Storage and Backups
In this month’s blog, we will be discussing storage and backups. We will discuss ways in which you can store data and why it is important to do backups.
This month’s wise words are:
GPU (Graphics Processing Unit) – A programmable processor which is used for rendering all images displayed on the monitor.
CPU (Central Processing Unit) – The computing part of the computer. Also called the “processor,” the CPU executes the instructions and performs the calculations and logical operations.
Motherboard – The motherboard is like the brain of the computer. It houses the CPU and is the centre of what makes a PC work. All hardware is run by the motherboard and power is allocated where it is needed. the motherboard communicates and coordinates the components to work with each other.
PSU (Power Supply Unit) – This unit supplies the computer with power from an external power source which can then be allocated by the motherboard. The correct wattage must be used to ensure the system works.
What is storage?
When talking in IT terms storage is the act of keeping your data in a secure location that you can access readily. Files in storage should be the working copies of your files that you access and change regularly.
Types of storage devices
Usually, a storage device is found within your computer whether that be a laptop desktop or mobile device. These are called internal storage devices and usually hold the core files to run the computer such as the operating system (Windows), antivirus etc. But, your personal files are stored on these storage devices too. Examples of these are HDDs (hard disk drives) and SSDs (solid-state drives). These are designed not to be removed and are fixed into the machine. If attempting to remove, great care should be taken so as not to damage the hardware. Otherwise, you may find the data corrupted and unreadable when you try to use it again.
This type of storage is exactly as described, external to the computer and removable at any time. These devices are commonly used by those who have more data than the internal storage can store alone. This is usually the case in businesses such as photographers, architects and graphic designers due to the size of photos and drawings that take up more space.
Examples of external and removable storage are HDDs, SSDs, USB flash drives and CD-ROM (although this form of storage is no longer common). These devices are expected to be removed so usually come with some form of protection. Usually, a rubber or plastic coating around them to absorb some impact or a protective case to keep them in.
Care should still be taken with these devices, they are more durable than internal storage when in their protective casing but they are not indestructible dropping them may still result in the drive breaking and the data being corrupted or unreadable. USB flash drives should be considered as temporary storage as these devices are more prone to corruption and failure.
Cloud storage is where the data is stored in what is called, “the cloud” or the internet in common language. The physical storage of this data spans multiple servers (sometimes in multiple locations), and these servers are typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the servers secured, protected, and running.
People and organizations buy or lease storage capacity from the providers to store user, organization, or application data. This option is often more cost-effective than buying storage devices over a short period of time and is an effective way of backing up data.
Consideration should be carefully made as to where your data is being kept. If it is not on UK based servers then data protection laws may not protect your data from being read or stolen.
Backups are copies of files that are separate from the storage device on the computer. The idea behind a backup is that if data is deleted, corrupted or stolen, the data from backups can be reinstated on the internal device. Therefore, data can’t be truly lost as it is stored in multiple locations, meaning there is little chance of all the data being lost. This is essential for both business and private users.
Lost data can cost companies a lot of money. For example, losing prospect and client information that will cause you to be unable to effectively communicate with your clients. Project information, research data and other examples add up to many thousands of pounds in time and potential lost income.
Approximately 50% of companies that lose their data do not re-open. Private individuals could lose data, which could mean losing photos of loved ones and memories that cannot be replaced.
The types of devices used for backups can be either External/removable storage or Cloud storage.
