Scheduled tasks are always run under a particular user account. When scheduling backup creation, you need to specify a user account that has administrator privileges on the RMAD computer as well as on the computers for which you plan to create backups (serviced computers).
When specifying a user account to run a scheduled backup creation task, you should consider whether you have explicitly specified an account for accessing Backup Agent and backup files. To check whether such an account is explicitly specified for a Computer Collection, you can use the Agent Settings tab in the Computer Collection properties. For more information, see Agent Settings tab subsection in Properties for an existing Computer Collection.
The Managed Service Account (in Windows Server® 2008 or higher) or Group Managed Service Account (in Windows Server® 2012 or higher) can be specified for scheduled tasks in the Computer Collection properties on the Schedule tab or in Task Scheduler.
MSA and gMSA requirements:
Add the $ character at the end of the account name (e.g. domain\computername$) and leave the Password field blank.
The MSA or gMSA account must be a member of the local Administrator group on the RMAD machine.
For details on how to create a gMSA account, see Using Managed Service Accounts.
In this scenario, the account under which you run your scheduled backup creation task must:
Belong to the local Administrators group on the RMAD computer.
Have the “Log on as a batch job” user right on the RMAD computer. This right is granted to the local Administrators group by default.
When you run the scheduled backup creation task, RMAD uses the explicitly specified Backup Agent access account to connect to the serviced computers and back up the data they host.
In this scenario, the account under which you run your scheduled backup creation task must:
Belong to the local Administrators group on the RMAD computer and on each serviced computer that hosts the data you plan to back up by using the scheduled backup creation task.
Have the “Log on as a batch job” user right on the RMAD computer. This right is granted to the local Administrators group by default.
If you cannot configure the scheduled backup creation task to run under a user account that has administrator privileges on the serviced computers, you may want to configure RMAD to access the serviced computers using a user account different from that under which the scheduled task is being run.
By doing so, you can access the serviced computers located in domains that have no trust relationships established with the domain where RMAD is running, solving the so-called “no trust” problem. For more information, see Setting advanced backup options.
Right-click Computer Collection and then click Properties
On the Schedule tab, click Modify.
On the Triggers dialog, click the New button and specify the task schedule settings, click OK.
Click Select Account on the Schedule tab.
In the Select Account dialog box, type the user name and password of the account you want to use, and then click OK.
When creating a backup, RMAD queries its configuration settings about what backup options to use. You specify configuration settings in the Defaults dialog box for the Computer Collections node or a Computer Collection (Computer Collection properties). You can also view and modify the settings being used by the Backup Wizard.
The Properties dialog box includes the Performance tab where you can set a number of backup options related to backup creation performance tuning.
Do one of the following:
Right-click the Computer Collections node and then click Collection Defaults.
Right-click the Computer Collection and then click Properties.
Click Advanced on the Completing the Backup Wizard page.
In the Properties dialog box, click the Performance tab.
To limit the total bandwidth used by backup agents when transferring data over network links, select the Enable bandwidth throttling check box. In Maximum network use, specify the maximum total bandwidth backup agents can use. Use bandwidth throttling to prevent excessive network traffic backup agents may cause creating backups for particular Computer Collections.
To limit the percentage of CPU processing time backup agents can use on each computer when creating backups for particular Computer Collections, select the Enable backup agent CPU throttling check box. In Maximum CPU use, specify the maximum percentage of CPU processing time backup agents can use. Use CPU throttling to prevent excessive CPU load backup agents may cause on the computers being backed up.
Under Parallel backup tuning, specify the maximum number of computers RMAD services in parallel when creating backups. The default setting is 10 computers. Increasing this number can speed backup creation. However, when RMAD services a number of computers in parallel and the connection is near its limits, network saturation problems may occur. Symptoms of network saturation include slow network response when transferring data by backup agents, and possibly “RPC server unavailable” error messages when connecting to backup agents. If you are experiencing such problems, decrease the number.
From the Data compression list, select the compression method backup agents will use when processing data before sending it over network links. Using higher compression reduces network traffic, but increases CPU load on the computers being backed up.
Default settings are used for newly created Computer Collections. By changing properties of a certain Computer Collection, you define the settings specific to that collection. Different Computer Collections may have differing settings.
The Backup Wizard uses default settings unless other settings are specified using the Advanced button on the Completing the Backup Wizard page.
When creating a backup, RMAD queries its configuration settings about what backup options to use. You specify configuration settings in the Defaults dialog box for the Computer Collections node or a Computer Collection (Computer Collection properties). You can also view and modify the settings being used by the Backup Wizard.
The Properties dialog box includes the Advanced, Local Storage, Remote Storage, and Agent Settings tabs where you can set a number of advanced backup options.
Do one of the following:
Right-click the Computer Collections node and then click Collection Defaults.
Right-click the Computer Collection and then click Properties.
Click Advanced on the Completing the Backup Wizard page.
In the Properties dialog box, click the Local Storage or Remote Storage tab. To have Recovery Manager for Active Directory store copies of backups in an additional location, select the Additional backup path(optional) check box and specify format for the path and name of the backup file. Having an additional instance of each backup stored in an alternate location may be required to ensure the availability of backups.
In the Properties dialog box, click the Advanced tab. To limit the maximum backup session time, select the checkbox Limit maximum backup time or Limit maximum DC backup time and specify the time.
In the Properties dialog box, click the Agent tab, and then do the following:
To have Recovery Manager for Active Directory initialize Backup Agent using a different account, select the Access back p agent and backup files using the specified account check box and click Select Account to supply the user logon name and password of an account that has administrator privileges on the serviced computers. Using a special account for the Backup Agent initialization may be required when RMAD cannot be configured to run under an account with administrator privileges on the serviced computers.
To have the application use preinstalled Backup Agent when backing up the Computer Collection, select the Use preinstalled Backup Agent check box.
Default settings are used for newly created Computer Collections. By changing properties of a certain Computer Collection, you define the settings specific to that collection. Different Computer Collections may have differing settings.
The Backup Wizard uses default settings unless other settings are specified using the Advanced button on the Completing the Backup Wizard page.
Recovery Manager for Active Directory can unpack backups and keep the unpacked data in the location you specify to reuse the data for subsequent starts of the Online Restore Wizard or Group Policy Restore Wizard. The use of unpacked backups accelerates operations the wizards perform during the backup data preparation step, because unpacking a backup can be a lengthy operation.
