Starting today Apple let’s you download all of your data associated with your Apple ID.
The interface looks like this:
Most people will be choosing a copy of their data. You can select any option you like. I chose all of them. Apple will also ask you to select a size that’s comfortable for you. Here you get the option of 1GB,5GB,15GB or 25GB’s of data. I chose 25GB. Depending on what you chose, it’ll take longer to deliver the data to you. I chose everything and most data possible so my ETA is 30/05/2018.
