Chris is worried about storing all his stuff in the cloud. If the cloud goes down, will he lose everything? Leo says that storing in the cloud is practical because we use multiple computers and as such, he'll need to have a central storage area for all of them to contribute to. But the downside is that if he loses access to the cloud, he'll lose access to the data. That's why having a local backup is so important.
Leo advises getting into the habit of exporting his data locally and then saving them to an external hard drive. He can do that with Google Drive and Google Photos. He can also duplicate his backup to multiple services including Flickr and Amazon Cloud Storage. That way if one goes down, he'll have another.
