The real-time schedule in the backup wizard that we have is a near real-time backup.
As of now runs every minute and pushes data to the cloud. It will never complete because the idea of it is to have its schedule to run every minute and upload changes to the cloud.
In other words, it pushes data, wait for 1 minute, collecting changes on the filesystem in the meantime and transfers the next batch of files.
Can you send a screenshot saying it will complete in 3 years? This is something unexpected, at least for me.
