Cause

Sikkerhedskopieringer mislykkes på grund af manglende evne til at køre konsistenskontrol (ved hjælp af Eseutil) på Exchange-databaserne.

Resolution

Rediger datasæt for at aktivere indstillingen "Deaktiver konsistenskontrol (anbefales kun, hvis der er mere end to medlemmer i DAG)"

Som angivet i indstillingens navn skal du KUN aktivere denne indstilling, hvis dette er en Exchange Database Availability Group (DAG) med to eller flere noder i klyngen.  

Hvis dette er en enkeltstående Exchange-server, eller hvis det er ønskeligt at tillade overensstemmelseskontrol på Exchange DAG, skal du justere værdierne for følgende indstillinger i datasættet:

 

  • #IOs mellem pauserne
  • Varighed af pauser (ms)

Standardværdierne for begge parametre er 1000 ms. Prøv lavere værdier, f.eks. 500, og overvåg backupydeevnen. Juster op eller ned efter behov.
