Which storage option meets these requirements MOST cost-effectively?
Store the logs in Amazon S3. Use AWS Backup to move logs more than 1 month old to S3 Glacier Deep Archive.
Store the logs in Amazon S3. Use S3 Lifecycle policies to move logs more than 1 month old to S3 Glacier Deep Archive.
Store the logs in Amazon CloudWatch Logs. Use AWS Backup to move logs more than 1 month old to S3 Glacier Deep Archive.
Store the logs in Amazon CloudWatch Logs. Use Amazon S3 Lifecycle policies to move logs more than 1 month old to S3 Glacier Deep Archive.
Explanations:
AWS Backup is not necessary for moving logs from S3 to Glacier; S3 Lifecycle policies are a more direct and cost-effective method for this use case.
S3 Lifecycle policies automatically transition logs to Glacier after 1 month, meeting the requirement to store logs cost-effectively while providing easy access to recent logs.
Using CloudWatch Logs incurs higher costs for storage and access, especially for large volumes of logs. AWS Backup is not required here.
While CloudWatch Logs can be used, it is more cost-effective to store logs in S3 and use Lifecycle policies for archiving rather than relying on CloudWatch.
I measure that the answer is:
Store the logs in Amazon S3. Use S3 Lifecycle policies to move logs more than 1 month old to S3 Glacier Deep Archive.
