User Types

There are three types of users based on their permissions:

* *Super-users*. A special user account used for system administration. Super-user has full privileges.
* *Power-users*. A special user account which is allowed to utilize the most of advanced features. Power-user permissions are configurable.
* *Sub-user*. A special user account with restricted permissions. Sub-user permissions are configurable and are in bounds of Power-user permissions.


With Server Backup Manager, you can manage all types of users and assign permissions for browsing, backup, and restore.

{info:title}
If you attempt to create a user account and do not see options to create different user types, you must enable the associated functionality. For more information about enabling this feature, refer to [ServerBackupManager:Product Features].

h3. Super-users

A super-user has complete control over Server Backup Manager and can access and configure anything within the product. You cannot change the permissions of this type of user account.

{info:title}Most organizations provide super-user accounts to authorized, experienced individuals.
{info}

h6. Super-users and users/groups

The super-user creates power-users and sub-users, and then grants those accounts the permissions needed to use the various resources in Server Backup Manager.

All the users and groups in the protected machine are visible for super-users.
{info:title}Do not treat the super-users as power-users because you cannot add super-users to groups, nor can you assign permissions to super-users on the protected machines or volumes. Also note that super-users cannot administrate sub-users.
{info}

h6. Super-users and volumes/Disk Safes

Super-users can create, edit, delete, and import [volumes|Volumes]. Only super-users can remove a [Disk Safe|Disk Safes].

h6. Super-users and servers

h3. Power-users


h6. Power-users and users/groups

Power-users can create and administrate sub-users. Power-users also cannot assign permissions to their sub-users if they do not have these permissions themselves. 

A power-user can see only those groups to which the power-user belongs and only those sub-users that the power-user owns. The number of sub-users assigned to a power-user is unlimited if it is not restricted in the power-user *Settings*, as shown in the following image. !Create New User - sub-users.png|border=1!

* Change a disk safe's quota
* Vacuum a disk safe

Power-users can see but not edit any volumes on which they have permission. Note that the path of the volume is hidden.
