When you perform restore from storage snapshot on NetApp storage systems working over the NFS protocol, Veeam Backup & Replication triggers NetApp to clone an NFS share that holds VM data. NetApp creates a copy of the NFS share and places this copy on the same volume where the original NFS share is located. This copy is used as a data source restore operations.
After the copy of the NFS share is created, Veeam Backup & Replication mounts the NFS share copy to the ESX(i) host as a new datastore.You can restore VM data from the mounted NFS share copy.
If you have several VMs that reside on the same storage snapshot, Veeam Backup & Replication will create only one NFS datastore per snapshot. During restore, VMs from the same snapshot are copied to the same folder on the volume where the original NFS share is located. The folder is presented as a datastore to the ESX(i) host when you start the restore process for the first VM on the storage snapshot. The folder is unmounted from the ESX(i) host after you finish the restore process for the last VM on the storage snapshot.
Veeam Backup & Replication uses different technologies to create a clone of the NFS share.
7-mode:
If the NetApp storage system operates in the 7-mode, you must have a FlexClone or SnapRestore license installed or the NDMP protocol enabled.
Veeam Backup & Replication uses the following technologies for LUN clone creation:
- If you have a FlexClone license installed, Veeam Backup & Replication uses the FlexClone technology.
- If you have a SnapRestore license installed, Veeam Backup & Replication uses the SnapRestore technology.
If neither FlexClone nor SnapRestore license is installed, Veeam Backup & Replication uses the NDMP protocol. If the NDMP protocol is not enabled, VM data restore will fail.
|
[For Instant VM Recovery] Veeam Backup & Replication performs actual Instant VM Recovery only if the FlexClone license is installed. If the SnapRestore license is installed or the NDMP protocol is enabled, Veeam Backup & Replication performs full VM restore instead of Instant VM Recovery, which takes more time. |
C-mode:
If the NetApp storage system operates in the C-mode, you must have a FlexClone or SnapRestore license installed.
- If you have a FlexClone license installed, Veeam Backup & Replication uses the FlexClone technology.
- If you have a SnapRestore license installed, Veeam Backup & Replication uses the SnapRestore technology.
If neither FlexClone nor SnapRestore license is installed, Veeam Backup & Replication will fail to perform Restore from Storage Snapshots.
Restore from SnapVault
7-mode:
If the NetApp storage system operates in the 7-mode, you must have a FlexClone or SnapRestore license installed or the NDMP protocol enabled.
- If you have a SnapRestore license installed, Veeam Backup & Replication uses the SnapRestore technology.
- If a SnapRestore license is not installed, Veeam Backup & Replication uses the NDMP protocol. If the NDMP protocol is not enabled, VM data restore will fail.

[For Instant VM Recovery] If you restore data from SnapVault, Veeam Backup & Replication performs full VM restore instead of Instant VM Recovery, which takes more time. |
C-mode:
If the NetApp storage system operates in the C-mode, you must have a FlexClone license installed. In the opposite case, VM data restore will fail.
