[Web Deploy] Automatic backup not created properly when deploying from VS 2015

Hi,

I try to make automatic backup works when I deploy a website from Visual Studio 2015 with the publish wizard.

My problem is when I deploy a new version of a website from IIS Manager/WebDeploy everything works fine with automatic backup (I mean, the backup is fully created as expected). However, when I deploy the same website from VS 2015 with <EnableMSDeployBackup>True</EnableMSDeployBackup> in my pubxml file), the backup is not created properly. I only got a ZIP file of 64 KB  with two file in it : archive.xml and systemInfo.xml.

I cannot figured out what I am missing to make it works…

Thanks for your help!

Best,
Niniel
