I'm attemtpting to export a full site and receive this error
The export is disabled because of insufficient permissions in the directory 'E:\inetpub\wwwroot\Folder\CMSSiteUtils\Export\'. Please grant the account 'IIS APPPOOL\<username>' with read, write and modify permissions.
Sure it sounds easy enough to resolve, just follow the directions it gives. What I want to know is why can I export webparts, document types and about any other object without issue but cannot export the site? Why are different credentials used because of file system access?
