Try this...

     I believe you will find you have
        "compression yes"
     and
        "compressalways yes"
     try setting
        "compressalways no"

     prior to a file being sent, adsm will pre-allocate storage space, if
     cache is on it will free cached files to obtain the space... if the
     inbound file exceeds the estimated space (ie a file that grows during
     compression) NO additional cached space will be freed to accommodate
     the file and you end up with the ANR0534W.  (as you pointed out below)

     WHY ? ? ?  to CYA if a client goes wild and to prevent dusting say a
     half terabyte of cached files due to one run away client ;-)

Have a client that gets a failed backup of a file and I find this message in
the Server log.

 ANR0534W                         c Copyright IBM Corp. 1993, 1997

If pool name is a random access storage pool with caching enabled,
it is also possible that additional space can be made available in
this storage pool by eliminating cached files.  When the server
allocates space based on the size estimate provided by the client,
it frees space occupied by cached files if this space is needed to
obtain the estimated space.  However, if the server later
determines that the file size estimate was too low, it attempts to
obtain additional space that is not utilized, but does not delete
cached files to do so.  If you believe that pool name contains
additional space occupied by cached files, you can turn caching
off.  To free space that is already occupied by cached files, use
the MOVE DATA command for the volumes in pool name.

I do have cache on the disk storage pool.  I can understand all of the words
above but can't figure out why this doesn't recover from the "wrong guess"
and adjust and then "backup" the file successfully!
