Sorunun temel nedeni, Data Domain ile PPDM arasındaki zaman farkının çok büyük olmasıdır. Bu durumda Data Domain'deki zaman, PPDM'deki saatten 15 dakika ileridedir.

connectionDescription, bu zaman farkı nedeniyle "-1383149567" negatif değerine ayarlanır ve bu da ddp_disconnect neden olur.

Saati senkronize etmek için NTP'yi hem Data Domain hem de PPDM sunucusunda yapılandırın.

Yedeklemeyi, Retention Lock Mode etkinleştirilmiş olarak yeniden çalıştırın.
