 Overall features
For each feature, we provide a detailed ranking of the products and we explain the
rankings when they’re dissimilar.
The next feature chart reveals how well CA ARCserve and Simpana 9 fare in producing
– and recovering from – image-based backups.
Image-based Backup
An image-based full system backup contains everything about a computer at the
moment the backup copy was made – the operating system, the system’s current state
and the data file disk blocks. The backed up image can later be restored (termed a Bare
Metal Restore operation, or BMR) either to the same computer or to another computer
of different brand and type. Additionally, image-based backup products offer granular
recovery at the application and file level for faster recovery.

Image-based Backup Notes
Technology – CA ARCserve r16 offers true infinite incremental snapshot/image-based
backups onto virtually any disk drive. CA ARCserve’s image-based backup/restore
component is easy to install, a breeze to use, relatively inexpensive to buy and highly
protective of your data. CA ARCserve’s disk-to-disk image-based backup supports
myriads of hardware combinations.
CA ARCserve’s image-based backup is built on its patent-pending Infinite Incremental
(I2 Technology) that enables users to only perform a full backup once (the first time it’s
used) and then only perform incremental backups from that point forward. This
technology has been designed to intelligently manage the backup of only blocks of data
that have changed since the last backup and present a consolidated point-in-time view
of the protected volume for multiple recovery types, thus reducing your recovery time.
Both CA ARCserve and Simpana offer synthetic backups, in which a full backup is
assembled, or synthesized, from a baseline full backup and subsequent incremental
backups. Simpana users must periodically create a new full backup. CA ARCserve’s I2,
on the other hand, does not have this limitation – hence the name Infinite Incremental.
Simpana’s design of its synthetic full backup methodology uses what the vendor terms
Deduplication Accelerated Streaming Hash (DASH) to reduce the time needed for
synthetic full backup operation. To minimize disk I/O, DASH transfers only data
signatures instead of actual data to the target.
We were deeply disappointed by CommVault’s disk image processing module,
SnapProtect. It’s difficult and time-consuming to install, it’s expensive and – the worst
part – it’s engineered poorly when it comes to protecting your data. CommVault admits
that installing SnapProtect requires 4 weeks of effort. CommVault also says you’ll need
to research and either update or adjust several environment details: Firmware versions
on the array, device types, modes of access, security configurations, operating systems
that access the storage array and application layout on the storage array LUNs.
SnapProtect can record hardware-based snapshots onto (within) just Dell, EMC HDS,
HP, IBM or NetApp hardware arrays.
SnapProtect writes its backup/snapshot file (your first line of data disaster defense)
onto the same hardware array filesystem that you’re afraid may fail. Later, the
CommCell’s CommServer schedules a subsequent operation to tell a proxy server to
mount the hardware array, copy the image files to secondary storage and, after the
secondary file copy finishes, unmount the hardware array. SnapProtect itself merely
halts the application, triggers the hardware array to produce a snapshot right within the
array and then restarts the application. We find these extra operations and steps to be a
risky and poorly-designed engineering approach to protecting critical data.

Review
CommVault imposes a number of other limitations and restrictions on SnapProtect.
These include but are not limited to:

Once a backup copy is performed and the snapshot is copied to media, the same
snapshot cannot be re-copied again

If a previously selected snapshot has not been copied to media, the current
SnapProtect job will complete without creating the backup copy and you will need
to create an offline backup copy for the current backup

If the Storage Policy or the disk library being used by the subclient is updated,
the subclient should be recreated

SnapProtect backups support online virtual machines only with NetApp file
servers. Other storage array vendors use the traditional backup method. To
perform a SnapProtect backup, the virtual machine must be offline.
CA ARCserve r16 and Simpana 9 can each create snapshots as often as every 15
minutes.
Operating Systems, BMR – Simpana supports UNIX flavors as well as Windows, but
CA ARCserve supports only Windows. Simpana, like CA ARCserve, can restore
Windows images onto dissimilar hardware, but imposes significant constraints on its
UNIX BMR operations.
Cloud Support – Both Simpana and CA ARCserve write the initial snapshot (backup)
to disk. A subsequent step copies the snapshot data to a cloud. For secondary storage
(via its proxy backup/restore component), Simpana 9 can interface with the cloud
vendors Amazon, Azure, EMC (Atmos), Iron Mountain, Meseo, Nirvanix and
Rackspace. CA ARCserve’s D2D feature works with Amazon and Azure to store
secondary or tertiary image backups. After the first image copy to the cloud, CA
ARCserve transmits only incremental changes (via I2) from that point forward. This
makes the best use of low-speed cloud connections.
Remote Management via Managed Service Providers (MSPs) – Several MSPs have
embraced CA ARCserve, and the list is growing. CommVault is currently just beginning
to get MSPs to consider supporting Simpana.

Performance and Media Usage – CA ARCserve’s I2 is faster than Simpana 9’s
synthetic full backup process (its Deduplication Accelerated Streaming Hash
notwithstanding), and I2 uses less storage space. For a complete system comprising
300 GB, Figure 1 shows the relative performance of CA ARCserve r16 I2 and Simpana
9.

CA ARCserve also needed 8% less storage space than Simpana 9 (120 GB vs. 131
GB) when we tested the creation of monthly full backups and selected each product’s
highest level of compression.
In our tests, CA ARCserve’s I2 utilized only small, incremental amounts of backup
storage after the initial full backup. In contrast, Simpana 9’s need to perform periodic full
backups caused it to consume considerable backup storage, overwhelming any
advantage of Simpana’s (interim) synthetic full backups.
Using infinite incrementals (one full backup at the outset and incremental thereafter) –
but telling Simpana 9 (as CommVault recommends) to continue creating monthly full
backups with incrementals during the month – we saw that I2 used about half Simpana’s
space at the end of two months (144 GB vs. 268 GB) and a little more than a third of
Simpana’s space at the end of three months (161 GB vs. 420 GB). Figure 2 depicts the
resulting storage requirements.

Virtualization Support -- Both CA ARCserve and Simpana 9 are champions of
virtualization, supporting VMware ESX and vSphere, Microsoft Hyper-V and Citrix
XenServer. CA ARCserve additionally supports Redhat KVM.
Virtual Standby – CA ARCserve offers Virtual Standby, a feature wherein up-to-date
copies of backup images (recovery points) are available for immediate use in case of a
system outage, thus offering near-instantaneous system recovery. CA ARCserve’s
Virtual Standby feature automatically converts recovery points into VMDK and VHD
formats and automatically registers with the hypervisor. It offers automated and manual
failover. Furthermore, CA ARCserve’s virtual standby works in either physical-to-virtual
(P2V) or virtual-to-virtual (V2V) failover modes.
Unfortunately, Simpana 9 lacks an automated virtual standby feature.

RTO/RPO Performance Testing – To measure CA ARCserve’s and Simpana’s
Recovery Time Objective (RTO) and Recovery Point Objective (RPO) performance, we
simulated the destruction of four Windows Server computers containing a total of 300
GB in a small data center. One of these computers ran SQL Server 2005, one ran
Internet Information Server (IIS), one ran an OLTP business application and the fourth
was the backup server. In our tests, both CA ARCserve and Simpana took snapshots
every fifteen minutes and transferred backup material to a remote location. Four
computers at the remote location stood by, waiting to go to work in case of a disaster.
We measured the minutes needed to recover data and resume operations.
Using CA ARCserve image-based backup in one test and Simpana in another test, an
administrator at the remote location restored the transferred data onto the waiting
secondary servers. The test concluded when the administrator had restored all servers
and had brought the OLTP application back online.
The CA ARCserve administrator needed just 47 minutes to restore data to the
servers and resume the OLTP application. Primarily because of the complexity of its
user interface (and despite its use of the term “1-Touch” to describe the process), the
Simpana administrator needed one hour and fifteen minutes (75 minutes) to
accomplish the same thing – 28 minutes longer. If time is money in your data center,
CA ARCserve is clearly the tool of choice when disaster strikes.
Central Management – Working with disk images is easy and painless with CA
ARCserve's Web 2.0 based management console. Simpana’s user interface for dealing
with image-based backups is comparatively awkward, despite its “1-Touch” name.
Central Reporting – Similarly, CA ARCserve’s Central Reporting component produces
much more useful and informative reports regarding disk image recovery points than
does Simpana 9. Both products integrate with Windows Explorer to show the contents
of an image file as a mountable drive letter.
In the next chart, we take a detailed look at basic, fundamental CA ARCserve r16 and
Simpana 9 file-based backup and restore capabilities.
File-based Backup
A file-based backup contains copies of applications and data files you designate, file by
file and directory by directory. The backup process automatically and regularly creates
the latest backup copy onto whatever media you specify – tape, disk, USB memory or
other device. You can archive older backup copies offsite, for safekeeping. Restoring
the data copies it back to the source machine or other computer that typically already

Review
Separately for each Storage Policy, Simpana’s basic reports show details on backup
histories, retentions and storage media usage. In contrast, CA ARCserve Central
Reporting provides global views, administration and reporting on all devices, settings
and policies (running on-premise and off-premise) protected by CA ARCserve. It gives
both detailed reports and a summary Dashboard report view that clearly show the
overall status as well as individual details for any and all backup operations.
With its reports on physical servers and the contents of individual VMs, file-level
analysis and physical resource consumption, Simpana 9 exhibits a modicum of SRM
capability. In stark contrast, CA ARCserve’s topology map clearly and intuitively
displays a customer's infrastructure. By node, virtual machine or device, CA ARCserve
graphically presents a hierarchical picture of data backup sets. CA ARCserve’s SRM
reporting is revealing, comprehensive and helpful. A person can monitor the status of
any and all backup operations, identify long-running backup operations, locate backed
up data, discover whether data is encrypted, know the company’s disaster recovery
status and track volume, disk and memory usage on each server.
Simpana 9 can perform data deduplication at either the server or the client, while CA
ARCserve’s deduplication is server-only. On the other hand, Simpana’s deduplication
feature is an extra-charge option. CA ARCserve includes deduplication at no extra
charge.
Also note that Simpana 9 has some quirky and somewhat confusing restrictions on the
use of incremental backups, as exemplified by the following Simpana 9 documentation
excerpt.
Incremental Storage Policy Considerations
 You cannot enable a storage policy as an incremental storage policy if that
storage policy already has an incremental storage policy enabled.
 The incremental storage policy option is only available for a Standard storage
policy.
 If you are using a different MediaAgent for an incremental storage policy than the
MediaAgent used for a full storage policy, one of the following conditions must be
met:
o The primary copies of both this storage policy and the selected incremental
storage policy use a shared index cache.
o The primary copies of both this storage policy and the selected incremental
storage policy are set to use preferred data paths.
 If an incremental storage policy is de-associated from a storage policy, the most
recent incremental backup may be pruned before the next full backup occurs.

In the last features table, let’s examine the huge differences between CA ARCserve and
Simpana 9 in the areas of replication and high availability.
Replication and High Availability
Replication continuously copies changes made to one (master) computer’s files to a
secondary (replica) computer. The replica computer is always an exact copy of the
master.
High Availability manages the relationship between the master and replica computers in
a way that makes the replica computer almost instantly assume the role of master if the
master computer suffers a problem.
Multiple master and replica computers are possible. The result is a file, application or
database server that’s virtually always available.

Replication and High Availability Notes
CA ARCserve’s replication component may be used in a scheduled manner to migrate
and manage offsite backups. In a real-time, continuous manner, CA ARCserve provides
true Continuous Data Protection (CDP). In contrast, Simpana’s replication feature,
Continuous Data Replication (CDR), delivers “Near CDP” by allowing disaster recovery
copies of backup/archive data to be created over a LAN or WAN on a continuous basis.
However, Simpana’s approach requires manual intervention on the part of an
administrator when a data disaster occurs.
For companies needing maximum system uptime and availability, CA ARCserve has a
High Availability (HA) component. Simpana 9 has a replication feature but does not offer
high availability.
Both CA ARCserve’s and Simpana’s replication components perform asynchronous
replication and support Windows, Linux and UNIX environments. They may be deployed
onsite, offsite and/or linked to a cloud. Basically, CA ARCserve’s and Simpana’s
replication features clone each I/O operation and send the cloned copy to a secondary
destination of your choice.
Both CA ARCserve and Simpana can replicate between physical and virtual servers
(P2P, P2V and V2P) and even between virtual server platforms (V2V).
CA ARCserve’s HA component includes all the functions of the replication component
and adds the ability to monitor one or more background services running on a server. If
a service fails, CA ARCserve will attempt to restart it. If the restart fails, the system can
be set to automatically fail over to the replica (or failover) server. Alternately, the
administrator can set the system to not automatically failover, thus allowing the
administrator to investigate the problem. The administrator can then choose to use
push-button failover. Simpana lacks all these features.

Review
With Simpana’s “Near CDP” and absence of a high availability component, you still run
the risk of significant outages and stoppages in the running of your business when you
need to recover data and start up replacement servers.
CA ARCserve can monitor a single server, group of servers, entire server farm or
specific applications, such as Microsoft Exchange, SQL Server, SharePoint, IIS and
Dynamics CRM, thus ensuring maximum availability. When a hardware or application
failure occurs, CA ARCserve automatically activates the replica server(s). It gives the
replica servers IP addresses and host names during activation to make failover
transparent to end users, many of whom will never even know an outage occurred.
Again, Simpana lacks these abilities.
CA ARCserve’s HA component is perfect for distributed applications like Microsoft
SharePoint and Dynamics CRM, which typically have a multi-tier architecture consisting
of separate Web, application and database servers. CA ARCserve replicates, monitors
and fails over all the servers, not just the database server. And with group management,
all component servers can be failed over even if only one fails. This is especially useful
when the replica servers are kept at a distant remote location. CA ARCserve offers
sophisticated push-button failover and failback for the highest possible level of
automated availability. Simpana’s replication feature requires that an administrator
manually start the application(s) that will access the replicated data.
CA ARCserve comes with many pre-built replication and high availability scenarios.
Furthermore, it provides application-aware replication and failover for Exchange, SQL
Server, SharePoint, and IIS, as well as Oracle and Blackberry. In other words, CA
ARCserve already knows what specific directories and files to replicate and when – you
just indicate which applications to protect. Simpana comes with far fewer pre-built
scenarios, and for just some of the most popular applications – Oracle, Microsoft
Exchange, Microsoft SharePoint and Microsoft SQL Server.
While both CA ARCserve and Simpana support virtual computing environments, CA
ARCserve’s HA component goes much further than Simpana. CA ARCserve offers high
availability for VMware vSphere, Microsoft Hyper-V and Citrix XenServer. Simpana can
perform replication in a VMware environment, but it does not have high availability
support for any of these virtual platforms.
CA ARCserve is also unique in its high availability support for Windows server clusters.
Simpana can replicate data onto clustered Windows servers, but an administrator must
activate servers within the cluster to complete/finish a failover operation.
CA ARCserve’s Replication and High Availability components also include an easy-touse assessment mode tool for performing “what if” dry runs to assure you have

adequate bandwidth for replication. CA ARCserve also offers an Assured Recovery
testing feature you can use to perform scheduled or ad-hoc recovery testing at the
application level on the replica server, without affecting the production server or
impacting the continuous data protection and monitoring. Simpana’s less automated
approach requires manual intervention and, unfortunately, requires rebooting the server.
Simply put, Simpana lacks CA ARCserve’s feature-rich, mature ability to replicate,
monitor and automatically fail over critical servers.
When we measured RTO/RPO by performing the same disaster recovery test with CA
ARCserve’s High Availability component that we’d done with CA ARCserve’s imagebased feature (*see RTO/RPO section above under Image-based Backup), CA
ARCserve needed just six seconds to automatically restart the OLTP application
at the remote backup site. Simpana’s replication feature required an interminable 93
seconds – over a minute and a half – to recover from the simulated disaster, after
which the administrator had to manually restart the OLTP application.
Ease of Use and Pricing
CA ARCserve’s well-formatted and configurable dashboard reveals, at a glance, the
current status of your backups. With Simpana, visualizing backup status requires
several more navigations steps. If you have multiple site backups, both CA ARCserve
and Simpana consolidate and centralize backup status information from all sites.
Simpana also shows a dashboard display of backup/restore status information, but it’s
not as revealing nor as configurable as CA ARCserve’s.
Note that one of the Simpana dashboard indicators gives you an at-a-glance reminder
of how much of your Simpana licensed capacity you’re using. If you exceed that
licensed capacity, even for just a moment, the Simpana software “phones home” to
notify CommVault of the “excess usage.” You see the result in a bill from CommVault,
and the size of the bill may astonish you … CommVault’s charges for excess usage are
quite high.
We were also disappointed and dismayed to find that CommVault, both in its
documentation and in its approach to data protection, considers “disaster recovery” to
be the restoration of a failed Simpana server rather than the recovery of a customer’s
critical data. To our minds (and perhaps to yours), this is the wrong perspective.
Data visibility is crucial to data backup reliability. With a single click, CA ARCserve
displays a clear and highly descriptive graphical view of backup sets and backed up
data. In contrast, navigating Simpana's Storage Policy-oriented backup reports can be
time-consuming and unproductive. Furthermore, Simpana gave us an unpleasant

surprise by requiring us to periodically reorganize and re-index each of the internal
CommCell databases.
CA ARCserve’s image-based backup component has a Web 2.0 interface that provides
real-time access to the latest documentation updates, invaluable technical data, helpful
tips and online user communities. Impressively, CA ARCserve’s Web 2.0 interface even
gives customers virtually direct access to the CA ARCserve development staff – and
they actually listen to customer suggestions and ideas. Simpana’s user interface, which
is not intuitive and which requires much more user input to accomplish the same tasks,
pales in comparison.
CA ARCserve’s Web 2.0 interface has meaningful icons, a grasp-at-first-glance view of
network objects and pop-up windows for object-specific tasks. It strategically uses multilevel drop-down menus and tabs to organize tasks in a way that aligns perfectly with a
network administrator's workflow. Every backup and restore operation is within easy
reach of just a few mouse clicks.
CA ARCserve makes extensive use of the Ajax (Asynchronous JavaScript and XML)
multipurpose browser-based framework of tools, widgets, controls and methods. CA
ARCserve’s interface offers a rich set of widgets that resemble elements of native
desktop applications. For example, it has built-in support for keyboard navigation, focus
and tab handling and drag & drop.
CA ARCserve’s Web 2.0 interface gave us the ability to remotely access all our
protected servers, change configuration settings, check the status of our backups and
restores, initiate backup jobs and launch remote recoveries – all via the Internet.
CommVault’s pricing for Simpana 9 is significantly higher than that of CA ARCserve, as
shown in the following tables. (Except for the managed capacity offerings, CA
ARCserve pricing includes one year of maintenance. For Simpana 9 maintenance, add
21% to net license price.) Be aware that the “a la carte” Simpana pricing can save you
money, but you must know exactly which modules and components you need – a
daunting challenge.

Testbed and Methodology
Virtually all our testing took place across 512 kb/s frame relay, T1 and T3 WAN links.
The testbed network consisted of six Fast Ethernet subnet domains routed by Cisco
routers. Our lab's 150 clients consisted of computing platforms that included Windows
2000/2003/XP/Vista/Win7, Macintosh 10.x and Red Hat Linux (both server and
workstation editions).
The relational databases on the network were Oracle, IBM DB2 Universal Database,
Sybase Adaptive Server 12.5 and both Microsoft SQL Server 2008 and 2012. The
network also contained two Web servers (Microsoft IIS and Apache), three e-mail
servers (Exchange, Notes and Sendmail) and several file servers (Windows 2003 and
Windows 2008 servers).
Our virtual computing environments consisted of VMware, XenServer and Microsoft
Hyper-V.
A group of four Compaq Proliant ML570 computers, running Windows 2003 Server,
Windows 2008 Server and Red Hat Enterprise Linux, was our test platform for all the
products’ server components. A second group of four computers simulated our backup
site for disaster recovery.
