File ownership for backup

I guess I should add that I am trying to do this with influxdb still running, but as I understand that should not be a problem.

Also, my mount point is from an ext4 formatted drive I have auto mounted using fstab. I read a similar issue, here: Influx will not start if data directory changed - #2 by jeff
but I believe I already have my permission set correctly all the way back to the mount point:

spvirt1@spvirt1:/mnt$ ls -l
total 4
drwxrwxr-x 5 influxdb influxdb 4096 Apr 17 09:45 virt_drive
