VM yedekleme oturumu günlükleri vProxy'de aşağıdakiler altında bulunabilir: 

/opt/emc/vproxy/runtime/logs/recycle/vbackupd/date (/opt/emc/vproxy/çalışma zamanı/günlükler/geri dönüşüm/vbackupd/tarih)
 

VM yedekleme oturumu günlükleri NetWorker sunucusu üzerinde de bulunabilir; ancak NetWorker sunucu günlükleri, jobsdb saklamaya (varsayılan 72 saat) tabi olur. Bu, işlem tamamlandıktan 72 saat sonra oturum günlüklerini sunucudan kaldırılacak anlamına gelir. vProxy günlükleri bu durumdan etkilenmez.

Bu sorunu gözlemleyen VM'ler için Değişiklik Blok takibini (CBT) sıfırlayın.
VMware belgelerine bakın: VMware vSphere sanal makineleri için Değiştirilmiş Blok İzlemeyi Sıfırlama (2139574)

Bu prosedürle ilgili yardım gerekirse ve CBT ile gözlemlenen sorunları araştırmak için VMware desteğine başvurması önerilir.
