Cause

Avamar Garbage Collection kan mislykkes med MSG_ERR_DDR_ERROR efter en fejl i cloud-tilbagekaldelse forårsaget af DDFS-panik.
  • Hvis Data Domain-filsystemet gik i panik, mens filer blev tilbagekaldt fra cloudniveauet, efterlader den igangværende cloudtilbagekaldelsesproces nogle delvist tilbagekaldte sikkerhedskopifiler i "/data01/col1/avamar-xxxxxx/cloud-copy/<CID>/<BID>" vejviser.
Avamar Garbage Collection (GC) mislykkes derefter med MSG_ERR_DDR_ERROR. Garbage Collection kan ikke læse ddr_files.xml for sikkerhedskopier i cloudkopimappen på Data Domain.
  • Det er muligt, at den ddr.xml-fil findes i cloud-copy-mappen under <BID-mappen> , men når Garbage-samlingen læser ddr.xml-filen, finder den, at alle nødvendige sikkerhedskopifiler ikke er til stede, hvilket kan få GC til at mislykkes med denne fejl.
  • Dette kan skyldes, at ddr.xml mangler under mappen "/data01/col1/avamar-xxxxxx/cloud-copy/<CID>/<BID>" eller en af sikkerhedskopifilerne mangler.
