Automatic backup every xx minutes	If this option is selected, you can set the time interval at which Vissim will save your Vissimnetwork to the backup copies. Default value: 15 minutes, value range: 1 minute to 120 minutes. Vissim then regularly saves and overwrites the following backup copies of the <name>.inpxnetwork file if you make any changes to the Vissimnetwork: <Name>.inpx.inps <Name>.layx.lays Save manually on a regular basis if you do not select this option and you are editing the Vissimnetwork.
Common folder for backup copy	If this option is selected, you can choose a directory/folder where Vissim will store the backup copies of different Vissimnetwork files. The directory you chose is selected by default the next time you open Vissim .  If this option is not selected, Vissim saves the backup copy to the working directory of the network file.
