Re: VMWARE Snapshots to backup Oracle

Why would enabling backup mode, mean that backups of online redo logs are not required?

If you do a snapshot of the database while online, by implication the backup will only be useful after recovery, and the redo logs would be vital to guarantee the recovery?

Perhaps, I've missed something, please correct me if I'm wrong.
