Whither Backups
Once, Strata sourced a RAID system for a client without explicitly checking how backups would be done. She was shocked and dismayed to find that the vendor claimed that backups were unnecessary! The vendor did plan— eventually—to support a tape device for the system, but that would not be for at least a year. Adding a high-speed interface card to the box—to keep backups off the main computing network—was an acceptable workaround for the client. When purchasing a storage system, ask about backup and restore options.
