I have twoo questions: 1. How can I see the mirroring disk on the server. - I can't see even thru Disk management. 2. I am doing a backup on the external Hard drive - but I cant't see the contents and I can't even see the external hard drive thru Explorer. But I can see the external hard drive thru Disk management
This is a Server 2008 R2 forum for support on Server 2008 R2. You seem to be looking for SBS support?
That being said, you're asking about mirroring... Mirroring can also be done at a hardware level, so your OS won't show the mirroring in this case.
If you're simply backing up to a hard drive, I'd think you can see it. In disk management, do you see the drive as having a letter and being NFTS formatted?
