Question What is best scenario for backup ?

[wesam_az]

hello
We have an airline HQ , which consists of 4 buildings , the main building , building A , building B and Building C , the server which have a system to manage customers located in the main building , All these buildings are connected wirelessly .

My question is :

What is the best way to backup data from server? what if I used QNAP NAS storage (like TS-431K) is it good solution ? or using another server for backup and in this case how would be the configuration ? or any other soultion...

Any advice would be appreciated

thanx in advance

Wireless is going to be a bit slow I suspect if you have lots of data.

The NAS itself is not a backup. They can protect against a failure of a hardware disk so you don't go down and can replace the drive without down time. It does not protect against other types of failures. If the complete nas would be destroyed or stolen for example. You also need protection against software. Could be rasomware encryption or more likely just a oops issue where someone deleted something they shouldn't have.

Now if you have data that resides on a server and copy it to the NAS in a different building that would be a good first step. You would then from time to time want to make another backup of the content of the nas on some kind of offline storage. That prevents something from damaging the server and then possibly your primary backup on the nas.

Thanx bill001g for your reply, I just want your advice regarding backup, Is it better to use a server for backup and put it in building A,B or C? Or using NAS storage in different place , or any other way??!

What is a "server?". If all it does is act as a big disk drive then that basically is what a nas does. Both are just some kind of computer that allows remote access to disks. It mostly comes down to the cost and what you might already own.

The more common function of a "server" would be to process the data on the disks into some other useful information.

Exactly how you accomplish this is not such a simple question. It depends on your application. In the simplest method you would copy files but most things are not that simple. You get into how do you copy a file that the main application server is actually writing new data to. You generally can't read a file that is open for write by another process. Something like a database has very special function that lets it make backups.

This requires much more knowledge about the application. It really functions the same as if you had a external disk sitting right next to the main server or kinda even a second disk in the main server. Where you put it really doesn't matter a lot. You want to minimize common things. You don't want say a fire in one area to destroy both copies of the data.

Note the most common problem is not that the machine blows up it would be more when someone accidentally deletes something. You have to be sure that it is not easy to delete both copies....ie you delete the main files and then the backup runs 5 minutes later and deletes that backup.
