 * `geo_redundant_backup` - (Optional) Enable/Disable Geo-redundant for server backup. Valid values for this property are `Enabled` or `Disabled`, not supported for the `basic` tier.  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. The Basic tier only offers locally redundant backup storage.
 
+* `auto_grow` - (Optional) Enable/Disable auto-growing of the storage. Valid values for this property are `Enabled` or `Disabled`. Storage auto-grow prevents your server from running out of storage and becoming read-only. If storage auto grow is enabled, the storage automatically grows without impacting the workload. The default value if not explicitly specified is `Enabled`.
