Scaleway backup

[cloudron_jf]

Hi,

My Scaleway backup keeps failing with this error:
box:tasks updating task 64 with: {"completed":true,"result":null,"error":{"message":"Backup endpoint is not active: Error listing objects. code: undefined message: HTTP: undefined","reason":"External Error"},"percent":100}

cloudron-support --troubleshoot shows everything green/OK

I have tried deleting and recreating the backup in Cloudron, also the bucket in Scaleway. API key is set up and active in Scaleway

curl https://s3.fr-par.scw.cloud works
curl https://s3.fr-par.scw.cloud/cloudron-backup-jf gives same access denied message.

Hello @cloudron_jf and welcome to the Cloudron Forum

Please share your backup site configuration for scaleway so we can take a look to rule out obvious errors.

Hello @cloudron_jf
Did you just recently upgrade to Cloudron 9?
Try to open the backup site configuration and just press save once and try again.
If this does not work, the used token should be incorrect.

[cloudron_jf]

It was a fresh install of Cloudron 9 only last week.

I tried the open/save thing above. It got to about 58% complete and then failed again with the above. All I can see in the bucket is cloudron-testfile so I believe the token I am using is correct?

Hello @cloudron_jf
Can you please provide the full backup log of that failing backup?

[cloudron_jf]

Unfortunately I deleted that backup and the log is gone, but here is the new backup log.

Any update on this at all?

[james]

Hello @cloudron_jf
What Cloudron version are you using?

[cloudron_jf]

I'm on 9.0.18

BTW a backup config on iDrive e2 works

Did you ensure that the IAM policy attached to your api token in scaleway has access to your object storage?
See: https://www.scaleway.com/en/docs/iam/api-cli/using-api-key-object-storage/

[joseph]

On scaleway, I tried to create an API key as admin and that does work. Are you using specify IAM settings? The whole UI is quite complex and has many options like AWS. Easy to get things wrong.

I can't reproduce this problem either. Most likely this is an IAM set up issue but if not @cloudron_jf please contact us on support@

I'd guess this was due to Cloudron's small default part size. I think Scaleway has a limit of 1000 parts per bucket.

@cloudron_jf try increasing part size.

[cloudron_jf]

@james Yes, I have a policy set up with storage "ObjectStorageFullAccess" permission. This policy is set up against the API key for the bucket.

[cloudron_jf]

@girish I still am unable to get this to work with Scaleway

Have you tried that?
