File System Backup Quota: Configuration

Table of Contents

Setting Quotas for File Systems

Administrators or users with User Management permissions can set file system quotas for users and user groups.

  • A user will appear in the Users list only after logging on to the CommCell at least one time.
  • The Quota feature checks for client owners whose overall file system backup usage (see Backup Usage Calculation) exceeds their quota (see Determining a User's Effective Quota). Owners who exceed 90 percent of their quota receive a warning email. Those who have exceeded their quota by more than 10 percent receive an alert email and cannot run backups until either:

    • Their usage falls below the quota when they erase some data on their owned clients
    • CommCell administrative staff increase their quota

    Backups do not start for clients owned by users whose usage is more than 10 percent over quota.

    • A user continues to be backed when over quota, provided the amount of excess is not more than 10 percent. Warning emails are sent as long as the user is over 90 percent, but below 110 percent of quota. At or above 110 percent, the alert email is sent, notifying the user that owned clients are no longer being backed up.
    • Immediately after setting quotas, the quota usage is checked at the end of any running backup jobs. Then, quota usage is checked before beginning full, incremental and differential backup jobs. Synthetic Full backup jobs run without checking quota usage.

    There are two operations to the process of setting up quotas:

    The order of these operations is not important, as long as both have been completed.

    Setting a User-Level Quota

    CommCell administrators, or any user having User Management capability for a given user or user group, can set quotas for users. (User Administration and Security - Getting Started describes setting capabilities for users.)

    Important: The CommCell Users tab shows only those users who have actually logged on to the CommServe, not all the users defined on the external domain controller.

    To set a quota for an individual backup user, follow these steps:

    1. In the CommCell Console, expand Security, then click CommCell Users.
    2. On the CommCell Users tab, right-click the user_name, then click Properties. The User Properties dialog box opens.
    3. On the General tab, clear Inherit User Group Quota Settings, then select Enforce File System Quota.
    4. Accept the default setting or enter a quota in gigabytes in the Disable data protection when quota usage exceeds box.
    5. Click OK.

    Setting a Group-Level Quota

    You can set quotas for external or CommCell user groups. A backup user who is a member of a group having a quota inherits the quota from the group. (Quota Calculation explains how a user's effective quota is calculated.)

    Making an External Group Available for Setting Quotas

    Before an external group can supply a quota, it must exist on a domain controller that the CommServe instance can reach, and be associated to a CommCell User Group.

    1. In the CommCell Browser, expand Security > Domains and look for the domain.
    2. If the domain does not appear under Domains, perform the steps given in Adding a Domain Controller for Active Directory.
    3. Expand domain and click External Groups. The External Groups tab appears.
    4. Add the group by performing the steps given in Adding an External Group.

    Setting a Quota for an External Group

    Follow these steps to set a quota for an external group:

    1. In the CommCell Console, expand Security > Domains > domain, then click External Groups.
    2. On the External Groups tab, right-click the group_name, then click Properties.
    3. In the Edit Properties of External Group dialog box, select Enforce File System Quota and change the default quota amount of 100 GB in the Disable data protection when quota usage exceeds box if you want to.
    4. Click OK.

    Setting a Quota for a CommCell Group

    Follow these steps to set a quota for a CommCell group:

    1. In the CommCell Console, expand Security > CommCell User Groups.
    2. On the CommCell User Groups tab, right-click the group_name, and then click Properties.
    3. In the User Group Properties dialog box, select Enforce File System Quota.
    4. Change the value of the Disable data protection when quota usage exceeds field to meet your requirements.
    5. Click OK.

    Adding an Owner to a Client

    To enforce a quota on a client, the client must have at least one owner. To assign a user as an owner of a client, follow the steps given in Adding an Owner to a Client, using the domain_name\user_name format.

    Note: In order to be considered for quota calculations, external group users who are added as a client owner must first log in to either the CommCell Console or Web Console at least once.
