Do you keep work and personal separate? Do you use multiple providers like iCloud/OneDrive/Dropbox/Google Drive or do you stick to one? Do you do any type of auto-sync folders?

What's your process like? I'm curious on what people to find the most automatic and reliable solution for typical day to day with photos, documents, and their work backups. (Thinking more along the lines of your own side projects or things that you're more in control of, less on the corporate side that have imposed solutions and is managed by a team).
