What Is Data Backup?
Data backup is one of the most important areas of IT and yet is also one of the most ignored. Data is essential to the smooth running of any business and is the essential start to any business continuity plan. ‘Backing up’ means making a copy of your most important files; this can then be used if the original copy is lost. Preferably the second copy should be held at a different location to the original and be kept in a secure environment.
Why Should You Back Up Data On Your Computer
Information or data on your computer could be lost, if:
- The hard drive in your computer fails
- The data on your computer is corrupted for a variety of reasons
- Your computer is lost or stolen
- Your computer is in a fire or other environmental event
- A virus infects your computer and deletes or corrupts your files
- Ransomware infects your computer and destroys all your usable files
Consider the inconvenience of having to recreate all of the information stored on your computer – how much of it is important to your academic or professional career – and how much of it might actually be irreplaceable.
What Should You Back Up?
Back up any information that is important to you. Consider not only the documents folders where you store the files you create, but also your Web browser bookmarks, contacts databases, and files stored on your desktop.
You should consider making a daily backup of assignments/documents you are working on.
Choosing what data to backup is a key start to making sure you have a copy of all your business critical information. You should think about what you would need to continue working if your PC were to be stolen/damaged. Clients address/telephone details, your account information, important documents. What about your Internet favorites and email addresses stored on your machine? How long has it taken you to collate all this information and what would happen if you couldn’t get it back once lost? These are the key things that you should be thinking about backing up.
It’s generally not practical or appropriate to backup copies of
programs you have installed, but you should always make sure you keep the installation disks or files. This way, you will be able to reinstall programs that you own, if your computer is reimaged or replaced.
