and the only thing I can think is a backup which in my case it a done with _libvirt_ as pgSQL cluster runs on Ubuntu VMs. I'm not sure what exactly _virsh backup-begin_ does to the qcow2 and as a consequence, to the the FS in the VMs, but.. it would be good to have those backups.
Any thoughts & ideas shared are much appreciated. I guess my first question would be -- if such VM backup might affect negatively pgSQL then, are there some tweaks, ways to harden pgSQL cluster internally for such scenarios?
