To be fair, tape backups are very much ok as a disaster recovery solution. It's cheap once you have the tape drive. Bandwith is mostly fine if you want to read them sequentially. It's easy to store and handle and fairly resistant. It's "only" poor if you need to restore some files in the middle or want your backup to act as a failover solution to minimise unavailability. But as a last resort solution in case of total destruction, it's pretty much unbeatable cost-wise. G-Drive was apparently storing less than 1PB of data. That's less than 100 tapes. I guess some files were fairly stable so completely manageable with a dozen of tape drives, delta storage and proper rotation. We are talking of a budget of what 50k$ to 100k$. That's peanuts for a project of this size. Plus the tech has existed for ages and I guess you can find plenty of former data center employees with experience handling this kind of setup. They really have no excuse. |
