Virtualisation and business continuity - where the wild gaps are

Virtualisation & Business Continuity
Ian Masters, UK sales director

Introduction
With solutions for Windows®, Linux®, AIX® and IBM®i, Vision leads the way in keeping systems and applications resilient and available
Personally working in the high availability and disaster recovery for Windows® space since 1996

Virtualisation advantage?
virtualisation brings its own availability tools
but virtualisation could be its own worst enemy when it comes to availability

Virtualisation advantage?
With minimal, incremental investments, IT managers can use virtualisation as an HA platform

VMware tools
the VMotion® and Storage VMotion functionality in vSphere makes it possible for organisations to dramatically reduce planned downtime
VMware HA provides rapid recovery from outages
shared storage is a single point of failure
local availability only
VMware fault tolerance provides continuous availability

Hyper-V tools
Hyper-V™ live migration allows you to move running VMs from one Hyper-V™ physical host to another

Hyper-V tools
failover clustering at the Hyper-V host level
clustering at the Hyper-V guest level
clustering at the Hyper-V guest level on a single physical server
Physical server is a single point of failure

Virtualisation disadvantage?
some HA techniques and technologies, however, outstrip the capabilities of virtualisation platforms
what do you do if you run more than one hypervisor?
what do you do for DR?
what happens if you use more than one storage platform or vendor?

Virtual backups
there are some very simple, yet far-reaching challenges to deal with when it comes to virtualisation backup
when you plan a backup and recovery strategy for a virtualized server environment, there are several factors to consider

Virtual backups
if a virtual machine is expected to be up-and-running for example, there is nothing to preclude treating it as a traditional physical machine and backing it up accordingly
a backup can be run on the host physical machine and backup the VHD or VMDK for example

Virtual backups
tools such as snapshots and cloning can help
plenty of options, online vs. offline, streamed vs. snapshot, guest vs. host

Virtual backups
in-guest
Snapshots
VCB
Third party tools

Is there a solution?
replication could provide the answer...
works across all virtualisation platforms
works across storage platforms & vendors
works with physical & virtual servers

Is there a solution?
migrate P2P, P2V, V2P and V2V all with zero user downtime
failover between any combination of physical and virtual servers, between mixed hypervisors, across any distance
recover individual files, emails, data and system states from latest copy or previous point-in-time
