Check enabled volume backup schedules hourly and notify teams when no
execution occurs within the configured number of days. Expose the alert
threshold in the UI and API, with alerts disabled by default.
Route volume backup results and warnings to the appropriate Telegram
backup threads.
Expose DELETE for application, database, and service storage backup
schedules (with OpenAPI docs), reject storage deletes while schedules
exist, skip retention cleanup when no limits are set, and remove S3
archives using the execution’s S3 storage.
Add polymorphic volume backup scheduling for persistent volumes and directories, expose schedule management via API, and reorganize backup configuration and execution views.
