**Responsible computer use (for example, regular back-ups, virus checking, security, storage, housekeeping)** Backups. They are almost required in this day and age if you have important, irreplaceable data or even just your normal, everyday data. Take this hypothetical scenario if, say, your data was on sheets of paper in real life; if the safe in the back room of your house is where you want your data to be, then most of your data is on the front porch, or, if you have a decent firewall (Windows Firewall does not count as decent), it might be on the floor in your entryway. Maybe, if you encrypt it, it will be on the desk in your room or under your pillow, but nothing will be in that safe. If your house gets robbed, if your house burns down, if your house gets toppled like a one-pole tent in an earthquake, or even if your house gets bombed by the Chinese, chances are you've lost that paper.

And how do you get stuff into that safe? Backups. Everything can fail these days. Your hard drive is the most likely, but your whole computer could fail, and if you're running a company with servers, your main server could fail. Say your college thesis was three words from being finished, and your hard drive fails. If you did not have a backup, then you might as well have handwritten the whole thesis and then tossed it in a campfire before handing it in.

We often do not make backups – it takes time, its a boring, repetitive task, and it feels like meteor strike insurance – never needed and totally useless. In fact, however, it's more like health insurance. It doesn't seem needed, but there comes a day when you're quite glad you got it. However, backups are still time-consuming. There are automatic backup systems available, but they cost an arm and a leg and them some. However, excellent and fairly wallet-friendly backup methods do exist.

Most likely the easiest way to do an automatic backup is to create a RAID1 or RAID0+1 hard drive array. RAID0 is data striping across two hard drives, which means blocks are placed on alternating hard drives, thus combining two hard drives into one big one with essentially double the speed. The problem with this is that if one hard drive fails, both fail. All is lost. RAID1, on the other hand, is data mirroring. This means that when ANYTHING is written to the master disk, the second disk writes the exact same thing. Thus, if one hard drive fails, you can pop the other one into the slot and you're home dry. However, is a virus comes and rips up the one hard drive and corrupts all your data, the second one will happily copy all that over and your backup is lost. Finally, RAID0+1, as the name suggests, is a combination of RAID0 and 1. You have four drives, two each striped and one set mirroring the other. This combines the wonderful speed and space of RAID0 with the safety of RAID1, but it fills up all your hard drive slots and viruses will mangle four drives worth of data.

If you are part of a large corporation, then you are better off with expensive backup software. This way, the copying of viruses can be avoided and backups are still non labor-intensive. However, the backups only stay current as long as you keep updating them; if you only perform a backup once a week on Friday and a hard drive fails on Friday morning, then you are set a week behind. The process of backing up large quantities of data is hard-drive usage intensive, so if you perform backups too often you will be in the middle of something and then your computer will slow down to a crawl. If your corporation uses servers or the like, you probably want to backup not just the data, but the entire server, so that when the server goes down another will fill its place while it's getting fixed. This is called redundancy – the replacement doesn't even have to be as powerful as the main server; it just has to keep things from grinding to a halt. Google never goes down because they probably have an insane amount of server redundancy spread out all over the world so they stay online even if a cataclysmic disaster wipes every datacenter west of Chicago off the map.

Finally, you instead of buying a safe, you could buy alarms, cameras, tripwires and maybe even motion detectors and laser tripwires to catch any robbers stupid and unlucky enough to choose your house as his (or her) next target. Just like this, you could install security systems on your computers and servers. In this way, you can protect yourself against any malware; viruses, trojan horses, spyware and keyloggers will not be a threat to the wellbeing of your data. Then again, there have been many cases of these things getting past security, so this method is not perfect. That's not all – just like how you have to step over or deactivate your tripwires when you want to go somewhere, security systems in your computer can be an inconvenience. Norton Antivirus™, for instance, is infamous for slowing down your computer, and other programs block things that you don't want blocked. And on top of all these problems, security won't protect you against a hard drive failure.

It's better to shell out $3,000 for a good, fireproof safe than losing 50 grand worth of money and important documents in a fire or a thief. In the same way, all these problems and expenses with backups are still better than losing all your data and getting fired if that data was your employer's. A wise man once said, “You can fix the idiot in the computer, but you can't fix the idiot at the computer.” You can keep the computer from crashing and screwing up, but you can't keep the user from screwing up and that includes the user not backing up things that are important. I admit that even I do not perform regular backups; in fact, if my computer exploded right at this very instant, I think I would lose half of all the torrents I've downloaded and most of the recent additions to my website.

 **Basics**  Many people own their own computer, whether a desktop or laptop, and their number is increasing daily. Along with owning your own computer comes a responsibility. You should take care of the computer and make sure that the computer and your data stay in good condition. This can refer to [|back-ups], [|virus] checking, [|security] ,[|storage] , housekeeping, and more. **Backing Up Data** Firstly, when dealing with your data, you have to acknowledge the fact that it can be lost, damaged, or deleted. Because of this, computer owners must make back-ups of their data. Back-ups on a remote server, external hard-drive, or in various other locations can prove very helpful in the case of irretrievable data. Detailed information about back-ups, and how to make them is found in the link at the top of the page.  **Security and Viruses** Next, security is a large aspect of responsible computer use. You should always keep yourself and your data protected. Whether this protection is from hackers, viruses, worms, spyware, or so on, you should always keep these things in mind. Viruses can not only damage your computer, but can damage other computers in which yours is connected to. That is why it is important to routinely check for viruses using programs such as Norton AntiVirus, which contains a scan as a utility. There are many methods to increase your security and virus protection, and more information via the links above. **Storage** Responsible storage methods are important for a computer just as back-ups are. Firstly, it is important to have sufficient storage capacity for your files and data. This can be in the form of a hard-drive, flash-drive, external hard-drive, or storage server. Similarly, it is vital to not use up all the storage capacity you have on your computer's internal storage devices. This will slow down the computer and render it more succeptible to problems such as computer crashes and data corruption. For more information on storage check out the link at the top of the page. **Housekeeping** <span style="background-color: transparent; border-bottom-color: #aa0000; border-bottom-style: solid; border-bottom-width: 1px; color: #000000; text-decoration: none;"> //"When referring to computers, housekeeping is a term used to describe the optimization of a hard disk drive. Housekeeping commonly involves removing old or unused files, removing programs no longer being used, backing up data, and/or running disk utilities such as a scandisk, defrag, or a virus scan. Housekeeping is meant as a way to help keep the computer organized and running properly and should be performed at least once a year."// -<span style="background-color: transparent; border-bottom-color: #aa0000; border-bottom-style: solid; border-bottom-width: 1px; color: #000000; text-decoration: none;">Computer Hope.com Accessed March 2007 This includes the cleanliness of the computer on the inside and out, the protection from power surges, battery replacements, disk defragmentation, and much more.
