In this month's Ask The Expert, I will be explaining to you how to spot the fake security messages on your computer. Just because you get a virus alert message on your computer does not always mean that it is from your computer. Knowing how to read the fake messages could help you tell the difference between a redirect message and a message from a rogue application.

The economy's growing again, though, and IT budgets at big companies are growing - at least according to most analyst reports.

Big vendor companies are going after small user companies not as a way to boost a stubbornly short list of sales prospects; they're doing it because small- and mid-sized companies are - unusually - buying sophisticated IT systems at almost the same rate as big companies.

Well, not buying, really. Renting.

Forty-four percent of small- and mid-sized companies already use at least one SAAS or cloud-based system and 70 percent plan to add more during 2011, according to a survey of 1,000 SMBs carried out in December by market researchers MarketBridge. Marketing and sales-related apps are the leading business apps; security is tops among cloud services.

• Siloed networks that duplicate functions and infrastructure at the access layer.
• Fragmented service at the edge of the network where applications meet users and devices.
• Multiple bolt-on technologies that fail to address the unique needs of user mobility.

As long as enterprises remain entangled in this legacy access infrastructure, IT will be forced to respond to users by saying no - to mobility, to mobile devices, and to accessing business-critical applications.

Aruba MOVE™ unifies disparate wired, wireless, and remote access methods into one cohesive access solution - for traveling business professionals, remote office workers, corporate headquarters employees, and guests. Access privileges are context aware, i.e. based on user, device, application, and location, and this dictates the type of network resources each person is entitled to.

Unitrends supports byte-level deduplication on its backup appliances with its current release 6.  Since there's some confusion concerning byte-level versus block-level deduplication, I thought I'd take the opportunity to explain the differences between file-level deduplication (what Unitrends supported prior to release 6), block-level deduplication, and byte-level deduplication.

File-level deduplication operates by eliminating redundant files.  Despite what many pundits state, file deduplication is very efficient (and note that I'm stating this even though Unitrends employs byte-level deduplication with release 6.)  The reason is two-fold: the concept of temporal data access locality and the concept of data getting "colder."  The bottom line to both of these concepts is that statistically data that has been recently used is more likely to be re-used again while data that hasn't been recently used is less likely to be re-used.  Another consequence of this behavior is the reason that master/differential backup policies have held up so well over time - data usage temporarily tends to be "clumped" together.
