A couple of days ago I had a problem with an Exchange Server running out of space. I controlled database and logfile partitions and could not detect anything suspicious.

After some researches I figured out Volume Shadow Copies require much space because a backup job didn’t finish succesful and leave the VSS data on disk.

In my case vssadmin deleteshadows didn’t work, too. After some investigation I found a way to delete the Shadow Copies with the command line for WMI – WMIC

In summary you have to do the following

  • Start an elevated commandline window
  • Type in wmic and press enter
  • wmic:root\cli is shown
  • Type in shadowcopy which will list the current shadow copies
  • Type in shadowcopy delete and confirm to delete the copies one after the other
  • To leave the WMI commandline type exit
