Within CDW’s AWS practice, we maintain a number of AWS accounts for managing our day-to-day business activities. One of the accounts is the “Sandbox Training” account that provides an environment for our CDW coworkers to learn and experiment with a multitude AWS services.
Periodically, we go to the account and try to understand the cost and resource usage pattern within the account. Recently I found out that there were many snapshots created by AWS Backups in our training account. Most likely, the vault was created as a part of the training and learning exercise. The AWS Backup policy was created to back up a few EBS volumes every night. Due to an oversight, the user forgot to delete the backup policy after the experimentation was over.
