The business I work for has just acquired another business of a similar size. We're in the process of integrating IT systems and are faced with having two different data backup products in use. What criteria should we take into account when setting out to achieve one common data backup storage environment?
Take a step back and decide what you need to achieve with your
storage environment. Engage with the business to assess
recovery point objectives (RPOs) and recovery time objectives (RTOs)
, i.e., how much data is the business prepared to lose, and how long is it prepared to wait before it can be recovered?
Perform a gap analysis between your business requirements and the two backup environments. You must then determine if the gap can be closed to the business's satisfaction with either environment. You should also look at the longevity, supportability and ongoing costs of each solution. If one solution is retired in favour of the other, will it still be necessary to recover data using the old solution after it's been retired? If so, you must then determine for how long.
