Hmmm. I'm not so sure that *no* backup is needed. Even if the VMs are based on a template, they are probably customized at least somewhat, so you'll probably want backups if you want to restore from a failure quickly.

(My goal for backup/recovery is to expend as close as possible to *no* thought at recovery time. In this case, you would not want to be caught at recovery time scratching your head and wondering what sort of customizations need to be applied to your "template" in order to make the database open.)

Depending on the VM technology, you might be able to make snapshots (exclude the disks managed by ASM, if you can). If the VM snapshot technology is really good, these might be very efficient on storage and other resources. Failing that, you should think probably about backing up the Linux filesystems exactly the same way you would a physical server.

Yeah, backing up the filesystems on your VMs is going to consume some storage.

Yeah, a lot of the data you're backing up is probably cloned from a template, so the backup might SEEM wasteful.

But when those backups save you maybe 1 or 2 hours of effort (per virtual machine) at recovery time, you're likely to find it was worthwhile.
