The reason why the backup server is unstable is

"unstable" is not a common word for some departments, but for the storage administrator this word is enough to make them crazy. When a backup server becomes unstable or unreliable, it's not just a fault …… but a fault. This makes it difficult to track down the cause of the failure. For backup servers, this problem is quite acute, because the problem with this server can cause problems with any other server that contacts [mdash;— from the backed up network to the file system. This diagnosis is quite complicated. Zhejiang computer repair Xiamen computer repair Although the details of the instability of the backup server are usually very (some can be said to be "crazy", detailed release, there are still some general principles you can use to make a basis. Changchun Computer Repair Perhaps the most common cause of instability in backup servers is to modify system parameters to improve performance or other reasons. To improve the performance of a server, you can have a lot of means to implement it. However, in some ways, if you modify it, it may make some systems unavailable in some ways. Because these instability is not always displayed in applications or servers that have been mixed. The most important thing is to keep a detailed record of the changes that are easy for all administrators to access. Another common cause of server instability is modifications made within the system, such as updating or installing plugins. Microsoft's Windows XP Service Pack 2 causes many remote backup servers to fail because it activates the Windows XP firewall by default and the backup software cannot transfer data through the firewall. This situation is generally easier to identify and can generally be resolved by restoring the system to a previous, stable version until a more stable, more permanent fix is ​​discovered. In the case of this update or the addition of new hardware and software, your best resource is the manufacturer or manufacturer. The third reason that the backup server is unstable is some of its own changes. A normal process, accumulated hardware failure, or changes in the way the system is used can cause these unstable conditions. For example, within Microsoft's SBS, two common causes of backup failures are: An SBS log file adds more than 64 megabytes to abort backups caused by excessive read and write operations on the device. Your log files are your best friends. You should read the logs of these backups every day, and at least roughly browse the logs of your related backup events. When your backup server starts to have problems, you You need to take a general look at them, and you might read the increased event log to help you find what caused the server to be unstable. Be sure to pay special attention to the error messages generated by the backup, even if the backup has been completely successful. The incredibly fault-tolerant capabilities of modern backup systems can keep the work going —— even if some backup processes report some errors. When checking your logs, pay special attention to unclear timeouts. An unclear timeout may often mean that some inefficient operation —— at least —— can mean that you may have bigger problems elsewhere in the system. This is especially true when the backup process is running in the background and has a low priority compared to regular work. Because backups get a small portion of system resources, when something goes down, backups often become the first timeout process. (Of course, just complicate things, there are some errors that don't need to be noticed. Check with your vendor to see what they are telling you about the error message.) A good question is to ask yourself when you When the backup server has an abnormal situation, is there any other thing that uses the same resources after the server is started? Obviously this is a very wide problem because a backup server is associated with many other IT architectures, and hardware. , software, storage devices and other devices interact with each other. When a real problem arises, the first priority is to stabilize the backup server as soon as possible. Frequently, the server can be stabilized by reducing the load on the backup system (reducing some I/O or investing more resources).
