I have a fairly unique position at a charter school in Washington, DC: I work full time at the school filming teachers in classrooms to cultivate an archive best practices in teaching.
I am quite amateur in the field of videomaking, flying by the seat of my pants every day, and am now seeking out some best practices myself. One thing that I struggle with is backing up my videos as I have a lot of content stored up at this point. I tend to record anywhere from 1.5 to 4 hours of video a day on my Sony HDR-CX580V. The quality on which I record is "Long Time" HD mode (the lowest HD quality setting): 1440 X 1080/60i quality, AVC HD 5M (not quite sure what all of this means). All of this content is recorded on a 64GB Sony SD card.
Once I've finished recording, I then export the video file (from the compressed AVCHD format on the HD card) onto my 3TB Buffalo Ulta Fast Drive Station (which I have been super satisfied with). I export the file in 720p to maintain the HD content and not take up I do not store any of my videos on my laptop because I am using a Mac Book Air (clearly not the best computer for video editing but this is what we have the budget for). I also upload all of this content onto our Vimeo PRO account.
When I first began this position, I was given the following words of advice regarding backup:
"A video does not exist unless it exists in 3 places."
Every time that one of 64GB SD cards fills up, I buy a new one. This allows me to preserve the raw 1080p content should I need it in the future (for my purposes 720p is fine) and follow this rule of storing my content in 3 places: SD card, external hard drive, and Vimeo.
All of my SD cards are about full and I have 5 on hand now. It is getting fairly expensive to continue buying SD cards and I am wondering if I REALLY need to maintain this "all content exists in 3 places" rule. If you video experts think that this process is right on or excessive, please let me know. If you have any further advice about this process, I am VERY open to feedback and suggestions.
Thanks so much!
