Hi,
I am having the same issue since some days. I read some posts, tried a repair and even a recreate of the database. Nothing helped, luckily the other backup job runs smoothly, which is the most important one.
Therefor I am offering my help to get debug logs or any information needed to get an idea why this is happening. This, and other threads, are quite long and offer lots of ideas and tasks to do, I am asking someone for help to guide me in what information is really needed to get this fixed.
The backup I am talking about holds no personal nor valuable data, and it is only 16GB in size, which makes recreating it now a big deal.
If someone could help me gathering the right information and placing it where it is needed - I am the one to do the work at the end.
Thanks
