2-2-1-1 Understand what the term 'backup' means, and why a regular
backup routine is important.Users access cloud-based
applications through a web browser or mobile app and the user's data is stored on
servers at a remote location.Table 1 below illustrates the typical maximum storage capacity of common storage
devices:
 
 Device   Maximum Storage Capacity
 External hard drive  Up to 2TB or more
 USB flash drives  Commonly up to 128GB
 DVD    4.7GB   
 CD    700MB                                                                                                                             
Table 1 Storage Capacities of Common Storage Devices 

Your backup copies should be kept at a separate location from the originals, in case of
a fire or flood for example.CDs and DVDs have limited storage capacity but are inexpensive; USB flash
drives are usually small in size and can hold gigabytes of information; external hard
drives are the most expensive option but can be used to backup your enti re hard drive
including programs and operating system due to their larger storage capacity.The benefits of
cloud storage are that it is inexpensive - often free, is readily accessible from a range
of devices, has automated backup and recovery systems, is ideal for collaboration
purposes, is more secure as backups are physically removed from original files, is
invisible - has no physical presence and allows for automatic updates of your files
across all of your devices.Cyber Safety  21

(www.dropbox.com), and Google Drive (accessible via your Gmail account) .Accidental deleting, corrupt hardware, natural
hazards such as fire and water damage, virus attacks, theft, loss, and many more.Accidentally deleting files typically places the files in the recycle bin, which can be
recovered easily enough, but if not, recovery can be a time-consuming task with no
guarantee of success.7 BackUp Manager Example

2-2-1-2 Recognise common backup devices: CD's, DVD's, USB
Drives, External Hard Drives, and be aware of different capacities.The easiest and most feasible way to back up your files is to copy your files
(documents, pictures, photos etc.) to CD, DVD, USB flash drives or an external hard
drive.Hard disks do fail from time to time and in the case of
equipment failure, recoveri ng data will require professional assistance and will be
costly.8 Cloud-based storage - Just Cloud (http://www.justcloud.com/) 
2-2-1-4 Use backup features on your computer, and understand what
it means to restore a backup.Users normally have a limited amount of free storage
space, when that is used up the providers charge a fee.8 below illustrates Just Cloud's sign-up service that enables access to your files
from anywhere:
 
Fig.Backup refers to making copies of your data for recovery in case of loss.A few minutes spent once a week is much better than
having to rewrite a month's worth of work reports, or losing your family photos, or
rewriting a whole term's project report.Most computers have their own backup programs; Fig.Fig.
