Backup Copy Job will search for the latest restore point for a VM and use it to process data. The process is well described athttps://helpcenter.veeam.com/docs/backu ... tml?ver=95

When you configured it to run daily, the latest restore point got copied over as expected, then it declares "already processed this VM Copy today".
If you set the interval to more frequent one, lets say hourly, it should have found the restore point. I'd recommend to check the logs for both, primary and Copy backup jobs and correlate the status of files and timestamps and see if the files weren't in consumable state.
