Veeam unexpected "health check" for backup copy job

In Veeam we have a backup copy job for creating offsite backups on usb disks.

Now I see that Veeam performs a health check on the usb disk.

I can't find any possibility to configure health check for copy jobs (Only for regular backup jobs as described here: Veeam documentation)

The windows system eventlog does not show any errors for the disk.

Edit
There is no unexpected cancelation in the history of the backup copy jobs.

Questions:

• May the health check indicate that Veeam found an error on the usb disk?
• Can health checks be configured for backup copy jobs?
