 So make sure you've got at least local storage from, say, SanDisk or Western Digital, everything from a micro SD card to a thumb drive to a solid state drive to an external hard drive, which is high capacity. You can fit a ton of files in there for long-term keeping. Make sure it's connected to your computer and that you regularly back up your files. I set it to automatically do it. For example, you can download free Acronis files.
