Hi Joe

This can be set in several ways.  One is to set an environment variable with 
the needed value.  Open the 'NetWorker Administration Guide', and search for 
'NSR_DEV_BLOCK_SIZE'; that will get you to the section that talks about this.  
The other way is to use the NetWorker administration program (either the 
'nsradmin' CLI or the NMC GUI) to set the value of the resource that controls 
this.  This didn't work in even fairly recent versions of NetWorker, but I 
believe it works in the latest (search the archive of this mailing list, or the 
other NetWorker resources on the EMC support site, for the details).

Hope this helps.

Hi Tim,

How do you manually set the block size tuning in 7.6.4/8.0?
