1 Configure the D2D CIFS server

Introduction

The first step in configuring the D2D device as a target for backups from HP Data Protector is to

configure the CIFS server on the D2D Backup System.

On the D2D Web Management Interface navigate to the NAS — CIFS Server page and click Edit.

The available Authentication options for the CIFS server are:

•None – All shares created are accessible to any user from any client (this is the least secure

option)

•User – Local (D2D) User account authentication

•AD – Active Directory User account authentication

More about authentication modes

None: This authentication mode requires no username or password authentication and is the

simplest configuration. Data Protector will always be able to use shares configured in this mode

with no changes to either server or Data Protector configuration. However, this mode provides no

data security because anyone can access the shares and add or delete data.

User: In this mode it is possible to create “local D2D users” from the D2D Web Management

Interface. This mode requires the configuration of a respective local user on the Data Protector

media server and configuration changes to the Data Protector services. Individual users can then

be assigned access to individual shares on the D2D Backup System. This authentication mode is

ONLY recommended when the Data Protector media server is not a member of an AD Domain.

AD: In this mode the D2D CIFS server becomes a member of an Active Directory Domain. In order

to join an AD domain the user needs to provide credentials of a user who has permission to add

computers and users to the AD domain. After joining an AD domain access to each share is

controlled by Domain Management tools and domain users or groups can be given access to

individual shares on the D2D Backup System. This is the recommended authentication mode, if the

Data Protector Media server is a member of an AD domain.

Configuring User authentication mode

These are the steps required in order to configure backups in User authentication mode:

•Create a “local user” on the Data Protector Media server.

•Create a matching “local user” on the D2D Backup System.

•Configure Data Protector services to use the local user account.

4 Configure the D2D CIFS server

1. Select or create a user on the server that will be used to administer the Data Protector media

server and access the D2D Backup System, as follows:

•Using Windows Device Manager select Users and Groups.

•Create the user.

•Add the user to the Administrators group for the local server.

2. Set the D2D CIFS Server Authentication mode to User. Note that any existing backup or restore

operations will fail if they are running when the authentication mode is changed.

3. Configure a local user on the D2D Backup System with the same user name and password

as the user created on the Windows Server (Backupuser in our example). Do this by selecting

NAS — CIFS Server on the D2D Web Management Interface and clicking Create User.

Configuring User authentication mode 5

4. In order for Data Protector to be able to authenticate with the D2D shares it must run the “Data

Protector Inet” service under the new local user account that has been created on the D2D

Backup System and on the Media server.

Change the logon account via the Services menu in Windows Computer Management. After

changing the login credentials the service must be restarted for it to take effect.

5. Now that the D2D Backup System is configured in User mode and Data Protector is configured

to connect to the D2D shares with the correct credentials, it is possible to create a D2D share

and apply access permissions to the Backupuser account.

Navigate to the NAS — Shares page, click Create Share, provide a share Name and

Description, and then set the Access Protocol to CIFS.

6 Configure the D2D CIFS server

6. After creating the share, select the Permissions tab and give Access rights to the Backupuser

account.

Configuring AD Authentication Mode

These are the steps required in order to configure backups in AD authentication mode:

•Join the D2D CIFS server to the AD Domain and configure DNS.

•Create or specify a user to be used for backups.

•Apply user permissions to D2D shares.

•Configure Data Protector services to use the correct Domain account.

Configuring AD Authentication Mode 7

To join a domain

1. Connect to the D2D Web Management Interface, as follows:

•Navigate to the NAS — CIFS Server page

•Click Edit

•Choose AD from the drop-down menu

•Provide the name of the domain that you wish to join e.g. “mydomain.local”

2. Click Update. If the domain controller is found, a pop-up box will request credentials of a user

with permission to join the domain. (Note that joining or leaving the domain will result in

failure of any backup or restore operations that are currently running.)

Provide credentials (username and password) of a domain user that has permission to add

computers to the domain and click Register.

8 Configure the D2D CIFS server

3. After joining the domain, the DNS server should be automatically updated (if a DHCP server

is used) with Forward and Reverse Lookup zone entries, however, some DNS configurations

do not allow this. In this case, or if a DHCP is not used on the network, the user must also

configure the domain’s DNS server to be able to correctly manage the D2D shares, as follows:

To configure entries manually if the DNS server does not update automatically

From a Windows client server that has domain and DNS management tools installed launch

the DNS Management Tool. (From the command line type dnsmgmt.msc or launch DNS

from the Administrative Tools menu).

Create a new Host(A) record in the forward lookup zone for the domain to which the D2D

Backup System belongs with the hostname and IP address of the D2D Backup System.

Also create a Pointer(PTR) in the reverse lookup zone for the domain for the D2D Backup

System by providing the hostname and IP address.

Configuring AD Authentication Mode 9

To create shares and grant access permission

Now that the D2D Backup System is part of a domain and can be managed, it is possible to create

shares and grant access permission to them for domain account users or groups.

1. Create a share on the D2D Backup System that is going to be used as a backup target.

•Select NAS — Shares from the D2D Web Management Interface and click Create.

•Provide a share Name and Description, then select the CIFS protocol and click Create.

2. Now that the D2D Backup System is a member of the domain its shares can be managed

from any computer on the domain by configuring a customized Microsoft Management Console

(MMC) with the Shared Folders snap-in. To do this first open a new MMC window by typing

mmc at the command prompt or from the Start Search box. This will launch a new empty MMC

window.
