How many (server side) errors to expect?

New to S3 storage. Working towards a (vendor independent) backup solution and uploading/syncing a mere 1/2 TB. Have seen the following errors a few times already over the last 10 days, and was wondering: Is this what I should expect to see routinely (and accept)? Or is this my current S3 provider?

I suspect these are server side errors. Correct me if I am wrong.

Failed to copy: operation error S3: PutObject, exceeded maximum number of attempts, 1, https response error StatusCode: 500, RequestID: [], HostID: [], api error InternalError: We encountered an internal error, please try again.: cause(Write failed. Insufficient number of disks online)

and

Failed to cancel multipart upload: failed to abort multipart upload "[]": operation error S3: AbortMultipartUpload, https response error StatusCode: 404, RequestID: [], HostID: [], api error NoSuchKey: The specified key does not exist.

that is a server-side error. idrive uses minio.

that is the same error as you reported in your other topic, correct?

contact the provider, update us on their reply?

Indeed. The "NoSuchKey" stemmed from the initial issue with the provider. Sync then ran ok a few times yesterday. This morning the "Insufficient number of disks online". Provider hasn't responded to my first report but will try again.
Trying to find out if it's time to switch.

i have had to contact idrive a few times. i found their level1 techs was ok, but not great.
but when the issue(s) were raised to level2 techs, i got much better answers.

idrive is a stripped down version of s3 standard

in my case, i need confidence that in a disaster, i can quickly download the files. idrive transfer speeds can be slow.
for each location, there is a local backup server.
on top of that:

  1. keep recent backups, mostly veeam and 7zip, in wasabi
    in my testing, nothing is faster than wasabi. i have a topic or two about that. and they support sse-c encryption, full s3 policies, MFA delete and temporary session tokens.
  2. keep older backups, that i never plan to download, in aws s3 deep glacier, at $1.00/TiB/month

and i like hetzner storagebox, very good pricing and supports a number of protocols.
when using sftp, rclone can use checksums to verify file transfers.

I had two open support tickets with them. Never heard a beep. Asked whether they would be willing to put a hard cap on my ingress/egress/storage, so at least I couldn't incur additional cost if something goes wrong again - they declined. So I closed the account within the15-day-refund window.
