Each and every NetApp Customer can use it for VMware Restore out of NetApp Scheduled Snapshots Multiple restores from snapshots Standard VM Backup VM snap lifetime With NetApp Integration VM snap lifetime Storage Snap • • High Load at Snapshot committ at Storage Can take some time ( hours ) Delete Storage Snap Faster commit with less data. Nearly instant VM Snapshot commit. Use of Storage Snapshot for Backup 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. Veeam Snapshot Orchestrator – Use Veeam as a NetApp Console – Create manual snapshots directly from Veeam interface – Schedule Snapshot-only “backup” jobs (lowest RPO) – SnapMirror and SnapVault orchestration for single-pass backup into two destinations (instant “Backup Copy”) Create manual snapshot Scheduled snapshot creation Configure secondary destination Every 10 min for 1 day crash consistent Snapshots (= 144) Every 4h for 1 week ApplicationConsistent & ApplicationAware Snapshots (= 42) Every 1 day for 1 month *.vbk Veeam Backup (= 30 Restore Points) Every 4h for 1 month SnapMirror/ SnapVault update (= 180 Snapshots) + optional GrandfatherFather-Son (GFS) retention weekly 5 restore points monthly 12 restore points yearly 2 restore points to disk or tape *.vbk Restore Source Restorable Objects Snapshot with VMware VMs Instant VM Recovery - Primary Snapshot VM Recovery - SnapMirror/SnapVault Snapshot Win/Linux/Unix Instant File Level Recovery - Crash Consistent or Application Consistent AD/Exchange/SharePoint Single Object Restore SQL DB Restore … Veeam Backups - On Disk - On Tape (with Disk staging) Same as above + *.vbk MS SQL Single DB Restore with logfile roll forward (with enabled Veeam logfile backup) SureBackup (OnDemand Labs + automatic restore tests) Universal Application Item Recovery 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. Data Platform VMware VMDK Licensed per virtualization host socket Restore out of NetApp Snapshot (Primary/SnapMirror/SnapVault) known as Veeam Explorer for NetApp SAN Snapshots (VMware) Veeam Backup Free Edition including Application Single Object Export (Enterprise Edition includes Application Single Object Restore to original places). Snapshots can be triggered manual or by non Veeam scheduler.

LAN (1Gbps) FibreChannel (16Gbps) *.vbk 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.
