A domain controller is a server that manages user accounts, group policies, network resources, and security authentication requests within a Windows domain. A domain controller backup is the process of creating a copy of the data and system state of a domain controller.

Domain controllers store critical information, including user credentials, security policies, and domain configuration. A backup strategy for domain controllers is vital for:

• Disaster recovery: Restore critical data swiftly in case of a disaster, hardware malfunction, or cyberattack.

• Business continuity: Minimize downtime and quickly resume your organization's operations.

• Data integrity: Protect sensitive data against data corruption, unauthorized changes, or breaches and comply with industry regulations.
