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

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!

Comments?
