While restoring pmm 3.4 data getting permission errors

1

Hi,

Server1 is running PMM 3.4.0, and Server2 has also been installed with PMM 3.4.0.We are attempting to restore the PMM 3.4.0 backup from Server1 onto Server2.

However, during the restoration process, we are encountering the following errors

Could you please check and let us know how we can fix it?

Hi Suman.A,

Can you provide the instructions on how you are copying the files from Server1 to Server2 so I can help you? That being said, restore methods are provided in this link: Restore PMM Server Docker container - Percona Monitoring and Management

Thanks.
