Abstract
Obtaining immutable snapshots in storage systems for recovery after corrupted data detection. The method includes triggering an immutable snapshot without forcing an active storage write cache to flush so that active write cache data is not contained in the snapshot. The method includes analyzing current active writes in the write cache to identify compromised writes. Triggering the immutable snapshot may be in response to detection of a corrupted data risk and may be in addition to scheduled immutable snapshots or at the time of scheduled immutable snapshots.
