Some flopped, like Imation's Ulysses, which was intended to replace tapes and tape drives in tape libraries, bringing a whole new meaning to Virtual Tape Library. Others have seen it hard to find a market that's willing to pay a premium for a nice sturdy cartridge when USB hard drives are a dime a dozen.
Quantum's solution is to deliver cool, easy-to-use software. The first time a backup job is run against a new cartridge, it does a full backup. Since the software does subfile data deduplication, subsequent backups always are going to backup just the data that's changed since the last backup, relieving the poor SOHO user from having to choose between full, incremental, and differential backups.
For $750, a SOHO user could get started with the dock (Internal IDE or USB) and 2 160-GB cartridges so it could start a simple on-site/off-site rotation. At $300 a throw, GoVault cartridges cost almost three times the cost of USB hard drives, but with deduplication will hold a lot more.
It's not the right solution for backing up your media collection, but looks like a good solution for the SOHO user that needs a brainless backup of its accounting and CRM data.
