Brand new to Server 2012 R2 Essentials so please forgive my lack of knowledge.<o:p></o:p>

In installing a RAID 5 array consisting of 5 drives each at 5TB I found that the
backup service will not initiate. When I try to configure backup of 'C' drive
consisting of OS only and 'D' RAID array consisting of all 'Shared Folders' I
get the following error message "Cannot complete the Set up Server Backup
Wizard". The size of the array is 17.3TB NTFS and I have it backing up to a
16.2TB NTFS pool created using the servers 'Storage Pool'. Currently there is no
data on any server folders, totally blank. Note: the RAID 5 array was created
using Intel RST off of the C226 chip on my server motherboard. <o:p></o:p>

In checking the RAID array using the Servers check disk it comes back with it being OK. It
appears to be working perfectly. I tested the backup pool when the server
folders were located on the primary drive SSD drive which is used purely for
the OS but wanted to test the backup process before offloading the shared folders
to the RAID array. This process worked perfectly.<o:p></o:p>

Am I missing something or failed to complete a setup? Literally I installed the OS,
added one client computer via the connector, created the drive pool and
then tested. Then created the RAID array.....which took 9 days to initialize
and then moved the shared folders to the array and then tried to test the backup.
That's when the error message started to occur. <o:p></o:p>

Thank you<o:p></o:p>
