Active Directory is a Tier-0 service that sits at the center of nearly every enterprise identity stack. More than 90% of global businesses and 95% of the Fortune 1000 use Active Directory (AD). It is the identity system of record that powers these enterprises, syncing data to several line-of-business applications to drive automation and security.
Active Directory is also the technology that is the most under attack. Mandiant reports that nearly 9 in 10 intrusions involve Active Directory. Adversaries target Active Directory because of its ubiquity and the extensive blast radius once breached.
So that means when AD goes down, everything goes down. Traditional forest recoveries can take weeks and risk re-infecting your systems. Rubrik Identity First Recovery (IFR) decouples the OS from your identity data to restore a clean directory up to 56% faster.
ADFR: A Manual Recovery Nightmare
A full Active Directory Forest Recovery (ADFR) is one of the hardest tasks in disaster recovery scenarios. Microsoft's own ADFR guide recommends a 29-step, largely manual playbook spanning more than 100 pages. It requires isolating domain controllers, seizing FSMO roles, cleaning replication metadata, resetting the KRBTGT account twice, rebuilding trusts, and redeploying one domain at a time.
The challenge for the Identity and Access Management (IAM) team is that this process can take weeks. While ADFR is in progress, the business stays offline. When identity is down, everything is down. Therefore, identity needs to come back online for a business to quickly recover from a cyber attack.
When You Need the Directory, Not the Whole Machine
Rubrik has long supported ADFR through System State Recovery (SSR) and Bare Metal Recovery (BMR), and both remain the right tool for surgical jobs like restoring a single failed domain controller. But both methods bind the Active Directory database to the underlying operating system it was backed up from. In a full forest compromise, that coupling creates two problems:
Environment Rigidity: Traditional recovery solutions expect the target machines to closely match the source machines, including the same hypervisor, patch levels, drivers, and disk layouts. In real disaster recovery scenarios, customers usually require recovery to new cloud instances or different hardware. Mitigating these small discrepancies in machine configurations was time consuming and required the use of the comapny's gold image at the exact moment speed matters most.
The Malware Persistence Trap: Traditionally, malware overwhelmingly lives in OS binaries, DLLs, or registry hives. Restoring the full image with the operating system meant an extra step of fully scanning the OS on the target system before starting the restore.
Introducing Identity First Recovery for Active Directory
Rubrik Identity First Recovery gives you two options to recover Active Directory:
An established image-based restore for recovering a single failed domain controller
IFR as an option in an Active Directory full-forest compromise scenario, where a clean foundation and fast recovery matter
Rubrik now separates the NTDS.dit from the OS, enabling teams to recover just the directory data into a clean Windows instance. Rubrik extracts the ntds.dit (the core database of all AD objects, schema, and hashes), plus the SYSVOL data, and reintroduces them into a fresh, user-provided Windows install across cloud and on-prem.
This is critical because typical attacker persistence mechanisms (such as rootkits, malicious binaries, tampered DLLs, and compromised registry hives) might reside in the operating system layer. IFR discards this data and only recovers the directory itself, including the Active Directory database, the NTDS.dit, and SYSVOL. The OS mechanisms are not recovered to the new host, removing the need to scan the target system and have parity with the previous version of your DC's OS.
How Identity First Recovery Works
Rubrik IFR brings three major capabilities:
Security Built into the Recovery Process: Through deep integration with Rubrik's threat hunting and threat monitoring capabilities, every Active Directory snapshot is checked against Rubrik's threat intelligence feeds, looking for known indicators of compromise, such as adversary-created GPOs and planted scripts. This evaluation happens continuously as part of Active Directory protection. Rubrik's threat hunting and threat monitoring integration enables IAM teams to quickly identify the clean point in time without raising a separate ticket for security. This gives them the speed to quickly identify a clean point in time and start the recovery process, rather than raising a ticket for the security team and waiting days to pinpoint the clean point in time.
Automated Target Host Preparation: With IFR, Rubrik requires a customer to provide a plain Windows Server instance as the target host. Rubrik automates several steps in the host preparation process, including verifying the local system account, renaming the host to assume the source domain controller's identity, installing the ADDS role, and promoting the new domain controller automatically. Rubrik then restores the Active Directory data, parses the SYSTEM registry hive from the mounted snapshot to recover the original boot key, and re-encrypts the password encryption key against the new host's boot key.
Recovery to Any Clean Target: With IFR, customers can recover Active Directory to any fresh Windows instance provided without matching the source machine's patch level, drivers, or hypervisor. IFR becomes an any-to-any process, as long as the target machine's Windows OS is matching that of the source's Windows OS.
How Identity First Recovery Delivers Business Value
In the simplest terms, using IFR means that you don’t have to burn down your whole house to kill a spider in the bathtub. IFR delivers:
Proactive Identification of a Clean Point in Time: This gives IAM and security teams the confidence to quickly recover to a clean point in time rather than rolling back to a potentially infected stale snapshot. IAM admins can stop waiting on security to vet and validate different snapshots via a separate tool.
Accelerated ADFR: Moving a roughly 2 GB identity database instead of a 60 GB system image means less data to transfer and a faster path to recovery. In our internal testing, Rubrik Identity First Recovery cut recovery times by up to 56% for Active Directory database sizes of around 500 MB. This is a significant enhancement for customers using Identity First Recovery, where speed is of the essence.
Expanded Recovery Beyond your Data Center: The OS layer is independent of the backup, so your AD recovery is no longer tied to the host platform. With IFR, you can recover an AD forest from physical hardware onto VMs, across a hypervisor upgrade, or onto cloud instances, provided the target host runs the same major Windows Server version as the source.
Rubrik Identity First Recovery brings a fundamental change to the Active Directory recovery process: the directory is no longer tied to the machine it originated from. Rubrik intentionally chose to solve the hardest use case first, bringing back an entire forest after a cyber event onto whatever clean infrastructure is available.
With IFR, an Active Directory forest recovery process stops being a manual, environment-specific exercise and becomes one that can be automated end-to-end.
Rubrik has many exciting enhancements to IFR is coming in the next few months and we're thrilled about all of the new opportunities this foundational investment has opened up.
