text: **Note:**For the Tivoli Storage Manager client that is used by Content Manager OnDemand, 
  set COMPRESSION NO in the Tivoli Storage Manager client option file (dsm.opt for Windows or 
  dsm.sys for UNIX). Content Manager OnDemand objects are compressed before they are 
  sent to Tivoli Storage Manager for archival; therefore, compression by Tivoli Storage 
  Manager is not required.
