Azure NetApp Files user and group quotas enable you to stay in control and define how much storage capacity can be used by individual users or groups can use within a specific Azure NetApp Files volume. You can set default (same for all users) or individual user quotas on all NFS, SMB, and dual protocol-enabled volumes. On all NFS-enabled volumes, you can define default (same for all users) or individual group quotas. This feature is Generally Available in Azure commercial regions and US Gov region(s).
