Win8 system uses file history to back up important files.

You may not know that the file history function is turned off by default. Click Start to open it. You need to select the drive for the first time. You can select an external drive (mobile hard disk or USB flash drive). And the network location, the network location needs to establish a family group, and then back up the files to the hard disk of other members of the family group. Since the author has not established a family group, only the relevant functions of the U disk are displayed here, and the use of the network is similar.
It is a pity that the file history does not support the active selection of the drive folder, only supports linking to the library, but in fact, we can associate the files that need to be backed up to the library. The default is to back up the files in all the libraries. If we don't need to back up a lot of useless HD video or music files, you can select unwanted library files in the exclude folder, and remove a lot of unimportant video files.
First step, click to run immediately, you can back up the library file, the speed depends on the size of the file in your library, the first time is slow, now the file history is backing up your file copy, this time shift In addition to the U disk, it will destroy your backup data, wait patiently for a while, it will be backed up.
The second step, when we open the U disk, we will see the following folder. The xml file in Configuration is the layout management of the backup data. We don't need to understand this part. The data we backed up is saved in the Date folder. We can read the file in it, but it is very troublesome, we can Retrieve the backed up data by restoring personal files in the file history.
The third step, click on the restore personal file in the left column, you will see an interface that can be selected from left to right. Every time we change the files in the library, the system will automatically update the data in the default time frequency. 4/4 means that I have made 4 changes to the file. Every time the data is saved, if we want to restore any of the data, click the green button to restore the file; if it is in the data A large number of files were not changed, and the system skipped this part. I thought it would take a lot of time to complete the recovery. I skipped these items and it was completed very quickly.
The fourth step, in the advanced settings can change the frequency of the system save file, the default is one hour, of course, if we need to update now, you can also manually update. You can also change the size of the offline cache, the saved version, and select the default settings.
