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
