The disk is not full. I changed the backup time from 0:00 to another, and the copy did not happen. It was necessary to wait a day, and it worked. Is it somewhere in the task of the server itself worth the time to copy?
When you change the backup time, then the next backup will always be executed at the original time and the backup after that will use the new time as the next backup timepoint is always created when a backup runs.
