With more and more companies adopting virtualisation technologies organisations need to protect both virtual and physical environments with a single backup tool. It makes sense to use a solution that provides granular recovery from a single pass backup, saving time, money and any amount of effort – don’t use separate tools, it turns the recovery process into a nightmare! Optimising storage to reduce overall storage capacity can be done through integrated archiving and deduplication. Archiving moves old data to a separate store so you don’t have to backup the same data day-in, day-out – forever. Deduplication only backs up data (at a block level) once, using a pointer to the unique data. You can reduce the backup window dramatically with both archiving and data deduplication. The protection of Microsoft Applications is an inherently challenging process that becomes more difficult as the databases grow and the demands on its online availability increases, further limiting the time available for backup and recovery operations. Granular Recovery of Exchange, SQL and Active Directory from a single pass backup makes it easy and efficient to identify and recover only those objects needed. Help is at hand with the new, modern Backup Exec range designed to adapt for any business to easily protect increasing amounts of data, whatever the environment, while reducing storage and management costs through integrated deduplication and archiving technology. You can use this Blueprint to better understand Backup Exec's deduplication technologoe and the Deduplication Option.

Notice
This Backup Exec Blueprint presentation includes example diagrams that contain objects
that represent applications and platforms from other companies such as Microsoft and
VMware. These diagrams may or may not match or resemble actual implementations
found in end user environments. Any likeness or similarity to actual end user
environments is completely by coincidence.
The goal of the diagrams included in this blueprint presentation is not to recommend
specific ways in which to implement applications and platforms from other companies
such as Microsoft and VMware, but rather to illustrate Backup Exec best practices only.
For guidelines and best practices on installing and configuring applications and
platforms from other companies, please refer to best practice documentation and other
resources provided by those companies.

Backup Exec Client Deduplication - High-level Best Practices
At least of 1.5GB of physical memory on each protected client for client
side deduplication
Each protected client should have at least 1 dual core processor
Expect at least 75% CPU utilization during backup operation

11. Symantec Backup Exec Blueprints 11
Backup Exec Blueprints: Deduplication
Client deduplication use case recommendations
• Client Deduplication Can Simplify Remote Office Protection
• Scenario 1: Direct Backup
– Backups transmitted from remote office servers to Backup Exec server at
central location
– Remote office servers use Client Deduplication
• Scenario 2: “Store and Forward”
– Backups stored to Backup Exec server at remote office
– Deduplicated blocks transferred from remote office Backup Exec server
to central Backup Exec server
– Remote office Backup Exec server acts as “client” to central Backup Exec
server
– Requires CASO

12. Symantec Backup Exec Blueprints 12
Backup Exec Blueprints: Deduplication
Appliance deduplication use case recommendations
• Some Customers Have Invested in Deduplication Appliances
• Appliance Deduplication Can Be Leveraged
– Deduplication appliance handles all aspects of deduplication
– Requires OST plug-in
• Enables Intelligent Replication Tracking
– Backup Exec server tracks deduplicated backup data replicated to
additional deduplication appliances
– Can restore from replication target appliances

13. Symantec Backup Exec Blueprints 13
Backup Exec Blueprints: Deduplication
Tape recommendations
• Server and Client Deduplication Backups Stored to Disk First
• Can Be Copied to Tape Devices
– Just add tape stage in backup workflow
• Deduplicated Data “Rehydrated” Before Being Stored to Tape
– “Rehydrated” = restoring original data from deduplicated blocks
Backup Exec ServerProtected Client
Tape Device
Data is “rehydrated” before it is
transferred to tape

14. Symantec Backup Exec Blueprints 14
Backup Exec Blueprints: Deduplication
Disk recommendations
• Symantec recommends the following as minimum disk speeds
per individual read, write, or verify operation:
– Up to 32 TBs of storage:
• 130 MB per second
• 200 MB per second for enterprise-level performance
• 32 to 48 TBs of storage: 200 MB per second
• 48 to 64 TBs of storage: 250 MB per second
• The above recommendations are for the performance of a
single operation. You may need more capability depending on
your objectives for writing to and reading from disk.
Note: You should be aware of the effects that computer disk speeds have on
deduplication performance.

also located in the same remote office, in conjunction with the use of Optimized Duplication to copy deduplicated backup data from
the remote Backup Exec server to a Backup Exec server at a central office location.

Best Practices: Deduplication
Do the following…
• Deduplication Database Sizing
– Roughly 6-8 GB of database size per 1 TB of stored deduplicated data.
– Maintenance routines make a backup copy of the database
– Additional space required for database backup copy
– Use a dynamic volume that can grow as needed
• Processor Utilization
– At least 75% processor utilization for that processor core for the duration
– Minimum: Backup Exec server should have at least one four cores processor;
(for 64 TB of stored deduplicated data, 8 cores are required)
– Recommended: 8 cores
• Agent for VMware and Hyper-V
– Image-level backups of VMware virtual machines require server deduplication

20. Symantec Backup Exec Blueprints 20
Best Practices: Deduplication
Do the following…
• Physical Memory on Backup Exec Server
– 8 GB of free physical system RAM for up to 5 TB of deduplicated data
– For more than 5 TB of data, use the following:
• 1.5 GB x N, where N = the number of TBs of deduplicated data to be stored
• Physical Memory on Client
– 1.5 GB of free physical memory on each client that uses client
• Use Dedicated Logon Account for Deduplication Disk Device
• Changing Backup Exec Logon Account Password
– If you change Backup Exec logon account password, use the spauser.exe
utility to update it

21. Do not…

22. Symantec Backup Exec Blueprints 22
Best Practices: Deduplication
Do not do the following…
• RAID Caching
– Do not enable RAID caching on disk hosting deduplication disk storage device
• Verifying Backups
– Verify with the duplication job
• Client Deduplication
– Do not use client deduplication if remote system has heavy processing load;
use server-side deduplication
• WAN Considerations
– Do not use server deduplication with backups over WAN
– Remote office protection without local storage should use client
deduplication
• You cannot create a deduplication storage folder in a storage path
that contains double-byte characters
