Free Cobian Backup for Windows

"Cobian Backup is not a usual backup application: it only copies your files and folders in original or compressed mode to other destination, creating a security copy as a result. So Cobian Backup can be better described as a "Scheduler for security copies"

IP Cameras and Power Over Ethernet

"PoE will save you money. Installation is quicker and easier and there is no disruption while holes are cut into walls. You simply run an Ethernet cable from the camera to the switch or router and connect it to a PoE port, or use a one-port power injector. Either way, no AC contractor is needed, the camera gets all the power it needs and, the worst case scenario in terms of expense is a PoE port that might cost £30."

"

• Power over Ethernet (PoE) deployment is currently difficult for external installations as the anti-condensation heaters in cameras can’t yet be powered via PoE. The IEEE is working on a new, higher wattage PoE standard (802.3at or PoE Plus) however, for possible release by the end of 2008. See http://www.techworld.com/midsizedbusiness /news/index.cfm?newsid=5224
• PoE can’t currently drive Pan Tilt Zoom (PTZ) camera motors either. Consider a camera that doesn’t use moving parts.
• Avoid self-installation unless you’re fully qualified. Work with qualified electricians and cabling contractors for larger cabling jobs.

A useful bandwidth calculator is available from Axis you can also call them on 0870 162 0047 to request a cd containing the tool."

DO

• Consider the importance of cabling – Cat5e is ideal...
• ... as is wireless for campus environments and large external areas like car parks.
• Deliver 1 Gigabit per second (Gbps) to the desktop...100 mbps at least.
• Increase your storage. A 10-camera system could generate 2TeraBytes (TB) of data when storing 28 days of medium compression video, if its cameras are running on motion detection only.
• Use medium compression to avoid image pixilation and blockiness.
• Collect data using MJPEG format if possible. It’s slightly more data hungry, but also more reliable than MPEG-4 with superior image quality.
• Check the light levels you expect cameras to work down to. Spec cameras that operate down to a minimum of two lux or offer day/night infrared-assisted capability once light levels slip to 0.2 lux or below
• Conduct a thorough site review – if cameras must be sited a long way from the areas they’re monitoring, high specification lenses may be required.
• Consider budget. Entry-level static network cameras can be a quarter of the price of PTZs (Pan Tilt Zoom cameras).
• Consider using Uninterruptible Power Supplies (UPSs) to ensure smooth power supply to cameras. Surges can blow power supplies in video recorders and cameras, adding to overheads
• Consider deploying Power over Ethernet (PoE) cameras indoors. Savings on the installation of individual supplies to each camera can be as much as £100 per camera. PoE also enables central power control via a UPS and prevents cameras being disabled by removing the local fuse.
• Mount cameras to avoid casual vandalism. Poles are useful here. Alternatively consider vandal and tamper resistant models. Some now even alarm if obscured for any reason
• Apply username and password authentication for access to video images
• Consider demarcating surveillance data on a separate part of the corporate network – possibly establishing a new virtual Local Area Network (VLAN)."

Moore's Law:
Computing power doubles every 2 years
http://en.wikipedia.org/wiki/Moore's_law

(Jakob) Nielsen's Law:
"stated that network connection speeds for high-end home users would increase 50% per year, or double every 21 months."
This means that by 2033 we will have 200,000 x more bandwidth.

When people talk about Ethernet today, they are typically talking about Fast Ethernet which is a standards-based method of connecting devices together in a network. This could be, for example, a PC connected to an ADSL or broadband router or multiple PCs connected together through a switch. Fast Ethernet is the main Ethernet technology on the market for wired technology and it runs at 100Mbps – that’s megabits per second.

What about Gigabit Ethernet?

Gigabit Ethernet is the next step up from Fast Ethernet. Again, it is standards-based technology and provides a data rate of 1000Mbps or (one gigabit). While it is most often used as the backbone in many large networks, use of gigabit Ethernet is on the rise in smaller businesses. In fact for the majority of SMEs, in 18 months to two years time it will be cheaper to buy a Gigabit Ethernet product than a Fast Ethernet product. As demand for the latter declines, businesses will need to start looking at Gigabit Ethernet in order to future proof their networks.

And where does 10-Gigabit Ethernet fit in?

A10-gigabit Ethernet is another standards-based technology which, as the name suggests, is 10 times faster than Gigabit Ethernet and offers data speeds of up to 10 billion bits per second. It is a new technology which is expected to be used to interconnect local, wide and metropolitan area networks. However, unlike Gigabit Ethernet and Fast Ethernet it uses optical fibre for data transmission. For this reason we won’t see 10-gigabit Ethernet in smaller businesses just yet, because of the costs associated with fibre which requires specialist installation or transceivers.

Can’t I just use Wi-Fi?

Yes and Wi-Fi can provide the flexibility of being able to connect to the network from anywhere in the office, but tends to be slower and less reliable than wired technology such as Ethernet – as the strength of the signal can be affected by wall thickness and the age of the building.

What about PowerLine?

PowerLine is another technology which bypasses the need for a traditional wired IT infrastructure. Unlike Ethernet which requires traditional cabling, businesses using PowerLine can create an office network simply by using the existing electrical mains circuit within the building. This is ideal for a small office but the downside is that although PowerLine runs at up to 200Mbps – twice as fast as fast Ethernet – it is a shared bandwidth technology so the more devices which are plugged in, the lower the bandwidth to each device will become. This makes it a technology suitable only for very small businesses with few network devices, such as home offices.

How should I decide which one is best for my business?

Generally, in smaller businesses where budget is strictly limited or traditional structured cabling is unsuitable and there is not a huge bandwidth requirement, then wireless or PowerLine are probably the best options.

However, for the average SME, Gigabit Ethernet will be your best bet. Although you may be able to use Fast Ethernet to the desktop for years to come, as your business grows the demands on the network will also rise and using Gigabit Ethernet will prevent bottlenecks developing.

Our network is running perfectly well, so do I really need Gigabit Ethernet?

Small businesses really should be buying Gigabit as opposed to Fast Ethernet switches when upgrading or updating their networks. For the majority of SMEs, the adoption of 10-gigabit Ethernet technology won’t be for some time yet. However, it is worth bearing in mind that if your business grows rapidly, if you need to share large files or plan on adding IPTV or Voice over IP to your network then it is highly likely that you’ll need 10-gigabit Ethernet sooner rather than later.

The biggest concern for SMEs, in particular those that don’t have a dedicated IT department, is that more and more applications are being loaded onto the network and employees are more reliant than ever before on using email and the Internet to do their jobs. If the business suddenly couldn’t get to the email server, for example, because there was too much information on the network, it could have a real impact on the business.

Isn't it going to be expensive to move to these technologies?

As a migration path, most businesses that have Fast Ethernet in the business today move these products to areas which require less bandwidth and deploy the newer products in the higher demand areas. In any case, the price point between Gigabit and Fast Ethernet is getting closer. The real question perhaps is what price can be put on the business being capable to handle the next generation of applications and be future proofed?

In addition, manufacturers have worked hard to develop and enhance the web managed range of products which enable the selection of applications by drop down menus in order to make the infrastructure easier and less costly to manage. This is perfect for the smaller business with basic prioritisation requirements. Once the business network reaches a certain size, the need to migrate to a more configurable fully managed solution is advisable.

How long can I expect my gigabit / 10 gigabit network to last?

Currently there are very few applications that require more than Gigabit to the desktop so realistically, until the content and applications increase, we will not see a migration to a faster technology in the short- to mid-term.

How will I know that I'm getting a return on my investment?

This needs to be measured through the quality of experience in the business. If the current applications all run smoothly with the implementation of voice, video and data across the switch infrastructure, then it is safe to say that the business is getting a great return on investment. This is only achieved by understanding the mix of bandwidth and manageability at an affordable price.
