I guess you are using a clustering product which is not Legato-aware. The problem you are experiencing can be explained as follows :

- networker asks for a filesystem pertaining to a virtual host / ip
- the local client runs the save command which returns the physical hostname instead of the virtual hostname, as networker cannot interrogate your cluster - the data is then stored in the networker database using the physical hostname - the next time you run the savegrp, networker sees that there is no full backup for the virtual hostname (since in the database there is only the physical hostname), and asks a full backup again.

and so on, and so on..

I solved this problem for a customer by creating a shell script /usr/sbin/lcmap


That is an unncessarily complex solution when all you in fact needed was "save -c virtualhostname" in the backup command. This does work and is the recommended and supported solution.
