You can set up one or more buckets in Amazon S3 or Google Cloud Storage (GCS) to store your expired data. For configuration details, see:

• Configure self storage in Amazon S3.
• Configure self storage in GCP.

To manage self storage locations in Splunk Cloud Platform your role must hold the indexes_edit capability. The sc_admin role holds this capability by default. All self storage configuration changes are logged in the audit.log file.

For information on how to configure DDSS self storage locations programmatically without using Splunk Web, see Manage DDSS self storage locations in the Admin Config Service Manual.
