Why each option
When OneLake availability is enabled for an existing eventhouse, only new data ingested into the eventhouse from that point forward will be mirrored to OneLake. Existing data in the eventhouse at the time of enabling the feature is not automatically copied.
OneLake availability applies to the eventhouse itself, not specifically to new databases added to it; the focus is on newly ingested data within the enabled eventhouse.
Existing data in the eventhouse is not copied to OneLake when the availability feature is enabled; only newly arriving data is mirrored.
Data will be copied to OneLake, specifically new data, once the feature is enabled.
Both new and existing data are not copied; only new data ingested after enabling the feature is mirrored to OneLake.
When OneLake availability is enabled for an Eventhouse, only data ingested into the Eventhouse *after* the feature is enabled will be made available in OneLake. Historical or existing data in the Eventhouse at the time of activation is not backfilled.
