BAS Disaster Recovery Practical Guide: Basic Cognition And Key Module Analysis

Practical Guide to BAS Disaster Recovery

During the operation of the building automatic control system (BAS), sudden situations such as power outages, equipment failures, and software paralysis are like a sudden storm, which may paralyze the entire system at any time, causing huge troubles to building management. At this time, a comprehensive disaster recovery plan becomes particularly important.

Basic knowledge of BAS disaster recovery

To put it bluntly, when the BAS system cannot operate normally due to an accident, the system can quickly return to normal working state through pre-developed processes and technical means, and reduce losses caused by system paralysis. This not only affects the normal operation of equipment in the building, but also directly affects all aspects such as energy consumption and personnel safety.

Four key modules for disaster recovery

To recover BAS disasters well, it is not something that can be done with just a slap in your head. It has to start with four core modules:

1. Data backup strategy : This is the foundation of recovery! You should back up key data such as BAS configuration data, operation logs, and history records regularly - for example, every day. You also need to note when backing up that the copy cannot exist in only one place. It is best to save one copy locally and another copy on the server. For example, the cloud platform backup that is often used now is quite reliable. You also need to regularly - for example, every month, test whether the backup file can be restored normally. Don’t wait until there is a problem before you find that the backup file is broken, so it will be too late to cry!

2. Emergency plan construction : This is like a combat map before the expedition. Do you think it is important? It is necessary to clarify the response process for different types of disasters, such as what to do if the power outage is lost, and which spare tire solution should be started if the server crashes. The labor needs to be divided into specific departments, such as the engineering department is responsible for equipment inspection and the IT department handles software problems. Emergency supplies must also be prepared in advance, such as backup servers and tool boxes.

3. Device redundant configuration : Important hardware cannot be just a single one. Take the control module as an example. The main and backup switching function should be used in key areas. Once the main module fails, the backup can be immediately put on the table - just like a stand-in actor, saving the scene in one second! It is also recommended to use dual-machine hot standby for core devices such as network switches to ensure that data transmission is not interrupted.

4. Special personnel training : No matter how good the technology or the good process is, it will be useless if no one knows how to operate it! Engineers and operation and maintenance personnel must be organized regularly for training, and simulate emergencies for practical drills. Everyone is required to memorize the operation steps, such as how to complete the server restart within half an hour, how to manually switch the control mode, etc.

High frequency questions and answers

Q: How often does it take to backup data to be the most OK?

A: It is recommended to determine the frequency of data change. If the configuration data is not changed frequently, it is OK to back up once a week; but it is best to back up data such as running logs that are frequently updated every day, or even once every few hours. Anyway, more backups are better than less backups. If you are not afraid of ten thousand, just be afraid of if you are not afraid of it!

Q: Is it necessary to prepare for disasters for BAS in small buildings?

A: Absolutely! Even if it is a small building, the system is paralyzed and the elevator is out of service and the air conditioner is ineffective, which has a significant impact. You don’t have to do too complicated solutions, such as first doing basic data backup and simple manual emergency operation guides, which can at least deal with common problems.

Comparison table of different recovery plans

Recovery Type	Applicable scenarios	Advantages	shortcoming
Cold preparation	Small projects with relatively tight funds	Low cost, no maintenance required	Recovery speed is very slow, you may have to wait for several hours
Wenbei	Medium-sized buildings, with average recovery time requirements	The recovery time is OK, about 1-2 hours	Backup device inspection must be started regularly
Hot ready	Large commercial buildings, hospitals and other places with extremely high requirements	Switching at seconds has basically no effect	Spend a lot of money, and you must always ensure that backup equipment is running online

Personal opinion: BAS disaster recovery cannot be restored before it can be remembered when a disaster occurs. You must plan in advance and plan ahead. Looking at it from a small point: Do every data backup and pay attention to every device status so that the system can firmly gain a foothold in various emergencies.
