Companies of all sizes have to war with two = competing=20 goals when it comes to management of their mission-critical data: 1) = protecting=20 their data in the event of disaster; and 2) maintaining the highest = level of=20 data security. The first requires letting go, while the second demands = holding=20 fast.

Web 2.0 is=20 Here=96 Is Your Web Infrastructure Ready?
Web 2.0 has paved = the way=20 for a new level of interaction between shoppers and retailers. However, = without=20 rapid delivery of your rich Web content, the benefits will go = unrealized.=20 Maximize the value of your interactive Web site. Read White Paper Now. =

For most businesses, data security is a = mission-critical=20 undertaking, and a summer of weather calamities drove home that = point.

"As the recent hurricanes reminded us, off-premise backup solutions = can make=20 the difference between being out of business for good and being on = hiatus for a=20 few months," Rob Enderle, principal analyst with the Enderle Group, told = TechNewsWorld.

A Complicated Question

The question of which Web-hosted storage system is the best choice for any particular business = can be a=20 complicated one.

"A handful of products are agent-based -- meaning that an application = is=20 loaded on a customer's server or workstation with a defined set of files = or=20 folders to back up over the Internet via FTP (file transfer protocol) or = some=20 other transfer medium," Terrance Bush, spokesperson for FastServers.Net, told=20 TechNewsWorld. "Others employ a Web front end, and allow their customers = to=20 select files locally on their computer to upload."

Getting a handle on all the different types of Web-hosted systems is=20 difficult in itself, said Charles King, principal analyst at Pund-IT.

"The sheer variety of options makes this hard to define precisely," = he told=20 TechNewsWorld. "They range from highly specialized solutions and vendors = aimed=20 at specific applications or types of data, to broad offerings from major = vendors=20 like IBM (NYSE: IBM) and HP (NYSE: HPQ) . Suffice it to say that if you look hard enough, you'll = likely=20 find an online storage solution to meet virtually any business = need."

Amazon S3 = is perhaps=20 the best-known of Web-based storage solutions, said Jonah Stein, = president of Itstheroi.com.

"But a variety of alternatives are available that are better suited = to=20 enterprise environments because they offer Service Level Agreements = and=20 direct access to customer support -- two items that are essential for = any=20 business considering moving storage to a service provider," he told=20 TechNewsWorld.

Mozy from EMC (NYSE: EMC) is a good online choice for small to mid-sized = businesses, said=20 Roger Kay, principal analyst with Endpoint Technologies.

Mix and Match

Sometimes, though, it's desirable for a business to take a mixed = approach to=20 data storage, Kay said.

"The cloud model is still immature, but ideally a business could take = advantage of certain online capabilities while keeping the most critical = data=20 in-house," he told TechNewsWorld. "Still, you need to back up -- = preferably=20 off-site -- the data you really don't want to lose. Think of what must = have=20 happened to any unique data stored in Galveston [when Hurricane Ike=20 struck]."

A rising star for businesses is 3tera, Stein suggested.

"They have been leading the technology revolution that is the road = map to=20 real cloud computing since 2006," he said.

"Amazon EC2 and Google Apps are important, but they are not viable = solutions=20 for the enterprise because they force companies to rewrite solutions for = their=20 applications and lack portability," Stein maintained. "3tera supports = cloud=20 computing for applications developed in LAMP, Solaris, Java or Windows .Net without a = significant=20 development effort."

Virtually every storage strategy has its positives and negatives.

The best choice depends on a client's needs, Bush noted.

"Not all of our customers are the same; each has a specific set of=20 requirements needed for their storage needs and business continuity = practices,"=20 he said. "One example would be disk-to-disk backups locally stored and = available=20 within their hosted solution for immediate data recovery. Others support = backups=20 that are stored externally from their hosting solution, but within the = facility=20 for moderate-to-fast recovery."

Still others may have particular compliance or regulatory concerns. = They=20 might need to store data externally or housed at another location = separate from=20 their primary hosted location, Bush added.

Sorting Out Pros and Cons

A mixed approach is typical.

"You have online, near line, and offline storage in a well-managed = shop to=20 address availability, cost of storage, and recovery in case of disaster. = I'm=20 looking at issues like availability, disaster recovery, security and = pricing,"=20 Enderle said.

"The pros and cons generally have to do with price and reliability, = and the=20 two aren't always well connected," he observed. "This is where folks = have to be=20 careful to make sure the provider will be around and has some experience = doing=20 this, as an 'oops' can cost even more than any potential service = savings."

The right storage approach can be cost-effective, requires little = training=20 and is easy to manage and operate, Bush said.

On the other side of the coin are potential drawbacks, including the = risk of=20 "sending traffic over the Internet, especially if unencrypted; data = corruption=20 with transfer; or a provider losing data due to negligence or = exploit."

"FastServers provides dedicated hosting solutions for our clientele," = Bush=20 said. "Most of the storage and backup solutions that we provide to our = customer=20 base are in combination with their hosting needs. We do provide = [disaster=20 recovery] facilities for customers to host a 'warm/hot spare' -- = identical=20 infrastructure of production environment in standby mode -- but we do = not=20 provide open solutions for consumers or home users."

Cost will always factor into any backup solution, Bush noted.

"The amount of storage required, retention and recovery points all = come into=20 play when researching backup options," he said. "The best advice is to = do a=20 serious amount of research, review your infrastructure, and speak with a = provider to see if their product offering meets your needs."

Many businesses take the "appetizer" approach, King noted, testing = one or two=20 services to see how well they work with existing IT strategies.

"It's critically important that organizations make sure certain = online=20 services are up to snuff before they commit critical data to the cloud," = he=20 said.
