Agent tab

NOTE

For Recovery Manager for Active Directory (RMAD) 10.1 or higher: Make sure that you use the Backup Agent version supplied with this release of Recovery Manager for Active Directory.

The Agent tab is used to specify settings for Backup Agent.

The elements of the Agent tab are defined as follows:

Note

You can configure Recovery Manager for Active Directory (RMAD) to back up data in an Active Directory® domain under a least-privileged user account and create a group named RMAD Backup Operators that will automatically grant the necessary permissions to back up data. See Using a least-privileged user account to backup data

  • Use the following account to access Backup Agent: - Allows you to explicitly specify a user account under which you want the Recovery Manager Console to access Backup Agent. When this check box is cleared, the Recovery Manager Console uses the account under which it is running to access Backup Agent. To explicitly specify a user account, select this check box, and then click Select Account to specify the account credentials.
Note

Recovery Manager for Active Directory has deprecated support for a group managed service account (gMSA) to be specified as the account to connect to the backup agent for manually triggered backups. Managed service accounts will continue to be supported for scheduled backup tasks. In accordance with Microsoft®, it is recommended to not use a group managed service account (gMSA) for interactively initiated network connections such as Recovery Manager for Active Directory manually triggered backups. To enforce this recommendation and to address the vulnerability CVE-2023-21524 (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-21524), Microsoft has limited the usages of managed service accounts with a Windows Update. By removing support for a gMSA to connect to the backup agent, this ensures an attacker does not exploit the RMAD backup agent to perform actions or access resources over the network. To utilize the benefits and security provided by a group managed service account (gMSA), we highly recommend that a gMSA account is used for the scheduled backup task. See Setting user account for scheduled tasks

  • Use preinstalled Backup Agent - Allows you to enable or disable the automatic installation of the Backup Agent. The next table explains how Recovery Manager for Active Directory behaves when this check box is selected or cleared.
Note

It is highly recommended and best practice to use a preinstalled backup agent. With preinstalled backup agents, Recovery Manager for Active Directory does not have to store highly privileged domain admin credentials for agent installation, thus increasing security of the product installation. For Recovery Manager for Active Directory 10.3 or higher this option is selected by default for all new computer collections. 

When the check box Use preinstalled Backup Agent is selected the product will have the following behavior:

  • RMAD backs up only those computers where the Backup Agent is preinstalled manually.

  • RMAD does not automatically install the Backup Agent on the computers in the Computer Collection.

  • RMAD automatically installs the Backup Agent before backing up a computer where the agent is not preinstalled manually.

  • When the backup operation completes, Recovery Manager for Active Directory removes the automatically installed Backup Agent.

  • If the Backup Agent was manually preinstalled on the computer to be backed up, RMAD will use that agent to back up data on the computer. RMAD does not remove preinstalled Backup Agent after the backup operation completes

For more information on how to install, update, and uninstall the Backup Agent or discover the Backup Agent instances that were manually preinstalled in your environment, see Managing Backup Agent.

  • Automatically configure Windows Firewall - Select this check box to have RMAD automatically configure Windows Firewall on target Windows Server® 2008-based or Windows Server® 2012-based DCs, so that RMAD can back up these DCs.

 

Schedule tab

The Schedule tab is used to specify the backup creation scheduling.

On this tab, you can use the following elements:

  • Backup creation schedule: - Displays a list of backup creation schedules for the currently selected Computer Collection.

  • Schedule enabled - Enables the backup creation schedules listed in the Backup creation schedule box. To disable the schedules, clear this check box. All the task schedules are retained, and you can enable them when needed by selecting this check box.

  • Modify - Modifies the Backup creation schedule list. In the dialog box that appears on the screen, specify new triggers or delete existing triggers.

  • User account the product will run under when creating backups: - Identifies the user account under which Task Scheduler performs the backup creation task for the currently selected Computer Collection. To change the user account, click Select Account.

  • Select Account.. - Click this button to change the user account under which Task Scheduler performs the backup creation task for the currently selected Computer Collection.

See the Best practice for schedule and retention in the Frequently asked questions section for some suggestions on scheduling of backups.

 

Alerts tab

The Alerts tab is used to specify the alert settings for the given Computer Collection.

On this tab, you can use the following elements:

  • E-mail notification - Specifies whether to send information about backup creation sessions by e-mail.

  • To: - Provides a space for you to type a recipient's e-mail address. More that one address can be entered, separated by a semicolon or a comma.

  • What to record: - Use this list to select what sort of information you want to be included in the notification e-mail message or written to the text file.

  • Send notification upon errors or warnings only - Select this check box to not receive notification unless an error and/or warning is written to the log.

  • Text file - Specifies whether to log information about backup creation sessions to an additional text file.

  • File name: - Provides a space for you to enter the path and name of a text file to be used as an additional log file.

  • View - Click this button to view the additional log (text file) using Notepad.

  • Browse… - Click this button to locate a text file to be used as the additional log file.

  • Append to file if it already exists - Select this check box if you never want to overwrite the log records, and always want to append entries.

  • What to record: - Use this list to select what sort of information you want to be included in the notification e-mail message or written to the text file.

  • Write to file upon errors or warnings only - Select this check box if you want a record to be added to the text file upon errors and/or warnings only.

 

Performance tab

The Performance tab is used to configure the throttling and performance tuning settings to be applied when creating backups for the given Computer Collection.

On this tab, you can use the following elements:

  • Enable bandwidth throttling - Limits the total bandwidth used by Backup Agent when transferring data over network links. Use bandwidth throttling to prevent excessive network traffic Backup Agent may cause.

  • Maximum network use: - Provides a space for you to specify the maximum total bandwidth Backup Agent can use when transferring data over network links.

  • Enable backup agent CPU throttling - Limits the percentage of CPU processing time Backup Agent can use on each computer.

  • Maximum CPU use: - Provides a space for you to specify the maximum percentage of CPU processing time Backup Agent can use on each computer.

  • Parallel backup tuning

    • Create backups on at most <Number> computers in parallel - Specifies the maximum number of computers serviced in parallel when creating backups. Increasing this number can speed backup creation. However, network saturation problems may occur. Symptoms of network saturation include slow network response when transferring data by Backup Agent, and possibly “RPC server unavailable” error messages when connecting to Backup Agent.

  • Data compression: - Specifies the compression method Backup Agent uses when processing the data before sending it over network links. Using higher compression reduces network traffic, but increases CPU load on the computers being backed up. If you are planning that backups created with Recovery Manager for Active Directory be used by other MTF-compliant backup tools, set data compression to None.
