EMC SnapView Accelerating Your Backup and Recovery Process


Today’s Backup and Recovery Challenges

Long backups – Limited backup “window”– Application unavailable

during backup– Labor-intensive

Longer recoveries – Unpredictable restore times– Unreliable tape backups– Costly to scale for growth– Unhappy users

High Performance, Full-Volume CopiesSnapView Business Continuance Volumes (BCVs)

Overall highest service level for backup and recovery– Fast sync on first copy, faster syncs on next copy– Fastest restore from BCVs

Removes performance impact on production volume– De-coupled from production volume– 100% copy of all production data on separate volume– Backup operations scheduled anytime

Offers multiple recovery points– Up to eight BCVs can be established against a single source

volume– Selectable recovery points in time

Accelerates application recovery– Instantly restore from BCV, no more waiting for lengthy tape

SnapView Snapshots

Moderate service levels at best economics for backup and recovery

– Fast snapshots from production volume– Takes a fraction of production space– Remains “connected” to the production volume

Creates snapshots instantly and are immediately available

– Stores changed data from a defined point in time– Utilizes production for unchanged data

Offers multiple recovery points– Up to eight snapshot sessions can be established against a

single source volume– Snapshots of BCVs are supported (up to eight snapshot

sessions per BCV)

Accelerates application recovery– Snapshot “roll back” feature provides instant

restore to source volume

SnapView—Server-based Software Integration

SnapView integration with other applications:– CommVault Galaxy Backup and Recovery for EMC SnapView– LEGATO NetWorker PowerSnap for EMC CLARiiON

SnapView works with all major backup vendors to provide serverless backup

– EMC qualified list of backup applications include:• LEGATO NetWorker• VERITAS NetBackup• CommVault Galaxy• Tivoli TSM• CA ArcServeIT

– No change required to backup application– SnapView tested and supported


Restore in seconds, not hours– One-click restore– Leverages SnapView instant restore from RAID-protected BCVs

Faster, reliable backup– Non-disruptive backup any time to disk

Enables Exchange consolidation– Backup and recovery times no longer bottleneck to database growth

Automated process:Backup: SIME acts as a VSS requestor and initiates backup to create SnapView BCVs of database and logs

Recovery: reverse synchronize BCV copy to recover Exchange database

Recovery: replay Exchange database logs from BCV

Why EMC SnapView?

Better backup and recovery– Seconds to create backup copy– Copy available in seconds– Speeds application and file recovery

Applications always available– Ensure service levels are met– Performance, availability, functions, and economics

Simple, easy to use– A Navisphere-managed application– Automation via CLI or application integrated tools (SIME, SIMS, Replication

Manager/Local)

Inexpensive to implement– Pointer-based snapshots or full-volume copies using ATA drive technology– Now runs on lower-cost platform (CLARiiON CX300)



SnapView: Understanding Service Levels

Snapshots BCVs

PerformanceProcessing against both source and pointer-based image may create performance overhead

Supports high I/O workloads without performance impact

AvailabilityRecover source volumes in the event of corruption

Recover source volumes in the event of corruption or hardware failure

Functionality

Snapshot creates pointer-based copies that are linked to the source volumeSnapshots are created instantly and are immediately available GUI and CLI based management and automation

Source and BCV are independent copiesBCVs must be established prior to splittingGUI- and CLI-based management and automation

Economics

Requires a fraction of the capacity of the source volume; amount depends on how much data changes, typically 20%

Requires 100% of the capacity of the source volume
