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
