If you have more than one domain controller, you should back up at least one of them. It is obvious that if you have just one domain controller in your infrastructure, you should back up this DC. At least one domain controller in a domain must be backed up Let’s take a look at some general recommendations for Active Directory backup. IIS meta folders (if Microsoft Internet Information Services are installed on your Domain Controller).Certificate services database (if your Domain Controller is a certificate service server).DNS zone information integrated with Active Directory.The list of all components which are integral parts of the Domain Controller system is as follows: What Data Must Be Backed Up?Īccording to the previous section, you need to make a copy of not only Ntds.dit, but all components integrated with Active Directory. Such integration has direct influence on the Active Directory backup strategy.ĭesigned for businesses of all sizes, NAKIVO Backup & Replication offers complete data protection for all of your production workloads, including VMware vSphere Backup, Hyper-V Backup, Microsoft 365 Backup and more.

Usernames and passwords checked by Kerberos authentication server are stored in the LDAP directory (in case of using Active Directory).Īctive Directory is tightly integrated with the DNS Server, Windows protected system files, System Registry of a domain controller, as well as the Sysvol directory, COM+ Class Registration Database, and cluster service information. Kerberos is a secure authentication and single sign-on protocol that uses secret key cryptography. LDAP (Lightweight Directory Access Protocol) is an open cross-platform protocol used for accessing directories (such as Active Directory) which also has access to directory services authentication by using user name and password. The Ntds.dit file is used to store the AD database.Īctive Directory uses LDAP and Kerberos protocols for its function over the network. The Active Directory database has a hierarchical tree-like structure. The database is divided into several sections that contain different types of information – a schema partition (which determines the AD database design including object classes and their attributes), configuration partition (information about AD structure) and domain names context (users, groups, printer objects). Active Directory Working PrincipleĪctive Directory is a management system that consists of a database where the individual objects and transaction logs are stored. With the help of Windows Server Backup, you can perform seamless backup of your Active Directory data, ensuring that your application data remains transactionally consistent under any circumstances. NAKIVO Backup & Replication is an all-in-one backup and site recovery solution that helps you protect your data and follow Active Directory backup best practices. Today’s blog post explains Active Directory backup best practices including effective methods and tools.

That’s why backing up your Active Directory is important. If the Active Directory Domain Controller (AD DC) becomes unavailable, then related users cannot log in and systems cannot function properly, which can cause troubles in your environment. MS SQL and MS Exchange usually require Active Directory. Administrators can manage computers added to the domain centrally, which is convenient and time saving for large and distributed infrastructure. By Michael Bose Active Directory Backup Best PracticesĪctive Directory is a widely-known service for centralized management and user authentication in Windows-based environments.
