Queries on Copying VMware on an External Drive
Presently, we are using ESXi 4.1.0 and we are planning to buy a new external drive which can be used to copy the VMware's if any maintenance is required. For upgrading, we need to reinstall the ESXi after creating the data stores and copy the data over VMware which had already backed up to an external drive. The drive will be useful when doing the maintenance for single VM. And still we need to back up the Virtual Machine Disk (VMDK) before the maintenance on host. Please clarify my 2 questions below:
a. The details I have specified above will work for recovery with the installation?
b. Which one will be the best external drive from USB and iSCSI to do this?
I am thinking about the Seagate BlackArmor which is claiming to VMware certified and also supporting the iSCSI. I am waiting for the inputs. Please help me to get out of this problem. I will thankful for all help.
