[pconline technique] system crash and file loss are probably the two words we don’t want to hear. After all, behind each word means a lot of trouble. To solve this awesome problem, besides the hope of hardware, the other is the backup mechanism of the system itself. Today’s small series to introduce win10 built-in three groups of backup functions.
How many win10 backups have you used?
The backup of win10 is actually composed of three parts: “old version backup and restore”, “restore point” and “file history”. Although the three have a first and then relationship, it is not a simple substitute relationship. “Old version backup and restore” and “restore point” are mainly used for system backup and restore, while “file history” is specially used for user file recovery.
1. System image backup
System image backup can quickly restore to normal state when the system has a major failure or crash. In win10, we can click “Settings” → “update and security” → “backup” → “go to” backup and restore “(Windows 7) to enter the system image backup.

The system image backup of win10 follows the previous design of win7. If you are using it for the first time, you will see the prompt “windows backup has not been set”. Click “set backup” on the right to enter the backup process. Unlike the familiar ghost, win10 image files must be saved on a different hard disk (or NAS) from the system disk, otherwise they cannot be clicked.

After selecting the backup location, the next step is to select the backup range. Win10 will help us select the user folder in the whole system and system partition by default. Of course, you can also choose by yourself. Here, win10 supports scheduled backup. If you don’t need it, you can click “change plan” to cancel it.
Win10 will mirror the whole system by default
The backup process is relatively long. Compared with ghost, win10 system image is much longer in file size and backup time than ghost. However, due to the operation in windows, users can still continue their work during backup, even if the window is closed.
Backup time is long
The recovery process is mainly completed through win10 Advanced Startup menu. You can enter this interface by clicking “Settings” → “update and security” → “recovery” → “Advanced startup” → “restart now”, or by forcibly restarting the system for three times.

Recovery options are located in “troubleshooting” → “advanced options” → “view more recovery options”. Click “system image recovery” to enter the recovery phase. Here, win10 will select the latest image file by default. Of course, you can open the list to select by yourself.
Select the appropriate system image for recovery
The next process is similar to the system installation. After a few next steps, win10 will automatically start to recover and restart after recovery.
The recovery time is close to that of ghost
Similar to ghost, win10 system image is also partitioned (including EFI boot partition), so no matter what is on Disk C, it can be restored exactly. Moreover, because it is a built-in component of the system, win10 system image can be executed directly under windows, and the support for SSD, nvme, GPT and other new technologies will be better.
However, it also has some obvious disadvantages, that is, the backup volume is large, the backup time is long, especially the need for an independent hard disk, which is very different from ghost. Another point is that the system image of win10 will directly distribute the backup files to the root of the disk, which is very inconvenient for searching and later management. This is not as refreshing as a single. GHO.
2. System restore point
Although win10 system image is convenient, it is a typical full backup, which takes up a huge volume and is not suitable for frequent use. In win10, there is another function to realize simple incremental backup, which is system restore point.
Right click “this computer” → “properties” and click “system protection” in the setting panel to enter the system restore panel. By default, win10 system restore is off. We need to click “configure” → “enable system protection” to turn it on manually.
Turn on the system restore function
To use system restore for the first time, you need to click the “create” button below. The restore button is located in the current page and win10 Advanced Startup menu (path: Troubleshooting → advanced options → System Restore). The whole recovery process is similar to image recovery. After entering the restore panel, select the appropriate restore point (i.e. different backup time), and click next to start the recovery operation.
Select Restore Point
Unlike other backups, system restore is not a scheduled backup in the traditional sense, but a restore point (backup state) will be created automatically when win10 thinks that some operations may cause accidents (such as installing updates, installing software, uninstalling software, installing drivers, etc.). Compared with the system image, the backup content of the restore point is very small, so it will be much faster in volume and time than the former. Especially, it can be directly restored under windows, which is more convenient in practical work. However, the restore point is only the backup system file + registry, and the user file is not protected.

3. Document history
Unlike the previous two who prefer system protection, file history is specially designed to protect user files. It mainly provides two functions, one is the fast recovery of deleted files, the other is the recovery of different time versions of files.
Open settings → update and security → backup to see the file history. Like system image backup, to use this function, we need to install a separate hard disk to enable it in the menu.
Backup options are mainly divided into three parts: backup frequency, storage size and backup range. It is worth mentioning that the file history is not in the form of partition, but a separate backup of the specified folder. For example, if you have a file located in D: ABC, you need to manually add the path to the backup list. Similarly, if you feel that the backup location given by the system is not suitable, you can call it out manually.
The recovery process is also divided into two cases, one is how to recover to the previous version when the file exists, the other is how to quickly recover after the file is deleted.
First of all, when we need to restore a file to a previous version, just right-click the file and select “restore previous version”, we can see a list of files made up of copies of different periods. Find the version you need and click the “restore” button.

If the file you want to use has been deleted, you need to search the “file history” in the taskbar first. At this time, what appears in front of you is the copy of the file automatically backed up by the system at different times (similar to time mirror). Find a time before the file is deleted, then locate the file, and finally click the “restore” button under the gear icon in the upper right corner to restore the file.

Write at the end
These three groups of backup functions of win10 basically cover all aspects of daily needs. In particular, the historical records of documents are very useful in practical work. However, the backup function of win10 is a little scattered, and there is no unified standard for the operation interface, which is difficult for novices. In addition, the requirement of two hard disks for win10 backup also limits some primary users.
Generally speaking, the function is OK, but the operation logic and overall planning are far behind similar products (such as MacOS time machine). Especially as a system function, the three can not be connected head to tail, it’s hard to get a good impression! However, because of its special nature, there are not many software that can replace it in reality, so it can only rely on the later update of Microsoft.
