How to back up IFS

 I have just started using the IFS root file system on our AS/400, V3R2.  
 Our backup software is BRMS/400.  The BRMS manual indicates that backups 
 of the root file system must be done in a restricted state.  Does anyone 
 have any good ideas to back up the root file system, without implementing 
 restricted state?
 
 TIA.
