EMC Avamar

EMC Avamar is a deduplication backup-and-recovery software and system solution. It performs

deduplication on the client, which eliminates data from backup streams before it crosses the network.

Client deduplication realizes savings on bandwidth, storage, and backup windows. VMware’s

vStorage API (in vSphere as deployed in Vblock systems) also provides the ESXi hypervisor

architecture.

EMC Avamar virtual machine image proxy

Avamar image proxy servers are a key element of image-level protection. They are delivered as

vSphere-deployable Open Virtualization Archive (OVA) templates. An OVA template contains a

packaged image proxy virtual machine that includes both VMware and Avamar code for the purpose

of image-level backups and recoveries. This machine is configured with a single CPU and consumes

1 GB of memory. Avamar image proxy machines use the VMware vStorage APIs to mount the virtual

machine files that require protection. The administrator has the flexibility to deploy multiple proxies

based on the operating system environment requirements. Multiple proxy deployments allow

simultaneous backups and recoveries. During the initial deployment, the administrator assigns

separate proxy servers to protect Windows and Linux virtual machines (VM)

EMC Avamar file-level recovery proxy

An Avamar file-level recovery proxy is a VM that allows a single file to be recovered into a VM from a

full image backup. Avamar file-level recovery proxies require a VM that is running Windows Server

2003 SP2. EMC recommends one CPU and 1 GB of memory for this VM. This proxy VM leverages

the Avamar Virtual File System (AvFS) to create a browseable view within a VM’s VMDK file for easy,

selectable recovery.

VMware vCenter Server

VMware vCenter Server provides a scalable and extensible platform that forms the foundation for

virtualization management. It centrally manages VMware vSphere environments and allows IT

administrators to dramatically improve control over the virtual environment. It manages the ESXi

server, VMs, and user access, and helps provide Avamar with the information it requires. This

information can encompass anything from a simple list of VMs within the environment to the

information needed to configure VMs for backup and recovery.

VMware ESXi

VMware vSphere is the virtualization platform that provides the foundation for the private cloud. The

core VMware vSphere components are the VMware ESXi enterprise hypervisor and VMware vCenter

Server for management. The VMware vSphere ESXi hypervisor runs in the Vblock systems.
