PMM cannot restore MySQL backup data

Hello, first, allow me to outline my current service setup. I have created the following containers on the same server using Docker: pmm-server, pmm-client, MySQL (8.0.35), and minio-server. After setting up these services, I resolved several issues. I added my S3 storage location for MySQL backups via the Storage Locations section in the web interface. Subsequent backups of MySQL succeeded, but I encountered problems during restoration. Since my pmm and MySQL containers reside in separate containers, I mounted the MySQL Docker data volume as read-only to pmm-client:deep_db_db-data:/var/lib/pmm_mysql_backup:ro. I avoided mounting directly to /var/lib/mysql because clicking restore triggered client logs indicating the path was in use. So I changed the path and created a symbolic link between /var/lib/pmm_mysql and /var/lib/pmm_mysql_backup. When I clicked restore, the /var/lib/mysql directory within the pmm client was renamed, then a new /var/lib/mysql directory was generated. I wonder if, when deploying the PMM client via containers for recovery, the operation only restores /var/lib/mysql within the client container itself. It doesn’t synchronize the restored files to the MySQL data volume. This likely explains why my data wasn’t successfully recovered after restarting the database. I’d like to know if the current PMM supports full backup and restore workflows for MySQL. If so, I haven’t found documentation explaining this capability. If container isolation is mandatory for backup/restore, how should I address this issue?
