Redesigned console experience

Cloud Backup introduces a redesigned console for on-premises file backup, on-premises NAS backup, ECS file backup, OSS backup, NAS backup, and CPFS backup. The data-source-centric interface centralizes backup data management within a single account, across accounts, and from replicated sources, with per-resource views of backup history, jobs, and restores.

This update streamlines backup and restore workflows with a more consistent management experience.
