You can use the MAXSIZE parameter on your storage pool definition. If
you do not have a next storage pool defined for the pool the file will
not be backed up. Try HELP UPD STGP at a command line prompt. Look at
this partial output below:

UPDATE STGPOOL -- Primary Sequential Access

Use this command to update a primary sequential access storage pool.

Privilege Class

To issue this command, you must have system privilege, unrestricted
storage
privilege, or restricted storage privilege for the storage pool to be
updated.

 maxfilesize
          Limits the maximum physical file size. Specify an integer from
1
          to 999999, followed by a scale factor. For example, MAXSIZE=5G
          specifies that the maximum file size for this storage pool is
5
          gigabytes. Scale factors are:
            Scale factorMeaning
                      K kilobyte
                      M megabyte
                      G gigabyte
                      T terabyte

     If a file exceeds the maximum size and no pool is specified as the
next
     storage pool in the hierarchy, the server does not store the file.
If a
     file exceeds the maximum size and a pool is specified as the next
     storage pool, the server stores the file in the next storage pool
that
     can accept the file size. If you specify the next storage pool
     parameter, at least one storage pool in your hierarchy should have
no
     limit on the maximum size of a file. By having no limit on the size
for
     at least one pool, you ensure that no matter what its size, the
server
     can store the file.

     For logical files that are part of an aggregate, the server
considers
     the size of the aggregate to be the file size. Therefore, the
server
     does not store logical files that are smaller than the maximum size
     limit if the files are part of an aggregate that is larger than the
     maximum size limit.
      Note:This size limit applies only when the server is storing files
           during a session with a client. The limit does not apply when
           you move data from one pool to another, either manually or
           automatically through storage pool migration.
