Maximum number of Snapshot copies for volumes that are mirrored

The maximum number of Snapshot copies that a FlexVol volume in a mirror relationship can contain is 251. The maximum number of Snapshot copies that an Infinite Volume in a data protection mirror relationship can contain is 250.

For FlexVol volumes, whenever an update to a data protection mirror copy or set of load-sharing mirror copies occurs, Data ONTAP creates one new Snapshot copy. For Infinite Volumes, whenever an update to a data protection mirror copy occurs, Data ONTAP creates one new Snapshot copy. You should consider this as you manage the number of Snapshot copies on the source volume. You must keep the number of Snapshot copies far enough below the limit that updates to the mirror copy do not exceed the limit.

You should allow a maximum of 251 Snapshot copies for a FlexVol volume in a SnapVault relationship. By using a maximum of 251 Snapshot copies, you provide yourself a buffer in which you can manage your Snapshot copies before reaching the hard 255 Snapshot copy limit.
