Even though cloud storage is made up of many distributed resources, it acts as one entity and offers advantages like data redundancy and durability (th e sa m e d a ta is sto red a cro ss m u ltip le servers a n d is n ever lo st),a s w ell a s lo w er co sts. Cloud storage offers several advantages: Accessing Your Files on Mobile Devices and other devices like tablets and smartphones, and C you can access your files from anywhere. S 0 Securing Your Files Another advantage: your files are safe and they never get lost 0 even if your computer gets stolen, breaks down, or is destroyed. Your files always have a copy 1 in the cloud. Sharing Your Files: You can set up share folders and give access to other people who can use the files as well as add files for sharing. Collaborating: Allow you to collaborate with others on your files. You can have two people work at the same time on the same document. OneDrive automatically stores each edit and allows you to see the area of your document that is changed by the other person. 45 Restricted Restricted - ā«ļ»ļ»“ļŗŖā¬-ā«ļ»£ļ»ļ»“ļŗŖļ»£ā¬ Storing Documents Using Cloud Storage Solutions Cloud Computing Cloud storage solutions also automatically store revisions of the same document so that you can revert easily to an older version if the newest one is not what you want.
