1. Put the mouse in the lower right corner-Call up the super button-Select Settings-Control Panel-System and Security-File History;
2. By default, the file history function is turned off, and you can turn it on by clicking Start. For the first time, you need to select a drive, an external drive (removable hard disk or USB flash drive) and a network location. The network location needs to establish a homegroup, and then back up the files to the hard disks of other members of the homegroup. Because the author has not established a family group, only the related functions of using USB flash drive are shown here, and the use of network is similar.
3. Unfortunately, file history does not support active selection of drive folders, but only supports linking to libraries, but in fact, we can associate files that need to be backed up with libraries. By default, all files in the library are backed up. If we don't need to back up a lot of useless HD video or music files, we can select unnecessary library files in the exclusion folder, and a lot of unimportant video files will be deleted in the exclusion folder.
4. Click Run Now to back up the library file. The speed depends on the size of the files in the library. First time, the speed is slow. Now it shows that the file history is backing up your copy of the file. At this point, removing the USB flash drive will destroy your backup data. Wait patiently for a while, and the backup will be completed.
5. When we open the USB flash drive, we will see the following folders. Among them, the xml file in the configuration is the layout management of backup data. We don't need to understand this part. All our backup data are stored in the date folder, and we can read the files inside, but it is very troublesome to be idle. We can retrieve backup data by restoring personal files in the file history.
6. Click Restore Personal File in the left column, and you will see an interface that can be selected from left to right. Every time we make changes to the files in the library, the system will automatically update the data in it according to the default time frequency. Four quarters means that I have made four changes to the file, and every time the data is saved. If we want to restore any data, we will restore the file at that time by clicking the green button.
7. Select a time period here to recover data.
8. If a large number of files in the data have not been modified, the system will skip this part. I thought it would take a lot of time to complete the recovery, but I skipped these projects and finished them soon.
9. In the advanced settings, you can change the frequency of saving files in the system. The default value is one hour. Of course, if you need to update now, you can also update it manually. You can also change the size of the offline cache, save the version, and select the default settings.
In short, file history can not only back up data, but also have the function of a time machine. We can choose a certain period of data to recover, which is very similar to many mobile phone address book assistants now. It is very convenient to select data for recovery in a certain period of time.
The above is the introduction of how to use the file history of win8 system to restore some mistakenly deleted files. The operation method is very simple, I hope I can help you.
