Symptoms

Fuld sikkerhedskopiering er fuldført. Trinvis sikkerhedskopiering af individuelle VM er fuldført. Udførelse af trinvise sikkerhedskopieringer af mere end én virtuel maskine (VM) mislykkes dog.

På den sekundære node kan vi se disse fejl i logfilerne (normalt i mappen C:\Programmer\avs\var):

2020-04-21 11:04:10 avtar Error <41439>: Using invalid token:5ba93c9db0cff93f52b521d7420e43f6eda2784f

Cause

Hyper-V Resilient Change Tracking (RCT)-omfang var i den tokenanmodning, der blev sendt til Data Domain. Hvis der er for mange RCT-omfang, mislykkes DDR-tokenanmodningen.
Avagent-softwarerettelsen deaktiverer inkluderingen af RCT-omfangene i tokenanmodningen, da de ikke er nødvendige.

Resolution

For at løse dette problem.
  • Opgrader Avamar Server til version 19.4.100-124 eller nyere
  • Rettelsen er inkorporeret i Avamar version 19.4 og nyere softwareudgivelser

Additional Information

Hyper-V-sikkerhedskopieringer kan stadig mislykkes, selv med avagent-softwarerettelsen anvendt på alle klyngenoder. Hvis det er tilfældet, kan andre problemer bidrage til problemet. Disse problemer som f.eks. java-processer, der holdt op med at reagere, eller DDRmaintlog-rotationsfejl på Avamar Utility Node kræver Avamar-supportundersøgelse.
