# Snapshot Configuration Properties for Amazon FSx for NetApp ONTAP

Applies to: Primary array, secondary array

The Configuration tab contains snapshot configuration properties that affect the behavior of the storage array in your environment.

Tips:

- Mount Retry Interval and Mount Retry Count work together to affect the snapshot mount operation for all snapshot operations (such as backup copy, restore, and user mounts) from the graphical user interface (GUI). The snapshot mount operation is retried every 5 seconds until either the number of attempts in the Mount Retry Count property or the interval in the Mount Retry Interval property is exceeded. If the mount operation fails because of the time that it takes for the disks from an array to be refreshed and become accessible, then you can tune the mount properties by increasing the value of the properties.

- If you don't select the Auto Update Array Host Aliases check box, then you must manually enter any aliases for the array in the Array Host Aliases list. If you specify a list of aliases in the Array Host Aliases property to manually control the names for the array, then clear the Auto Update Array Host Aliases check box. Aliases are important for recognizing an array during snapshot backup jobs. An array can have multiple hostnames, IP addresses, or user configured names, which might be accessible by the client that initiates the snapshot creation.

Property | Description
--- | ---
Mount Retry Interval (in seconds) | The time interval (in seconds) after which the mount operation is not retried anymore. The default value is 300. The minimum value is 180 seconds.
Mount Retry Count | The number of retry attempts for a mount operation. The default value is 5.
Use Tunneling | If you select this option, then the snapshot operations for a Storage Virtual Machine (SVM) are executed using the cluster array instead of directly using the SVM. To use Use Tunneling, the SVM client must be associated with the cluster client using the client properties. On the network-attached storage (NAS) cluster client, set the Client Type to Cluster File Server. On the SVM client, set the Client Type to Storage Virtual Machine, and then select the proper cluster client. Use Tunneling is useful for configurations in which the client that issues the snapshot operations cannot directly access the SVM. Note This parameter is not applicable for Amazon FSx for NetApp ONTAP.
Turn off Snapshot Schedule | If you select this option, then, during the preparation phase of a snapshot backup, the file server snapshot schedule is turned off on the volumes that are being snapped. Turn off Snapshot Schedule is useful if snapshots are scheduled in Commvault, so that the file server scheduled snapshots (that is, "nightly.0" and "hourly.0") are not needed.
Turn off Snapshot Auto Delete | If you select this option, then, during the preparation phase of a snapshot backup, snapshot automatic deletion is turned off on the volumes that are being snapped. Turn off Snapshot Auto Delete is useful to prevent snapshots from getting deleted by the file server when the volume has a low amount of space.
Auto Update Array Host Aliases | If you select this option, then aliases can be added by the snapshot engine during a backup job, or while adding the array. By default, this property is selected.
Array Host Aliases | The list of aliases that can be accessed by the array. If you manually enter aliases by creating this list, then clear the Auto Update Array Host Aliases check box. The list is useful when array aliases cannot be detected automatically, or when duplicate assets might be detected between arrays that are shared by the same array access node.
DR Partner | The name of the DR partner that will perform the snapshot operations when metrocluster switchover occurs. Note This parameter is not applicable for Amazon FSx for NetApp ONTAP.
Remote Snap MA | The client name of the MediaAgent that you want to designate as the Remote Snap MediaAgent. If you configure Remote Snap MediaAgent, then the array communications are routed through this MediaAgent. For more information, see Remote Snap MediaAgent.
