Shrinking can also be made with the normal cp from linux:<br><br>cp --sparse=always<br><br>This will create usually files smaller then the original even.<br><br>But maybe this can be fixed from the source. Exporting some images that have 10s/100s of gigabytes but only use a few gb is time and space consuming with no benefits.<br>

What I think was on the head of who implemented this is that you export a VM to a NAS that has normally Teras of space, so it is more compatible to save it in raw format. My 2 cents :-)<br>

Hi all,<br><br>I see that exporting a VM with ThinProvisioning will make an image with the full disk size, instead of the currently used size: <br>- VM has a 20GB disk<br>- installed OS is taking 1.3GB<br>- exported disk is taking 20GB<br>
<br>Is this mandatory? Couldn't the export make a file with the same size, also sparse? It seems it only does a copy of the folder and the normal linux cp can make a sparse copy.<br><br>thank you,<br>Cristian Falcas<br>
