i am in charge of setting up a DR solution for my office, we are wunning a windows 2003 standard domain controller , a exchange 2007 server, an application server and a file server. the data on the file server is large but does not change very frequently, we want to be able to recover from a major disaster. the plan is to have a DR site at a colocation facility.
we can setup a site to site vpn tunnel and setup a domain controller and global catalog server on the DR site, we can also copy all the data on the file server and run rsync everynight to keep the files updated, but my problem comes when looking for a solution for exchange and sql, my exchange information store database file is about 20 gigs and SQL is 5 gigs. is not something that i want or can move over the tunnel everynight.
i been looking at solutions like doubletake and inmage, can you guys provide me with suggestions, pros and cons about those products or any other products that may do the job.
lately i have also been considering, migrating my exchange server to a VM, using VMXi (wich by the way is free now) and use the VMWARE ESXreplicator or a product from Vizioncore call vreplicator, but i am not sure if those products will move the complete VM file or would only sync the changes. i would appreciate any comments.
It does require that you have two sites, and the exact same equipment at either end to replicate and of course bandwidth.
