Anyone who’s ever trashed a spreadsheet, or accidentally deleted a file, will appreciate the 'previous versions' function. However, you will only find out that this is not enabled by default when it is already too late.
You can enable previous versions by enabling shadow copies at a ‘volume’ level, Server Manager> Tools> Computer Management > Share Folders > Configure Shadow Copies > Select the Volume > Enable. It will take about 15% of your space, so make sure you have enough room.
In my case i want a copy each hour, go to Advanced Schedule Options interface, select Repeat task, and then set the frequency to every 1 hours, then Select Time, and then change the time value to 2:58 AM.
