Philip Bloom mentioned, in his master class yesterday, a file utility I had not heard of before, one that seems brilliant to me: ShotPut Pro. This program will copy your media files from their source (camera card) to up to 3 locations simultaneously. Brilliant!
I think that always having an untouched copy of your original media files and a working copy of them is always a bright idea. This practice not only gives you the option of having an emergency backup of your files in case of drive failure or theft, but provides you with some measure of future-proofing your media files for later use—perhaps in projects using CODECs we don’t even have today.
I also use BackBlaze to automatically and continuously sync all of my data off site. The three important parts of that last sentence are: off site, continuously, and above all: automatically! BackBlaze is a steal of a deal at only $50 per machine per year for unlimited storage! I just do my work using my machines, and BackBlaze is always keeping my offsite backup up to date.
If you were doing professional projects, where setting up the shoot required a significant investment or was time sensitive (can’t be easily repeated, for example), using locally redundant copies of the original media and off site backups is essential!
