Back-Up

With this system, you can use the recovered copies of files in case there is something wrong with the original one. It can happen during regular use, processing, or errors due to software and hardware issues. As a result, this will lead to data loss or corruption, making it inaccessible. In a business situation, this event can be costly.

What do you mean by backup? 

Back-up is a process of making a copy of your important data and putting it in a safe place. You can find a copy and recover it when the real data gets lost, deleted, or damaged. It can be stored on external hard drives, USBs, cloud storage, or other computers.

Regularly doing data back-up can give you peace of mind and security. Sometimes, you will not even realise that the files are faulty. It came from accidents like hardware failure, power cuts, viruses, ransomware, and more. You must always prepare to handle data loss or corruption. Both of these problems are different things. 

You lose data when you accidentally delete, overwrite, or damage a file. It can happen when a system crashes, due to broken hardware, or not saving properly. On the flip side, corruption occurs when the file becomes damaged or unreadable. The main causes are viruses, faulty software, or damaged storage media. 

Methods to back-up data

Essentially, you can create and save another copy of your files, including business documents and holiday pictures. As long as they are collected inside a computer and in digital format, you can do the back-up. Plus, you can do it manually and automatically, if the device supports this action.

Moreover, there are two ways to save your files. You can carry out with online or offline storage. Both of them have their advantages and disadvantages you need to know. Take a look at the explanation below for more details. 

Online

Also known as cloud storage, this is where most people are using these days. You can set it up quickly and much cheaper. This method allows you to back-up your files on the internet instead of your device. Then, you store the data on special computers or servers, such as iCloud, Google Drive, or Dropbox.

To make it work, this format requires an internet connection to do the back-up. Systems will upload and store your data in large buildings full of servers, called data centres. It allows you to access, edit, and share your files from any device, such as a computer, phone, or tablet. Here are the benefits and weaknesses of this service.

Benefits

• You will keep your data safe, even if your device goes missing or gets damaged.
• Create space on your phone or computer’s storage.
• Easier to collaborate on files with others through shared files.

Drawbacks

• Unreliable providers can easily steal your back-up data.
• You need an internet connection to upload or access the file.
• For larger storage, you might need to upgrade the subscription service.

Offline

Offline method didn’t require internet access, as the back-up files were held in physical devices. In other words, the data is stored “locally”. This means the data is inside a hard disk, SSD, flash, or drive. The difference from cloud storage is that the data will stay with you, with or without an internet connection.

People still use this traditional way for backups because of its safety, privacy, and convenience. The file is hard to access for hackers, since you didn’t send the file over the internet. Also, what makes it more convenient than cloud storage is that you don’t need monthly payments because you only pay once for the device. Here are some benefits and drawbacks of using this method.

Benefits

• Great for back-up in case of internet failure.
• Safer for sensitive data, like personal information or classified documents.
• Helpful when you want to use it in remote areas with weak or no internet access.
• Ideal for making large file copies. 

Drawbacks

• When your USB or hard drive breaks, your files can get lost.
• Difficult to share because you need to plug it into the device directly.
• Limited capacity.
