mediums on the same site (if you're on AWS, they handle that for you), 1 off-site (NOT AWS). This is the minimum for a data backup to count as "backup", not the maximum.

Backup your AWS data, backup your Google data (Gmail, Drive, and GCP), backup your on-prem data (to the cloud, or a different building), etc.
