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 ArchitectureUses 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)

Target proxy (VM or physical) Receives incremental change data Decompresses the data Injects data into the new replica

restore point

Source proxy (VM or physical) Retrieves changed blocks

incrementally Compresses and deduplicates

the data Sends incremental change

data file to target proxy

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?
