Looking at deploying Vmware vSphere with SBS 2011 & 2008 R2 running RDS. I have a pool of 1 TB usb drives & a 3 TB NAS (no iscsi target though) We've hit the budget so we are currently running the free vSphere or at a push will upgrade to Essentials.
I was planning on using USB passthrough to the SBS 2011 and backup using backup assist from the SBS Server straight to the USB Device. Same for the RDS Server. The RDS server will only get backed up once a week as it contains no data.
Is this an acceptable backup considering our budget retriction? My obvious concern is it's all good while the host works but how to I actually perform a baremetal recovery if the host dies. I have the USB drive with the SBS 2011 backups but how is the host actually prepaired etc to accept the backup?
