Hoping for some help as I keep getting this error every time I try to edit or even backup my database. Hoping for suggestions--thank you in advance!

calibre, version 4.4.0

Happened to me about two weeks ago. Restore failed. I had to create a new location and "add books" from the old location. Now I upload to a cloud backup.
