//
//    * Error Message: The authenticated user does not have sufficient permissions

//
// Solution: Contact your system administrator to get the needed permissions.
//
//    * Error Message: The S3 bucket %s already contains an object with key

//
// Solution: Give the TargetSnapshotName a new and unique value. If exporting

//    use this same value for TargetSnapshotName.
//
//    * Error Message:  ElastiCache has not been granted READ permissions %s

//
// Solution: Add List and Read permissions on the bucket. For more information,
