A Solutions Architect must create a cost-effective backup solution for a company’s 500MB source code repository of proprietary and sensitive applications. The repository runs on Linux and backs up daily to tape. Tape backups are stored for 1 year.The current solution is not meeting the company’s needs because it is a manual process that is prone to error, expensive to maintain, and does not meet the need for a Recovery Point Objective (RPO) of 1 hour or Recovery Time Objective (RTO) of 2 hours. The new disaster recovery requirement is for backups to be stored offsite and to be able to restore a single file if needed.Which solution meets the customer’s needs for RTO, RPO, and disaster recovery with the LEAST effort and expense?Read More →
