Hello,
Sorry to dig up this discussion, but is there a solution about this problem ?
KB VmWare doesn't explain any solution http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2006849
I'm with Esx 5.0 and W2k8 R2 up to date and some of VM are not backuped due to this problem (event ID 12289)
If anybody could help me.
Regards
Damien
