TOP REASONS TO CHOOSE DELL EMC
OVER VERITAS NETBACKUP®
1
DELL EMC HAS THE MOST EFFICIENT DEDUPLICATION
ON THE MARKET
EMC Data Domain was designed from the ground up with data deduplication and data
protection in mind. Deduplication is not a bolt-on to a tape- centric solution. Therefore,
Data Domain does not suffer from the performance and scale limitations that bolt-on
architectures have. This translates into less infrastructure needed to support
performance and retention SLAs.
With Data Domain’s superior deduplication, costs and bandwidth usage are reduced
and it provides a tremendous impact at scale.
Veritas Appliances do not use global dedupe. You cannot pool them and you cannot
dedupe against them. Instead, you must create multiple “islands” of deduplication;
therefore decreasing efficiency.
Customers have found the NetBackup Database will grow significantly with the
combined use of deduplication and NetBackup Accelerator. The clients may also
experience growth due to the track log. And this in turns compounds the difficulty of
Disaster Recovery.
On average, Veritas customers require 3x the amount of storage. Data Domain’s high
speed, variable length deduplication reduces storage requirements by 10 to 30x. At
these ratios, this is a huge storage savings.
Veritas uses fixed-length deduplication, which is less efficient.
Veritas NetBackup uses “limited stream handlers” in an effort to improve their poor
deduplication. It is only supported for a few workloads such as file backup, NetApp
NDMP, VMware, and Hyper-V.
EMC Data Domain is plug’n play; NetBackup deduplication requires weeks planning
and extensive roll out windows with NetBackup’s most complex features, the 14 step
program. Synthetics, SAN Client, Stream handlers with no sizing or guidance, roll your
own which causes architecture bloat post sale.

EMC DD BOOST FOR ENTERPRISE APPLICATIONS
(DDBEA)
Modules for using EMC DD Boost together with native data protection functionality from:
•
SAP HANA
•
SAP with Oracle (BR*Tools)
•
Oracle (RMAN)
•
Microsoft SQL
•
IBM DB2
EMC Data Protection Advisor (DPA) for monitoring and reporting on the various
sources.
HANDOUT
These modules allow application administrators (DBAs) to work with their own
interfaces and workflows, yet still move data to protection storage in an efficient
manner.
This means that instead of having to install third party backup software and giving
another team the control over scheduling and workflow, the DBAs now control, when
and if they protect their data.
In some applications they even stay in control of moving this data offsite, simply
specifying that the DataDomain target should perform what is known as a Managed File
Replication to one (or more) DataDomain system(s). Recovery of the data can take
place from any of these systems.
For some of the systems, replication can be controlled by writing to different folders in
the DataDomain system, if they write to one that is enabled for DataDomain mtree
replication, the data is moved offsite as soon as the backup is done, write to one where
it isn’t and data stays onsite.
The whole point of developing this functionality is that in many organizations, there is a
rift opening up between what application owners demand and require and what the IT
operations department can deliver. Eventually, you see everyone rolling their own
solutions and creating the dreaded silos that breed cost, complexity and poor
interoperability.
The figure below shows how simple the DDBEA deployment design is compared to Veritas’s
Copilot deployment design. DDBEA has native direct application to Protection Storage design
keeping deployment and operational costs to a minimum.
DD Boost for Enterprise Applications addresses one of these rift creating scenarios,
namely the classic problem that DBA’s does not want someone else to interfere with
their often very complex environments, in this case through traditional backup and
recovery backup application’s.
NetBackup’s Copilot
Copilot should not be compared to DDBEA as DDBEA is a native RMAN backup utiluity
to which DBA’s are accustomed to using. A more accurate comparison would be
NetWorker and NetBackup. The NetBackup Copilot feature requires Backup admins
and DBA to work on integrating the solution. DDBEA writes directly to deduplicated
storage where a NetBackup appliance is carved to use Advanced Disk for initial dump
and a postscript process to update the NetBackup and RMAN catalogs. EMC Data
Doman has supported all the competitor options and has since 2011.
The figure below shows how how Veritas’s Copilot deployment is. It is a post-process non native
integration method. The Database is dumped to the non deduplicable storage and then Veritas
scans that dump and after copies to a deduplicable like storage. Its design is much more
complicated than a Dell EMC solution. In addition, there’s no optimized data transfer like DD Boost
and no advanced feature support like Oracle multiplexing, Veritas has marketed the Copilot feature
as game changing for their users but in fact it is very simplistic and something we’ve actually
supported with NetWorker for several years already.

DELL EMC HAS SUPERIOR PROTECTION
CAPABILITIES IN A VIRTUAL ENVIRONMENT
The Data Protection Suite Family supports not only change block tracking backup, but
also change block tracking restore.
With the Data Protection Suite Family’s Instant Access capabilities, an image can be
accessed instantly and run from the Data Domain system. This provides the end user
access during a critical time period when the end user cannot wait (even a few minutes)
for a restore back to the production environment.
Veritas NetBackup proposes using the SAN Transport Type Method of backing up
VMware that involves using the SAN and FC rather than IP. Veritas claims this
improves performance however; this is costly due to FC connectivity and the physical
servers needed. It is also risky because SAN Zoning is the only security and the proxy
needs full access to ALL virtual machine (VM) datastores, meaning datastores can
accidently get corrupted and/or deleted. Avamar uses virtual, auto-load balancing
proxies requiring no additional configuration or management to protect VMware.
To scale your virtual environment in a NetBackup environment requires adding physical
NetBackup 5230’s or 5330’s or physical media servers to scale the number of
simultaneous snaps. Dell EMC leverages lightweight virtual proxies to allow customers
to easily and dynamically scale the number of simultaneous snaps and backup streams
needed to meet their backup windows. Dell EMC follows VMware best practices to
enable fast and efficient backups that are done at the hypervisor level. The value to this
approach is that it allows the customer to determine how and where to run their work
loads.
Veritas NetBackup provides V-Ray which allows scanning of the VMDK’s for image and
file level recovery in one pass. However, Dell EMC is the industry leader with VMware
integration and first to market with this technology over two years ago.
Veritas NetBackup offers a feature called Virtual Machine Intelligent Policy (VIP) which
enables auto- detection for new, moved or cloned VM’s for automatic backups. The
reality of using this feature is that it requires knowledge of SQL scripting and debugging
any time changes are made to the VM environment. There can be a certain degree of
risk in missing VM’s for backup due to scripting error/oversight. VIP is also known to be
slow and complex, and it needs to be scheduled to run periodically. Dell EMC does this
automatically without any configuration using its tight integration with vCenter.
EMC Data Protection Advisor’s integration with VMware enables the tracking of
performance, resource consumption, data protection, and conflicting backup job
schedules, as well as movement of host images between VMware systems. Data
Protection Advisor tracks virtual data movement with assigned protection policies—for
both backup and replication—to provide confidence that virtualized mission-critical
applications are protected.

THE EMC DATA PROTECTION SUITE FAMILY OFFERS
SUPERIOR DATA DOMAIN INTEGRATION
The Data Protection Suite Family can leverage Data Domain Boost (DD Boost) for
backups. Parts of the deduplication process are distributed to the backup or application
server to reduce network utilization and remove media servers from the data path to
reduce costs/improve performance. This reduces proxy resource usage by 20-40%,
improves Data Domain ingest rates by 50%, and reduces LAN link usage by 80-99%
during backups.
DD Boost integration enables the Data Protection Suite Family to support a larger
environment with less infrastructure when using Data Domain protection storage.
Through a single management point, you can configure Data Domain for backup with
the backup admin's interface. It also reports on the state of the Data Domain system.
The Data Protection Suite Family has the ability to use the standard cloning process to
control the Data Domain replication process with Clone Controlled Replication. Backup
admins can use a standard tool to manage the process and let Data Domain manage
the data movement. Both the backup and the replication are managed via the catalog.
To do this with NetBackup, SLP’s are required. There is no ability of applying a
schedule such that the replication can be done at a certain time and the whole process
must work or it will have to be started from the beginning.
5
The Data Protection Suite Family offers synthetic/virtual full Backups that allows you to
maintain a current full backup on the Data Domain system using a series of incremental
backups. This capability saves storage and bandwidth and increases the speed of the
backup.
DELL EMC DELIVERS ADVANCED MONITORING,
ANALYSIS, AND REPORTING OF THE BACKUP
ENVIRONMENT
The Data Protection Suite Family provides a comprehensive set of monitoring, analysis,
and reporting capabilities that are excellent, especially when compared to Veritas
NetBackup.
Data Protection Advisor supports many backup products; including all Dell EMC backup
products, as well as Veritas NetBackup, Backup Exec, IBM Tivoli Storage Manager, HP
Data Protector, CA Arcserve, Oracle RMAN, CommVault Simpana, Physical Tape
Library, VTL, and VMware VDP.
With such broad backup coverage, DPA can manage without vendor lock-in of Veritas
NetBackup.
Veritas NetBackup’s OpsCenter only reports on its own software and hardware. With
EMC Data Protection Advisor, you’ll be able to unify and automate monitoring, analysis,
and reporting across data protection environments while reducing complexity, lowering
costs, and eliminating manual efforts.
You generally need a minimum of 3 main consoles to manage a Veritas environment
(NBU Java/Win Admin Console, NBU Appliance Console, and OpsCenter). They look
nothing alike and have zero integration across them. Also, OpsCenter and the NBU
Appliance Console have nothing comparable to Data Domain Management Center in
terms of centralized management of multiple Appliances.
OpsCenter has a very basic dashboard for some hardware alerts and there’s no
centralized management of NetBackup Appliances.

DELL EMC PROVIDES SUPERIOR DEFENSE AGAINST
DATA INTEGRITY ISSUES
EMC Data Domain Data Invulnerability Architecture provides the industry’s best
defense against
data integrity issues through inline write and read verification,
continuous fault detection,
and self-healing to ensure there is no corruption during
the backup process- a unique differentiator.
Data Domain Data Invulnerability Architecture includes a self-healing file system, which
continuously "checks" the protection data stream for errors and corrects them. The
customer is assured that critical data is protected, recoverable, accessible, and not
corrupted.
This is critically important as data-loss in a dedupe environment is much more impactful.
NetBackup Appliances do not provide continuous data integrity checking.
The dedupe engine from Veritas doesn’t have anything equivalent to the DD filesystem
and the SISL Invulnerability Architecture. Instead, it relies on replication only for its data
availability. Logically, for every NetBackup Appliance you purchase, you’ll also need to
purchase a “mirror NetBackup Appliance” to replicate the data to in order to provide a
higher level of availability. That scenario provides better protection than any single
NetBackup Appliance can provide but it is still not equivalent to the protection we offer
with DIA.
7
DELL EMC PROVIDES SNAPSHOT MANAGEMENT
Dell EMC data protection solutions deliver end-to-end data protection and recovery for
environments that require snapshot backup functionality that makes tracking and
restoring snapshot backups simple by cataloging the snapshots from multiple arrays
and array types.
Dell EMC offers intelligent pairing for VMAX which automatically identifies an available
LUN to synchronize with a specified source LUN.
Dell EMC provides snapshot management retention policies that manages the lifecycles
of the snapshot savesets.
Dell EMC offers cradle to grave management of the snapshot and the backup process
which includes configuration, management, reporting, backup, replication and recovery
of snapshots.
The ability to catalogue/index/discover snaps not created by NetWorker is a
differentiator unique to Networker; NetBackup does not have this capability.
NetWorker supports more application types vs. NetBackup Replication Director, such as
DB2, Oracle and SAP with Oracle.
Networker supports more arrays/ platforms than NetBackup Replication Director.
Veritas provides Replication Director which manages snapshots but is a very “NetAppcentric” solution whereas Dell EMC supports EMC block arrays, EMC NAS Filers, VNX,
NetApp and RecoverPoint.
In fact, many of the snapshot features they support are only supported on NetApp
devices.

EMC PROTECTPOINT DELIVERS INDUSTRY-LEADING
PROTECTION STORAGE WITH PRIMARY STORAGE
Not only is Dell EMC delivering world class deduplication and backup software solutions
Dell EMC is now leading the industry with eliminating resource impact on application
hosts.
Eliminates backup impact on the application by removing the server from the data path
and minimizing the traditional backup window.
ProtectPoint provides the performance of snapshots and the functionality of backups
while protecting mission critical data on industry leading protection storage.
Reliable Protection ensure recovery with the industry’s best defense against data
integrity issues.

DELL EMC HELPS YOU MEET RECOVERY TIME
OBJECTIVES (RTO)
With the Data Protection Suite Family, there is no need to search the tapes to recover a
file. All backups are full backups ensuring efficient recovery, and recovery is sent
compressed.
10
DELL EMC DISASTER RECOVERY (DR) IS MUCH
EASIER WITH LESS RISK
With Dell EMC data protection solutions, customers can replicate backup and archive
data off-site faster and reduce bandwidth requirements by 99% for safe, efficient
disaster recovery.
The Data Protection Suite Family provides backup and restore awareness across sites
utilizing clone awareness and a tight integration with Data Domain.
NetBackup Automated Image Replication (A.I.R.) was never meant to be a complete
site wide DR solution for Veritas customers. It was only meant to be a site to site, or
NBU domain to NBU domain or Cloud, replication of small amounts of customer’s
mission critical data only. There is no automated method to restore backups directly
from the target domain to clients in the source domain. A.I.R. is not catalog replication
and it can’t replicate pre-existing backup image data.
Also, at the primary site, there is no control of the duplicated copy after it has been sent
to the DR site. It could be lost, moved or deleted without you being aware and it can
only be fully managed from the DR site- so there’s an element of risk and uncertainty.
A.I.R. does not provide the comprehensive DR solution that Dell EMC does. In most
cases NetBackup recommends to replicate outside normal backup windows. This
drastically changes customers Recovery Time Objective (RTO). As data lands on a
Data Domain system, it will immediately begin replicating it to a DR site. To meet strict
DR requirements, EMC Data Domain Replicator software can replicate at 52 TB/hr over
a 10 GB network connection. Data Domain systems only replicate unique compressed
data across the network, requiring a fraction of the time, bandwidth and cost of
traditional replication methods. This can reduce WAN bandwidth requirements up to
99%, making network-based replication fast, reliable and cost-effective. For the highest
level of security, data being replicated between Data Domain systems can be encrypted
by using the standard Secure Socket Layer (SSL) protocol. Data Domain systems
provide flexible replication topologies including full system mirroring, bi-directional,
many-to-one, one-to- many, and cascaded. In a many-to-one deployment, data from up
to 540 remote offices can be replicated to a single Data Domain DD9500 system.

DELL EMC LEADS THE INDUSTRY IN PROVIDING
PARTNERS, RESELLERS AND SERVICE PROVIDERS
RESTFUL WEB SERVICES
RESTful services offer the benefits of a modern open interface in a robust fashion.
Unlike CLI and CLI scripting, the REST API is designed to maintain backwards
compatibility in future releases. Dell EMC software solutions are exposing their
software using REST for customers and partners to enable, Custom reporting,
automation of management services, integration to existing management platforms etc.
12
THE EMC DATA PROTECTION SUITE FAMILY IS
CLOUD-ENABLED
EMC CloudBoost is cloud-enabling technology that facilitates secure, automatic,
efficient long-term retention of backups in private or public cloud. CloudBoost eliminates
the risks of tape, reduces cost, and increases IT and business agility by extending the
reach of the Data Protection Suite Family to resilient, hyper-scalable cloud storage.
Veritas offers support for Cloud based platforms using their NetBackup Appliances as
gateways. However, the weaknesses and inefficiencies of their appliances actually puts
NetBackups customers data at risk and results in a higher Total Cost of Operation.
In addition to improving performance and scalability, CloudBoost’s split-plane
architecture separates data from metadata, enabling native support for a wide range of
object stores. Private clouds supported by CloudBoost include EMC Elastic Cloud
Storage (ECS), EMC Atmos, and OpenStack Swift. Public clouds supported by
CloudBoost include AT&T Synaptic, Amazon Web Services S3, Google Cloud Storage
(including Nearline), and Microsoft Azure.
