Cloud Staging Copy Service can create all the necessary DSA configuration for each source/target pair to run backup/restore jobs using S3.

A sample cloudstagingarea.xml file for creating a cloud staging area by Cloud Staging Copy Service defined target groups is:
{
    "name": "cs2-cloudstagingarea",
    "storage_type": "S3",
    "s3_properties": {
        "access_key_id": "ABCDEFGH",
        "secret_access_key": "AbcDEfgHIjklmNop123/456qRstUVwXyZ",
        "buckets_by_region": [
            {
                "buckets": [
                    {
                        "bucket_name": "example-bucket",
                        "prefix_list": [
                            {
                                "prefix_name": "backup",
                                "storage_devices": 100
                            }
                        ]
                    }
                ],
                "region": "us-west-2"
            }
        ]
    },
     "source_target_pairs": [
      {
        "source_system": "sourceSystemA",
        "target_system": "targetSystemB"
      },
      {
        "source_system": "sourceSystemA",
        "target_system": "sourceSystemC"
      }
    ]
}
You need to provide the following details in the cloudstagingarea.xml file.
  • s3_properties which contains s3 information as well as the region/bucket/prefix_list.
  • access_key_id
  • secret_access_key

Restrictions for Using the Cloud Staging Copy Service Defined Target Groups

Following are the restrictions for a cloud staging area created by Cloud Staging Copy Service defined target groups:
  • You need to provide the access_key_id and secret_access_key for authentication. The process does not support any other authentication methods.
  • In s3_properties you can provide only one value for each of the following parameters:
    • buckets_by_region
    • bucket_name
    • prefix_list
  • You cannot specify a source_system_target_group or target_system_target_group inside a source/target pair.
  • Cloud Staging Copy Service creates the target groups using the media servers listed in default shared target group for the Teradata system specified in the source/target pair. If a default shared target group does not exist, then Cloud Staging Copy Service cannot create a cloud staging area.
  • When you start the configuration, theCloud Staging Copy Service always atempts to create a new S3 AWS account in DSC, and does not reuse the existing account. If the access_key_id of the existing account matches with the access_key_id in new configuration, the configuration error occurs.
