When backing up Active Directory on a Global Catalog server, Recovery Manager for Active Directory enables the backup to include the object’s membership in all groups, including those groups that reside in domains outside the object’s home domain.
This option is part of the backup creation settings. You can find it on the System State tab in the Properties dialog box for a Computer Collection. The option only takes effect when backing up Global Catalog servers.
If this option is not selected, group membership spanning multiple domains is not fully backed up, because even Global Catalog servers do not store full information about group memberships. For example, information about membership in domain local groups is only stored in the home domains of those groups.
To ensure that cross-domain group membership information is backed up
Using a Global Catalog backup created with this option ensures the complete restoration of object group memberships in all domains within the forest.
However, this option causes Recovery Manager for Active Directory to retrieve data from all domains within the forest, and therefore may slow down the backup creation in case of a big number of domains or slow network connections.
When backing up a domain controller, Recovery Manager for Active Directory can also back up the domain-based Distributed File System (DFS) namespace data located on the domain controller. DFS namespace data is backed up as part of SYSVOL. You can use the created backup to recover the domain-based DFS namespace.
To back up domain-based DFS namespace data, make sure you select the SYSVOL component on the Components tab in the Computer Collection Properties dialog box. For more information, see Modifying Computer Collection properties.
Note that Recovery Manager for Active Directory cannot back up the DFS namespace links to the actual folders and files, as well as these folders and files. Also Recovery Manager for Active Directory does not support standalone DFS namespace data.
In Recovery Manager for Active Directory, a backup for a computer or a collection of computers can be created manually, or the creation of backups can be scheduled to occur at a specific time in the future. Backups can be stored in any appropriate location on your network.
When scheduling backup creation, Recovery Manager for Active Directory employs Task Scheduler, which is an integral part of the operating system. You can access the Task Scheduler GUI by clicking Scheduled Tasks in Control Panel. The Scheduled Tasks dialog box displays all tasks scheduled to run on your computer.
Each scheduled task runs under a certain user account. Therefore, you must supply the user logon name and password of a user account when creating a scheduled task. When performing the scheduled backup job, Recovery Manager for Active Directory runs as if that user started it.
The user account under which Recovery Manager for Active Directory is running when creating backups must
When scheduling a backup job, you should ensure that the account whose credentials you are supplying meets the above requirements. If there are no trust relationships established between the domains where the Recovery Manager for Active Directory computer and the serviced computer reside, then no account can satisfy both of the above requirements. To resolve this problem, you can specify a different account to access the serviced computer.
In the “no trust” situation, when scheduling a backup job, you should use an account that meets the first of the above requirements, and configure advanced backup options so that a different account is used for access to the serviced computers, satisfying the second requirement.
