Bug Report
What version of Kubernetes are you using?
v1.30.4
What version of TiDB Operator are you using?
1.6.0
What storage classes exist in the Kubernetes cluster and what are used for PD/TiKV pods?
Not aplicable
What's the status of the TiDB cluster pods?
All running fine
What did you do?
Create a TiDB AKS cluster in Microsoft Azure, create a BackupSchedule yaml file.
set spec.backupTemplate.cleanPolicy field to -> Delete.
When the AKS cluster performs the cleanup JOB, the job fails, looking at the storage account, i can see that all files are deleted, but all the folders remain (empty), it causes the cleanup JOB to report fail state.
What did you expect to see?
The cleanup job finish succesfully.
What did you see instead?
The cleanup job fails.
It seems related to the rclone config for azure blob storage, please see: rclone/rclone#7047
The logs from cleanup task container:
Create rclone.conf file.
