Back up to multiple locations on a regular basis! You can get a 1 terabyte internal hard drive
for about $100. Storage is cheap, there's really no reason not to back up important things.
Even if you periodically compress the files for storage or create backups using a program in some proprietary format, it's better than losing it all!
My data files are huge--videos around 4 GB each (total of about 600 or so videos). So I bought one external harddrive for my research (around $300) and getting a second harddrive to back up the first would have been very costly. And technically, I do still have the data, it's just in a format that needs to be converted before I can analyzed. It's really more time lost than actual raw footage. Still frustrating.
I should have been a little more specific, too. I need to get the files off of the computer I have them on and move them to another one. Everyone in the lab needs to use the same darn computer for data collection, so the portable allows me to perform my analyses elsewhere.
