Keep Mount Point


Select whether the node should retain the tape mount point for the entire 
session.


                                                                                
                    
 Yes     Specifies that the node must retain the tape mount point during the 
entire session.        
                                                                                
                    
 No      Specifies that the node will release the tape mount point if policy 
definitions cause data 
         to be stored in a disk storage pool after storing data in a sequential 
storage pool. The   
         default is No.                                                         
                    
                                                                                
                    



Maximum Mount Points Allowed


Enter a number from 0 to 999 to specify the maximum allowed resource usage by 
this node. A value of
0 specifies that tape drives cannot be acquired for storage operations. Data 
storage operations must
be contained within a disk storage pool and server operations like migration 
will manage putting
data on tape. A value of 0 does not prevent a retrieve operation from acquiring 
a tape drive. A node
is always allowed to acquire at least 1 tape mount point for the purpose of 
data retrieval. Entering
a value other than 0, limits the node to the specified number of tape drives 
and prevents the node
from monopolizing all of the available tape drives. This parameter is optional

Hi

 Can anyone explain to me very slowly  what the parameters: MAXNUMMP and
KEEPMP means when I define a new NODE.
The default is for MAXNUMMP  1 and for KEEPMP no

I backup first to disk and during the day migrate to tape, just my database
(Sap, Exchange ?) I backup directly to tape.
Did those parameters can affect performance ?.. I made a little test trying
to backup a same node (large client novell 5) once to disk and once to tape.
I got a very big difference on performance , to tape took a very long time.

Any suggestions will be appreciate.
