What do tiered storage and ILM have to do with DR?
That idea ties back into the topics of data growth, data control, data management and recoverability. Once you start categorizing your data based on criticality and recovery priority, it gives you an indication of your data segments. We have our high-priority data, we have our medium criticality data and we have our low restore priority data. This is a perfect opportunity, if you’re looking into doing tiered storage, to start dividing your data or using those categories to store your data. From a cost perspective, if your data is highly critical to your organization and you want to replicate it because it’s so critical you can’t afford downtime — that data probably belongs on your highest-performance, most redundant storage array. Conversely, if you have data that can wait because there’s really no rush to restore it, then maybe that belongs on your lowest tier or your lowest cost storage — or even potentially archived on tape. Tiered storage can complement DR efficiency, ensuring th
