OT Backup Management
In today's interconnected world, safeguarding ICS/OT systems is crucial for critical infrastructure businesses. With the increasing volume of data being received, stored, and transferred by organizations, data has become one of their most valuable assets. Losing data can have severe consequences for an organization's identity, reputation, operations, and financial stability.
In critical infrastructure setups like manufacturing, O&G, and energy sectors, OT systems and SCADA play a vital role. As part of an effective business continuity and disaster recovery plan, ensuring the availability of ICS/OT systems is paramount. This includes backing up operator workstations, controllers, PLCs, IO modules, and SCADA servers, as well as network components like switches, routers, and firewalls.
With the rise of cyber-attacks and the increasing coherence between OT and IT systems, organizations must have a recovery process in place to minimize the risk of data loss and other disruptions to operations. Backup storage solutions in the OT network environment are essential for swift recovery in the face of cyber incidents or system failures.
Developing a comprehensive backup plan is crucial to ensure the availability of critical data and system backups. Key elements to consider in an OT network environment are:
Selection
Identify and prioritize which systems and network devices require backup.
Backup Frequency
Determine how often files should be backed up based on their importance and operational needs.
Multiple Copies
Create redundant copies of backed-up files in different locations for added protection.
Retention Period
Determine how long backup copies should be retained based on regulations and business needs.
Backup Location
Choose the right backup location, such as offline storage media, to safeguard against cyber threats.
Automated Backup Solutions
Use automated tools to streamline the backup process and reduce human error.
Having an efficient data backup and restoration process is essential for quick system recovery in the event of data loss.
Choose the Right Backup Strategy for Your Industry
Backing up data is essential for any industry, but with so many options available, it can be difficult to choose the right strategy. Full backups, incremental backups, differential backups, mirror backups - each designed to tackle different concerns and vulnerabilities.
- Full Backup: Backup all your data files and folders in one go for shorter restoration times. However, it requires larger storage and takes longer to complete.
- Incremental Backup: Quickly backup changes made since the last backup, but restoration times can be high.
- Differential Backup: Backup changes made since the last full backup with better restoration times than full or incremental backups.
- Mirror Backup: Create exact copies of your source data files for added protection.
Using a combination of backup types ensures a robust disaster recovery plan. Follow the 3-2-1 backup rule: 3 backups, 2 on-site but on different media, and 1 off-site.
- External hard drives: Easily portable and simple to use, but can experience data loss over time.
- Backup software services: Select required data for backup with added encryption for protection against cyber threats.
- Tape backup: Store large amounts of data on a single tape, but restoration times can be lengthy.
- Cloud backup: The most popular solution for its safety and easy accessibility. Choose between public, private, or hybrid cloud storage options.

FREQUENTLY ASKED QUESTIONS
OT Backup Management is essential because it ensures the availability and integrity of data in ICS/OT systems. This is vital for maintaining operational continuity, protecting against data loss, and mitigating the impact of cyber-attacks or system failures.
Key elements include identifying which systems and network devices need backup, determining backup frequency, creating redundant copies in different locations, setting retention periods, choosing the right backup location, and using automated backup solutions.
Types include Full Backup (all data at once), Incremental Backup (changes since the last backup), Differential Backup (changes since the last full backup), and Mirror Backup (exact copies of source data). The best type depends on your specific needs for speed, storage, and restoration times.
Zeali provides a comprehensive approach that includes assessing and analyzing your OT environment, creating tailored backup strategies, automating backup processes, and offering real-time monitoring. They also ensure data integrity with encryption and strict access controls, and provide regular reporting and compliance assurance.
Zeali recommends options like external hard drives, backup software services, tape backups, and cloud storage. Each has its pros and cons—external hard drives are portable but can be unreliable, tape backups are cost-effective but have slow restoration times, and cloud backups offer safety and accessibility but may involve varying costs and security considerations.
