Backups may have the following error when using version 8.6.3:
"The following component is not installed on this computer: Back Links"
This is a defect. There should not be an error or warning logged, simply an Informational event. This occurs if the DC being backed up is not a Global Catalog server but the collection it is a member of has the following option enabled, 'When backing up Global Catalog servers, collect group membership information from all domains within the Activie Directory forest'
Create a collection for DCs that are GCs and a collection for DCs that are not GCs. Only enable the collect group membership option on the collection that contains only GCs.
This will be addressed in the next release of RMAD and RMADFE
