Data Protection Challenges FalconStor Network Storage Server (NSS)

Data Protection Challenges Not enough protection Backing up data once a day does not provide enough coverage Recovery Point Objective of 24 hours needs to be significantly reduced Recovery takes too long Restoring from tape is a lengthy process Recovery Time Objective must shift from hours to minutes Application downtime is unacceptable

Not enough protection

Backing up data once a day does not provide enough coverage

Recovery Point Objective of 24 hours needs to be significantly reduced

Recovery takes too long

Restoring from tape is a lengthy process

Recovery Time Objective must shift from hours to minutes

Application downtime is unacceptable

Data Protection Challenges Disaster recovery is costly, limited, inefficient and risky DR setups are extremely costly and difficult to test/verify Tier 2 and Tier 3 data often unprotected Data protection costs are out of control Disk space, power and cooling needs are consuming IT budgets. Data “consumers” continue to increase their demands and drive storage usage Remote site protection costly and inefficient

Disaster recovery is costly, limited, inefficient and risky

DR setups are extremely costly and difficult to test/verify

Tier 2 and Tier 3 data often unprotected

Data protection costs are out of control

Disk space, power and cooling needs are consuming IT budgets.

Data “consumers” continue to increase their demands and drive storage usage

Remote site protection costly and inefficient

How does CDP work? FalconStor Network Storage Server (NSS)

How Does CDP Work? CDP copies data writes (not reads) to separate storage device Maintains full mirrored copy plus journal and delta snapshots 1-10 Gig Ethernet 2-8 Gb FC or 1-10 Gb iSCSI SAN Storage CDP Storage Appliance 8:00 9:00 10:00 11:00 Host-based write-splitting for DAS, via iSCSI Fabric-based write splitting for Fibre Channel/iSCSI SANs Journal

CDP copies data writes (not reads) to separate storage device

Maintains full mirrored copy plus journal and delta snapshots

CDX Appliances, SANtap Fabric-based mirroring, host-agnostic All storage services performed out-of-band If primary storage fails, CDP mirror provides seamless takeover of data processing Write-data is mirrored, read-data is pass through CDX devices Similar switch-based deployment with Cisco SANtap IP/FC Writes are mirrored Reads are pass-through 8:00 9:00 10:00 11:00 Bootable mirror disk Primary SAN storage Full QoS on mirror

Fabric-based mirroring, host-agnostic

All storage services performed out-of-band

If primary storage fails, CDP mirror provides seamless takeover of data processing

Write-data is mirrored, read-data is pass through

Simplify Server Protection FalconStor DiskSafe For Windows: DiskSafe host-based mirroring software Less than 5% CPU utilization For Unix/Linux: volume managers supported Manage protection from DiskSafe GUI on application server or from CDP console IP/FC 8:00 9:00 10:00 11:00 Bootable mirror disks Writes are mirrored Full QoS on mirror

For Windows: DiskSafe host-based mirroring software

Less than 5% CPU utilization

For Unix/Linux: volume managers supported

Manage protection from DiskSafe GUI on application server or from CDP console

Not Enough Protection CDP provides any point in time recovery Reduce corporate risk/exposure by capturing every transaction of high-value applications Change RPO from days to seconds

How Much Protection Do You Need? CDP has two modes Continuous/Journaling: every write is captured allowing write-by-write recovery Periodic: data is captured at intervals, (e.g. every 15 minutes, every hour, every four hours, etc.) How often do you capture your data today? Still backing up once a day? Most are. How often would you like to protect your data? Not everyone needs per-write data capture (but some do) Do you need to increase your frequency of data protection?

CDP has two modes

Continuous/Journaling: every write is captured allowing write-by-write recovery

Periodic: data is captured at intervals, (e.g. every 15 minutes, every hour, every four hours, etc.)

How often do you capture your data today?

Still backing up once a day? Most are.

How often would you like to protect your data?

Not everyone needs per-write data capture (but some do)

Do you need to increase your frequency of data protection?

Continuous or Periodic Data Capture? Continuous data capture is needed if every transaction on a volume is considered critical If you have zero tolerance for lost transactions ($$$) Periodic capture is good enough for most Recovery Point Objectives and much better than once a day backup E.g. capture data once an hour and you have 24X more protection than once a day backup

Continuous data capture is needed if every transaction on a volume is considered critical

If you have zero tolerance for lost transactions ($$$)

Periodic capture is good enough for most Recovery Point Objectives and much better than once a day backup

E.g. capture data once an hour and you have 24X more protection than once a day backup

Continuous Data Capture plus Historical Views Continuous data capture with multiple options for historical views Combine full CDP with near-CDP snapshots Up to 255 snapshots per volume Full Journaling: 4 hours Hourly Snapshots: 24 Daily Snapshots: 7 Monthly Snapshots: 5 Example Snapshots can be scheduled as well as created ad hoc with markers Create readable/writeable view from any point in time

Continuous data capture with multiple options for historical views

Combine full CDP with near-CDP snapshots

Up to 255 snapshots per volume

Snapshots can be scheduled as well as created ad hoc with markers

Continuous Data Capture plus Historical Views Easy to use interface for snapshot scheduling Consistency groups to snap multiple application volumes simultaneously Manage snapshots from the host-side or from the CDP device

Easy to use interface for snapshot scheduling

Consistency groups to snap multiple application volumes simultaneously

Manage snapshots from the host-side or from the CDP device

Recovery Takes Too Long Bring your business critical applications back on line quickly Instant recovery improves corporate revenue, productivity and customer satisfaction Change RTO from hours to minutes

It’s More Than Just Recovering Data You are not recovering “data,” you are recovering your business Application downtime means Lost opportunities Lost transactions/sales Failure to service customers Diminished productivity as employees sit idle or have to re-create lost work Tape restore is too slow and unreliable

You are not recovering “data,” you are recovering your business

Application downtime means

Lost opportunities

Lost transactions/sales

Failure to service customers

Diminished productivity as employees sit idle or have to re-create lost work

Tape restore is too slow and unreliable

Moving from “Restore” to “Instant Recovery” CDP changes “restore” into “instant recovery” “ Restore” involves spooling data back to a target Mountable/bootable images mean data can be instantly accessed to recover from any kind of failure Rollback to any transaction Boot from drive images Recover data from multiple points in time C: Journal iSCSI or FC / D: D: D: 8:00 9:00 10:00 /home /home /home

CDP changes “restore” into “instant recovery”

“ Restore” involves spooling data back to a target

Mountable/bootable images mean data can be instantly accessed to recover from any kind of failure

Continuous or periodic modes

WAN optimized out of the box

Includes WAN data encryption, compression and QoS

WAN Optimized Data Replication Applications and file systems write far more data to disk than actual changes CDP scans the changes at a 512 byte 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. CDP sends only the truly changed sectors. 512 byte Disk sectors

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

CDP scans the changes at a 512 byte level and replicates only the changed data

Avoids constant re-sending of duplicate data
