Description
How Immutable Storage Works
Baseline Data: Your current data that exists regardless of immutability settings
Immutable Period: During this period, snapshots cannot be deleted or modified
Accumulation Phase: From Day 0 to Day N (immutability period), all changes accumulate
Steady State: After Day N, old snapshots can be deleted, but new ones are created
Net Growth: If deletions < changes, storage continues to grow over time
Snapshot Frequency: More frequent snapshots require more granular change tracking
