A company replaced on-premises tape hardware with an AWS Storage Gateway Tape Gateway. Backup jobs occasionally fail with a “Not Enough Space” error when writing to AWS virtual tapes. The organization wants to avoid these failures and ensure there are always sufficient virtual tapes available in AWS with minimal operational overhead. What should the SysOps administrator do?

The correct answer is to enable the Tape Gateway auto-create tapes feature. This feature directly addresses the problem by automatically provisioning new virtual tapes when the number of available tapes falls below a specified minimum, preventing "Not Enough Space" errors with minimal operational overhead. The other options are less efficient or effective. Creating a Lambda function to check free space and provision tapes (option 1) requires custom scripting and management, which is more complex than the built-in auto-create feature. Installing the CloudWatch agent and creating metric filters (option 2) is reactive, only addressing the issue after an error occurs, rather than proactively preventing it. Deploying a second Tape Gateway (option 3) is an unnecessary and costly over-provisioning of resources and doesn't directly solve the problem of running out of tapes on the primary gateway.
