Disaster recovery solution for Windows Servers

For it o & M personnel, ensuring the stable operation of business systems is undoubtedly the most important thing in their work. There is a problem that we must all think about, that is, how to do a good job of disaster recovery solutions for servers. If one day the server suffers system or hardware faults, how can we ensure that the related enterprise services are not affected due to these reasons, rather than the server together.

For this requirement, Windows clusters are a good method. Unfortunately, not all applications can support clusters. For example, I have met a very important business system. Some functions cannot be run in the Windows Cluster Environment and I can only give up. In this case, using a backup tool for regular system backup is very important.

First, we need to select an appropriate backup tool. For Windows servers, I generally use symantec's backup tool, symantec backup exec, to back up the system. Compared with the traditional Ghsot software, it has the following obvious advantages. 1. You can perform incremental system backup instead of backing up the entire system every time. If we need to save the system backup for multiple time periods, this will effectively reduce disk space usage and greatly reduce the time for each backup. 2. You can back up the system in a Windows environment. Traditional Ghost tools need to be backed up in Dos mode, which means that business applications must be suspended each time a backup is made. Applying for server downtime is a troublesome task. Now, you can stop wasting time on this task. 3. scheduled tasks and scheduled backups are supported without manual operations. The backup system usually only operates when there are few applications at night. You certainly don't want to get up in the middle of the night to do this, so let the program automatically execute. 4. allows you to restore images from different machines to different models. This is a very useful feature. I have tried to restore a system on a dell server to an IBM machine, in many cases, we cannot guarantee that a machine of the same model is used as a backup machine. When a hardware fault occurs, this function will help you smoothly migrate the system to another machine. The following describes how to use the software. Because the installation process is very simple, you only need to follow the prompts and do not describe it here. After the installation is complete, open the program and click "run or manage backup" to create a backup task.

Schedule the backup time so that the program can automatically back up the system at the specified time.

After the backup is complete, the backup file will be generated in the specified directory. We can use this file to restore the local machine, or copy them to other machines for recovery from different machines.

When restoring, use Symantec's hardware drive disc to start. after entering the interface, click "Recover computer"
