Why EMC for VMware Backup

EMC DR with VMware Site Recovery Manager



New Backup Challenges

OLD PARADIGM

Low overall utilization and plenty of bandwidth for backup

NEW PARADIGM

High overall server utilization, but low bandwidth for backup

Virtualization Changes Server, Application and Information Paradigm… Backup Must Evolve to Deliver Even Greater Consolidation and Value


Backup Methods Vary to Suit Different Use Cases

USING VMWARE CONSOLIDATED BACKUP (VCB)

TREATING VIRTUAL MACHINES AS PHYSICAL MACHINES (GUEST)

USING A BACKUP AGENT ON THE ESX SERVICE CONSOLE

Introducing EMC Avamar

Reduces the size of backup data at the source—before it is transferred across the network—reducing backup times by up to 10 times

Reduces required network bandwidth—and the amount of data backed up daily—by up to 500 times

De-duplicates across sites and servers for maximum efficiency

Cost-effectively store a greater number of full backups on disk— reducing or eliminating the need for tape

Ideal for protecting VMware environments, remote offices, LAN servers in the data center – enabling fast, reliable and secure backups over existing network connections

Revolutionizes Backup with Global, Source Data De-duplication

Target and Source De-duplication

Only Source-based De-duplication Reduces Network Bandwidth Requirements and Provides Immediate, One-step Restore

TARGET DE-DUPLICATION

Up to 50x reduction in backup storage Moves 200% of primary data weekly Backups are typically restored from full

and incremental images Data viewed as file systems and/or VTL

VMware DATA CENTER WITH VCB BACKUP

Avamar agent moves data to the Avamar Virtual Edition, data is then

replicated to the corporate data center

Avamar agent moves data to a physical single-node Avamar server, and the data is then

replicated to the corporate data center,OR

an Avamar agent can backup directly to the datacenter over the WAN.

EMC Avamar: Optimized Backup for VMware

Optimal Location: Reduces data at the source– Duplicate data never traverses congested shared resources– Data backed-up is reduced from ~ 200% to ~ 2% of primary-weekly– Significantly reduces contention for shared resources– De-duplicates within and across virtual machines and/or .vmdk files

Optimal Granularity: Sub-file, variable-length segments– .vmdk is one, large file, any changes cause an incremental/full traditional backup– Fixed-length segment de-duplication fails due to frame offset– Sub-file, variable-length segment de-duplication finds changes anywhere in .vmdk– Dramatically cuts the amount of data backed up daily– Significantly reduces daily backup time

Ideal for the protection of VMware environments– Enables fast, secure, backups over existing virtual infrastructure– Permits greater server consolidation and maximum value from VMware

Starts De-duplication at the Optimal Location and Level of Granularity

Moves minimal backup data—reduces resource contention and accelerates backups

Provides file-level restore for Windows, Linux and Solaris

Avamar Agents


Backup Built for VMware Infrastructure

Up to 95% reduction in data moved

Up to 90% reduction in backup times

Up to 50% reduction in disk impact

Up to 95% reduction in NIC usage

Up to 80% reduction in CPU usage

Up to 50% reduction in memory usage

All backups stored as “virtual full backups,” ready for immediate restore

Maintain effective consolidation ratios without over-taxing CPU utilization

Avamar Efficiently Protects Virtual Machines

Traditional moves ~200% weekly

Avamar moves ~2% weekly


VMware Consolidated Backup (VCB)

Moves backup processing off the virtual machine

Eliminate virtual machine backup traffic on LAN

Supported by major third-party backup products

Customization/extensibilitySame breakpoints and callouts as failover sequenceExtra breakpoints and callouts around the test bubble


Site Recovery Manager Core Benefits

Expand disaster recovery protection– Now any workload in a VM can be protected with minimal incremental effort and cost

Reduce time to recovery– As soon as disaster is declared, a single button kicks off recovery sequence for

hundreds of VMs

Increase reliability of recovery– Replication of system state ensures a VM has all it needs to startup– Hardware independence eliminates failures due to different hardware– Easier testing based off of actual failover sequence allows more frequent and more

realistic tests
