Hello, we are trying to test the backup on S3 compatible device, and as mentioned [here](https://github.com/elastic/elasticsearch/issues/26604) it seems to be supported.
We have an issue concerning the certificate verification...is there a way to bypass that e.g. for lab testing?
If not we will have to:
1/ Import the certificate on the java cacerts like that:
keytool -trustcacerts -keystore $JAVA\_HOME/jre/lib/security/cacerts -storepass changeit -noprompt -importcert -alias s3-testcert -file my-self-signed-cert.cert
2/ Restart the servers.
Is that correct?
Best,
L.
