What You Will Need
• Drobo model B800i or B1200i
• Drobo Dashboard management software (most recent version)
• Enterprise-grade 7200RPM SAS or SATA disk drives (recommended)
• Windows Server 2008 R2 (dedicated server recommended)
• Veeam Backup and Replication version 5
Veeam Basics
Veeam can be installed on a physical or virtual server. The advantage of installing on a physical server is
that backup storage can be directly attached and deliver the best throughput as well as attaching a tape
library to the same physical server should this is still required in addition to disk-based backup. Further,
installing Veeam as a physical server offloads the CPU burden of the backups from the VMware cluster.
Veeam Backup & Replication version 5 provides:
• File-level recovery
• Start virtual machine from the backup
• Provide replication
• Built in deduplication and compression
• Allow users to restores their own files
• Backup recovery verification
Backup Modes
Veeam Backup & Replication supports different backup methods depending on the environment. Because
Veeam takes advantage of VMware Storage APIs, Direct SAN Access is preferred because it’s the most
efficient method and will be used in this document. Three transport modes are available:
• Direct SAN Access. Supported only for VMs that reside on a block storage device (iSCSI). In Direct
SAN Access mode, Veeam runs on a physical server and backs up the VM datastores directly without
going through the ESX/ESXi host. Direct SAN Access mode also adds failover safety mechanisms. Note
that if Direct SAN Access mode becomes unavailable, Veeam fails over to Network mode in order to
complete the backup.
• Virtual Appliance. In this mode Veeam is installed on a VM and disks from the VMs that are to be
backed up are “hot-added” to the Veeam VM. Data is read directly from the storage stack instead of
over the network. The advantage of using Virtual Appliance mode is its ability to directly back up VMs
on NFS storage.
• Network The least efficient mode because the Veeam Backup & Replication server is connected to the
ESX/ESXi host over the network using Network Block Device Protocol (NBD) to connect to the VM
datastore. This adds additional network traffic and resource usage on the host, which can negatively
impact VMs running on the host.
Veeam Hardware Requirements
Veeam recommends dedicating a server to be used solely for Veeam backups. While a VM host can be the
backup server, a physical host would tend to outperform a virtual host, because resources are not shared
