Topic 1 Question 370
A company has a large on-premises tape backup solution. The company has started to use AWS Storage Gateway. The company created a Tape Gateway to replace the existing on-premises hardware. The company's backup engineer noticed that some of the backup jobs that were supposed to write to AWS failed to run because of a "Not Enough Space" error.
The company does not want these failures to happen again. The company also wants to consistently have enough tape available on AWS.
What is the MOST operationally efficient way for a SysOps administrator to meet these requirements?
Create an AWS Lambda function that runs on an hourly basis and checks how many tapes have available space. If the available tapes are below a certain threshold, provision more.
Install the Amazon CloudWatch agent on the on-premises system. Push the log files to a CloudWatch log group. Create an AWS Lambda function that creates more tapes when the "Not Enough Space" error appears. Create a metric filter and a metric alarm that launches the Lambda function.
Create an additional Tape Gateway with its own set of tapes. Configure Amazon Simple Notification Service (Amazon SNS) to send a notification to the backup engineer if the tapes that are associated with the primary Tape Gateway do not have available space.
Configure tape auto-create on the Tape Gateway. In the auto-create settings, configure a minimum number of tapes, an appropriate barcode prefix, and a tape pool.

The Tape Gateway automatically creates new virtual tapes to maintain the minimum number of available tapes that you configure. It then makes these new tapes available for import by the backup application so that your backup jobs can run without interruption. Automatic tape creation removes the need for custom scripting in addition to the manual process for creating new virtual tapes.

Auto-Create function is more efficient for this.
👍 2jas26says2023/07/21 Options A, B, and C may address the issue, but they introduce additional complexity and may require more maintenance and monitoring effort. Option D is the simplest and most automated approach to ensure the availability of enough tape storage for backup jobs on AWS Storage Gateway.
