In Pure1, the ability to simulate snapshot policies—particularly when assessing the capacity requirements and impact of enabling SafeMode—heavily relies on historical telemetry data. Pure1 uses the data from existing snapshots on the FlashArray to calculate the environment ' s daily data change rate, as well as the deduplication and compression ratios specific to those workloads.

By analyzing the footprint of existing snapshots, Pure1 ' s analytics engine can accurately project the future storage capacity required if you were to change your snapshot frequency or extend the retention period (for example, locking them down for 7 to 30 days under a SafeMode policy). If a FlashArray does not have any existing snapshots, Pure1 lacks the foundational baseline metrics needed to simulate and forecast the capacity impact of a proposed snapshot policy.
