 * `creation_source_server_id` - (Optional) For creation modes other then default the source server ID to use.
 
-* `geo_redundant_backup_enabled` - (Optional) Turn Geo-redundant server backups on/off. This allows you to choose between locally redundant or geo-redundant backup storage in the General Purpose and Memory Optimized tiers. When the backups are stored in geo-redundant backup storage, they are not only stored within the region in which your server is hosted, but are also replicated to a paired data center. This provides better protection and ability to restore your server in a different region in the event of a disaster. This is not support for the Basic tier.
