Facing issue in Velero backup - Backup Volumes: <error getting backup volume info: gzip: invalid header>

[Shanky5554]

Dear team,
I am experiencing issues with Velero backups, encountering an error and also being unable to open the .gz files from the backups. My current setup involves using a Minio bucket for backup storage and Velero as the backup tool. Additionally, in our Kubernetes environment, we use Rook-Ceph as the storage file system. Could you please assist me in resolving these issues?

Velero backup completed with error :-
Phase: Completed
Warnings: error getting warnings: gzip: invalid header
Errors: error getting errors: gzip: invalid header

This means Velero CLI failed to download the backup result file from the backup repository. Please check whether you can download the backup's metadata files from the OSS manually.

Backup request "webapp-1" submitted successfully.
Waiting for backup to complete. You may safely press ctrl-c to stop waiting - your backup will continue in the background.

Please collect the debug bundle by the command velero debug.
And please also give the Velero install method and details.

Could you try with the Velero version of v1.13.2?
And the CSI plugin version is v0.7.1.

sorry for the late reply...solution for me is i was giving minio-web URL in place of minio-api in publicURL option in velero config.....(I added an ingress at https://minio-api.example.com (obviously substituting example.com) pointing to the minio api port and changed my publicUrl in velero to use that and now both the logs and the resource list in the backup details is loading.) and downloaded file open through shell.
below ticket help me to get the solution.
