Create a Own Cloud Photo Storage Site in BackBlaze B2 Using Cloudflare and ShaerX

11/29/2020

I am using Imgur to store my Blog photos for a long time, before it was PostImage, PhotoBucket and ImageShack. After tested with BackBlaze B2 service, especially integrated with ShareX and connected to CDN service provider Cloudflare, I decided to give a BackBlaze a try as my photo site to store all my Blog screenshots and photos.

The free plan at BackBlaze is 10G and Cloudflare can be configured to work with it very well. Also ShareX screen capture software can auto-generate my own domain url for those photos. It sounds quite promising to use it as blog photo bed. There is cap limit for class b and class c transactions. But usually the limit is good for a small website like mine.

This post is a summary for all steps for installation and configuration.

Create and Configure Your BackBlaze Account

1 Sign Up an Backblaze.com Account. Free service is enough for this lab.

2 Log into Your Account and Create a Public Bucket

Here is an extra important step to set up your bucket. You will have to put one cache command into Bucket info: {"cache-control":"max-age=43200"}

43200 is seconds. This means Cloudflare will not re-fetch the resource from source (BackBlaze) in 43200 seconds

3 Upload a file to get Friendly URL:

For example: I got following url starting with f000.backblazeb2.com/file. You will need this url to put it into ShareX and Cloudflare

Friendly URL:: https://f000.backblazeb2.com/file/test1-51sec/2020/chrome_Xo1JBLaOgc.png

test1-51sec is bucket name. 2020 is the folder I created in the bucket.

4 Add a New Application Key

The application key will only show once, and you will need it to access your bucket. But you can create multiple keys later.

Both KeyID and Application Key will be needed to allow ShareX to upload the photos into this bucket.

Configure ShareX

1 Right Click ShareX icon, and select Destinations -> Destination Settings.. menu

2 Configure Backblaze B2 destination as show in the screenshot.

I put upload path parameter with year and month to organize the photos.

You will have to use custom URL with f000.backblazeb2.com/file/test1-51sec for now. Later, After we configure cloudflare to use our own domain for backblaze site, we can change this custome url.
