Something like: define interface web-servers { # don't back up more than one web server at a time use 1 kbps } define interface database-servers { # don't back up more than one database server at a time use 1 kbps } define interface misc-servers { # try to back up two misc servers at once # 1xxx is found out by trial and error use 1xxx kbps } in disklist: web-1 ... web-servers web-2 ... web-servers db-1 ... database-servers db-2 ... database-servers misc-1 ... misc-servers misc-2 ... misc-servers misc-3 ... misc-servers misc-4 ... misc-servers The above worked most of the time. Every once in a while I would get more than I wanted running at once, but it worked well enough. -- Christopher McCrory To the optimist, the glass is half full.
