 ### Backup Methods
 
-The container supports two backup methods:
+The container supports three execution modes:
 
 1. **`restic`** - Backup to Restic repositories (cloud storage, remote servers)
 2. **`local`** - Create compressed local backup files
+3. **`loop`** - Keep container running for external schedulers (e.g., Ofelia, Kubernetes CronJob)

+### External Schedulers with Loop Mode
+
+When using loop mode, you can execute backups from external schedulers by running the backup scripts directly inside the running container:
+
+#### With Ofelia Scheduler
+Ofelia can execute jobs in running containers using labels (see Docker Compose example above).
+
+#### Manual Execution in Loop Mode
+```bash
+# Execute local backup in running container
+docker exec <container-name> /backup_local.sh
+
+# Execute restic backup in running container  
+docker exec <container-name> /backup_restic.sh

+```bash
+# Execute backup in running pod
+kubectl exec <pod-name> -- /backup_local.sh
