Alexander,

Thanks for the reply. Actually, for MY situation, we are in that awkward "straddling the fence" position where we are ready to use the New Backup Format but the server drives filled up while we are using the legacy, File-Level format. (BEFORE my time) And our founder also recently re-arranged the structure of files/folders, so an entire back-up was forced. Throw in some storms, atmospheric rivers, barometric bombs, and it's been challenging. We are struggling with a 25TB volume that has been backing up (legacy, File-Level) since March 6 with some blackout and Internet interruptions, but currently shows 42% complete. IF we can trust that number, we might be looking at a few weeks before we can move forward.

I've recently forwarded some Logs and trying to schedule time with Dylan for a real-time look at what we can measure to make the decision between "let the old Plan complete" versus "switch to a new plan by starting over" which is where we are stuck. It's just that straddling becomes painful over time.

Suggestions/thoughts/recommendations are appreciated. I'm back at the office on Thursday for more troubleshooting, so keeping my fingers crossed.

Late to the party, and not to pile on, but doesn't this seem to indicate that YOU are not authorized to make back-ups of certain files - by company policies dictated by executives and enforced by the systems administrator(s)? That error message would seem to point in that direction.
This is not a back-up problem. This is a square peg into a round hole problem. If you are not allowed to keep certain files locally on an SSD, you are not allowed to back them up either, end of story IMHO.

We encountered a similar situation. Back-up was running for several days and started from zero again.
Better Error handling would be appreciated. If an Error is detected, please notify the user about the problem and display some kind of error information. We do not expect perfection, but we don't want to create another Microsoft ("Blue Screen"? nah, those don't exist....)
