Backing up your data is now more crucial than ever in light of the global ransomware attacks like WannaCry and Petya that had happened earlier this year. The attacks mainly takes over a victims' computers, encrypting their files and then demanding the payment of a ransom to restore the affected files and also, it is no guarantee if the ransom is paid you will get all your data back. Hence, attacks like these may cause data loss. 
However, data loss can be a common problem because of various reasons ranging from computer viruses, hardware corruption, natural disaster or theft. Think of all the documents, files, photos and videos that you wouldn’t be able to recover. That’s why backing up your data is so important. Backing up your files gives you some protection against accidental loss of data, file corruption, hardware failures, virus attacks and even natural disasters. 
What is ‘Data Backup’?
‘Backing up’ simply means making a copy and archiving your computer important data so it may be used to restore the original after a data loss event. The backup copy can then be used if your original copy is lost. The copy should be kept at a different location in a secure environment.
What should you back up?
Basically any data that is important to you. At the very least, you should make copies of any documents or data that you can’t easily reproduce, such as your confidential documents, work or school assignments, photos or even your media collection. Alternatively, you could perform a full backup of all the files on your computer.
Where should you save the data?
You could save your backup on an external hard drive, or removable disks such as DVDs or USB drives. Make sure your backup is physically separated from the computer in case of a fire, flood or theft. Another option is to use cloud-based storage – this means saving your files somewhere on the Internet. The disadvantage of cloud-based backups is that it can be much slower, especially if you have a large amount of data.
How often should you make a backup?
Backup your critical data regularly. It is recommended to backup daily, but it depends on how often your data changes. Set a regular schedule for backup, so it becomes a habit, and it’s easier for you to remember. 
Don’t forget to backup your mobile devices too!
You should also back up your mobile devices regularly. Important data may include your contacts, notes, messages, photos or videos. iPhones & iPads can be backed up to iCloud or any computer with iTunes. For Android or other mobile devices, backup options may depend on the manufacturer.
