Disk staging is using disks as an additional, temporary stage of backup process before finally storing backup to tape. Backups stay on disk typically for a day or a week, before being copied to tape in a background process and deleted afterwards.

Data is restored from disk if possible. But if the data exists only on tape it is restored directly (no backward-staging on restore).
Reasons behind using D2D2T:
