Guest VM Windows 2012 Storage Spaces Support?

Veeam Logoby jgrote » Mon Mar 18, 2013 11:41 pm

Hello,

We are looking at deploying a new Windows 2012 file server with deduplication enabled. We have about 8TB of data we want to protect, and with 2012 we have a new option to deploy multiple 2TB disks and link them together with Windows Storage Spaces, which is preferential to us as opposed to, say, multiple lettered drives or . I know I can back up the server fine and do full-vm protection and 2012 is listed as a supported guest for Veeam 6.5, but this is a bit more expanded circumstance.

Primarily, we want to know if Veeam guest file-level restore is supported with Windows 2012 storage spaces and deduplication in the guest. Thanks.

Specifically:
1. Will guest file indexing still work with it?
2. Can we still restore individual files using the wizard (obviously we can mount the images and get to them that way assuming Veeam is 2012)

Hi,

Deduplication is definitely supported for FLR, there are existing topics regarding that here on this forum.
However, storage spaces were not tested as a part of the latest release (aside of most basic configurations maybe).

Thanks!

jgrote,
I was actually just testing this and noticed the Veeam does not understand Storage Spaces for FLR. My E: drive (Storage Spaces volume) is missing in the backup explorer, so it looks like Veeam does not yet have FLR support for Storage Spaces.

We'd also like to use Storage Spaces as they're much easier to grow versus traditional multi-volume setups.

Gostev,
Is there any word on when Veeam will fully support Storage Spaces for FLR? I'd think it must be in development or Veeam is really behind on supporting this extremely useful new feature.

Hi Alan, basically right now "Veeam is really behind on supporting this extremely useful new feature" based on the amount of requests for this feature (which is the only measurement of true importance for us). Besides, Storage Spaces have completely different purpose: they are designed to create a redundant storage out of JBODs for hypervisor to use. They are not meant to be used from within VMs. Out of curiosity, can you share your use case for using Storage Spaces within the VM? Thanks!

Is your Veeam server running on 2012? Aside from the storage spaces issue,you would need it to see the dedupe volume.

Gostev,
I use Storage Spaces within a VM to provide a dynamic, multi-disk pool of storage for our users. By placing our fileshares inside a Storage Space, I can expand capacity on-the-fly with extra provisions for things like enhanced fault-tolerance and multiple SAN targets backing the same volume. I realize that I could technically accomplish some of these things with VMware extents or spanned disks in Windows, but Storage Spaces provides an easy way to add space and performance. In out small department, I can add to people's Windows knowledge but it's very hard to try to explain the finer points of disks and VMware.

Since your users apparently aren't asking for this feature, I don't expect it to be available anytime soon. However, you do have one user to add to the list.

Thanks!

So, essentially, you are using Storage Spaces to overcome 2TB VMDK size limit?

Just running some tests in the lab for 2 possible scenarios:
- Backup Repository on A Storage Spaces Volume
- FLR from a VM backup containing a Storage Spaces Volume.

will update with progress.

I'm able to replicate the OP's issue - the FLR process does not mount the Storage space volumes. This was the same historically with Server 2008 Dynamic disk sets , so I would imagine its not beyond the bounds of possibility to bring in as a feature request.

Any news on this? Will FLR from 2012 Storage Space will be supported in Veeam 7?
How about a Windows CSV Cluster?

Not in v7 as this was not specifically tested.

We are using storage spaces in W12 server, and wish to have FLR support. Unfortunately I spent hours with Veeam troubleshooting why we could not mount the drive, or only show unknown filesystem when using Other OS FLR. Reference Veeam Support Case# 00460816.

Please support FLR on storage spaces!

Live in Peace

We are not planning to add support for FLR from Storage Spaces, as Microsoft itself does not support Storage Spaces within a VM.

[MERGED] Backup of Storage Spaces drive shows no warning

Veeam Logoby ncolt » Wed Nov 11, 2015 12:54 pm

We made a Windows drive of 50000GB by merging 5 presented VMware hard disks into 1 using Storage Spaces - very exciting but I'm also required to back it up :shock:

This talk of Storage Spaces had piqued the curiosity of the storage guy who went away and did some reading. The next day he came up to me and says that Veeam probably will not be able to backup that drive at the file level. So I tested it and he looks to be right - unless you use Instant Recovery to restore the VM as per http://www.wiredinit.com/veeam-file-res ... orage-pool

The problem I have is that the test backup showed no errors but the data drive did not appear in the Guest file restore (the system drive did). If everything I'm saying is correct then shouldn't there be at least a warning in the job that the file system is not supported for Guest Files (Windows) restore?

Hi,

The main reason why you cannot perform an FLR from Storage Spaces Volume is that volumes from backup are mounted on backup server thus if your Veeam Server is not of the same Windows version as the VM being restored then it won't recognize the Storage Spaces file system, just like with HDDs that used to be behind RAID controller. The Instant-Recovery workaround is the way to go, indeed, and it's documented in our KB. Another way would be to have backup server with the same version of Windows as in VM and try to import Storage Spaces there, which is not convenient because you cannot have a separate backup server for all versions of Storage Spaces.

So, I agree with you that some sort of check should have been implemented in order to warn user about the difficulties described. Your post has been considered as a feature request, hopefully this will be addressed in future release.

Thanks for heads up!
