Standard VM Backup With NetApp Integration

High Load at Snapshot committ at Storage

Can take some time ( hours )

Backup VMware with Storage Snapshots

Example of a standard VMware API backup from a slow storage

~34 min open VMware VM

Snapshot in this example.

Veeam uses parallel Disk backup to

reduce time window but the

Snapshot is open for a long time.

This leads to a ~28min Snapshot

commit with high IO at Storage and

performance impact on the VM

With Veeam Backup from Storage Snapshots

VM Snapshot is open for a few seconds and can be committed in few seconds.

This works with FC/iSCSI AND NFS Datastores.

Use Veeam as a NetApp Console

Create manual snapshots directly from Veeam interface

It is important to not hit the max number of Snapshots per NetApp Volume (hard limit 255, never plan more than 250) with multiple Veeam Jobs. So the following recommendations should be considered:

VMware Datastore Level Scope is recommended for Veeam Jobs if you want to use Veeam NetApp Snapshot Orchestration.

It is recommended to place only 1 VMware Datastore on a NetApp volume.

If only Veeam Snapshot Orchestration is used, follow the NetApp recommendations for Datastore Size and VM count. But if Veeam Backups are created on top of Veeam NetApp Snapshot Orchestration, we highly suggest to use not more than 15TB of VMware used data on a single VMware Datastore, which lead in not more than 8TB Veeam single full backup files. It is technically possible to grow beyond that.

If you process Application Consistent Snapshots, keep an eye on the processing time for it, it can take a while for volume snapshot creation. Less VM count (round about 40-60VMs) per Datastore is helpful.

Firmware Data ONTAP 8.1 or higher (NetApp FAS, FlexArray (V-Series) and IBM N series)

Supported Access Protocols NFS, iSCSI or Fibre Channel (FC)

ONTAP-Modes 7-Mode or Clustered-ONTAP

Cloning Use of traditional LUN Cloning possible, but FlexClone Licenses are recommended for 7 mode systems.

SnapVault/SnapMirror Licenses If you want to use SnapVault or SnapMirror relevant NetApp licenses are needed.

A lab performance test of the Veeam Availability suite at NetApp Labs Munich shows that backup speed does not serve as a limiting factor for the modern data center, when customers use Veeam Backup & Replication in combination with NetApp EF- or E-Series storage.

*.vbk

LAN (1Gbps)

FibreChannel (16Gbps)

A single Veeam Backup & Replication server (2 year old Hardware) was able to scale to 700MB/s. A nearly linear performance increase was achieved when additional Veeam proxy/repository servers were added.
