Hi together, actually i only do full-backup's of my virtual machines. I use the for the backup the "old" strategy: - virsh snapshot-create-as $vmname overlay --disk-only --atomic --no-metadata --quiesce - copy the qcow2 image file - virsh blockcommit $vmname $device --active --wait --pivot - the guest agent in the VM got's an 2 seconds freeze/thaw intervall Now i want to switch to the new strategy with "backup-begin". - virsh backup-begin $vmname - the guest agent does not got an freez/thaw signal As the guest agent got's no signal, is the backup over "backup-begin" still consistent ? Or do i have to be consistent to send an virsh domfsfreeze $vmname before starting the backup and an virsh domfsthaw $vmname it it is finished ? If so, the time intervall between freeze/thaw would be on an huge disk much more then 2 secords. So, is the old method currently still the better way, if only doing full-backup's ? best regards, Michael
