Consider Data Management
At almost every step along the way of your business pracitices and production process you will need to consider, plan for and execute some type of data management.
Any component you create in a digital format must be considered volatile and unsafe if it has not been duplicated, copied or backed up in at least two places. Three copies at all times is actually preferred.
Consider all of your files and raw data. Everything from outlines, scripts and storyboards to images, video and audio that was captured into digital formats as well as any graphical elements along with the project files for their manipulation programs.
We can never stress this enough: BACK-UP EVERYTHING DIGITAL IN TWO PLACES AT ALL TIMES
No hard drive is bulletproof. Never consider a single copy of a digital file to be safe from data loss.
