I'd like to know how did you configure your backup server as a VM ?
my idea is to utilize the local VMFS3 datastore on my 3x ESXi servers,
by installing the 3rd party application (like Veeam Backup 5 or Backup Exec 2010) into Windows Server 2008 R2 VM
equipped with very big hard drive size (8 GB OS + 1 TB data partition VMDK) on each of the local datastore to backup the VM inside the SAN.
What I've got:
VMware vSphere 4 Essential - ESXi 4.0 (no hot add)
Dell Power Edge 2950 with 2.5 TB multiple VMFS3 extent on top of - RAID 5 (6x 500GB SATAII 7200rpm)
Dell MD3000i iSCSI SAN over Gigabit Ethernet
The Windows Server 2008 R2 VM configuration:
2x CPU @ 2.33 GHz
4 GB RAM
VMXNet3 NIC --> for better connectivity of the backup between the local ESXi datastore and the iSCSI-SAN datastore.
Here is the reason I'm doing this is that:
1. I don't have the extra NIC to connect my physical server into the iSCSI SAN switch, therefore i can't use -SAN backup mode.
2. I only use the lowest VMware license available which doesn't support hardware Hot-add feature.
Would this be optimal configuration ?
Any kind of help and suggestion to implement VM backup as VM would be greatly appreciated.
