Well, I had no expectations here, but I have 10TB stuck in a download and Google would not authenticate because you have to use the non-SSL connection to the DSM. I’m happy to report that after a week of “relink” in progress, it actually worked! I can now see all my old backups.
All you have to do is just click on the same directory and folder when you try the relink, it reads the .hbk files up on the cloud service and then recovers the entire backup. How cool is that!
