Backup. It’s something most computer users – let alone artistic types – never think about, at least not until after it’s too late. Trust me, once it happens to you, it will never be forgotten. Perhaps I can convince you to never have to go through that by recommending you start your backup system now.
All that precious time spent creating, tweaking, and perfecting your masterpiece is well worth a few measly bucks and a bit of effort (which will be automated once it’s all set up) to ensure you don’t lose those hours of hard work.
