Explain how to back up a computer in five steps.

Explanation:

1. Decide what to back up  

If you've stored anything valuable on your hard drive , you'll need to back that up yourself.

 2. Choose backup media  

You'll need to store your backup on a separate form of digital media - such as Go-ogle Drive, One  Drive for Business or an external hard drive

 3. Back up your data  

The backup method will vary depending on your choice of software and operating system Once that's done, schedule regular future backups.

4. Store it safely  

You don't want to lose your PC and your backup. So, be smart and keep your backup somewhere safe.

5. Check that it works

Errors and technical glitches can happen without you even noticing. You may only find out later when you actually need to use that data that something went wrong. Avoid the worry by checking your backups once in a while and confirming that the data is being properly backed up.
