Keep Mount Point


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


                                                                         =
                          =20
 Yes     Specifies that the node must retain the tape mount point during =
the entire session.       =20
                                                                         =
                          =20
 No      Specifies that the node will release the tape mount point if =
policy definitions cause data=20
         to be stored in a disk storage pool after storing data in a =
sequential storage pool. The  =20
         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.
