attu b6 backup gcs failed

[cnangel]

Describe the bug:
When I perform a backup, I get the message "UNKNOWN: create backup storage client: storage: unsupported storage type: gcs".

The storage type is Google Cloud Storage (GCS).

Attu version:
3.0.0-beta.6

Milvus version:
2.6.15

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.
