Will dynamic disk restore to RAID 1 volume?

Thread needs solution

I have attempted and failed to create a software mirrored array. I had to convert my OS disk to a dynamic disk to make this attempt. The attempt failed due to the Windows OS being unable to determine physical sector size. Consequently I have decided to create a hardware RAID array instead. Since I will lose all data when I create the array, I need to create a bare metal backup of my OS first. When I tried to do that Acronis said it doesn't support dynamic disks! Thanks a lot Acronis!

So it seems in order to backup my OS I need a new backup product. My question is if I get the Acronis upgrade and use that to create my bare metal backup, will it restore to a RAID 1 drive?

I need an answer to this fairly urgently.

Thanks

Did you attempt to clone this disk instead of a as you describe a bare metal backup by chance? If you are attempting to perform a bare metal backup as you describe from the installed TI app on your machine it is not supported. Having said that you can perform this operation from the bootable media disk. Maybe that will help

Hi Bob, Thanks for the reply. I did try from the boot disk, but it went straight to the dynamic disk error message, then when I OK'd that, it rebooted.

I am resigned to having to buy the Pro version so long as it will restore to an empty hardware RAID mirror from a dynamic disk backup. Will it do that?

What version are you using now? Trial?

Additionally, your backup options mode needs to set to partition mode and not whole disk mode to backup dynamic disks. If you did not choose to perform the backup in partition mode then that's why it is failing.

I am using Acronis True Image Home. It won't deal with dynamic disks at all. I never get a chance to even try a backup either using disk or partition mode since as soon as it starts to detect disks it provides the dynamic disks error message then shuts itself down and reboots.

Please stop providing answers to questions I didn't ask.

All I want to know is if I buy the pro version and backup my dynamic disk, will it restore onto an empty RAID 1 array?

Yes.

The answer to your question is yes with some conditions. The Premium version will support dynamic disks. The question is will the Linux based Recovery Media have drivers to support your particular Raid array. You won't be able to answer that question until you boot the Recovery Media with your Raid array in place. If TI sees your array as one disk, you are all set. If it sees two separate disks, you can't proceed. In that case, you will need to make a WinPE Recovery Media. The Premium version will allow you to do this. WinPE has support for most, but not all hardware. If it doesn't see your array as one disk, you can add the Raid drivers to the WinPE disk and it will work.
