How to handle cloud storage data in disaster recovery

When studying how to use the cloud to ensure data security for disaster recovery, I found an interesting question: how do you deal with the data once it is created? How do you retrieve those data so that you can use them for disaster recovery?

I think a lot of people may not have considered this interesting issue, but in planning disaster recovery, we really need to consider this when we consider ensuring data security. Depending on the disaster, the answer to the question is different. In the case where the data center is intact, such as a power outage and a power outage that exceeds the duration of the emergency generator, you may need to recover the data from the cloud and then rerun them.

But a disaster that requires you to use data stored in the cloud can also damage or even damage your data center. What should you do at that time? It may be a bit late if you think about the problem after a disaster. If your data center environment is not very complex, you can find a workspace and some computers to meet your requirements. In fact, you'd better consider this when planning for disaster recovery.

There are several different situations. If your company has offices in multiple locations, you may be able to set them up as backup sites for other offices. This may require more resources from the datacenter, but you can use those resources for other projects in the absence of a disaster.

Of course, you can also sign a contract with a disaster recovery site in advance, which means you have a data center in advance, and after a disaster, you just have to reload all the data into the new datacenter. Perhaps the best solution I've ever seen is to sign a contract with a cloud vendor to build a cloud backup of the data center. This way, not only is your data safe, but you can also run your application in the cloud and make remote access. Cloud vendors will charge a fee for this, but doing so is much cheaper than buying a 24x7 backup site.

However, the real key is planning or training. Once you have decided where to store the data and how to use them after the data center resumes, you must plan the details of how to migrate. You must practice often.

The only way to make sure your current environment is able to migrate data to another office or cloud is to try to do it once. The process of this attempt can also expose the deficiencies in your planning, which will help you revise your plans and improve the viability of your planning. After the planning changes are complete, you must try again.
