Well, maybe. We use LTO6 to backup daily 60tb of data from production, so ten tapes a set. 14 dailies, 13 monthlies, and 7 yearlies. We are probably moving to a Data Domain solution; as in spinning disk; but the key to archival security is that backups are replicated between two sites that are geographically separated. space usage is minimized by compression and logic that can treat newer backups as extensions of existing data rather than duplicating all the data again. the big advantage is restore speeds. spinning up ten tapes which we write simultaneously because of speed needs is cumbersome and slow with restoring a single table taking nearly half as long as the actual backup. On a DD system its less than 30 minutes and with backups replicated to both centers a restore can be done to production that was saved from the dr site; we replicate from production to dr and only backup dr daily. the issue with tapes has been you never know when the one you need is gone bad until you need it. it is also not common to replicate tape sets but a disk base solution lends itself to easy replication and transmission from site to site. so I can see both solutions working side by side for some companies but for many the disk based backup solutions that are out have come down in price; most are leased; as storage devices have dropped. are biggest limitation still is the number of ports between system and backup devices.
