How much data can you afford to lose?
How long can you
afford to be without
the data or service?

5. 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!

9. 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

14. • 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

20. 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
