So, I implemented this around December 15th of last year. This meant that as part of the idkfa database, I was storing the images that would be captured using this proxy mechanism. This meant that the idkfa database would grow along with the number and size of the images used.
Cut to a few months later. First, I run out of files on my backup server (you would think 45 million would be enough). I fix this, only to find that it was masking another problem: I was running out of space almost every week. I know I wasn't adding *that* much more information to the applications I was backing up, but *something* was killing my storage over time.
Turns out, it was this. Storing 89MB of information each day (GIFs aren't the most efficient format), this slowly ate through my 60GB backup partition.
I've now changed my backup routine to only store a week's worth of idkfa backups. Still, though. Small changes, vast consequences.
