"""fc3h: backup_* knobs on import_settings
|
|
|
|
Revision ID: 0018
|
|
Revises: 0017
|
|
Create Date: 2026-05-24
|
|
|
|
Adds four columns to the singleton import_settings row:
|
|
- backup_db_nightly_enabled (default False — opt-in)
|
|
- backup_db_nightly_hour_utc (default 3)
|
|
- backup_db_keep_last_n (default 14)
|
|
- backup_images_keep_last_n (default 3)
|
|
|
|
server_default ensures the singleton row is backfilled in place
|
|
without an UPDATE statement.
