I am pondering this same issue with my Oracle DB servers. We are running Red Hat VMs and using RMAN for Oracle backups.I've been considering using the Independent disk mode on separate virtual disks for database files and logs. Flagging virtual disks as independent and persistent would avoid snapshots being applied to those critical data areas. Then in Veeam backup, you can choose which SCSI disks you would like to backup (OS). Finally, if you need to restore, you can restore the OS of the VM first then restore the DB files from the RMAN backups??? Thoughts?
