I’m glad it works for you guys, but it definitely doesn’t for me.

I don’t think it’s a particular failing of Avast! per se, more like some SATA overload - but it only occurs with backup + shadow copy + avast. I think there’s a strong argument that says I might have to troubleshoot the SATA bus drivers etc. but in the meantime, I think it’s a reasonable request to see if Avast! can be shut off during backups - even if you didn’t have my issues, it would be a performance concern.

If I manage to shut off Avast! during the flailing backup, things suddenly snap to and work great. Computer is pretty locked during that process so it can be trying…
