Hi,

I’m making some test to backup my full machine to an external drive (I know full machine backup are at risk to no being coherent).

So I run kopia from root user, but my regular user has a FUSEFS for keybase mounted under /home/jfburdet/keybase

The directory /home/jfburdet/keybase is readable by the user, but somehow (FUSE stuff I believe), root can not read it.

So the end result, event with trying a lot of exclude combination (starting with home/jfburdet/keybase) without success, is kopia making a snapshot for /, but when exploring the snapshot with the UI, /home/jfburdet is completely missing from the snapshot.

If I switch off the keybase file system service (kbfs) service, the backup now runs fine, and /home/jfburdet (and its content) are now part of the snapshot.

I don’t know if it is a bug, but any input to help me run the backup with the service running would be welcome.

(Sorry it this looks confusing, english is not my main language)
