My boss doesn't want to spring for a proper backup application. He wants to do a monthly backup of a vm guest by copying the vm guest files to a file server and then have them overwrite once a month. However, I'm not sure which files to grab. Do I have to grab all the files in the folder for the guest on the datastore? Or are their specific files I can grab (.vdmk, etc.). I have not found an article that explains it simply. Any help would be appreciated.
Another not, I assume, to restore the files, I just copy them back to the guest folder and power up the vm thus it's restore from the last copy?
