Virtual Machine Snapshots

• Captures state and data of a virtual machine at a specific point-in-time

• Allows rapid return to VM state and data (at specific point-in-time)

Virtual disk files.vmdk

Snapshot

vSphere• Sits in I/O path and causes I/O impact

• Consumes disk space: can impact other VMs hosted on that storage device

• High risk of data loss: if you lose the VM, you lose the snapshot

• No item-level recovery or application-awareness without a backup application

Handle with Care!

vSphere Data Protection Advanced 5.8Simple, Efficient Backup and Replication with Predictable Recovery

What is it?• vSphere Data Protection is a backup and

replication solution for simplifying and optimizing data protection in vSphere environments

Key Features• Agent-less, disk-based virtual machine backups• Application-aware, granular, agent-based data

protection for physical and virtual applications• End-to-end integration with vSphere and

managed through vSphere Web Client• Single-step recovery• Self-service File-Level Recovery• Powered by EMC Avamar

Quick to setup, Easy to use

• Deploy as a virtual appliance

• Manage backup and replication through vSphere Web Client

• Automatic VM discovery

• Wizard-driven

• Single-step recovery

• Self-service File-Level Recovery (FLR)

Application Awareness for Mission-Critical AppsBackup for Virtual and Physical Applications

In VDP Advanced Only• Agents for Exchange, SQL, SharePoint

• Database-level backup and recovery for Exchange, SQL, SharePoint

• Mailbox-level recovery for Exchange

• Backup for non-virtualized Exchange, SQL, SharePoint apps

• Support for MS Exchange DAGs, SQL Server Clusters

Key Benefits• Application consistency

• Client-side deduplication

• Granular backup and restore

• Log management

Local Data Protection + Offsite Backup Replication

Replicate backup data offsite• Target can be VDP Advanced or EMC Avamar

Restore Anywhere• Access and restore replicated backups at either

primary or DR site

Save network bandwidth costs• Patented deduplication provides network-efficient

replication• No need to configure, manage or pay for WAN

accelerators!

Keep data secure• Data in-flight is encrypted

1 Create & schedule backup job containing standalone vCenter Server VM

1 Create separate backup jobs for each vCenter VM

2 Schedule each job in a sequence (database VM, server VM, inventory service VM ..etc.)

3 Ensure each job follows same schedule (daily, weekly, monthly)

4 Perform app-consistent backup for database VM

NASVirtual SANDatastore

• Full/initial Sync– Start fresh or with seed via physical media– Compares disk IDs– Calculates checksum of all blocks at source & target– Exchanges and compares checksums to determine delta– Replicates all changed blocks necessary to align virtual

disks

• Delta sync– Writes tracked by vSCSI filter driver, which is part of the

ESX host– Tracks new blocks as they are written– Bitmap of changed blocks is maintained between

replications – Each replica corresponds to a lightweight delta– During a sync changed blocks are read and sent to the

target– No VM stun & very little IO penalty

Protecting the same VMs with both vSphere Data Protection and vSphere Replication

• Leverage the VDPA agents for application consistency

• Disable quiescing with vSphere Replication

CONFIDENTIAL 20

• Only use required RPOs

• Disable MPIT on VR if not required

• Avoid replicating with both products unless absolutely necessary
