Data storage and back up
Having copies of your data saved in a different location or device keeps it safe in case anything goes wrong with your computer, laptop or mobile device. Deprime solutions ltd offers best solutions for that and how to.
Causes of Data Loss
A computer crash occurs when a computer stops working as a result of any software or hardware failure. A crash makes the computer unusable, either because it is “frozen” (still powered on, but not responsive) or has the computer has turned off completely and will not operate. Any computing device, such as a smartphone, tablet, game console, or even an automobile has the potential to crash since they all have both hardware and software that are required to keep them functioning. As a quick refresher, the software includes your operating system and programs (or apps) installed on your computer, while hardware includes the physical parts of your computer, such as the processor, memory, hard drive, etc..
Computer viruses are actually small programs that have the ability to replicate themselves and then spread throughout your system in many ways. This is usually done without a user’s knowledge. After a Virus has infected a system, it will usually trigger itself in some sort of fashion. It can launch annoying pop-up windows that repeatedly place messages on the screen or It can deny the user access to data files and even change user system configuration settings. In advanced stages of infection, a virus can cause major damage to a system as it can corrupt files and render them unreadable. It can even start deleting files as well.

Physical Computer Damage–
Laptops and mobile devices are sensitive and are easily damaged if dropped or have drinks spilled on them. Computers also are susceptible to damage from the cause such as fire, water or electrical faults or surges. These are just but a few examples of how computers can be physically damaged
Laptops and mobile devices are sought after by thieves and cannot always be kept secure whilst traveling or at public venues. Computers can also be stolen at home during the home invasion.
These are most common reasons for data loss and why one needs to save data
How to Save Data
External Drive backup
Saving data to a separate location makes far more sense, and can be easily done if you have an external hard drive, or a large-capacity pen drive /stick(flash disk) to back up onto.
- Can be accessed at any time and does not require Internet connection
- The user is in control of the backup – Access and availability to the backup are regulated by user i.e. user decides when they want to back up, how and where they want to use it.
- It cheaper since it’s only one-time payment for the purchase is made and no monthly or annual payments needed.
- However, this method is only as secure as the device you’re backing up to. When saving your files on physical devices, your backup device needs to be kept in a different location than your computer, and can in turn fall victim to damage or loss.
- In addition, despite your best intentions, you may forget to copy your files as often as you should, leaving a large amount of recent work unprotected.
Cloud Backup/Online Backup
Files stored online are safe from damage your computer, and if something goes wrong with your machine you will still have remote access to your information from any computer with internet access. This means files can be quickly and easily restored to your computer from a secure online server.
- Files can be accessed anywhere so long as the is Internet access hence one does not need to have the backup device to access their backup.
- The access is determined by Internet access. If the user is in a remote area without reliable Internet access then the will not have access to the backup.
- Since the data is online the is a risk of data being hacked
- The data backup is regulated and maintained by a third party and hence user has to work within the limits of the agreement.
- The bottom line is that if you value what’s kept on your computer, it’s wise to take steps to protect your information from sudden loss. Work can be redone, but the loss of cherished files like family and travel photos is permanent.
- Many users regularly back up their files to their computer hard drive, but in the event of a total computer breakdown, this will not protect the information. Saving data to a separate location makes far more sense, and can be easily done if you have an external hard drive, or a large-capacity pen drive to back up onto.
