Reliable Backup and Recovery for Operational Technology (OT) Environments

Frequently asked questions

• How can manufacturers back up OT systems without interrupting production?

  Acronis can create live, image-based backups of supported x86 and x64 OT systems while they remain in operation. This helps protect operating systems, applications, configurations and data without scheduling a production shutdown for every backup. Because industrial environments vary, backup frequency, application-consistency settings and recovery procedures should be tested against the requirements of each workload before deployment.

• Can legacy Windows OT systems be recovered to new or different hardware?

  Yes. Acronis supports backup and recovery for a range of legacy Windows systems commonly found in operational technology environments, subject to documented version and update requirements. If the original industrial PC or server fails, Acronis Universal Restore can recover the system image to dissimilar hardware by applying the drivers needed for the replacement machine to boot. Application or control-system licenses tied to a MAC address, disk ID or other hardware identifier may still require reactivation with the software vendor.

• How does OT backup and recovery work in an air-gapped or offline network?

  Acronis Cyber Protect Local is designed for on-premises environments with limited or no internet connectivity. Licensing can be applied offline. Protection updates can be distributed through an approved proxy or a multihomed management server, or transferred manually to the management server for distribution to protected systems. This enables an organization to maintain network isolation while centrally managing backup and recovery; the exact update workflow should follow its OT security and change-control policies.

• How does Acronis protect OT backups from ransomware?

  Acronis Active Protection monitors for behavior associated with ransomware, such as rapid file encryption, and can alert administrators, stop a malicious process and revert supported file changes. Immutable storage adds another layer by preventing protected backups from being altered or deleted during a defined retention period. If a system was encrypted before a backup ran, that backup may contain encrypted data, so organizations should maintain multiple recovery points and regularly test that clean restore points are available.

• Can Acronis back up PLC, DCS and SCADA environments?

  Acronis does not directly back up every proprietary PLC or DCS from its native console. A common approach is to use the control-system vendor’s tools to export PLC or DCS programs and configurations to an engineering station, then protect that station and its files with Acronis. Supported x86 or x64 systems — such as many SCADA servers, HMIs, engineering workstations and historians — can be protected with image- or file-based backup. Compatibility and application-consistency requirements should be confirmed for each vendor and system version.

• Where can OT backups be stored?

  Acronis supports local, network and cloud backup destinations, depending on the deployment and connectivity available. An OT recovery design can keep a local copy for fast restoration and replicate another copy to a separate site or supported cloud storage for resilience. Supported immutable storage can further protect selected backups from deletion or tampering. The right combination depends on recovery-time objectives, data-residency rules, bandwidth and the level of isolation required by the plant.

• What recovery options help reduce downtime after an OT system failure?

  Acronis supports several recovery levels: individual files and folders, complete systems, recovery to the original hardware, and recovery to dissimilar hardware with Universal Restore. This gives operations teams a way to match the response to the incident — restoring a deleted configuration quickly or rebuilding a failed industrial PC or server. The best results come from documented recovery procedures, suitable boot media and regular restore tests that verify drivers, applications, licenses and OT communications before an emergency.
