In the information age of Korean servers, it is particularly important to do a good job of data backup. There is a certain probability that data will be damaged during transmission and exchange. Do a good job of data backup of Korean servers, which can be effectively managed. From the perspective of information security, hacker attacks are also a potential threat to Korean server data. Once attacked, they will cause varying degrees of damage. Today, we introduce several different methods of data backup for Korean servers.
How many different methods of data backup for Korean servers?
- Normal backup
This type of backup, also known as full backup, is the most common backup method. It mainly backs up the status and data of the entire system, including operating system, application software, and all data and existing system status of Korean servers. The system status in Windows Server also includes registry, startup file, COM+registry database, active directory, system volume, etc.
Normal backup is the most comprehensive and complete backup type. If there is any damage to the data on the Korean server, the data can be completely recovered through the normal backup of the previous day. However, the disadvantages of normal backup are also obvious. Because normal backup is to back up all data of Korean servers, it requires a lot of backup space, and there are many duplicate contents of these data, and the backup also takes a lot of time, so it is a complete but inefficient backup method.
- Copy backup
A copy backup is very similar to a normal backup. It is also a full backup method for the system status and all data of Korean servers. The only difference between normal backup and normal backup is that during backup, normal backup will clear the archive attribute of files, while copy backup will not clear the archive attribute. The so-called archive attribute is a mark made for a file to indicate whether the file has been backed up. The copy backup will not change any attribute of the file, so it will only back up the unmarked data, and will not have any impact on the Korean server system, nor will it affect other backup methods.
- Differential backup
Differential backup is to back up the Korean server data added or modified after the last normal backup. For example, if Korean server users perform normal backup on Monday and differential backup on Tuesday, only the data changed on Tuesday will be backed up; If a differential backup is performed on Thursday, the data changed on Tuesday, Wednesday, and Thursday is backed up. This greatly saves the storage space and backup time required for server backup in Korea. If you need to restore data, you only need two backups to restore it to the state before the disaster.
- Incremental backup
Incremental backup is to back up the data of Korean servers added or changed since the last backup. Here we need to pay attention to the following points. Differential backup refers to backing up the data that has occurred or changed since the last normal backup. Incremental backup refers to backing up the data that has changed since the last normal backup, not necessarily the last normal backup.
The above content introduces several different methods of data backup for Korean servers. For the backup method of Korean server data, users need to measure which is the most appropriate backup method according to their own conditions, and then use this method for data backup on Korean servers.
