Agenda and objectives

Background on Veeam Backup & Replication and vPower

Define how Veeam deduplication works ● Source-based

Best way to organize jobs for optimal deduplication

Demo ● Job configuration and write behavior

Veeam Backup & Replication

Reality check!

All virtual machines are not created equal

All source storage controllers are not created equal

All backup targets are not created equal

Compression and deduplication

With Veeam: These go well together ● Extra considerations if using a deduplication appliance (discussed

later)

● Compressed data does not deduplicate well

● Job options

Included with all editions of Veeam Backup &

Replication (vSphere and Hyper-V)

Enabled by default for backup jobs

What is Veeam’s source deduplication?

The VMDK and VHD files are the source data

Regions are hashed for matches within that virtual

machine or other virtual machines in that job ● Match: Pointer is inserted

● Non-match: Data transfer

Veeam doesn’t own the disks (source or target)

Regions are fixed-size: ● WAN/256 KB: Least bandwidth, most dedupe, highest CPU

● LAN/512 KB: Medium bandwidth, middle dedupe, medium CPU

● Local/1 MB: Most bandwidth, least dedupe, least CPU

How it works

512 KB example

Deduplication and compression configuration

Job options

Hyper-V and VMware have the same options for jobs

(Storage tab) for deduplication and compression ● Proxy moves data to processing engine in similar manner

Jobs can include one or the other type

Repository Options

v6 includes deduplication enhancement for repository

Best deduplication helpers: Templates

Same source template will provide best deduplication

Including one-offs are fine ● Example: Domain controllers for vPower

Recommendation: Gravitate to the vSphere folder for

backups ● Also consider datastores as containers

Next best thing: Same OS

Same operating system, whether or not from same

template will also help deduplication ● Slight variance from series: Enterprise, Standard, etc. on Windows

Deduplication of a job with Linux, Windows and others

will not do well.

Deduplication appliances

Requires consideration and best configuration options ● vPower tasks push storage to perform like primary storage resources

Configuration tweaks for virtual machine profile ● Disable compression on jobs

● Consider disabling deduplication within Veeam

Demo

Deduplication behavior

Job with no compression and deduplication

Job with default compression and deduplication

Job with repository configuration for deduplication

Best case deduplication job example

General recommendation

Examine data profile

Tweak job options to best meet all needs

Performance

Storage allocation

Organization

More

Select best configuration for those interests
