The savegrp report doesn't show anything out of the ordinary, it does mention 
that the cluster is owned by a particular server, but I have the 
pathownerignore file in place so it goes past that.

There's only one dns forward and reverse record for the virtual name.  I am 
however running into index issues because it registers under the physical 
client name so I will put the save command in.  Thank you for that tip.

Hey Chester,

Does the savegroup completion report give any reason that the backup has been 
promoted from an incremental to a full

Also in your client definition, under the save command do you specify something 
like "save -c <virtual cluster name>" (this is normally the same name as the 
client definition name) so in the media db and file indexes it registers the 
backup against the virtual node and not the physical machine that the instance 
is running on

Another reason that I have seen this happen is when your DNS is not 100% 
correct, we have had cases where there are multiple forward and reverse entries 
for the one IP address, and its caused similar behaviour, unfortunately there 
were application reasons for this DNS oddness and I think I resolved it by 
placing all of the entries under the clients alias field

I tried to keep it simple, when it ran fulls everyday I put in the overrides.  
Whenever I look at it while it's backing up it shows "full" instead of "incr".  
This is a backup of a clustered server, backing up the drives through the 
virtual name and using "curphyhost" in the storage node field.

I would try to keep the setup as simple as possible and not use overrides for 
this one.  I see no reason for it, you've got a weekly cycle, which can be set 
by a vanilla schedule "i f i i i i s" or "1 f 1 1 1 1 s".

2.  Why do you think it's a full backup everyday, by looking at client index 
which says "full" everyday, or judging by a savesets' size?  If index says 
"full" everyday - go through all your settings, sometimes needlessly complex 
settings masquerade the error.  Maybe try to blow all yoursettings and create 
fresh.  If index says "incremental", but size is same as full - look at your 
client.  Are you by any chance backing up a readonly FS?  What kind of client 
is it?
