Restricting User Access to 3DFS Shares with ACLs

You can control the end-user access to 3DFS shares by enabling access control on the client data.

When you enable access control on client data, the access control lists (ACL) for the data are also included in the backup index. When you create a 3DFS share with ACL option enabled, the users can access only the files and folders in the 3DFS share for which they have access permissions. The access to the files and folders in the 3DFS share is given to the domain users who are logged in, based on the ACLs that are backed up.

For more information about the required ACL permissions to work on files and folders, see ACL Permissions Support.

Commvault recommends using a 3DFS Linux server that runs Red Hat Enterprise Linux or CentOS 7.0, or later operating system version.

Restriction: This option is available only for users who log on with their Active Directory credentials.

Support

Windows backups

Prerequisites

  1. Install the following on the 3DFS Linux server
  2. Download the nfs4acl_xattr.so file from the following GitHub repositories, and copy the file to the software_installation_directory/Base folder directory.

Before You Begin

  1. Enable ACL backups and perform Windows File System backups. For more information see, Restricting User Access with Access Control Lists (ACLs).

Procedure

  1. From the CommCell Console, expand Client Computers > client > File System > backup_set.
  2. Right-click the subclient that contains the backup data, and then click Manage Network Share.

    The Network Share dialog box appears.

  3. Click Add.

    The Create New Share dialog box appears.

  4. In the Share Name box, type the network share name.
  5. In the Network Storage Server list, select the MediaAgent that will act as a Network Storage server.

  9. To enable ACLs on 3DFS network share, select the Enable ACL check box.
  10. Choose one of the following options for the network share:
    • To create a read-only share with the most recent backup data, select the Refresh on backup check box.

      For more information, see 3DFS Refresh on Backup.

    • To create a share that reflects the data before the specified time, in the Restore Time list, select a date and time.

      Note: Read-only CIFS shares are created.

  11. To control the access to the share by network clients, choose one of the following options:
    • To allow all network clients to access the share, click All Clients.
