Most organisations should have an Intranet. I say most because a two person business running out of homes probably doesnt ‘need’ one but if you are employing people, especially in different locations, an Intranet can (and should) become an integral part of your internal business communications.
What is an Intranet? Think of it simply as a private website for your staff. You can have one just for you if you are just starting out, it can be a central repository of what defines your business and can grow with you. A Wiki is an excellent place to start as it is simple and quick to learn and use. Once the limitations of the Wiki are reached, the Wiki can still have a place in your business process documentation while the Intranet itself can be moved to a Web Content Management System
WordPress or Joomla make great platforms to build your Intranet (see the link above), they are free and very flexible and there are many free add-on/plugins for them to add functionality with no need to know any coding. Joomla has a steeper learning curve but ultimately is more powerful. If you have Windows servers, you could build your Intranet on Windows Sharepoint Services but the initial setup will be the hardest and the learning curve the steepest but the end result may be far more powerful. If you want the full Microsoft Office Sharepoint Server (MOSS), expect to pay for it, it is not at all cheap to buy, customise or maintain.
What can your Intranet do? An Intranet can do anything you want it to do. If you treat it like a consistent homepage only, then that is what it will become. If you limit yourself to not spending any money on it, you will reach a different level of usage, if you see it as the basis for all your company’s internal operations, then that is also what it will become. It is only limted by your imagination. Anything that can be done online can be done in an Intranet, often more as you have a more defined/controlled environment to work with. The Internet’s communications systems are very well designed to be efficient and therefore any remote users or remote offices will often benefit from improved performance with an Intranet based system as opposed to a traditional application. You can use your intranet for company news, internal blogs, documentation, centralised forms and documents, events calendars, discussion forums, training, managing projects, sharing internet links, Client Relationship Management (CRM), process automation (eg Leave applications), testing future web sites etc. (and more).
Your Intranet can be as flashy or as understated as you like but it should reflect your businesses culture and values honestly. Often an Intranet is modelled on the company web site but this is not always a good thing, your staff (internal customers) have very different needs than your external clients. Your staff should be able to contribute easily, either directly or through a few known content Editors. If you make it an integral part your busines, something that has to be used by everyone everyday, it will then be able to become even more. There is nothing more demoralising for staff than a static intranet that is not useful or used for anything that is forced on staff as their browser homepage that has not been updated since it was created, often many years ago where a fresh, relevant and changing Intranet gives a feeling that things are happening in the business.

Regular backups are very important for anyone, especially businesses. While a home user may lose some music or photos if their backups are not up to date, a business may lose invoices, orders, emails etc which cannot be replaced and may have a long term effect on the business.
You really cannot go too far with backups, depending on your risk profile and budget, your backups may be a simple file copy once per day or real time backups pushed to multiple locations. Obviously the more you do the more it will cost but the lower the risk of data loss if something happens.
Before I go into the options, don’t think that it wont happen. It will. Hardware fails, computers die, laptops get dropped or stolen, power spikes occur etc. If you go into this expecting the worst, you are usually in better shape when it happens than those who are not ready for it. Once you have had a significant failure and your backups are not good enough, you tend to take it more seriously in the future.
* Hard Drive Backups
As a bare minimum, and I mean bare minimum, a portable hard drive is a cheap and convenient option to back up your data from one or more locations. It can be a bit manual and does require some discipline but is much easier than burning to CD/DVD. Many come with backup tools but having seen some of them in action, I recommend using a simple backup script to maintain full control over the backup process. Windows (from Vista onwards) ships with a utility called Robocopy which, while small, is one of the best free applications ever to come out of Microsoft. Older versions of Windows can also use it but it needs to be downloaded as part of the Windows 2000 or Windows XP “Resource Kit”. To use it, simply create a folder (call it “scripts”) and create a blank text file, call it “backup.bat”. If you have Windows XP or earlier, you need to put the robocopy.exe file into the same folder. You need to edit backup.bat (right click and edit or it will try to run it). The way you use it is to call robocopy, give it a source location and a destination location and tell it what you want it to do, one command per line. eg robocopy “c:\email” “f:\email” /MIR will use robocopy to “MIRror” the c:\email folder to f:\email assuming that your portable hard drive is allocated drive F:. The /MIR or “mirror” option will delete target files if they no longer exist in the source. This is useful to ensure your backup drive doesnt grow bigger than your data drive but you run the risk of data being lost if the source file get accidently deleted then a backup is run. A better option for a portable hard drive is to have two backups pushed to it, one with the /MIR switch to mirror it and one without which will copy changed files and new files but will not delete anything.
Other Robocopy options can make your backups work better or be a bit more flexible. eg
- robocopy “source folder” “destination folder” /MIR /w:2 /r:2 will wait for two seconds (/w:2) and retry twice (/r:1) if a file is in use and cannot be copied. The defaults are wait 30 seconds and retry 1,000,000 times which will not always be useful.
- robocopy “source folder” “destination folder” /S /log:logfile.txt will copy from the source to the destination including subdirectories (/S) (but not empty subdirectories use “/E” if you want empty subdirectories as well) and will log everything it does to logfile.txt
- robocopy “source folder” “destination folder” /S /XF *.txt *.tmp will copy but will exclude files (/XF) that end with “txt” or “tmp”
Other useful switches are /XD (eXclude Directory), /MOVE (MOVE files and folders, ie delete from source after copying) and /PURGE (delete destination files that no longer exist in the source – used with /E has same effect as /MIR)
A full list of Robocopy options can be found by opening a command prompt and typing “robocopy /?”
The next step up from a USB/eSATA hard drive for disk based backups is a NAS (Network Attached Storage) device. This can be a single drive like the USB connected on or can be a RAID array connecting via NAS, FTP, iSCSI etc depending on your needs and budget. Openfiler can convert pretty much any hardware to a NAS device that Robocopy or another backup system can access for backup storage.
* CD/DVD backups
If you need or want archives of your data for long term storage, DVD backups are cheap and relatively reliable (CD’s as well but since DVD burners and blank DVD’s are so cheap, there is little point persevering with CD’s). A standard blank DVD holds 4.3GB of data which should cover most of your important stuff (documents and emails) for some time. They take up very little space and are readily readable. They do, however, require more work to create, the process cannot be as automated. DVD burning software like Infrarecorder is required (most DVD burners and PC’s will come with some form of burning software which will usually suffice). You will need to know where your data is stored and how much space it takes up.
* Tape Backups
If you have a lot of data and need archiving, the most cost effective solution is a tape backup unit. They are relatively expensive to buy but in Dollars per Megabyte, they are very cheap. The tapes are also very portable which makes it easy for you to transport your data if required (having the most recent tape in your bag each night is better than leaving your tapes onsite if there is a fire!). Tape drives run from a few hundred dollars for slow DAT format tape drives which will do 20GB or so, up to a few thousand for a high speed LTO 4 format tape drive that can hold over 1000GB of data on a single tape (the tapes are more expensive too). They also go much, much higher than this if you decide to opt for a tape library where the backups can span multiple tapes and tape changes are done automatically but I am not going to go into Enterprise class tape libraries here. My rule of thumb is to calculate the storage space you need now, at least triple it and buy a tape system accordingly. While it is possible, I strongly recommend ensuring that your backups dont run longer than a single tape over the lifespan of the tape unit and tapes (you should be able to assume that a DAT drive will last at least 3 years and LTO 4-5 years, the tapes will last longer than this).
* Offsite Backups
There are a number of backup services which, for a fee, provide a quantity of space on the internet where you can upload your files to keep a copy offiste where you can access them as you need them. While they are generally considered reasonably secure, if you are uploading sensitive information, your data should be secured before uploading. Zip archives can be secured with powerful encryption, 7Zip has this functionality built in, simply select the encryption option and put in a secure password and the file will be both compressed (for easier upload) and securely password protected.

A Wiki is something no business should be without.
Wikis (best known in reference to Wikipedia.org) are a simple and fast solution for storing knowledge. The idea is that anyone can edit the information using a set of simple commands to mark up the content rather than needing to know HTML. Mediawiki is the engine behind Wikipedia and is a free and open source web content management system. The code is PHP with a MySQL database so can be set up on any platform (I have set up wiki’s on Windows and Linux without any issues).
A Wiki makes a very good Intranet platform but is better suited to documentation (or a documentation component to enhance an existing intranet) as its layout options are limited (to pretty much one option). Version control is easy (any changes can be rolled back) and users are tracked. A Wiki makes is so easy to quickly add notes, edit, update and create pages that it is no longer an inconvenience (as many people are probably aware, the first thing to fall behind when things get busy is documentation) to keep important documentation current.
To get a feel for how easy it is to “mark up” content for a Wiki, the MediaWiki help:formatiing page is a good place to start.
A Wiki is a centralised repository and can be easily backed up using the built in options in MySQL ensuring that you can keep it safe. By having it in one place that is well known and is also searchable (by its nature), new documentation is less likely to be put somewhere else (which makes it less useful). If this sounds like a strange thing to say, you have obviously not worked in SME IT where the documentation (that I have experienced personally) could be as little as 1 piece of A4 paper printed on both sides, may not have been updated on over 3 years, or may be in 5-6 different locations (electronic and physical or a combination) as each new IT manager moves in and decides to do it their own way.
