Backup is Broken

• Production system impact• Shrinking backup window• Complex tape management processes• High costs of replication and/or tape shipment• Storage vendor lock-in• RTO from 2 to 24 hours• RPO 18+ hours• Cost, cost, cost!

13

Continuous Data Protection and Snapshots

• Continuous data capture with multiple options for historical views – Up to 1000 snapshots per volume (up to 255 snapshots for NSS VA)

• Snapshots can be scheduled as well as created manually• Create readable/writeable view from any point in time• Tape and backup license savings = ROI less than 18 months

Hourly Snapshots: 24

Daily Snapshots: 30

Weekly Snapshots: 4

Data Integrity and System Recovery

Enhancing Data Protection in VMware Environments



16

VMware Recovery with FalconStor Software• FalconStor software provides a set of tools to

enhance VMware data protection– 100% transactional integrity of data for fast restores – WAN-optimized data replication to reduce

bandwidth use by 90% or more– Integration with VMware vCenter Site Recovery

Manager (aka SRM)– Physical-to-virtual, Physical-to-physical, and

Virtual-to-virtual with FalconStor RecoverTrac™ technology



17

Application-centric Protection

Why is application integration important?

Because when you recover, you want your data to look like this

And not like this

Crash Consistent Data

Transactionally Complete Data



18

FalconStor Snapshot Director for VMware

• FalconStor Snapshot Director for VMware is designed to ensure transactional integrity of data– Data is not in a crash consistent state (it is 100%

transactionally consistent)– No need for lengthy system/DB checking

• Coordinates snapshot process between VMware vSphere/vCenter and FalconStor NSS (optional application-specific and filesystem snapshot agents)

• Runs as a Virtual Appliance on vSphere• Integrates with Site Recovery Manager (aka SRM)



19

Where Do the Pieces Fit?

Application Snapshot Director is a separate virtual machine

Application-specific agents install within the virtual machine (optional)

Datastore Snapshot (other vendors)• Datastore contains more than one

Virtual Machine (VM)• Can not guarantee data integrity on

each VM.

FalconStor SDVA for VMware vSphere• install SDVA on vSphere host.• install DB agent on each VM (optional)• NSS initiate snapshot and notify SDVA• SDVA queries vCenter for VM list/info• SDVA redirects the snapshot

notification to DB agent on each VM to trigger DB into backup mode.

• Take snapshot on VMFS Datastore. 100% Guarantee data integrity for all VMs.

Storage Virtualization and Site Recovery Manager



23

The Importance of Site Recovery Manager

• VMware Site Recovery Manager is a critical disaster recovery tool

• Provides automation of DR processes

• Provides automation of DR testing

• Provides reporting for proof of compliance



24

Challenges for Site Recovery Manager Implementation in the Enterprise Space

• Array-level replication• Limited number of disk vendor certifications for Site

Recovery Manager• Array Vendor Storage Replication Adapter (SRA) is

platform specific• Need the same hardware on both primary and remote sites• Limited product certifications

• Need to change the underplaying infrastructure at the primary site, the secondary site, or both

• Breaks the virtualization promise of platform independence



25

Challenges for Site Recovery Manager Implementation in SMB Space

• vSphere Replication newly introduced in SRM 5• Lack of support for failback• No application integration for improved RTO



26

Integration with Site Recovery Manager

• FalconStor Storage Replication Adapter (SRA) integrates FalconStor replication with VMware vCenter Site Recovery Manager

• FalconStor CDP or FalconStor NSS provides replication engine

• Virtual disk assignments are automatically coordinated with associated virtual machines with the help of FalconStor SRA

• Disaster recovery scenarios can be tested at any time– A TimeView™ snapshot image is created and mounted to a virtual

machine being tested

– The virtual machine is started

– Recovery is validated and the TimeView image is removed

FalconStor Storage Virtualization Device

• FalconStor CDP and FalconStor NSS Gateways are certified for vCenter Site Recovery Manager

• Allows any SAN storage on VMware Hardware Compatibility List (HCL) to be used with Site Recovery Manager

– In effect, FalconStor DR solutions extend Site Recovery Manager certification to connected disk

• Increases storage array flexibility for VMware Site Recovery Manager, brings support to existing SAN

• Allows Site Recovery Manager testing without breaking the replication stream

WAN Optimization



40

Achieving Efficient Data Replication

Deploy sub-block replication to move your data



41

MicroScan™ WAN Optimization

• Applications and file systems write far more data to disk than actual changes

• FalconStor solution scans the changes at a 512 byte disk-sector level and replicates only the changed data– Avoids constant re-

sending of duplicate data

512 byte

= empty disk sector

= data written by application or file system

= sector with actual data change

A typical 8k write of data. Many systems send all 8k or more. FalconStor CDP and FalconStor NSS send

only the truly changed sectors.
