   Thanks for reporting this.

   We identified the issue. Attu 3.0.0-beta.6 sends the GCS option to milvus-backup as gcs, but milvus-backup 0.5.16 expects the GCS-compatible provider name to be gcp. Because of that mismatch, the backup process fails with:

   unsupported storage type: gcs
   

   This is an Attu configuration-generation bug, not a problem with your GCS bucket itself.

   We have fixed this in the codebase by mapping the Attu GCS option to the correct milvus-backup provider value and by defaulting GCS to HTTPS. The fix will be included in the next Attu release.
