Hey,
I'm sorry to hear of your situation.
If you look over your post history asking similar questions, you have been pretty explicitly advised you should be taking regular backups, both due to issues with ITFlow and unforseen Software/OS/Hardware issues. I think the restoration process has been outlined fairly well too, but we did recently add the ability to export/import a full zip as of the latest release.
What exactly is this backup you have from March?
How exactly is this VM corrupted?
