Backblaze B2 how to pick cloudflare CDN?

[ninjanner]

I am testing uploading to backblaze B2 and can download for free id using cloudflare CDN

Here comes the dumb question, I have never downloaded or exported anything out of B2 yet. How do you select a CDN. How do I make sure I select cloudflare.

Not sure how that works when I click on restore with duplicacy

How to download without fees from from Backblaze B2?

They don’t have a CDN. But transfers between members of a bandwidth alliance is free B2/Cloudflare Partnership Offers the Lowest Cost Media Serving Platform. So you can egress to cloudflare for free. How much does it cost you to egress from cloudflare — depends on your relationship with cloudflare.

Once I have my cnames set up , I am not understanding how to put bucket link into duplicacy GUI

Current when I set it up , the bucket auto populates when I put the key details in.

Is this because I hit that green button ? Assuming I just need to paste the entire private link in the bucket name vs hitting that green button that auto populates the bucket name ?

Did you read the comment I’ve linked to and links from there, specifically this one:

Feature Request: support custom B2 download URL in WebUI

Just wanted to post an update on my own progress. I finally got around to trying my branch with the web UI. I replaced the command line binary and updated the storage URLs in duplicacy.json to use the b2-custom://b2.example.com/bucket format. I ran my scheduled tasks and restored around 200 MB of data. No data was charged against my B2 account and I could see the spike of data in the CloudFlare interface. @gchen let me know if I can provide any assistance in your testing or if you want any chan…

You can create another B2 storage in WebUI for restore-only,. pointing to the same place, and then replace the URL in the duplicacy.json

Also, ensure you use paid Cloudflare account, I don’t recommend trying this on a free one, it would be a violation of their ToS

I did see that comment, but was confused as it looked like they where editing code in the GUI to test that out. Now I understand, create an new storage and name it something like restore, then edit that JSON and put the CDN name in its place with the bucket named appended on it.

thanks for stepping me through it !
