Veeam backup to big Storage Space volum

[its-user01]

I would like to make a big volume based on Microsoft Storage Space, and then let Veeam use that volume for all jobs. However, is there a limit for such a volume based on Storage Space? Write now i have a volume on 103TB, and it all Works fine.

I think you are going well with that.
I had a look at the Storage Spaces FAQ's and it says the following: https://social.technet.microsoft.com/wi ... s-faq.aspx

The following are the recommended configuration limits for Storage Spaces:

For clustered storage pools:

Up to 80 physical disks in a clustered storage pool (to allow time for the pool to fail over to other nodes)
Up to four storage pools per cluster

For non-clustered storage pools:

Up to 240 physical disks in a non-clustered Windows Server 2012 R2 storage pool (4 x 60 disk JBOD); you can, however, have multiple pools of 240 disks
In Windows Server 2012, you can have up to 160 physical disks in a storage pool; you can, however, have multiple pools of 160 disks.

For both clustered and non-clustered pools:

Up to 480 TB of capacity in a single storage pool
Up to 64 storage spaces in a single storage pool
Up to 10 TB per virtual disk when using persistent VSS snapshots and the Volsnap VSS system provider

So if you have a Pool with 103 TB this should be fully supported.

I would like to make an 400TB Storage Pool and one 400TB Virtual Disk. And form that, make a Volume on the server on 400TB. Should that Work?

Hi Brian, according to the numbers above, you're good in terms of the storage pool size. However, are you going to store your backups on a virtual disk? It is not the best practice.

Virtual disk?? I make one Storage Pool via Microsoft Storage Space, and create one Virtual Disk from that. Is that not best practice?

Ok, I mixed up VM virtual disk with logical volume in Storage Spaces, sorry for confusion.
