Acronis Backup Advanced Universal License
Each of these licenses enables you to install Agent for Windows on the same machine. If Agent for
Windows is already installed, you can install Agent for Active Directory by using the Acronis Backup
Advanced for Active Directory Add-On license.
To use the product in the trial mode, you do not need licenses.
Installation
Install the agent in the same way as Agent for Windows. When asked for credentials for the Acronis
Managed Machine Service, specify an existing domain user account that is included in the built-in
Administrators group of the domain controller. Otherwise, single-pass backups of Microsoft Active
Directory data will fail.
For detailed step-by-step instructions, refer to the "Interactive installation of Acronis Backup
Advanced" section of the installation documentation.
13.4 Backing up Microsoft Active Directory
To protect Active Directory, create a backup plan or use the Backup now feature as described in the
"Backup" (p. 54) section.
Follow the best practices described in the "Active Directory backup" (p. 288) section.
Ensure that the Volume Shadow Copy Service (p. 128) backup option is set to Use Volume Shadow
Copy Service and that the selected snapshot provider is not Software - Acronis VSS Provider. The
best choice is Software - System provider.
13.5 Recovering Microsoft Active Directory
Recovering a domain controller
If the domain controller is not able to boot, refer to one of the following sections, depending on the
number and availability of domain controllers in your environment:

"Recovering a domain controller (other DCs are available)" (p. 293).

"Recovering a domain controller (no other DCs are available)" (p. 294).
Recovering Active Directory data
If the Active Directory database files or the SYSVOL folder are corrupted but the domain controller is
able to start in normal mode, you can recover only the Active Directory data.
Use one of the following methods:

"Re-promoting the domain controller" (p. 316)
This is just a replication of all the Active Directory data from other DCs.

"Recovering the Active Directory data from a single-pass backup" (p. 316)
This method enables you to recover all the Active Directory data regardless of availability of
other DCs. If other DCs are available, you can also perform an authoritative restore of individual
Active Directory objects. For example, you can restore an unintentionally deleted user account or
computer account. Other objects will be replicated from other DCs.
