Aimed at new and existing Amazon Cloud Drive users alike, the service will cost as little as $11.99 a year.
Unveiled on Thursday, the new feature will be split into two tiers -- one for backing up and storing photos only and another for backing up all types of digital files from MP3s to documents and movies.
The latter Unlimited Everything Plan will require a $59.99 yearly subscription while the Unlimited Photos Plan will come with an $11.99 annual fee. However, from March 26, US customers can sign up for a three-month free trial of either storage plan.
"Most people have a lifetime of birthdays, vacations, holidays, and everyday moments stored across numerous devices. And, they don't know how many gigabytes of storage they need to back all of them up," said Josh Petersen, Director of Amazon Cloud Drive. "With the two new plans we are introducing today, customers don't need to worry about storage space."
