DefinitionOnline storage (オンラインストレージ) is a service where you rent, over the internet, storage space that a provider has set up on its servers, and keep your files there.
ExplanationYour files move from a local storage device to the far side of the network, so every read and write goes through a connection. Because they are kept apart from your devices, a broken or lost device is unlikely to cost you the files you stored.
AnalogyThink of storing your things in a rental locker in town instead of a closet at home. With the key, you can collect the same items from any station.
Memory hookThe Japanese ストレージ is simply the English word storage (a warehouse or repository) written in katakana, so the whole term reads as "a warehouse online."
