I’am using PMM v1.3.2, i do have a mount point /srv witch contains
/srv/consul, /srv/mysql, /srv/prometheus, /srv/update, /srv/grafana, /srv/ngix, /srv/prometheusarchived_fingerprint_to_metric.
I guess that the metrics data is stored by prometheus as levedb witch is compliant to backup over btrfs snapshots
butt on the same disk there are alos mysql data witch semms to contain the host and agent configurations, but mysql is not 100% compliant witch btrfs snapshot backup methode.
is There a documentation out there that explains what data is stored where and under what format ?
I have tried VMBackup (snapshot) but the Mysql database was not properly backuped by this process (tablespace allocation problesm) that where not recoverable even whit innodb recover mode 6.
I wondered that i did not find any information regarding reliable backup strategies for pmm server by percona, What is the official possition for backp strategie on pmm server ?
