Rancher backup helm chart

I have a question about the rancher backup helm chart, provided on Apps & Marketplace: Is it reasonable to install the chart using “No default storage location”?

Depends on what you are looking for/what you are trying to do. The documentation on this is here: Rancher Docs: Backup Storage Location Configuration

Hi Seb, you seem to be active on the topic, do you have any idea what could it be that the backup operator spits below error when I initiate backup (aws s3 storage set as a default location)?
Credentials are stored as a secret in cattle-resources-system ns. I did everything according to instructions on the link you’ve quoted.
Thanks in advance!
