My vps has the option to create an online snapshot. However there is a warning regarding possible data corruption. I asked the ISP and they replied that this is primarily a concern for the mysql databases and they suggested shutting down MySQL temporarily. Obviously my websites will not work with MySQL disabled so that does not add anything compared to the offline snapshot.
How do you guys deal with this? Do you somehow lock MySQL? Or do you dump all databases and import them after backup? If so what would be a good command to do this?
