sitecore SIM - backup installation as restore point

After doing a fresh install of a sitecore site through the sitecore instance manager (SIM) including packages like Sitecore PowerShell Extensions and other stuff you want to have installed you can make a backup (right-click on your site > Backup) as a fresh restore point in case things get terribly wrong. 

Note that the backups are made in the folder C:\websites\mysite.dev.local\Backups.

Install the latest version of SIM from http://dl.sitecore.net/updater/sim/.
