Business Continuity Practices for Diverse Datasets

The Authority on Software-defined Storage


• Data classification• Understand potential impact and

risks associated with each dataset• BC/DR plans must accommodate

different protection levels

Not All Data Is Created Equal


Multiple Storage Vendors


Diverse Storage Models

Traditional

Converged

Hyperconverged

Hybrid

Cloud


• Technology refresh• Mergers and Acquisitions• Datacenter move/expansion• Cloud replication• ...

Synchronous Mirroring

Zero downtime, Zero touch for Local & Stretched / Metro Clusters

• Data in two places • Eliminates storage as a single point

of failure • Enhances survivability using

physically separate nodes• Updates distributed copies

simultaneously• Mirrored virtual disks behave as

one, multi-ported shared drive• No scripting or manual intervention

Best Practice: Physically-Separated Copies

SEVERAL MILES

• Separate chassis• Different location• Independent power

• Independent cooling• Separate UPS

Asynchronous Replication

Update distant copies without impacting local performance

• Ideal for disaster recovery & remote data center migration

• Standard IP-based links • Optimizes bandwidth via

compressed, multi-stream transfers & prioritized QoS

• Bi-directional • Test readiness non-disruptively• Expedite offline initialization using

transportable media

Return to any point-in-time without taking explicit backups

Continuous Data Protection (CDP)• Restore arbitrary point-in-time • Logs and timestamps all I/Os

to the selected virtual disks• No need to quiesce or

interrupt applications• No host agents required• Easy to enable and revert from• Create known-good restore

points

Capture point-in-time images

Snapshots• Recover quickly at disk speeds to

known good state• Differential and full clones• Thin provisioned• Read / writeable• Trigger via VSS• Snap from premium storage to

lower cost equipment• Eliminate back-up window• Provide “live” copy for analysis,

development & testing
