Hyper-V Backup, Permission denied reading a fuse mount point

Post by robnewton » 2019/06/17 02:48:25

Hello,

I have a Centos 7.6 VM running on Hyper-V.

Attempted backups of the VM by hyper-v are failing with this filesystem read permission error:

Hyper-V VSS: FREEZE of /run/user/1553/doc failed; error:13 Permission denied

The Hyper-V VSS daemon runs as root, but there are some parts of the filesystem that even root cannot access, such as fuse mount points. Some of these are only readable by the user that creates them, not root. So it appears that it fails trying to read a fuse mount point in /run/user, and then aborts the backup.

Is there some way to exclude certain parts of the filesystem from the backup? The VSS daemon should not be looking at fuse mount points anyway should it? Is it a bug?

Many thanks,
Rob

Since you don't want to back up /run at all I think you've been saved some work.

True, but the backup is aborting, nothing is backed up.

So exclude /run, you don't want it or need it and it's useless anyway.
