S3 backup location appends "/archive" to s3 bucket

Couchbase Server Kubernetes

I’m attempting to restore from an existing s3 cbbackup archive created by the backup service on a standard install CB 7.6 which was configured with the UI.

I’m attempting to restore it to a cluster on k8s using the cb operator. When I engage the restore - the error suggests that there are no repositories at the location - but the location has “/archive” which is not the location of the archive.

The existing archive in s3 has no path prefix - so it’s at the root of the bucket.

Is this a configuration error? How to correct?

Hey David,

Could you post your full CouchbaseBackupRestore resource here?

Ok - more information - I find that when I create a backup using the backup object in k8s - it automatically appends “archive” to the s3 URI when it creates the backup, so if I specify “s3://mybucket/someprefix” the backup ends up in s3://mybucket/someprefix/archive" - Thus when I want to restore from a backup archive created using the UI on a non-k8s CB cluster, looks like I’m going to have to append “/archive” to its name.

Unfortunately that does look like the case David.

Thanks,
