3. Veeam Backup & Replication v6
Give quick overview of total product
Backup: Snapshots, CBT, inline dedupe and compression and incremental file set. Leverage VSS for application-aware backups.
Surebackup: 100% reliability
Replication: 2-in-1 solution, get a near CDP solution at a fraction of the cost. Both our backups and replication will give you the best RTO’s and RPO’s.
Recovery: U-AIR, IFLR and Instant VM Recovery (breakthrough technology).

4. Why replication?
It’s not just a commercial bundling of products… it’s a cohesive data protection strategy
Virtualization enables cost-effective replication
Simple failover to dissimilar hardware and storage
Cheap standby environment: single host for multiple replicas
Quick, simple restore: whole VM (not application-specific)
Virtualization enables unified data protection
Image-level, incremental backup for all VMs
Image-level, incremental replication for tier 1 VMs
Only difference is the target
Hypervisor-agnostic approach

5. New distributed architecture
Better performance with lightweight proxies that act as data movers
Simplified deployment and maintenance of remote/large scale installations
Allows more efficient replication over WAN

6. Example: scale-out

7. Replication Architecture
Uses proxies servers at source and target sites
Proxies communicate directly to each other
Full support for WAN acceleration appliances
Near-CDP capable (replicate every 5-15 minutes)
Source proxy (VM or physical)
Retrieves changed blocks incrementally
Compresses and deduplicates the data
Sends incremental change data file to target proxy
Target proxy (VM or physical)
Receives incremental change data
Decompresses the data
Injects data into the new replica restore point

8. Faster Replication 10x faster… How?
vStorage API Hot Add (“Virtual Appliance” mode) for writes
Hot Add leverages ESXi storage I/O stack
Much faster than ESXi network stack (NBD mode)
Unlike direct SAN access mode, performance does not suffer with thin provisioned disks (most commonly used)
v6 even uses the same approach for full VM restores!
Traffic compression
WAN traffic is heavily compressed
Configurable compression level to control proxy CPU load
Turn on or off (for WAN accelerators compatibility)
Re-homing: replica is the new production, make it that way
“Real failback” means everything failback should do

9. Better Failover 1-Click failover Automatic job updates
Automatic re-IP to match DR site
Automatic virtual network update to match DR site
Replica VM placement settings are now a part of the job
Full support for DVS switches
Multi-select operations
Automatic job updates
Failover and failback processes automatically update the replication job to exclude/include VM

10. Better Failover (continued)
Active rollbacks for VMware
Each replica restore point is stored as a VM snapshot
Every restore point is immediate available
Instant power-on – no VMDK rebuild required before failover
Can start any restore point in vSphere Client or from PowerCLI
Replica state protection
Failed replication pass no longer leaves the latest restore point inconsistent until the next pass
Powering any replica restore point for testing does not change the actual restore point (changes are redirected)
Retention processing is about simple snapshot commit!

11. Real Failback 1-Click & Confirm Failback Failback commit Delta sync
Fully automated (includes backward re-IP)
Confidently failback knowing you can always go back
Failback commit
Instantly go back to replica if the new VM (failback target) is not working as expected
Or commit failback for automatic replica clean up, and required job updates (aka “re-protect”)
Delta sync
Transfers only the differences back to original VM
Original VM gone? No problem!
Restore it from backup, delta-sync will take care of the rest
Failback with no target VM is also supported (full sync)

12. Improved Seeding Seed from backup Seed anywhere Replica mapping
Up to 10x smaller seed size
Keeps thin provisioned disks thin
Seed anywhere
Veeam server placement no longer affects the ability to seed
Replica mapping
Map replicas to existing VMs in DR site
Reuse VMs produced with a different replication job, or VMs restored from backup
First job run will only transfer the differences between source VM disks and mapped VM disks
Replica mapping: use existing replicas for a new job (tied to seeding)
Replicate to cluster: rather than a specific host

20. Shared engine features
Traffic throttling
Defines rules based on source/target IP address pair
Global – divides available bandwidth between all proxy serves
Flexible – rules can be enabled depending on time of the day
Swap exclusion
Excludes disk blocks backing swap files from processing
Enforceable processing windows
Jobs crossing the defined replication window are automatically terminated (prevents snapshot commit during prod hours)
Simplified scheduling
Overlapping backup and replication no longer causes either job to fail – no more baby-sitting your schedules!

21. Other Features Replica re-homing Replicate to cluster
Makes the replica your new production VM (automatic cleanup)
Helps greatly with data center migrations projects
Replicate to cluster
Ensures that replication can continue even if current replica host is unavailable

22. Poll Question
Do you use any other methods for replicating VM data in addition to Veeam replication?
