<html><body><p><tt>> From: Stephan Graf <st.graf@fz-juelich.de></tt><br><tt>><br>> For backup we use mmbackup (dsmc)<br>> for the user HOME directory (no ILM)<br>> #120 mio files => 3 hours get candidate list + x hour backup<br></tt><br><tt>That seems rather slow. What version of GPFS are you running? How many nodes are you using? Are you using a "-g global shared directory"?</tt><br><br><tt>The original mmapplypolicy code was targeted to a single node, so by default it still runs on a single node and you have to specify -N to run it in parallel. When you run multi-node there is a "-g" option that defines a global shared directory that must be visible to all nodes specified in the -N list. Using "-g" with "-N" enables a scale-out parallel algorithm that substantially reduces the time for candidate selection.</tt><br><br><tt>-Wayne</tt><BR>
