Why not AwsBackup? No Glacier Deep is supported by AWS Backup https://docs.aws.amazon.com/aws-backup/latest/devguide/s3-backups.html AWS Backup allows you to backup your S3 data stored in the following S3 Storage Classes: • S3 Standard • S3 Standard - Infrequently Access (IA) • S3 One Zone-IA • S3 Glacier Instant Retrieval • S3 Intelligent-Tiering (S3 INT)

B is the most cost-effective solution. Storing the logs in S3 and using S3 Lifecycle policies to transition logs older than 1 month to S3 Glacier Deep Archive allows for cost optimization based on data access patterns. Since logs older than 1 month are rarely accessed, moving them to S3 Glacier Deep Archive helps minimize storage costs while still retaining the logs for the required 10-year period. A is incorrect because using AWS Backup to move logs to S3 Glacier Deep Archive can incur additional costs and complexity compared to using S3 Lifecycle policies directly. C adds unnecessary complexity and costs by involving CloudWatch Logs and AWS Backup when direct management through S3 is sufficient. D is incorrect because using S3 Lifecycle policies to move logs from CloudWatch Logs to S3 Glacier Deep Archive is not a valid option. CloudWatch Logs and S3 have separate storage mechanisms, and S3 Lifecycle policies cannot be applied directly to CloudWatch Logs.

S3 and S3 Lifecycle policies are the most suited here.

Ans B - S3 with Glacier Deep plus Lifecycle management

S3 Lifecycle policies to the rescue

B is correct..

Option B (Store the logs in Amazon S3. Use S3 Lifecycle policies to move logs more than 1-month-old to S3 Glacier Deep Archive) would meet these requirements in the most cost-effective manner. This solution would allow the application team to quickly access the logs from the past month for troubleshooting, while also providing a cost-effective storage solution for the logs that are rarely accessed and need to be retained for 10 years.

Option B is most cost effective. Moving logs to Cloudwatch logs may incure additional cost.

B is correct

S3 + Glacier is the most cost effective.

D works, archive cloudwatch logs to S3 .... but is an additional service to pay for over B.
