Every photographer should have a backup of all their files. Images, book keeping, contracts and agreements etc.
Yesterday I picked up this little unit from LaCie (pronunced la - see)that I plan to use a s my backup while shooting tethered to my laptop computer. Even though I keep duplicates of each image on my laptop' hard drive, I can't hep feeling that I need to safeguard against a catastrophic event that might take down my laptop hard drive at the worst possible moment.
Imagine having spent days planning, hours shooting and just before you pull up your files for editing, the hard drive bails. It won't spin up, or the whole things just starts to smoke. With an external back up scheme, your chances of getting the job done increases exponentially. I will probably get another in order to have multiple copies stored in different physical locations in the future, but this is a good start. I'm waiting until I upgrade my laptop before I settle on an additional external as the input ports have changed over time.
Ask me how much I would recommend you to have backups for all your necessary files and client projects. I'll tell you that crap happens, and you simply don't know when that might occur. Case in point, I have replaced 2 hard drives from my desktop computer. I did not back up all the files, unfortunately and lost many important files. I have since learned my lesson, and you should too.
This hard drive cost me just over $160 with taxes and will potentially save me thousands should a big problem occur that takes out my laptop drive. (or the entire unit gets stolen) I know with all certainty that it is a worthy investment. No hesitation. For a more robust backup solution, take a look on YouTube for a video by pro photographer, Chase Jarvis as he outlines the lengths he and his crew go to in the name of insuring the safety of their work >>> https://youtu.be/Y-6EQo6it7Y
