Ok, here is the history of this one as this will probably help someone give me an answer. The disk array failed on our DPM server that we use for disk backups so we got that replaced with new disks, got it up and running but the only thing we are now having problems with is some of the Sharepoint backups. They show as "Backup metadata enumeration failed" or "replica is inconsistent" the other day i managed to remove one of the share point servers from a protection group, I have tried to re add this server back to the group but it wont let me, it keeps saying "the data source cannot be selected for protection because it was previously protected as part of data source xxxxxxxx and has inactive disk or tape replicas ID 31086" It then says about remove the inactive protection, but I can not do this as it is not selected to be backed up anymore.
Thanks.
