A website's domain name is registered with Cloudflare (and transferred from its domain name registrar), so that Cloudflare becomes responsible for serving content from that domain. Through caching and private high-speed links, Cloudflare ensures high availability and reliability from storage.
How does a CDN like Cloudflare work?Ĭloudflare leverages DNS ( Domain Name System) so that content requests come to Cloudflare's servers. One solution to ensuring performance and availability is to route requests through a CDN ( Content Delivery Network) such as Backblaze's Bandwidth Alliance partner Cloudflare, taking advantage of Cloudflare's performance and the free data transfer between Backblaze B2 and Cloudflare. Many customers have expressed interest in hosting static data for their website (ranging from minified Javascript applications to multi-hour 8K video) because of the security, reliability, and affordability of Backblaze B2 storage. If you would like to allow Cloudflare to fetch content from a public Backblaze B2 Bucket, see the KB article on using Cloudflare Workers to fetch content from a public B2 Bucket. Somehow that just doesn’t seem right to me.This article explains how to use Cloudflare Workers to serve data from a private B2 Bucket.
Now 15 bucks isn’t a lot, but as the repo grows so will this bandwidth usage and eventually I will probably be paying multiples of that just for running backups ( besides the actual storage cost). Now here comes the fun: for the past month they charged me $13.59 for bandwidth, at 1 cent per GB that means restic downloaded well over a terabyte just for running backups. My retention is set to -keep-daily 60 and this comes out to 13.252 GiB, so that’s maybe a few 100 MB churn per day. All my backups are tagged, so I can just run restic stats -mode raw-data -tag backup_mysql to get the total size used by just these dumps. Today I only ran one backup, for mysqldump'ing a bunch of databases. My current usage for today is $0.24 (25 GB), according to their billing panel (I think it’s just 1 cent/GB).
My problem lies with the Download Bandwidth they charge you for. I have about 5.5 TB of actual data so the bucket size seems about right. File Lifecycle: Keep only the last version.Some stats straight from the Backblaze panel: Maybe I just figured it wrong, but after running backups on a regular schedule my B2 costs are quite a bit higher than I expected.
