50 is not a large number. What's the problem?

  50 tape backup drives is not a large number for less than a single rack of storage? Buy one rack of storage and two racks of tape backup for it? That seems... not great. Even outside of managing hundreds and hundreds of tapes.

  I think he means that you'd need 50 tape drives with the backup running simultaneously across all of them to run the backup in a day - fortunately that's not how backups get run, you generally aren't running full backups every time, you run a full then do incremental or differential backups starting from that point with periodic full backups. The point I caught from the article that most people are bypassing is that tape provides a fully disconnected and unreachable (by attackers) backup, where many online backup systems are using software and systems that may be reachable from the systems being backed up. In the worst case of a motivated knowledgeable skilled attacker that could mean an attacker having the ability to wipe backups as well as live systems.

    This is a good point. It really depends on so many factors what a good solution is for one's dataset.
