Which solution will meet these requirements?
Use AWS Backup to create a backup vault that has a vault lock in governance mode. Create the required backup plan.
Use Amazon Data Lifecycle Manager to create the required automated snapshot policy.
Use Amazon S3 File Gateway to create the backup. Configure the appropriate S3 Lifecycle management.
Use AWS Backup to create a backup vault that has a vault lock in compliance mode. Create the required backup plan.
Explanations:
Using a vault lock in governance mode allows some flexibility in managing the backups, such as being able to delete backups under certain conditions. This does not meet the requirement to not alter the files for the entire retention period.
Amazon Data Lifecycle Manager is useful for managing EBS snapshots but does not provide a comprehensive backup solution for both EC2 and S3, nor does it ensure regulatory compliance for file retention.
Amazon S3 File Gateway is designed for transferring data to S3 and does not inherently manage backups or enforce retention policies. S3 Lifecycle management is also not sufficient to prevent alteration of files.
Using AWS Backup with a vault lock in compliance mode prevents any modifications or deletions of backups during the specified retention period, ensuring regulatory compliance and data integrity.
I chart that the answer is:
Use AWS Backup to create a backup vault that has a vault lock in compliance mode. Create the required backup plan.
