Important
On the Overview page of the subclient:
-
Turn on the BigQuery metadata entities backup toggle to include routines and external connections in backups.
-
Turn on the Enable time-consistent backups toggle to ensure point-in-time consistency by using the backup job start time as the reference timestamp for BigQuery exports.
