I made a prototype of the SharePoint 2010 site in via the VirtualBox machine. I have successfully made a backup of the entire farm (all elements are backuped without errors).
After that I have restored the backup on another VirtualBox snapshot and on a real machine without errors (all elements were restored successfully).
However, when browsing some SubSites and their page, I receive the following error:
Server Error in ‘/’ Application.

Some resource files imported via the SharePoint designer are unavailable as well.
This issue is caused by the fact that the v4.master Master Page of a specific SubSite is corrupted (and was missing after restoration… for some reason).
When opening a restored SubSite in the SharePoint Designer, the corresponding Design Time error message occurs.
