asked on
disaster recovery plan
I need to build a disaster recovery (DR) system for my branch office to be
located in our datacenter(Branch office has many virtual machines). I have Sun J4400 (6 TB) which is direct attached iscsi.
I was planning to install VMware vSphere on the server here in the corporate office. The question I have: what is the best way to copy the VMs and its data from the live system to the DR system without disturbing the live systems.
My original plan was (and still) is to have the DR system connected with direct T1 line between branch office and the datacenter in corp office, this prove to be expensive so we are discussing the idea of doing the sync using the public internet, ( looking to the volume of data need to be synced every night it not much and it can be downloaded to the remote site over night) The other problem, as I know we used Quantum to be the local storage, as recommended by the company who did the original design, I was not involved in this, the Quantum has the ability to do remote backup and sync with another Quantum box on the other remote end (also data domain offer the same function).
Now we are looking for different solution which can do the same, we want a way to upload the incremental daily changes from the quantum box at branch office to the corp site, then do restore to sync the changes to the VM machines.
I hope this will make it little clearer, please do not hesitate to ask again if this no clear.
What third part SW you are suggesting?
Thanks in advance

@nappy_d:
Vmware SRM does not do replication and is not a solution.
@Siddaraju:
vReplicator from vizioncore is a soution that will do what you describe and it can be combined with a storage solution of your choice.

As an alternative, you could purchase a SAN (such as NetApp) that will easily integrate with the vmware environment and provide built-in replication and DR between storage boxes.
Actually, it is a solution when used with thrid party tools for replication.
What speed pipe do you have to your public pipe? You have various backup/replcation options: Vreplicator, datadomain, etc... but depending on the change rate... you may run into problems even over a dedicated T1. You mentioned that you had a lot of virtual machines.
Are you looking for a backup or a replication solution to constitute your DR strategy? These are very different strategies and each have their pros/cons.

Even though his company has suspended their plan, this information provided is still valuable and can be referenced at a later date :)
