Cause

v19.4의 경우 #335554 같은 이전 핫픽스에서 코드 버그가 발생할 수 있습니다.

Resolution

다음 Avamar 플러그인 버전에 대한 최신 핫픽스로 업그레이드합니다.

버전 19.19의 Avamar Hyper-V VSS 플러그인 핫픽스 #337450 버전 19.4.100-124
용 핫픽스 #337285 Avamar Hyper-V VSS 플러그인 버전 19.8.100-83
용 Avamar Hyper-V VSS 플러그인 핫픽스 #337654 7.100-82

Dell 기술 자료 문서 211510을 따르십시오. Avamar: Hyper-V VSS 플러그인 - 최신 Hyper-V 플러그인 누적 핫픽스를 설치하거나 업그레이드하기 위한 자세한 절차를 위해 버전 19.4 이상용 최신 누적 핫픽스를 구성 및 설치합니다.
