Store your important information in at least two secure locations. For example an external hard drive and/or Google Drive in addition to your computer.
Keep updated versions of important documents in some kind of cloud storage (Google drive, etc.). Storing files in a secure location online allows you to access the data from anywhere, and avoids hardware failure that can be associated with external storage.
Use Google Drive to sync files between multiple devices. By syncing your data with Google Drive you will be able to access files from any device with an internet connection.
Be sure to use encryption for external drives to protect data
