Follow up question on this and sorry if this is a dumb question but..

In https://openvz.org/Ploop/Backup#Image-based_backup

vzctl snapshot $CTID --id $ID --skip-suspend --skip-config
cp $VE_PRIVATE/root.hdd/* $BACKUPPATH/

Should we be including the snapshot in the backup itself? Wouldn't copying the snapshot be copying where any new data is taking place which is possibly why we are seeing the corruption? Maybe I'm not understand the snapshot but if we instead did..

vzctl snapshot $CTID --id $ID --skip-suspend --skip-config
tar -cvf backup.tar --exclude='./dump' --exclude='./root.hdd/root.hdd.*' $VE_PRIVATE/root.hdd/

then deleted the snapshot.

Wouldn't this method 'freeze' root.hdd basically ensuring no data will change within it while we backup the image to ensure the db integrity?
