Disaster Recovery only half a solution
Posted on 2012-03-22
I have a situation with a client whereby they have a Netapp/VMware solution This included a Netapp installed along with VMware a couple of HP hosts and LTO4 tape drive with Symantec and the NDMP option.
On reviewing it there is no quick DR solution in the event that the main server room with all the above is worst case destroyed.
A second netapp was an expensive option that could not be considered.
We need to be able to recover about 4 of the virtual servers very quickly in the event of the server room being destroyed.
I need help with the most cost effective solution for this.
My thoughts were to create a network link to there security office( about 7om from main building)
Use this link to connect to the Netapp switch and a new switch in the security office.
Connect a small NAS device (4GB of space) and an HP server with enough power to run the 4 key servers(install the ESX host on this) Also need a new tapedrive to connect and restore data.
This next bit I am not so sure is possible. I would like to automate the cloning of the key VM onto the new NAS device. This could happen once a week.
In the event of a distaster the latest tape data could be restored over the VMs and the systems would be up and running.
Any thoughts on the automatic cloning would be greatly appreciated
