Dremio volume folder backup

1

Hi,
My Dremio run in the docker and store data (/opt/dremio) in volume.
Can I simple backup volume data with “cp -ar” on the running container and then create a new container and put data in the new volume?

I did that, but I got next error in the logs:

@alexdi

It would be better to copy the “db” folder when Dremio is down. But the error you see is unrelated as it clearly says that the unix user you are trying to use to start Dremio does not match with the unix user that owns the “db” folder
