Some questions about backup, verification recovery and recovery

I am backing up and restoring my Qubes, but there are some problems. I would like to ask for advice.

  1. I am using the backup GUI interface, but when the backup progress bar reaches 100%, finish is always gray, but I use the ps aux command to show that there are no processes in the background. Is the backup complete?

  2. When I went to verify the backup, the progress bar kept moving, but no progress value was displayed. I went to ps aux to display the CPU percentage, but after 1-2 hours, I did not see any vm being successfully verified. They were all displayed as being verified. Is this normal? How to monitor the verification and backup process commands well?

By the way, I forgot to mention it. Although the finish button is always gray after backing up 100%, I see that the compressed package in my mobile hard drive is indeed very large.

The latest news: It only shows that the verification is successful, and a directory connected to the mobile hard disk pops up, but the finish is still gray. Is it probably a bug?
