It is very necessary to back up important data, so as to avoid many unnecessary troubles. Of course, I believe many of my friends feel that it is too much trouble to do backups regularly. It doesn't matter, we use WinRAR to automatically back up data. The specific method is as follows: Backup principle: automatic backup is realized by combining winrar's automatic compression file and system task plan. First, create a configuration file to start "resource manager", enter the E:\\5uhezu folder. Select and right-click all files, select “WinRAR→Add to tarball", open “compress package name and parameters” window, click “backup& rdquo; tab, check “by mask to generate compressed file The name & rdquo; check box, the yyyymmddhhmmss in the following text box respectively represent the year, month, day, hour, minute, second, can be selected according to needs, for example, we set the saved file name to. Year, month, day, hour, change it to yyyy-mm-dd-hh. Middle - can not be added. Plus just look at the convenience. . Then click on the “General” tab. And click the “Browse” button to save the file to the E:\\5uhezubak folder. Then, click the “Configure” button, select “Save current configuration as new configuration", enter the backup scheme name in “configuration name", such as “geminbak”, and select “Save archive filename ” and “Save selected file names & rdquo; and “ checkboxes on the desktop to create shortcuts & rdquo;. Click the “OK" button to return to “Save archive filename and parameters" window, press “OK” button to back up the file. The following is the above diagram: Second, the regular backup click & ldquo; start & rarr; set & rarr; control panel & rarr; mission plan & rdquo;. Next, drag and drop the “geminbak” shortcut on the desktop to the "Task Schedule" window. Then double-click the <quo;geminbak” icon to set its properties. Click the “Schedule” tab, click on the “Task Schedule” drop-down list box, and select “ Weekly”, and “Start Time” to set your own time. Click the “Settings" tab, uncheck “ under "Power Management", if the computer is running with a battery, do not start the task. After the above settings, the computer will automatically back up all the files under E:\\5uhezu to the E:\\5uhezubak\\ folder, and the date and time of the backup will be the file name, such as gemin20110421222222. Rar, gemin20110422222222.rar and so on. Note: Enter the password of the computer user after confirming. Remember that if the user does not have a password, be sure to set a password in the user management, otherwise it will not be automatically backed up. The following is an illustration: Tip: If you want to back up data when the computer is idle, you can click on the “Task Schedule” drop-down list box and select “When Idle”, when “The computer is idle for more than xx minutes” Change the time to 10 minutes. After completing the above settings, press the “OK" button, and then enter the system administrator password in the window that opens to exit the settings window. In this way, when there is no operation after 10 minutes, the computer will automatically back up the data. Automatic backup when the system starts: Click the “Task Schedule” drop-down list box and select “When the system starts”, the system will automatically back up the data when it starts. Shut down after the backup is complete: If you are off work at 5 o'clock, you can click the “Advanced” tab when you create the WinRAR configuration file, and then select the “Turn off the computer power after completing the operation” checkbox. Then set the task plan to back up the data at 5 o'clock, so that after the data is backed up, the computer will automatically shut down.
