Backup of VMs on Microsoft SMB3

Microsoft Hyper-V provides the ability to store VM files on SMB3 file shares. Veeam Backup & Replication works with both standalone and clustered SMB3 servers. It supports VMs whose VM disks are located on SMB3 shares and lets you perform backup, replication and file copy operations for such VMs without taking VMs offline.

The procedure of backup depends on the Microsoft Hyper-V Server version:

Microsoft Hyper-V Server 2012 R2 and Earlier

In general, VM quiescence and backup or replication of VMs on SMB3 shares is similar to backup or replication of VMs hosted on local storage and CSV. However, SMB3 brings in some specifics.

If you want to work with SMB3 shares in Veeam Backup & Replication, the backup infrastructure must meet the following requirements:

Microsoft Hyper-V Server 2016 and Later

For backup of VMs registered on Microsoft Hyper-V Server 2016 and later versions, Veeam Backup & Replication uses a new mechanism based on production checkpoints. For more information, see Backup of VMs on Microsoft Hyper-V Server 2016.

If you plan to process VMs whose disks reside on SMB3 shared folders registered on Microsoft Hyper-V Server 2016 or later, it is not obligatory to add the SMB3 server to the backup infrastructure. However, if you do not add the SMB3 server, you will not be able to specify the Max snapshots and latency control settings for SMB3 shared folders.

The mentioned above applies to SMB3 shares running on Microsoft Windows or any other non-Windows based SMB3 source.
