resources

The Amazon Resource Names (ARNs) of the resources to assign to a backup plan. The maximum number of ARNs is 500 without wildcards, or 30 ARNs with wildcards.

If you need to assign many resources to a backup plan, consider a different resource selection strategy, such as assigning all resources of a resource type or refining your resource selection using tags.

If you specify multiple ARNs, the resources much match any of the ARNs (OR logic).

When using wildcards in ARN patterns for backup selections, the asterisk (*) must appear at the end of the ARN string (prefix pattern). For example, arn:aws:s3:::my-bucket-* is valid, but arn:aws:s3:::*-logs is not supported.
