Compress image file to Yes delete the image after Creation

Hi,

I'm running the latest version of Webmin/Cloudmin Pro. If I choose to create a System Image (from Create Image) of a server and select "Compress image file? Yes" (the default) the system create and compress the image but after the compression the image is deleted (the messages is like this:

Compress image ..... (I can see it on /var/webmin/server-manager/) Delete compressed image ... (and the image is deleted)

If I choose Compress image file? No the Create Image works fine but with big images this is a very big problem (in term of used space).

Thanks
