Using an Off Line UPS Battery Backup and APC UPS Backup Battery Tester to Protect Data

By Elliott Turner

Any business or any home office needs to have a UPS battery backup system running from day one in order to protect the business's data and make sure that service isn't interrupted.  For businesses that deal in telecommunications or other industries where continual service is the core of what the business offers to customers having a high quality UPS battery backup is essential. Besides the backup system itself, every business should have at least one ups battery tester that can make sure that the system is running on full power and is ready to go at anytime you may need it.  Businesses can choose from one of three different kinds of backup supplies.  It doesn't matter what type of system a business chooses as long as it fits the application they need it for.  

The ups battery tester should always be used regularly to make sure that the UPS system is functioning and is ready to go when needed.  An offline UPS battery backup system stays dormant until the power goes out and then it instantly turns on and redirects its own battery power to the original source to protect data and keep your critical systems online.  Businesses can save money by using an offline system since it doesn't do anything until the power actually goes off.  However, since the unit will probably just sit until there is a power shortage, it is even more important to use an offline battery tester to actually test the batteries inside the UPS system itself.  After all the batteries are the most important part of your system.   Sitting around for a long time means that if something is wrong with the unit or if the battery is not holding a charge then no one will know that until the critical moment when the power is needed and by then it will be too late.

Using an offline UPS battery backup can be a more economical option for businesses than using an online or line-interactive UPS battery backup through their entire location, so it makes sense that most small businesses or start up businesses go for an offline UPS battery backup system at first.  Remember it is very important to have your battery backup system tested regularly and this is something you can do in house or sub out to a testing company.  Regular testing of the system should be done according to a schedule.  A smart and simple way to keep track is to write on a calendar each date that the backup system should be tested and then when the battery tester has finished the testing process that person can make a big red "X" through the date so it's clear when the test was done.

The HTiB Options of the Modern Home Theatre Market

In the movie "The Wedding Singer," Drew Barrymore's fiance comes home with his latest purchase, a CD player. He's very happy with his accomplishment because, being the materialistic kind of guy that he is, he's proud of thee fact that it cost about $700. Of course, the joke is on him and the entire audience knows it, because the average price of a CD player today is only a couple of hundred dollars. Still, in 1985, the year in which this movie is set, I'm sure that $700 for a CD player was a good deal.

All electronics, from computers to alarm clocks, are prohibitively expensive when the first come on the market, but they become more affordable as time goes on. Home theatre audio systems have been no different. What was once a luxury item that only people like Donald Trump could afford is now something that tens of thousands of Americans have in their homes. The market has been, and continues to be, flooded with new and cheaper audio systems, especially those of the HTiB, or Home Theatre in a Box, variety. But again, as with all electronics, you get what you pay for, and not all of these systems are created equal. When selecting a home theatre audio system, there are several factors that need to be balanced, including quality, price, and size.

If you're in college, don't have a lot of disposable income, but simply must have a home theatre audio system, chances are you're going to end up with a budget-priced HTiB. These systems, which usually feature small satellite speakers and subwoofers, have an inclination toward spotty sound quality and lack sheer oomph. To quote Napster in The Italian Job, a budget-priced HTiB will never be "loud enough to blow women's clothes off." But while Napster might disapprove, such systems have their upsides. They are, as mentioned, affordable for the average individual, and they also tend to have the advantages of being compact and comparatively easy to assemble.

Or perhaps you own a downtown loft in a high rise somewhere and you want a theatre audio system that coordinates with such an ambiance. Some HTiB manufactures offer systems that feature style and are overtly sleek in appearance. A home theatre audio system that goes this route will often have very petite satellite speakers, or perhaps "tallboys," which are very slender but as much as sixty inches tall. The advantage of a style-centric HTiB, in addition to its elegant appearance, will probably include lots of features and simplicity of set up. The disadvantages? Such a system will probably have limited bass output and limited connectivity options.

Some manufactures are now offering component packages, which are built around separate components. These systems, while forfeiting the traditional HTiB advantage of compactness, usually have the benefits of solid build quality and variety of features. However, as mentioned, such a home theatre audio system will probably be fairly large and clunky, which won't work if you need to fit it into your studio apartment.

Finally, if you want to go cutting-edge, there are wireless HTiB systems that utilize the very latest in audio technology. These are great if you can afford them, since they save space while maintaining high quality. But as mentioned, they can be extremely expensive and in some cases, you're better off buying separate components.

DDoS Attack Prevention - The Best Medicine

Denial of Service (along with their lesser known cousins, Distributed Denial of Service) attacks can be a network administrators worse nightmare. Once they are underway they're extremely difficult to resolve quickly, and could cost a business hours of productivity and frustration as people are unable to access your web services or remote access their work. What is a DDoS attack? And more importantly, what are the best methods to prevent a DDoS attack?

A Distributed Denial of Service attack is when malicious users target corporate servers with false or faulty service requests, flooding the servers with traffic until they shut down, or at the least become so busy sorting bogus internet traffic that actual data traffic is unable to get through. This can cripple or totally shut down web, email, and any other data transport services that your business needs to get its work done, resulting in many lost man hours as the problems are resolved. There are however several ways to prevent attacks, and a quality managed hosting company will use some or all of them on its dedicated servers.

The first and most important line of defense is a traffic analyzer. These software products consists of a suite of computer programs that constantly analyze the source and details of traffic, looking for the most common signs of false traffic requests and other markers that are frequently found as part of DDoS attacks. Once this sort of traffic is found, the best software is capable of filtering it out and preventing it from reaching the server in the first place. Then, in the next line of defense, a dedicated server company will have a firewall that further filters traffic. Firewalls work by preventing access to rarely used server ports and resources according to specified guidelines. By restricting these usually unprotected resources in the server's software, firewalls block and prevent some of the most common access points and weak spots for Denial of Service attacks. And finally, many managed hosting companies will provide a backup cluster with a separate and distinct address and data connection, so that in the event of a DDoS attack, services can be switched over to the backup which remains unaffected.
