How Snapshot policies are associated with volumes

Unless you specify a Snapshot policy when you create a FlexVol volume or an Infinite Volume, a volume inherits the Snapshot policy associated with its containing Storage Virtual Machine (SVM).

When you create the SVM, you can specify a Snapshot policy. If you do not specify a Snapshot policy when you create the SVM, a default Snapshot policy is associated with the SVM. The default Snapshot policy for an SVM with FlexVol volume is named default, and the default Snapshot policy for an SVM with Infinite Volume is named default-1weekly.

Note: When you upgrade the SVM with Infinite Volume from Data ONTAP 8.1.x, the default Snapshot policy changes from default to default-1weekly.

When you create a volume, you can specify a Snapshot policy. If you do not specify a Snapshot policy when you create a volume, the volume inherits the Snapshot policy associated with its containing SVM.

Note: A Snapshot policy is not associated with each constituent in an Infinite Volume, and you cannot associate a Snapshot policy with constituents. A Snapshot policy is only associated with an Infinite Volume.
