MySQL does have built-in measures to prevent this kind of disaster! They should have enabled binary logging and use that to make low impact backups. They also could have used replication (also built in) to avoid all these problems and have a hot backup.

The only reason they retained the 'Gold Support Service' is because their own database administrators obviously had no idea what they were doing or how to use the software correctly.

There are always companies that will make use of commercial support for FOSS but MySQL will probably never make any money from me.
