Rdiff-backup is telling you that the metadata it set on /media/ 
drobo/.../10.1.3/rdiff-backup.tmp.44 does not match the metadata it  
read from /srv/eda_tools/.../lmdiag

What version of rdiff-backup are you using? What are the permissions +  
other attributes of /srv/eda_tools/.../lmdiag ? Are you copying ACLs  
and extended attributes? (if you don't know, rdiff-backup -v4 can tell  
you)

What mount options are you using for /media/drobo ? What is the native  
filesystem of the Drobo? (ext3? FAT32?)

Frankly, it will be 1) faster and 2) eliminate these errors if you  
skip using NFS and install rdiff-backup on the Drobo directly. Search  
the Wiki + the mailing list archives for directions.

Something about your setup is mangling file metadata, and rdiff-backup  
won't let that fly.
