# RollbackApplication
Mengembalikan aplikasi ke versi berjalan sebelumnya. Anda dapat memutar kembali aplikasi jika Anda mencurigai itu macet dalam status sementara atau dalam status berjalan.
Anda dapat memutar kembali aplikasi hanya jika ada dalam`UPDATING`,`AUTOSCALING`, atau `RUNNING` status.
Saat Anda mengembalikan aplikasi, aplikasi memuat data status dari snapshot terakhir yang berhasil. Jika aplikasi tidak memiliki snapshot, Managed Service for Apache Flink menolak permintaan rollback.
