@DukeNukemSo all I need to do is keep a backup of my folder and copy the cards before rebuilding.
Yes, that is correct.
You could also as for redundancy, compressing the whole specific Folder of ***** o Fee
(which contains all the .vghd Files) and make a Backup, also for all other Models
which are not more available in the Store, and Upload it
to your
personal/private Cloud Storage (Dropbox or Google Drive for Example).
So for the case your physical Backupdrive has a failure, you can Download the Folders
again and again from your Cloud Storage, as long as you have an active Account there of course.
Or you can use a paid Cloud Storage to increase Data Security.
