I can't see my r2 bucket list, and developer console shows 500 error at "https://dash.cloudflare.com/api/v4/accounts//r2/buckets?per_page=20" I tried re-login, delete cache but not worked, is there something to can I try?

Look 2 messages up...

There is an incident on R2.

Oh thank you. I didn't notice it. 😂

A good opportunity to test the robustness of things people have built I guess. The good news is uploading objects via S3 API works as expected. Just uploaded a couple tests on a system that replaces WordPress media library with R2 and uploaded objects land in the bucket properly. However deleting objects via S3 API is not working... so I expect to start seeing a ton of support tickets about that from users.

...and just like that, things seem to be working again. 🙂

Working for me again as well. Status report shows a fix has been implemented.

aws4fetch is pretty easy

https://developers.cloudflare.com/r2/data-migration/r2-migrator/ <- does this happen continuously? Gonna use it for a backup of an AWS S3 bucket if so.

I could be wrong, but I think the R2 migrator is one direction and wouldn't pick up edits/deletion of objects that happen in S3. So might not be a great solution for backup if you ever delete or change objects. Also I believe it's fetched from S3 when the object is requested... so if you are using R2 as a backup only, the objects probably are never going to be requested from R2 in a normal setup.

(never requested = never backed up)

I don’t think this migrator is a on-request one, seems to just be a one-off sync from S3 to R2

@digitalpoint thanks! Deletes don't matter, but yeah new files do need to be pushed over ideally.

I don't use it myself, but I know a lot of my users that need to migrate a ton of data love rclone. It let's you do "diff" transfers similar to something like rsync (it only moves changes). Although I would imagine the overhead of just listing S3/R2 buckets to get the list of objects could be substantial if you have a ton of objects in the buckets. Not sure what your setup looks like dev-wise, but if you are already uploading to S3, it might make sense to also upload to R2 at that same point in your code.

I actually got R2 sync working using Syncology Cloud Sync. AMA!

Interesting, it doesn’t work for me. I can list buckets in the setup step and then it fails.

I omitted

https://

from the server address and picked v4.

Same

This is my problem

Wait.. I figured it out! It works if you use the bucket URL for the target s3 URL (e.g. blahblahrandomuidformybucket.r2.cloudflarestorage.com) However it does NOT work if you do .r2.cloudflarestorage.com (via https://developers.cloudflare.com/r2/data-access/s3-api/api/)

Ah yes, nice! ❤️‍🔥

If I have some public assets in R2, is there any way to tell cloudflare how aggressively to cache it?

or is it all automatic?

you can control it the same way you'd control cache settings for any other asset on your zone, i.e. cache rules or page rules

so I have a cache everything rule for the subdomain

@Erisa | Support Engineer I guess I want "Edge Cache TTL" too?

any other rules that would be useful to get aggressive edge caching?

cache everything and edge cache ttl should be sufficient

you can tweak browser cache too if you think people might request it often in the same browser

@Erisa | Support Engineer hmm, I see

"cf-cache-status" of "DYNAMIC"

in the headers
