I am a semipro photographer. One raw picture is >20M, and I tend to take between 500 and 2000 pictures for an event.
I keep all pictures. All of them. With the usual exceptions of the black ones or a very blurry ceiling.
My computer is also a laptop. I removed the useless DVD drive to host a second hard drive, only for the pictures. That gives me 750gb for pics.
I also have a 2TB external hard drive, and a general backup 4TB drive.
The workflow I use is as follows:
- I put all my pictures on my computer.
- Once transferred, I plug and copy all the new pictures on my 2TB, never removing anything from there, only adding.
- I then process the pictures, adjust them, do whatever needs to be done. I sort them in 3 buckets (deleted, meh, good).
- I copy the working copies for the good ones to the 2TB also.
- I delete the deleted/meh from my laptop, only keeping the good ones.
- I do a general incremental rsync backup of my laptop to my 4TB.
For me that's enough protection, I always have my "good" pictures with me on my laptop, and have access to everything else on my dump drive.
For fires and burglars, I also have a second encrypted 2TB at work. I can safely recreate everything else from that part...
So far it has served me well, and I haven't lost anything. I've been burned badly in the past after crashing a HD while doing a backup, and having 6 HDD failing me in the same year (yeah, lan partys will do that to your gear) so I am very anal about my data.
