Quantum is certainly highly ranked as far as Backups to tape go.
Backing up SQL Server direct to tape will generally take a while. As far as speed and deduping, there are several more viable options for SQL Server. EMC has a solution of backing up to a grid using their RAIN technology which dedupes as well.
But with SQL Server, I still prefer to backup to file utilizing something like SQL Backup, or using RedGate Backup or LiteSpeed. Then do your backup to tape or to a grid. This provides a two-tier solution and can help in recovery.
