In fact, many friends who are engaged in related work have many questions about the disaster recovery problem of building automation systems (BAS). What is a building automation system? To put it simply, it is a system that monitors and manages equipment in buildings, from air conditioners, elevators and other equipment controls to lighting and security system integration, it is not enough to manage it!

Next, let’s break down the disaster recovery of BAS and talk about it in detail. First of all, this disaster recovery planning is super important. Some researchers have said that reasonable and effective disaster recovery planning is the necessary basis for shortening BAS data loss to within 24 hours and reducing the risk of business interruption to within 5%. First, you have to evaluate the criticality of different devices in the system; second, analyze what potential threat sources will be, including natural disasters, man-made damage, technical failures, etc.! To give an analogy, if you suffer from a hurricane disaster, you may recover quickly with complete plans, but if you don’t have one, you will be in trouble.
The second data backup plan to be mentioned. Data for BAS is blood Disaster recovery for BAS, and it must be backed up regularly. We can choose daily full backup and hourly incremental backup modes, such as important real-time running data, and 15 minutes of temporary mirror storage must be established. Of course, various forms of media can be stored to prevent local accidents, such as putting tapes in A and hard disk in safe place.

The third is recovery testing, like a quarterly test is very important. Formulate test goals and indicators (you can set the bit error rate below 0.05% to meet the standards, etc.). Simulate all possible scenarios. If you don’t do simulation exercises, how can you know if your plan is enough? Relevant technology and property professional maintenance personnel are also required to participate to evaluate whether the system can be restored to a full-function state under simulated conditions.
Let’s take a look at some FAQs to make up for some details. Question: As long as the equipment is redundant and arranged in place, the detailed design of disaster recovery is not considered? Answer: It is very different. Although equipment redundancy can alleviate local problems, it is more scientific to resist systematic and comprehensive risks by relying on special disaster recovery design.

Q: How to prepare for disasters if the equipment is poor in remote rural areas and cannot interact in time with data clouds? Answer: You can choose to use a combination of manual physical storage and local independent circulation system. If you encounter a disaster, you can also provide some key control guarantees in the short term with this small system, and you can restore it synchronously after the communication link is repaired.
Let’s take a look at the differences in different disaster recovery measures! The temporary measures for simple daily regular inspections and small-scale replacement of materials can be used for small failures; the complete system-wide scanning and monitoring of the full-level system and local rapid backup and recovery are average, and the enterprise-level comprehensive disaster recovery is improved as mentioned above, which has strong recovery capabilities and high cost.
I personally think that the disaster recovery of BAS must not be relaxed at all. Each block introduced above has the truth that it should occupy an important position, so it must not be forgotten. You must do every job well in order to ensure that the system can return to operation quickly and intactly after the crisis comes. Don’t be careless about doing this. Be careful of being completely blind if something happens. It’s right for everyone to take it seriously!
