Backup of VMs on SMB3

With Hyper-V 3.0, Microsoft provides the ability to store VM files on SMB3 file shares. Veeam Backup & Replication introduces support for VM files residing on SMB3 shares and lets you perform backup, replication and file copy operations for such VMs without taking VMs offline. Veeam Backup & Replication works with both standalone and clustered SMB3 servers.

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

To be able to work with SMB3 shares in Veeam Backup & Replication, you must meet the following requirements:

1. Make sure that your SMB3 shares are properly configured. For a full list of requirements for SMB3 shares, see the Requirements and supported configurations section at http://technet.microsoft.com/en-us/library/jj612865.aspx.
2. Add the SMB3 server or SMB3 cluster hosting the necessary file shares to the Veeam Backup & Replication console. Otherwise Veeam Backup & Replication will not be able to use the changed block tracking mechanism for VMs residing on SMB3 shares.
3. Make sure that VMs you plan to work with are not located on hidden shares or default shares like C$ or D$. When re-scanning SMB v3 file shares, Veeam Backup & Replication skips these types of shares.
