This article is to share with you about the ways of data backup. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Data backup methods are: 1, remote tape library, CD library backup; 2, remote key data + tape backup; 3, database backup; 4, through high-speed fibre Channel line and disk control technology to extend the mirrored disk far away from the production machine, the mirrored disk data is completely consistent with the main disk data, and the update mode is synchronous or asynchronous.

The security and reliability of data is a very important property of enterprises, and ensuring data loss is a necessary skill for operation and maintenance engineers. The following ways to backup data are described below.

Method 1. Backup of remote tape library and CD library:

Transfer the data to the remote backup center to make a complete backup tape or CD.

Method 2. Remote critical data + tape backup:

The magnetic tape is used to back up the data, and the production machine sends the key data in real time.

Method 3. Database:

Is to establish a copy of the master database on a backup machine separate from the production machine where the master database is located.

Method 4. Network data:

In this way, the database data of the production system and the updates of the important target files that need to be tracked are monitored and tracked, and the update log is transmitted to the backup system in real time through the network, and the backup system updates the disk according to the log.

Method 5. Remote mirror:

The mirrored disk is extended far away from the production machine through high-speed fibre Channel line and disk control technology. the mirrored disk data is completely consistent with the main disk data, and the update mode is synchronous or asynchronous.

Backup, more is to ensure the security of the data, to ensure that the data can be recovered in abnormal circumstances, to ensure that the data is not leaked. For different types of data, different generation environments, data backup has different ways.

Thank you for reading! This is the end of this article on "what are the ways of data backup?". I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it for more people to see!
