Preparing for Disaster

Backing up VMs not enough

Backup data must be moved off-site

Preparation will avoid data loss

Many types of disasters can impact a VM environment

Preparing for Disaster

Virtualization makes backup and DR simple

Hardware independence

Image-based backups

Efficient resource

management – DRS

Automated failover and

replication

Types of Disaster Server failure = HA or FT VM corrupted = Veeam Backup & Replication, restore Datacenter failure = Replicated VM or VMware SRM

RTO vs. RPO

VM vs.

Recovery Point Objective (RPO)Recovery Time Objective (RTO)

VM business data

Amount of elapsed time allowed by business to recover data

Point time to which data must be recover

RTO and RPO negotiated to derive SLA

SRM 4 Requirements

Replication-cable SAN hardware

Site to site network requirements

High bandwidth requirements vSphere and SRM

compatibility vSphere 4, vCenter 4 needed

for SRM

SAN-based Replication

=

Hardware replication from SAN array

Continuous Data Protection (CDP)

Hardware and licensing investments

May require entire LUN replication

Frequent replication possible – but very expensive
