Finding high-churn folders that drive Backblaze's bztransmit crazy

Your Mac's bztransmit is pinning a CPU core. Backblaze's status says a puzzling amount of "remaining files". The cause: some app is churning out thousands of tiny files — mostly caches — and Backblaze is deduping, checksumming and uploading every one of them, all day.

This is a walkthrough of how to find the offenders and exclude them, plus the measured results and the catch nobody mentions (exclusions fix the churn, but not all of the CPU — see the end).

// This is currently just a proof of concept. My OAuth usage requires setting
// a cookie client-side (server does not do this) after successful authentication.
// AIR runtime does not allow XHR to set cookie header so I had to use AIR's

// I imagine you can do the same thing but use jsOAuth.request or something in
