A storage administrator is receiving reports that nightly backups are impacting system performance during the beginning of the business day. All servers are backed up via the network to a backup serve

A disk-to-tape (D2T) solution involves backing up data first to a faster disk-based storage, and then later writing that data from disk to tape. This decouples the backup process from the slower tape write speeds, allowing backups to complete faster and reducing the impact on production systems during business hours.

The problem statement explicitly indicates that network administrators confirm "plenty of bandwidth," meaning network speed is not the bottleneck.

Increasing the number of tapes available only provides more storage capacity, it does not improve the speed at which data is written to the tapes or the overall backup process.

Adding a second backup server might distribute processing load, but if the primary bottleneck is the tape drive's write speed, a second server writing to tapes would face the same underlying performance limitation.
