SBS2008 Backup to QNAP NAS Drive via iSCSI; Rotating disks?
Posted on 2011-02-13
We are using the QNAP TS-239 Pro II NAS unit as a backup target using iSCSI. I inserted the Week1 hard drive, into the NAS unit, configured iSCSI on the QNAP, and created a LUN on the hard drive that spans the entire disk. Next, I inserted Week2, and do exactly the same thing. In SBS, I connect to the hard drive with the initiator and add the drive as a backup target. I repeat this process for the second hard drive... This process has worked very well for a few years, but, sadly and suddenly, I am experiencing issues on the QNAP in our office that makes me think that it is not really designed to be used as I am using it. SBS connects to it, but the hard drive is not visible. I look at the QNAP iSCSI info, and it shows that the LUN has an "Error" state, which I cannot figure out how to clear. Has anyone configured this kind of backup solution? If so, what NAS units do you think work very well in the scenario that I have described where you want to rotate disks? I am going to be contacting QNAP this week and will post what I learn from them. Of course, we don't want to spend tons of money on the NAS unit as we are an SMB.
Thanks for your suggestions,
P.S. We are using the second bay for backing up our VMware virtual machines, and it works great!
