CA ARCserve r16.5 vs.

Transcription

1 Our quest to find the best backup/restore, disaster recovery, replication and business continuity product looks at the latest versions of CA ARCserve (r16.5) and StorageCraft ShadowProtect (V5). Executive Summary CA ARCserve r16.5 s features, usability and performance far outstrip those of StorageCraft ShadowProtect V5. Simplistic and unsophisticated, ShadowProtect is only minimally useful. We found ShadowProtect to be merely a pale and slow shadow when compared to CA ARCserve. CA ARCserve has many features and functions that StorageCraft ShadowProtect completely lacks. These include file-based backup, comprehensive replication and automated high availability for the Windows, Linux and UNIX environments. StorageCraft ShadowProtect can only do image-based backup of Windows machines. In testing, CA ARCserve r16.5 s image-based backup component was faster than StorageCraft ShadowProtect V5, it used superior technologies (such as Infinite Incrementals), it worked with more cloud vendors, it supported Linux, it offered Virtual Standby for automated cold failover and CA ARCserve s reports were far more useful and informative. Moreover, CA ARCserve r16.5 was priced lower than StorageCraft ShadowProtect V5. CA ARCserve r16.5 is the clear choice for those organizations needing quality, high performance backup/restore as well as maximum high availability and replication. CA ARCserve r16.5 yet again earns the World Class Award for best data protection and business continuity. CA ARCserve r16.5 and StorageCraft ShadowProtect V5 both offer to protect and preserve your data using a variety of backup/restore approaches. Both have many features to tempt organizations needing to protect critical data from failures, disasters and human mistakes. Both provide image-based backups for Windows environments. How do CA ARCserve r16.5 and StorageCraft ShadowProtect V5 measure up? Which is best suited to your particular computing environment? Disclosure: ion of this report funded by CA, Inc.

2 We decided to look closely and in detail at the abilities and shortcomings of both CA ARCserve r16.5 and StorageCraft ShadowProtect V5. In this report, we compare and contrast the two products, feature by feature. Unlike the more feature-complete CA ARCserve, StorageCraft ShadowProtect can produce only image-based backups. StorageCraft ShadowProtect does not do filebased backup and recovery, has no replication capability and does not offer high availability. Accordingly, we ve had to assign StorageCraft ShadowProtect zero scores in the file-based, replication and high availability-based sections of this report. CA ARCserve s components are CA ARCserve Backup (file-based), CA ARCserve D2D (image-based), CA ARCserve Replication (for disaster recovery) and CA ARCserve High Availability (for rapid system failover and business continuity). StorageCraft ShadowProtect s components consist of ShadowProtect Console, ShadowProtect Backup Agent, ShadowProtect VirtualBoot, ShadowProtect ImageReady, StorageCraft Recovery Environment and StorageCraft ImageManager. CA ARCserve r16.5 s improvements include: Windows Server 2012 Support, All Areas NTFS deduplication support Resilient File System (ReFS) support Hyper-V 3.0 support Distributed VSS support Storage Spaces support CA ARCserve s image- and file-based backup also support Windows 8.

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 StorageCraft ShadowProtect fare in producing and recovering image-based backups. Image-based Backup An image-based full system backup contains everything about a computer system 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. Copyright All rights reserved

6 Image-based Backup Notes CA ARCserve outshines ShadowProtect in several ways with respect to image-based data protection. CA ARCserve implements a superior synthetic backup technology (termed Infinite Incremental), it works with several vendors clouds, it supports Linux, it is far faster, it offers virtual standby for quick, cold-failover and CA ARCserve integrates with more MSPs. CA ARCserve s reports are easier to use and understand. And CA ARCserve s image-based component integrates closely with CA ARCserve s file-based backup, replication and high availability components. ShadowProtect has only a couple of minor advantages it supports Oracle VirtualBox and can create ISO-based removable disks. Snapshot Technology CA ARCserve and ShadowProtect create backup images of physical and virtual environments, and both back up and recover clients as well as servers. Furthermore, both CA ARCserve and ShadowProtect offer synthetic backups, in which a full backup is assembled, or synthesized, from a baseline full backup and subsequent incremental backups. Significantly, CA ARCserve offers true infinite incremental snapshot/image-based backups. Unfortunately, StorageCraft ShadowProtect can t create incremental backups in the presence of Microsoft VolSnap plus Microsoft VSS. ShadowProtect needs to use StorageCraft s own Volume Storage Manager (VSM) in place of VolSnap in order to produce incrementals. In sharp contrast, CA ARCserve does use Microsoft VSS to create its Infinite Incremental snapshots. CA ARCserve s image-based backup is built on its patent-pending Infinite Incremental (I 2 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. Neither CA ARCserve s image-based component nor ShadowProtect offer data deduplication. Both CA ARCserve and ShadowProtect can create snapshots as often as every 15 minutes Operating Systems, BMR StorageCraft ShadowProtect supports only Windows, while CA ARCserve protects both Windows and Linux computer systems. Via Bare Metal Recovery (BMR), CA ARCserve can restore Windows images and Linux images onto similar or dissimilar hardware. StorageCraft terms its Bare Metal Recovery process, which supports only Windows, Hardware Independent Restore (HIR). Copyright All rights reserved

7 Cloud Support CA ARCserve s image-based component works with Amazon Web Services (AWS), Fujitsu Cloud and Microsoft Azure public clouds to store critical information offsite for disaster recovery. CA ARCserve also supports Eucalyptus 3.x (an open source, AWS-compatible private cloud). CA ARCserve writes initial snapshot (backup) to disk. A subsequent step copies the file/folder data to a cloud. Once the first image copy is stored in the cloud, CA ARCserve transmits only incremental changes (via I 2 ) from that point forward. This makes the best use of either low-speed cloud connections or expensive high-speed cloud connections. StorageCraft ShadowProtect can store images only in StorageCraft s own proprietary, extra-cost cloud product, called StorageCraft Cloud Services, which consists of a West coast and an East coast StorageCraft data center. Remote Management via Managed Service Providers (MSPs) Two MSPs, Kaseya and Labtech Software, have embraced both CA ARCserve and StorageCraft ShadowProtect. A variety of additional MSPs (such as n-able) additionally support CA ARCserve. Performance and Media Usage CA ARCserve s I 2 is faster than ShadowProtect s synthetic full backup process. For a complete system comprising 300 GB, Figure 1 shows the relative backup and restore performance of the two products. ShadowProtect was, on average, 20% slower than CA ARCserve. CA ARCserve StorageCraft ShadowProtect 40.0 Figure CA ARCserve I 2 vs. StorageCraft ShadowProtect image-based backup/restore performance Total System Copy Time (Minutes) Total System Restore Time (Minutes) Copyright All rights reserved

8 Moreover, we noted that CA ARCserve needed less storage space (166 GB) than ShadowProtect (180 GB) for its image-based backups. Both products use compression to reduce storage requirements. We concluded that CA ARCserve used less space because its compression technology is more advanced. In this test, we created and retained daily, weekly and monthly backups over a three-month time span, and our data contained few duplicates. Figure 2 depicts the resulting disk usage Disk Space Used (GB) Figure 2. CA ARCserve I 2 vs. StorageCraft ShadowProtect imagebased disk storage utilization 155 CA ARCserve StorageCraft ShadowProtect Virtualization Support -- CA ARCserve and StorageCraft ShadowProtect both support VMware ESX and vsphere, Microsoft Hyper-V, Red Hat and Citrix XenServer. ShadowProtect additionally works with Oracle s VM, VirtualBox. CA ARCserve s unique host-based backup for VMware (D2D Central Host-based VM Backup) protects all VMs on an ESX server without having to install CA ARCserve in each VM. Impressively, CA ARCserve restored data to a virtual machine in our tests more quickly than did StorageCraft ShadowProtect. Figure 3 graphically illustrates this difference. CA ARCserve finished the restore operation in only 14.4 minutes, while ShadowProtect Copyright All rights reserved

9 took 18.6 minutes to restore the same data. This test used 980 GB of diverse information stored in a repository of a full backup plus 8,640 incrementals Average VM Restore Time (minutes) Figure 3. CA ARCserve I 2 vs. StorageCraft ShadowProtect VM restoration time 0.0 CA ARCserve StorageCraft ShadowProtect 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. Of StorageCraft Cloud Services three increasingly expensive tiers of support (Cloud Basic, Cloud+ and Cloud Premium), the highest (costliest) tier, Cloud Premium, offers the translation of cloud-stored image files into virtualized images. However, this premium translation service falls far short of CA ARCserve s Virtual Standby feature. RTO/RPO Performance Testing To measure CA ARCserve s and StorageCraft ShadowProtect 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. Both CA ARCserve and StorageCraft ShadowProtect created snapshots every thirty minutes and transferred the backup material to a remote location. Four computers at the Copyright All rights reserved

10 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 StorageCraft ShadowProtect 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 (available to users). The CA ARCserve administrator needed just 49 minutes to restore data to the servers and resume the OLTP application. The StorageCraft ShadowProtect administrator needed significantly more time (57 minutes nearly an hour) to accomplish the same thing. Central Management Working with disk images is easy and painless with CA ARCserve's Web 2.0-based management console, and we could access its Rich Internet Application (RIA) Web browser interface from any client computer. StorageCraft s central monitoring and reporting console for ShadowProtect is ShadowControl CMD. The CMD product consists of two main components, the CMD Appliance (a Linux-based server running on dedicated hardware) and CMD Agent (a thick Windows computer program installed on each client/workstation computer). Central Reporting CA ARCserve s Central Reporting component produced useful and informative reports regarding backup and recovery operations and schedules. The reports CA includes with CA ARCserve are: Alerts Application Data Trends Backup Size Trends Volume Trends CPU Utilization Memory Utilization Network Utilization Node Archive Status Node Backup Status Virtualization Protection Status Data Distribution on Media StorageCraft ShadowProtect produces only a single summary report containing four sections on backup and restore operations. (ShadowProtect also regularly produces a license usage report, but it isn t useful in tracking backup and restore operations.) ShadowProtect can send the single summary report daily (covering the last 24 hours), weekly (covering the last seven days) or monthly (covering the last 30 days). Copyright All rights reserved

11 The four sections of a ShadowProtect report are Summary, Endpoint Backup, Endpoint Status and Storage Summary. o Summary Section: Displays a chart of the number of Endpoints that are Critical, Warning, Good or Offline, a chart of the backup success rate for the report's time period, and a list of ShadowProtect installations and platforms. o Endpoint Backup Section: Displays a list of the Endpoints by organization, their backup success rate for the report's time period, and when their last backup occurred. o Endpoint Status Section: Displays a list of the Endpoints by organization with the percent of time ShadowProtect detected the EndPoint, the average number of times per day the Endpoint is offline, the Endpoint's current status (Critical, Warning, Offline, Good) and Operating System version details. o Storage Summary Section: Displays a set of daily averages for the amount of disk space used by backup image files. ShadowProtect uses this data to create a chart of projected storage space requirements for the next 3, 6, and 12 months. Accessing CA ARCserve s many reports through its dashboard interface is easy, quick and intuitive. The ShadowProtect report facility interface consists essentially of just a scheduling option (daily, weekly, monthly or none). In the next chart, we take a detailed look at CA ARCserve r16.5 and StorageCraft ShadowProtect V5 file-based backup and restore capabilities. Note: StorageCraft ShadowProtect does not offer any file-based backup to disk or tape and therefore scored zero for all features in this category. By using CA ARCserve s file backup tape capabilities along with its image backup, you can quickly and easily copy backups to tape for archiving purposes. CA ARCserve s image and file backup technologies are well-integrated for ease of use. 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 Copyright All rights reserved

12 has an operating system installed on it. However, most file-based backup products also offer some type of bare metal restore (BMR) for system recovery.

It is purely imagebased. Copyright All rights reserved

13 CA ARCserve r16 has a wealth of file-based backup features. Moreover, it s fast, reliable and frugal in its use of storage space. CA ARCserve supports myriads of operating systems, applications and backup devices. CA ARCserve has superior reporting, its infrastructure visualization and its central management console is responsive and intuitive. 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. 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. In the last features table, let s examine the differences between CA ARCserve and StorageCraft ShadowProtect 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. Note: StorageCraft ShadowProtect does not offer any replication or high availability features and therefore scored zero for all features in this category. Copyright All rights reserved

14 Replication and High Availability Features Comparison Table (Scoring from 0 to 5, with 5 the highest) Feature StorageCraft ShadowProtect V5 CA ARCserve r16.5 Replication True high availability (hot failover) Physical and virtual server support Operating System and application support RTO/RPO (for disaster recovery) Cloud Integration Continuous Data Protection (CDP) Offline synchronization Replication and HA recovery testing Network optimization Replication and backup integration Assessment mode utility Application aware replication Replication and high availability features aggregate ranking Replication and High Availability Notes CA ARCserve s replication component may be used in a scheduled fashion to migrate and manage offsite backups. In a real-time, continuous manner, CA ARCserve provides true Continuous Data Protection (CDP). CA ARCserve s replication target can be (and often is) an offsite set of servers or a cloud. Copyright All rights reserved

15 CA ARCserve s replication component performs asynchronous replication and supports Windows, Linux and UNIX environments. They may be deployed onsite, offsite and/or linked to a cloud. Basically, CA ARCserve s replication feature clones each I/O operation and sends the cloned copy to a secondary destination of your choice. CA ARCserve can replicate between physical and virtual servers (P2P, P2V and V2P) and between virtual server platforms (V2V). By using both CA ARCserve s replication and file-based components, we easily made archive copies of replication backups. For companies needing maximum system uptime and availability, CA ARCserve has a High Availability (HA) component. 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. StorageCraft ShadowProtect has no high availability capabilities. It completely lacks CA ARCserve s feature-rich, mature ability to replicate, monitor and automatically fail over critical servers. CA ARCserve s HA component 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. 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. CA ARCserve comes with many pre-built replication and high availability scenarios. Furthermore, it provides application-aware replication and failover for Exchange, SQL Copyright All rights reserved

16 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. CA ARCserve s high availability support for Windows server clusters can replicate and automatically failover Windows clusters as well as replicate to Windows clusters. CA ARCserve s Replication and High Availability components include an easy-to-use 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 and end user access or impacting the continuous data protection and monitoring. 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. StorageCraft ShadowProtect, which has no high availability feature, required the same 57 minutes as in the previous test to recover from the simulated disaster. Ease of Use and Pricing CA ARCserve s well-formatted and configurable dashboard reveals, at a glance, the current status of your backups. ShadowProtect s interface displays just three menu options (labeled Navigation, Main and Session). The Navigation Panel, located at the left side of the console, simply provides options for tasks and configuration settings. The Main Panel, located at the center of the console, displays lists of computers participating in backup operations (StorageCraft calls them Endpoints). The Session Panel, located at the top right of the console, displays the current username and appliance ID, along with a few backup session options. If you have multiple site backups, both CA ARCserve and ShadowProtect consolidate and centralize backup status information from all sites. Data visibility is crucial to data backup reliability. CA ARCserve needs only a single click to display a clear and highly descriptive graphical view of backup sets and backed up data. ShadowProtect requires considerable administrator manual input in order to show backup and restore status information. CA ARCserve s image-based backup component has a Web 2.0 interface that uses browser windows to provide real-time access to the latest documentation updates, Copyright All rights reserved

17 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. ShadowProtect s appliance-based software is not as informative, as responsive or as intuitive to use as CA ARCserve s. 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. StorageCraft ShadowProtect s pricing is generally higher than that of CA ARCserve, as shown in the following tables. Note that CA ARCserve pricing includes maintenance. StorageCraft ShadowProtect pricing does not.
