The catalyst for considering disk-to-disk backup solutions is typically a tactical issue – the enterprise needs a faster and less disruptive means of backing up ever larger volumes of data. It is critical, however, to make storage purchases in the context of a backup strategy that meets business needs. Do not start evaluating solutions until a backup strategy that includes recovery point and recovery time objectives has been established.
Business Assessment Comes First
Info-Tech recommends that all investigation of disk-to-disk backup solutions be preceded by a careful assessment of business requirements for backup. This includes an assessment of the business value of what is being backed up as well as establishment of Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for various systems, applications, and data.
