I am trying SSR 2013 and I ran into some issues.
I am running a Windows 2012 server essentials machine with an LSI 9270 RAID card. The Card has 2 mirrored virtual raid drives setup, one for system the other for data. Both were GPT disks
So I installed SSR 2013 trial and at first everything worked fine, I was able to choose and backup my system drive and data drive. The next day I noticed that the data drive was listed as unavailable under the advanced-disks and if i tried to define a new backup I was not able to choose it from the list.
I searched online and found that if SSR finds any inconsistency with the GUI partition table info then it marks the disk as unavailable, I ran the utility partinfo.exe and noticed that there were warnings regarding the disk partition of said disk the warnings were:
WARNING: Backup GPT Header had the following problem(s):
WARNING: GPT Header Check Sum is invalid.
WARNIG: GPT Partition Array Check Sum is Invalid.
I ran chkdsk and other tools and none could find anything wrong with the disk or partition that partinfo.exe found. I read that a way to reset the partition info was to shrink the volume so I did that and it worked. After shrinking the partition 10mb for example then the program would recognize the disk again and I was able to run the backup once but after some time the program would again label the disk as unavailable and I would not be able to back it up.
I proceeded then to move all data from the disk manually to a backup disk and erased the virtual RAID drive and reset a new one in its place. I re-formated the disk, re-installed SSR, copied some data back to it but SSR had te same problem and the disk would show as unavailable again.
I wanted to isolate the problem so I converted the disk to MBR disk since its only 2tb and then found that the problem was "solved" after that it works fine and the disk is never shown as unavailable.
The system disk is also a "virtual" RAID 1 formatted as GPT and never gave me any trouble, just the second RAID 1 disk.
So I am just wondering if there is some explanation for this type of behaviour and what could I do to solve it (other than switching to MBR disks) it is important to clear this up in order to invest in SSR 2013 since otherwise I will need to choose a different solution.
Thank you.
