Yes, I'm planning to add the suggested parameters as well. Will also try out the mt-st command.
I am pretty sure that the error occurred due to the mount and unmount scripts that I included in each run of the backup job, it would be interesting to see if the error still appear with the new config. Actually I don't even need to use the scripts anymore, but maybe I'll just make a test for the fun of it. Will let you know on how it goes. Thanks a lot for your help and advice.
