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

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

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
