So I have more or less repaired my backups now. Before I upgrade again there is one problem left: One big backup jobs keep checking every single file which takes ages for the backup to complete. I don’t understand why?
What I did is first I repaired the database, then run a first and after that a second backup job. With every of my 10 or so backups the repairing took a moment, then the first run somehow checked all the files which also took a lot longer than normal - but then from the second run on it would be very quick if there were no changes, even 1TB would finish in just a handful of minutes. This one big job though (2TB) continues behaving like the first run again and again. (No, of course I have not set any options such as full-block-verification or full-remote-verification.) I run it 3 times already but it continues to take almost 2 days for a single run with no changes…
Any suggestions how to fix this? Or just delete and start from scratch?
