Mouse is placed in the lower right corner ——callout super button——select settings——control panel——system & security——file history
file history function defaults to Closed, click to start, you can open it. You need to select the drive for the first time. You can choose external drive (mobile hard disk or USB flash drive) and network location. The network location needs to establish a home group, and then back up the files to other member computers of the family group. On the hard disk, since the author did not establish a family group, only the relevant functions of the U disk are displayed here, and the use of the network is similar to the ghost xp sp3.
It is a pity that the file history does not support the active selection of the drive folder, only the link 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 all the libraries. Files, if we don't need to back up a lot of useless HD video or music files, you can select unnecessary library files in the exclude folder, and remove a lot of unimportant video files.
Click to run now, you can back up the library file, the speed depends on the size of the files in your library, the first time is slow, now the file history is backing up your file copy, this time remove U disk, will destroy your backup data, patiently wait for a while, it will be backed up.
At this time we open the U disk, you 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.
Click on the left side of the restore personal file, 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.
Select a time period here to restore data.
If a large number of files in the data have not been changed, the system will skip this part, originally thought that it takes a lot of time to complete the recovery, skipped these items, and quickly completed.
In the advanced settings, you can change the frequency of saving files in the system. The default is one hour. Of course, if we need to update now, we can also update it manually. You can also change the size of the offline cache, the saved version, and select the default settings.
The total file history, not only can backup data, but also the function of the time machine, we can choose the data to recover in a certain period of time, which is similar to many mobile phone address book assistants nowadays. It is convenient to select data from a certain period of time in the past to recover.
Summary: Netizens have read the above specific method of using the backup file, do you think it is better to use it! You can also easily modify the file! Br>
