The document discusses strategies for storage in cloud deployments. It notes that cloud deployments create storage challenges related to multi-tenancy, availability, manageability, scalability, and elasticity. It proposes using application-aware storage with quality of service guarantees to address these challenges. Oracle storage solutions like the Oracle Sun ZFS Storage Appliance are presented as options to provide multi-tenancy, scalability, agility, observability, and high availability suited for cloud environments.

19. Case Study: Why a Copy on Tape is Critical
An example from March 2011 Gmail Outage
Users Gmail accounts were suddenly empty of any messages, but Google
promised the emails were safely backed up to tape.
"To protect your information from unusual bugs, we also back it up to tape.
Since the tapes are offline, they’re protected from such software bugs,"
Google explained.
