Troubleshoot backup management via Percona Monitoring and Management

If you are facing issues with physical backups and restores via PMM, follow these troubleshooting steps:

  1. Ensure that the user running the pmm process has sufficient permissions within PBM. You can find detailed instructions in the PMM documentation .
  2. Make sure you have specified the user from step 1 in the MongoDB connection URI string for pbm-agent processes.
  3. Confirm that the system user who runs the pbm-agent process (by default, mongod) has the read / write access to both the MongoDB dbpath and the backup storage location.
  4. Examine the systemd restart policy for the user mentioned in step 4. Ensure it is not set to always or on-success. During physical restores, the database must not be automatically restarted as this is controlled by the pbm-agent.
