VDP and vSphere Replication provide different data protection techniques for virtual machines. VDP uses agent-less, disk-based backups for virtual machines with capabilities like application-awareness, granular recovery, and self-service file recovery. It has an RPO of greater than 24 hours and RTO of hours. vSphere Replication provides near-synchronous replication between sites with RPO under 24 hours and RTO of minutes for disaster recovery and testing. The document discusses use cases, features, and best practices for using VDP and vSphere Replication together for backup and replication in vSphere environments.

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
