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. The process of disk staging is controlled by the same software that performs actual backups, which is different from virtual tape library where intermediate disk usage is hidden from main backup software. Both techniques are known as D2D2T (disk-to-disk-to-tape).

- 數據緩衝技術(Disk staging)是一種利用了硬盤作為額外及臨時的數據緩衝技術,使要備份的數據在複製到磁帶之前,會先複製到緩衝磁盤。放在緩衝磁盤的數據會保留約一日或一星期,直至在背景執行的備份過程完成,才會從硬盤上刪除。 數據緩衝的過程由備份軟件操控,它亦是操控整個備份過程的軟件;這與的運作有所不同:在虛擬磁帶庫裡,緩衝硬盤是對備份軟件隱藏的。不過,這兩項操作都屬於D2D2T,意思就是「磁盤到磁盤到磁帶」。所以,D2D2T並不一定代表數據緩衝技術。 (zh)
