Price OCI File Storage including the snapshot capacity that daily change and retention quietly accumulate.
File Storage charges one per-GB-month rate for everything it holds, and snapshots are not free capacity: each daily snapshot pins the blocks that changed that day, so the retained volume is the daily delta multiplied by the retention window. At a 3% daily change rate, a fortnight of snapshots adds around 42% on top of the active data. Snapshot growth is the usual reason a file system bill is double what the active data suggests, and the fix is retention policy rather than capacity — halving retention halves that component immediately. Confirm the per-GB price in the Oracle Cloud cost estimator for your region, and remember mount targets add no capacity charge of their own.

snapshot capacity = active GB × daily change % × retention days; monthly = (active GB + snapshot GB) × per-GB price.
