Server Virtualization

Local backup only

Disk capacity exceeds tapecapacity

Centralizes backup at the server

Data exceeds the size of a singletape cartridge

Open systems tape automation

enables unattended backup for aweek

Central backup server enablesresource/media sharing

Simplifies administrationIntroduces scale

But it creates LAN traffic andelongates backup

NAS allows networked servers toshare storage space with

networked clients

Contributes to data growth

SANs provide high-speed network ofstorage

Improves resource utilizationImproves backup/recovery performance

Eases congestion on LAN

Emulating tape on disk enablesseamless integration of disk in

backup processes

Accelerates backup & recovery

Disk enables new data capturetechniques

CDP captures multiple recoverypoints, improving both RPO &

RTO

Deduplication in storage systemseliminates redundancy changes

the economics of disk-basedbackup

Lower-cost disk expands D2D andD2D2T backup

Penetration of broadband Internetaccess and bandwidth

optimization makes SaaS feasible

Deduplication becomes morepervasive in backup applications

Source-side deduplicationprovides end-to-end efficiency

Backup vendors mix capturemethods with disk & tape via

single policy engines/interfaces todeliver tiers of RTOs/RPOs

Server virtualization breaks

traditional backup approaches

Alternative capture techniques(image-level backup, CDP,

Snapshot) gain

Cloud-based storage tier rivalstape as off-site, long-term

retention medium

Non-traditional data protection atthe storage system gaining in

popularity

Policy-driven data protection determination of capture

technique, frequency, and copys

destination automaticallydetermined by recoveryobjectives

File Storage & IP Network Growth

Linear Tape File System (LTFS)

works in conjunction with LTO5tapes and libraries; making dataon tape as easy to access as data

on disk

Snapshot & CDP more likely to replace traditional backup

23% electing snapshot to replace file-level backup

14% of organizations electing CDP to replace file-level

backup

18% replacing backup with a combination of snapshot & CDP

Virtual Machine Backup/Recovery Challenges

Resource contention

Non-virtualized servers benefit from dedicated andunderutilized resources

Virtualized servers share available physical resources,improving utilization

Simultaneous resource-intensive processes on a physical

host could impact the pool of virtual workloads sharingcommon resources, causing performance issues

VM disk image files are active

Must be quiesced before backup

Growth in data volume

VM image files increase the amount of data backed up andtransferred over the network due to proliferation andredundancy


26/42

File-/Application-Level Backup

Backup agentinstalled in VM

Backup Mode Files and application objects

Backup Process Typically requires an VM-residentagent to locate and back up

files/applications.

Recovery Mode File-level or application object only

Recovery Process Re-install OS, applications onreplacement hardware, and then

recover dataAdvantages Familiar method like physical

environment backup

Facilitates single-step file-level

recovery and transaction-consistent

recovery for applications

Disadvantages Potential for resource contention ofhosts shared resources

No BMR-like recovery of whole VM

Requires agent in guest OS

VM-Level Backup via Proxy (VMware)

Backup agentInstalled on

Backup Mode VM disk image

BackupProcess

Uses hypervisor API to capture point-in-time snapshot of VM

Recovery Mode Whole VM (like BMR)Single-step individual file and/or

application object recovery depends on

capabilities of backup application

RecoveryProcess

Recover VM image to a proxy, and thenrecover one or more files

Advantages Non-disruptive to the virtual machine-resident applications

Wont overwhelm the hosts CPU

Eliminates backup window

Eliminates need for an agent in every VMFull VM recovery enabled

Disadvantages Requires a virtual or physical proxyserver on the network

Requires networked storage

May or may not require a backup agent onthe host or guest OS to facilitate backup

Recovery Mode Whole VM (like BMR)

Single-step individual file and/or

application object recovery depends on

capabilities of backup application

RecoveryProcess

Recover a VM image to a virtual or physicalmachine; recover one or more files

Advantages Non-disruptive to the virtual machine-

resident applications

Wont overwhelm the hosts CPU


Eliminates need for an agent in every VM

Full VM recovery enabled

Disadvantages


29/42

SAN Snapshot BackupBackup Mode VM disk image or VM datastore

Backup Process SAN-based snapshot

May use an agent on physical system toprovide visibility

May or may not be application consistent

Recovery Mode Whole VM

Single-step file &/or application object

recovery depends on software capabilities

RecoveryProcess

Select desired recovery point stored on diskand restore VM

Advantages Non-disruptive to the virtual machine-

resident applications


No need for proxy server

Full VM recovery enabled

Can streamline remote replication

Disadvantages Can be unreliable if not configured properly


30/42

Optimization of VM Backup/Recovery

Reduce the load on VMs

Accelerated backup via VM-level capture

Transfer less data

BLIB

Deduplication

Read/write directly from/to VM storage

VM-level backup with file-level restore

Rapid recovery via volume-level restore

Auto-discovery of unprotected VMs & auto-assignment

38/42

Cloud Services Models for Backup

SaaS outsource backup completely Bandwidth determines data set sizes

Best use cases: ROBOs, endpoint devices

Cloud storage off-site and/or long-term retention in

cloud repository Potential tape replacement strategy

Cloud storage & compute create cloud failover point

P2V/V2V disaster recovery


39/42

Summary

Data growth and innovation is driving greater use of

disk in data protection

Innovation shift from back-end to front-end optimization in

backup

IT organizations using combinations of disk, tape &

cloud tiers for data protection

Greater use of cloud computing & SaaS will result in backup being

out-tasked to service providers hosting the data

Virtualization is a change event creating

opportunities for next-generation data protection

Single solution for physical and virtual backup is preferred
