NetBackup Accelerator Fundamentals



Problem: Increased data growth leads to missed backup windows.

NetBackup Accelerator Benefit: Reduce traditional full backups to the speed and cost of incremental backups so the most demanding SLAs can be met.

New Features: • Acceleration of backup; files and folders • Eliminate the need to read entire set of files over and over during each full backup • Eliminate the need to walk-through entire file system during the backups

Components of NetBackup Accelerator

• Track log

• Records information on files included in backup including checksum for segments

• Created for each policy and each file list entry in the policy

• Entries in track log and track log itself are also protected using checksums

• Eliminate the need to walk-through each file during backups

• Client OS and file system independent

• File System Change Journal (optional)

• Further enhances performance by making use of change journal built into file systems

• Currently supported only for Windows NTFS

NetBackup Client

• Inline Optimized Synthesis

• Zero data movement for segments already present in storage

• Optimized Synthetics occurs inline with backups, no post-backup processing

• Storage that supports Optimized Synthetics

• NetBackup Intelligent Deduplication Pools (MSDP & PDDO)

• NetBackup appliances (5000 and 5200 series)

• NetBackup CloudStore (Nirvanix, AT&T Synaptic, RackSpace, Amazon)

• Third party OpenStorage devices*

Client Track Log Files

The client track logs are key aspects of NetBackup Accelerator:

• The track log is specific for a given policy, client, master server, storage server, and backup selection.

• The NetBackup client track logs are circular files.

• The client track logs contain checksum entries for each file being backed up.



The NTFS change journal

• Is an optional feature that can be used with NetBackup Accelerator – Windows platform only

• Is monitored by NetBackup to determine which files and directories need to be included in a backup

• Eliminates the need to perform a full file system scan

• Maintains records pertaining to files and directories

• Has records identified by an update sequence number (USN)

• Are circular databases

• Is increased to one million entries



Additional NTFS change journal information

• Integration with the NTFS change journal does not guarantee that the NTFS change journal is used on every backup.

• The change journal data can be used with:

– Incremental backups: The Use accelerator option is enabled or not enabled.

– Full backups: The Use accelerator option is enabled.

• If the change journal data cannot be used for a backup:

– NetBackup reverts to a full file system scan.

– A message is logged in the Job Details dialog box for the backup.

NetBackup Accelerator and NetBackup Deduplication



Complimentary Technologies, Better Together

• Faster Backups

• Elimination of walking through all files at source

• Send only changed data to storage

• Eliminate sending redundant data in backups

• Functions across clients

• Encrypt backup streams at source for secure transmission

NetBackup Accelerator NetBackup Client Side Dedupe

NetBackup Accelerator and NetBackup Client Side Deduplication are complimentary technologies and work together on the same client to bring benefits from both features

From pricing perspective, both are available in the same SKU thereby helping customers realize the value of both technologies together for one price



NetBackup Accelerator NetBackup Client Side Deduplication

Supported on all client platforms with the exception of OpenVMS

Supported on major client platforms, please check NetBackup OS compatibility matrix

Supported on all file systems Supported file systems where OS is also supported

NetBackup Accelerator and Client Side Deduplication when used together provides global deduplication at the source while also speeding up full backups to the same level

as incremental backups.

Unstructured Data (Files and Folders) Backup

Target these use cases

Backing up file systems, especially the ones with less than 10% daily changes

Backing up NAS devices through NFS/CIFS*

Backing up clients at remote offices over WAN

Customers currently using incremental forever strategy to meet SLA



NetBackup Accelerator NetBackup Client Direct

Applications and databases not supported in this release.

Supported on major client platforms, please check NetBackup OS compatibility matrix

Supported on major applications and databases, Please check NetBackup Database Compatibility matrix.

Application and Database Backup


Backing up databases and applications through LAN

Backing up databases and applications in remote offices through WAN



NetBackup Accelerator NetBackup Side Deduplication

Run full backups at the speed of incremental backups. When file list changes or new clients get added the next full backup is not accelerated.

Data reduction irrespective of changes to file list or addition of new clients because of deduplication across all clients right at the source

Provides in-flight and at-rest encryption for backups

The ideal solution for remote offices/branch offices is to use the combination of NetBackup Accelerator and Client Side Deduplication to send only changed and deduplicated data that can be encrypted at source for secure transmission. Further, the combined solution provides support for databases and applications at ROBO

Remote Office/Branch Office Backup



NetBackup Accelerator NetBackup Client Direct

Not supported for VMware VADP Backup Hosts and Hyper-V VSS Backup Hosts at this time

Supported for VMware VADP Backup Hosts and Hyper-V VSS backup hosts

Recommend the combination of NetBackup Accelerator and NetBackup Client Direct for in-guest backups for RedHat KVM, IBM PowerVM, Citrix XenServer, Solaris whole root zones etc.

Backing up Virtualized Environments


VMware and Hyper-V: NetBackup Client Side Dededuplcation on backup hosts

All other hypervisors: NetBackup Client in guest OS with NetBackup Accelerator and NetBackup Client Side Dedupe



NetBackup Accelerator vs. Optimized Synthetic Backup with Dedicated Schedule

NetBackup Accelerator Optimized synthetic backup with dedicated schdule

Configuration As part of full backup Need separate synthetic backup schedule

Support multi-streaming Same as regular backup 1. Need an initial full 2. Issues with ALL_LOCAL_DRIVE or dynamic

streams during incremental backup 3. Adding new client during incremental backup

Work with change journal Yes No

NetBackup Catalog efficiency

1. Inc catalog for inc backup 2. Transfer only inc change for full backup

Need full (TIR+)catalog for incremental backups

NetBackup Catalog structure

The same as regular backup File directory structure becomes scattered over time and makes file & folder restore difficult

Build for incremental forever

1. Improved file change detection 2. Built-in backup image checksum validation

Future extensibility 1. VMware BCT support 2. Oracle Incremental merge 3. MS SQL change tracking 4. NDMP with forever incremental 5. VxFS or other FS with BLI support

not easily extensible beyond file & folders


Bottom line: If NetBackup Accelerator is purchased, there is no need to use Opt Synthetic backups with dedicated schedules


NetBackup Accelerator: NetBackup Appliances and Third Party Dedupe Appliances



Accelerator Pricing and Licensing

• In order to provide NetBackup Accelerator support for all customers, both NetBackup Accelerator and NetBackup Intelligent Deduplication are sold using a common container SKU named NetBackup Data Protection Optimization Add-on/Option. Both features are turned on with this license, although it is optional to use NetBackup Intelligent Deduplication if the customer already has other backup storage that supports NetBackup Accelerator. Note that Data Protection Optimization Add-on/Option is not a feature name; it is just the name of the SKU that enables two features.

• Customers using former NetBackup Deduplication Option licenses are automatically entitled to use both NetBackup Intelligent Deduplication and NetBackup Accelerator features.



Symantec Competitive differentiation: Pricing

NetBackup Accelerator + NetBackup Intelligent Dedupe

• Both are included in the same SKU, the customer gets both Accelerator and NetBackup Intelligent Deduplication from the same price per FETB

• Single-pane-of-glass management = low operating costs

NetBackup Accelerator +

3rd Party OpenStorage devices*

• Devalues Third Party OpenStorage devices as most of the data reduction is already done by NetBackup Accelerator

• Devalues Third Party OpenStorage devices as NetBackup Intelligent Dedupe is already included in the SKU for Accelerator for the same price

• Multiple management interfaces = high operating costs



Symantec Competitive Differentiation: Functional


NetBackup Intelligent Dedupe

• Performs a full backup in the time it takes to do an incremental backup

• Recovers with the speed of a full backup

• Global deduplication across all clients right at the source

• Directly write to storage bypassing media servers in the data path thereby bringing scale-out performance

• Encrypt at source for secure transmission to storage (remote office backups)


3rd Party OpenStorage devices*

• Performs a full backup in the time it takes to do an incremental backup

• Recovers with the speed of a full backup

• Limited ROBO support**
