Veeam Backup & Replication v6
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
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
Example: scale-out
Replication Architecture
Uses proxies servers at source and target sites
Proxies communicate directly to each other
Full support for WAN acceleration appliances
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
Near-CDP capable (replicate every 5-15 minutes)
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)
Better Failover
 1-Click failover





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
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!
Real Failback
 1-Click & Confirm Failback
 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)
Improved Seeding
 Seed from backup
 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

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!
Other Features
 Replica re-homing
 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
Poll Question
Do you use any other methods for
replicating VM data in addition to
Veeam replication?
Poll Question
What Veeam data protection
capabilities are you using?
