Types of quotas

Quotas can be classified on the basis of the targets to which they are applied.

The following are the types of quotas based on the targets to which they are applied:

User quota
The target is a user.

The user can be represented by a UNIX user name, UNIX UID, a Windows SID, a file or directory whose UID matches the user, Windows user name in pre-Windows 2000 format, and a file or directory with an ACL owned by the user's SID. You can apply it to a volume or a qtree.

Group quota
The target is a group.

The group is represented by a UNIX group name, a GID, or a file or directory whose GID matches the group. ONTAP does not apply group quotas based on a Windows ID. You can apply a quota to a volume or a qtree.

Qtree quota
The target is a qtree, specified by the path name to the qtree.

You can determine the size of the target qtree.

Default quota
Automatically applies a quota limit to a large set of quota targets without creating separate quotas for each target.

Default quotas can be applied to all three types of quota target (users, groups, and qtrees). The quota type is determined by the value of the type field.
