Has anyone successfully set up Cloudflare R2 as their backup solution?
I am able to backup small virtual servers, but my backups error out as soon as the file size reaches more than a few hundred MB.
In the error log there are hundreds of gradually incrementing lines that look something like this:
Completed 57.0 MiB/307.3 MiB (10.5 MiB/s) with 1 file(s) remaining
The relevant part of the error log is this:
Completed 120.0 MiB/307.3 MiB (4.2 MiB/s) with 1 file(s) remaining upload failed: ../../../../tmp/.webmin/387023-/example.com.tar.gz to s3://example-backup/test/example.com.tar.gz
An error occurred (ServiceUnavailable) when calling the UploadPart operation (reached max retries: 4):
Reduce your concurrent request rate for the same object.
I thought this might be related to the chunk size (default 5M) but increasing this to 500M had no effect. Any suggestions?
