Specifically for NetApp Data ONTAP, Veeam offers some specific additional capabilities.
Backup from Secondary Snapshots. In case you use NetApp SnapVault or SnapMirror, Veeam can create a primary snapshot, update the secondary (SV/SM) Snapshot and backup the CBT changes to the backup file. It is configured with a job setting in the "Advanced" section if Veeam should allow fallback to the primary snapshot for backup. You can find the setting within the secondary destination window of your backup job and enable “Use as the data source”.
For NetApp ONTAP storage systems Veeam offers a SnapShot Orchestration only feature. SnapShot orchestration means to use storage SnapShots as backup target. The feature can be used without any need to run a real backup to an external repository. Veeam is taking care of all required storage related tasks like data retention, SnapShot management and SnapMirror/SnapVault updates to secondary sides.
The workflow for Storage Orchestration is:
(Optional) Application-aware processing ensures transactional consistency
within the VM
Veeam requests a VM snapshot via VADP
Immediately after creating the VM snapshot, a storage snapshot
request is issued for saving the VM including the application
consistent VM snapshot within the storage snapshot.
When the storage snapshot has been created, the VM snapshot is
Trigger a replication update to secondary storage via SnapMirror or
To configure a “SnapShot only” job set the Repository to "NetApp SnapShot only"
The retention policy defines the number of storage snapshots to keep. To store 5 snapshots a day for 1 week, configure the retention to 35 restore points with a daily schedule. If the job is configured with a high or lower schedule frequency, adjust the number of restore points accordingly.
If you use a secondary NetApp ONTAP system with SnapMirror and/or SnapVault you can set the box for a secondary destination and set the retention.
When using Snapshot Orchestration please take care of the retry scheduler setting.
If you have for example 100 VMs in one job and 10 of these VMs are failing in the first run Veeam will rerun the job based on the retry settings. If the setting is set to 3 (default) Veeam will try 3 more time to process the failed VMs. For every successful retry Veeam will create a new Snapshot. If all retries are needed to proceed the failed VMs that ends in 3 Snapshots for one run. It is recommended to not set the value higher than 3 or disable the automatic retry to avoid a high number of Snapshots being created during every run.
One of the big benefits is that you are still able to use all Veeam restore capabilities from storage snapshots. For more please refer to the Veeam Explorer for Storage Snapshots section.
