With RMAD, you can schedule a backup creation job to run at specific times, either once or at recurring intervals. Only backup jobs for Computer Collections can be scheduled. You can schedule a backup job by modifying properties of an existing Computer Collection or you can use the Backup Wizard to schedule a backup job. When you use the Backup Wizard for backup scheduling, the wizard creates a new Computer Collection, and schedules a backup job for that Computer Collection.
Right-click a Computer Collection and then click Properties.
On the Schedule tab, click Modify.
In the Triggers dialog, click New and then specify the task schedule settings and click OK.
On the Schedule tab, click Select Account and enter the user logon name and password of the account under which you want to run the scheduled task.
When you schedule backup creation, a new scheduled task is created and assigned to the Computer Collection.
Start the Backup Wizard and follow the provided instructions.
On the When to Back Up page, click Later (configure backup scheduling), and then click the upper button labeled Change.
In the Triggers dialog box, click New and then specify the task schedule settings and click OK.
In the When to Back Up window, click the lower button labeled Change and enter the user logon name and password of the account under which you want to run the scheduled task.
Click Next and follow instructions of the wizard to complete the operation.
When you schedule backup creation with the Backup Wizard, a new Computer Collection is automatically created for the computers you have selected in the wizard, and a new scheduled task is assigned to that Computer Collection. Later, you can change, add, or remove backup schedules for that Computer Collection.
You can temporarily disable the backup creation task scheduled for a particular Computer Collection, without affecting the other collections. To do so, on the Schedule tab in the Properties dialog box for that Computer Collection, clear the Schedule enabled check box.
You can manage backup schedule by modifying Computer Collection properties:
Right-click a Computer Collection and then click Properties.
On the Schedule tab, click Modify.
Use the Triggers dialog box to add, remove, or change existing schedules.
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.
