TRANSCRIPT OF VIDEO:
 
Welcome to the NetBackup Support Screencast Demo Video series.
 
These videos deliver how to demonstrations in a variety of NetBackup functions.
 
They assume fundamental NetBackup knowledge.
 
If you need basic NetBackup training, please go to http://education.symantec.com where you will be able to find a listing of instructor-led classroom training as well as self-paced computer-based courses for NetBackup.
 
This video is Configuring Exchange 2010 Database Availability Group (DAG) Backups with NetBackup 7.0.
 
For this demonstration, we will be using a master/media server running NetBackup 7.0.1 on Windows 2003 R2 SP2. The Exchange 2010 DAG will consist of 2 DAG members, each running NetBackup 7.0.1 on Windows 2008 R2. There are 2 databases in the DAG, and each DAG member has one mounted copy of a database and one replica.
 
This video does not apply to:
Exchange 2003
Exchange 2007
Non-DAG backups
NetBackup versions prior to 7.0
 
First, we need to make sure that the NetBackup client service running on each DAG member is running as an account that has the correct permissions to backup Exchange databases. For this video, the NBU client service is running as the default installed Local System Account. If a specific service account is needed for the NBU client service, we would need to make sure that account has Local System Administrator privileges, as well as the proper Admin privileges in Exchange in order to be able to backup databases.
 
Now we will go ahead and configure a policy for the backup of the Exchange 2010 DAG. We will bring up the NetBackup administration console, right click on Policies, and choose New Policy.... This will bring up the Add a New Policy dialog and we will use Exchange_DAG_backup as the policy name. We are going to keep the option to use the wizard unchecked, and click OK. This will bring up the Add New Policy window where we will configure the new policy.
 
We start with the Attributes tab. We will choose MS-Exchange-Server under Policy type. Under the Policy storage drop down, we will choose DSU for the Disk Storage Unit that had been configured earlier for this example.
 
Under Snapshot Client we will check the check box for the Perform snapshot backups option, and then click the Snapshot Client Options... button which will bring up the Snapshot Client Options dialog box. Under the Snapshot method dropdown, we will choose VSS. The default settings under Configuration Parameters should normally be sufficient.
 
 Depending on the storage used for the Exchange databases, the NetBackup client may have a hardware provider VSS writer. By default, the hardware provider VSS writer is used for the snapshot. If this is not desired, then the Provider Type settings under Configuration Parameters should be changed from 0, which is the "auto" setting, to 1, which specifies the "system" setting. We click OK to save the snapshot settings. 
 
We also see that enabling the snapshot option made available the Microsoft Exchange Attributes settings, regarding CCR and DAG, in the lower right quarter of the Attributes dialog. Under the Database backup source dropdown, we will choose the setting Passive copy and if not available the active copy. There are also the Passive copy only (or passive copy from preferred server list) and Active copy only settings available, if there is a backup scenario that calls for those specific settings. The Preferred server list configuration is where we can list specific DAG members that we prefer the backup of the passive database copies to be performed on. To use the Preferred server list, we would also choose the Passive copy from preferred server list from the Database backup source dropdown. For this 2 DAG member example, we will not need to utilize the preferred server list.
 
Now we will click on the Schedules tab to create the appropriate schedule for a full backup. We click the New... button to bring up the Add New Schedule window. Under Name we are going to use "Full" as the name of this particular schedule. Under the Type of backup, we will leave the Full Backup type. 
The four backup types are as follows:
Full Backup - which backs up the Exchange databases and transaction logs and then will have Exchange truncate the logs after a successful backup.
Differential Incremental Backup - which backs up Exchange transaction logs only and will then have Exchange truncate the logs after a successful backup.
Cumulative Incremental Backup - which also backs up Exchange transaction logs only but will not have Exchange truncate the logs after a successful backup; and
User Backup - which will allow an Exchange backup to be initiated from the client during an open Start Window. 
 
We will leave the rest of the settings at their default, and will not be configuring a Start Window for the Full Backup schedule as we will be running the backup manually for this example. Both the Start Window and Exclude Dates settings do not need any Exchange specific settings, so those will not be covered further. Now we click the OK button to save the Schedule settings.
 
Now we will click on the Clients tab to add Exchange 2010 DAG client to the policy. We click on New... and then enter the client name. 
 
For the Exchange 2010 DAG client, it is important to remember to use the clustered Exchange 2010 DAG virtual host name, and not the host name of any of the DAG members. If a DAG member name is used instead of the DAG virtual host name, NetBackup will not be able to properly ascertain the DAG environment, including the Exchange databases, the DAG members, and which DAG members one or more specific databases should be backed up from. 
 
After we enter the Exchange 2010 DAG virtual host name, we hit the <Enter> key on the keyboard, and the Hardware and Operating System columns are automatically populated.
 
Next we will click on the Backup Selections tab to configure the backup selection for the policy. We will click the New... button to enter a backup selection, and then the button to the very right of the backup selection that looks like a hand pointing to the right. This will bring up the Select Directive dialog. Under the Directive set drop down we will choose the MS_Exchange_Database_Availability_Groups setting, and under the Directive drop down we will choose Microsoft Exchange Database Availability Groups:\. We click OK and then hit the <Enter> key. Now we click OK to save the policy.
 
Before we run the backup, we are going to go over some Exchange-specific settings for the NetBackup client. 
 
In the NetBackup administration console, we click on Clients under Host Properties. We will need to check these settings on each DAG member. Since the DAG member host names are not in the list of clients, we need to click on Actions and then Configure Client... to bring up the Choose Client dialog. We enter the DAG member host name and then click OK to bring up the Client Properties dialog for DAG member. We expand the Windows Client settings and click on Exchange. Under Backup option for log files during full backups, we need to make sure that Back up all log files is selected, as that is the recommended setting for backing up replication environments such as a DAG. Under Exchange 2010 options we have the options for a consistency check before the backup. We will leave these settings checked at their default, but they can be unchecked if there is a backup scenario that calls for those specific settings. We click OK to save these settings. Again, we need to check these settings, as well as make sure Back up all log files is configured for each DAG member.
 
Now we will go ahead and run the backup. We right-click on the newly created policy, and choose Manual Backup which brings up the Manual Backup dialog. Next we click OK to start the backup, and OK again for the popup notification that a backup has started.
 
We click on Activity Monitor and can see a parent job for the DAG discovery process. It may take some time for the DAG discovery process to complete.
 
Once the DAG discovery process completes, we see parent jobs for each DAG member where a backup will take place. Depending on the Exchange environment this can take several seconds or even minutes, however. When we double-click the DAG member parent jobs and then click the Detailed Status tab, we can see the snapshot activity. For each DAG member being backed up, after the snapshot completes we will see a backup job for the databases launch. Depending on the Exchange environment this can also take several seconds or even minutes. 
 
And here we see the backup jobs have completed successfully, each with a blue man and a status 0.
 
Any final status other than 0 should be considered an unsuccessful Exchange backup and the cause should be investigated. Such a backup cannot be relied upon for a restore.
