Everpure FlashArray Protection Group snapshots provide near-instantaneous, write-order-consistent capture of Oracle RAC databases on ASM. The application-consistent Protection Group snapshot — hot backup mode or instance suspend — is the recommended default: it produces a clean, Oracle-consistent recovery point and handles multi-array databases. The crash-consistent workflow is a viable alternative only in certain situations, such as when a brief quiesce cannot be accommodated and Storage Snapshot Optimization licensing is already in place, or for lower-stakes reporting and dev/test clones.
Across both workflows: snapshot all database disk groups together in one Protection Group, never quiesce or snapshot the OCR / voting (GRID / CRS / +OCR) disk group, and never attempt an ASM disk-group freeze.
