If the Active Directory Domain Controller (AD DC) becomes unavailable for whatever reason, then users cannot log in and systems cannot function properly, which can cause disruption to business activities. With a good backup and recovery strategy implementation, your organization can easily recover after your domain controllers crash. The ideal DC to backup should be the one running the Flexible Single Master Operation (FSMO ) role. If you have multiple DCs running, you need to back up at least one of them. It’s therefore important to develop and implement a clear active directory backup policy. Although active directory services are designed with high redundancy (if you deployed several DCs in your network). If your domain controller crashes, your network and by extension, business activities come to a halt. You only really should have to back up one of the domain controllers. You probably don’t need to back up every single domain controller, to get a good backup of the AD. In such a situation, you would need to restore it from a backup. Multiple domain controllers can fail at once, accidental or deliberate deletion of all the accounts or critical organizational units (OU) can occur, entire database corruption can occur, viruses, and ransomware or some other disaster could wipe out all domain controllers. You should still be doing a backup of the active directory whether you have multiple domain controllers or not. However, having multiple domain controllers is not enough justification to not do a backup. Its best practice is to have multiple active directory domain controllers with fail-over functionalities so that when one fails, you would still be able to recover even without a backup. Having no backup strategy whatsoever could put the entire organization at risk. FOLDER BACKUP SYSTEM WINDOWSWhen planning for a backup strategy, it is important to consider such integration, especially because of the immediate impact it has on the AD.ĭo you need to back up the active directory?Īctive Directory is one of the most important components in any Windows network. FOLDER BACKUP SYSTEM REGISTRATIONActive Directory is tightly integrated with Windows protected system files, System Registry of a domain controller, Sysvol directory, COM+ Class Registration Database, and cluster service information. The database is divided into several sections that contain different types of information-a schema partition (which determines the AD database design), configuration partition (information about AD structure), and domain names context (users, groups, printer objects). The Ntds.dit file is used to store the AD database. Common types of AD objects include users, computers, applications, printers, and shared folders. The Active Directory database (directory) has a hierarchical tree-like structure and contains information about the AD objects in the domain. FOLDER BACKUP SYSTEM PASSWORDTo ensure that the DCs stay up to date, changes made to the directory on one DC such as change of password are also replicated to the other DCs. Some organizations have multiple DCs, and each one has a copy of the directory for the entire domain. The servers that run AD DS are called Domain Controllers (DCs). The main Active Directory service is Active Directory Domain Services (AD DS), which is part of the Windows Server operating system. A tree is a collection of domains, and a forest is a collection of trees. A domain is a group of objects (such as users or devices) sharing the same AD database. The AD layout follows a tiered structure made up of domains, trees, and forests. Active Directory and Azure Active Directory are distinct but can work together to some degree if your organization has a hybrid deployment (on-premises and cloud). Microsoft cloud infrastructure uses Azure Active Directory, which serves the same purposes as its on-premises counterpart. It is now included in all subsequent Windows Server operating systems, enabling network administrators to create and manage domains, users, objects, privileges, and access within a network.ĪD is great at managing traditional on-premises Microsoft infrastructure but not cloud environments. It was first introduced in Windows Server 2000 for centralized domain management. Active Directory (AD) is a Microsoft proprietary directory service developed for Windows domain networks.
