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
![Page 6: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/6.jpg)
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
![Page 7: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/7.jpg)
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
![Page 10: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/10.jpg)
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
![Page 11: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/11.jpg)
Repository Options
v6 includes deduplication enhancement for repository
![Page 12: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/12.jpg)
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
![Page 13: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/13.jpg)
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
![Page 16: Veeam Backup & Replication presentationgo.veeam.com/rs/veeam/images/webinar_replay_rick_vanover... · 2020. 6. 12. · Compression and deduplication With Veeam: These go well together](https://reader035.vdocuments.mx/reader035/viewer/2022063019/5fddedcd9e052a5b6541c7f7/html5/thumbnails/16.jpg)
General recommendation
Examine data profile
Tweak job options to best meet all needs
Performance
Storage allocation
Organization
More
Select best configuration for those interests
