On one of my server, I tried to mount s3 repository to local for reviewing backup files via kopia.  
The backup is not started on this server.  
But I noticed the memory and bandwidth usage is abnormally high when the repository is mounted, and after I unmont the repository, the usage dropped immediately. I don’t understand why.

Any hints for this?
