EMC does not support end-user install of RPMs onto vApp packages.  An enhancement request should be filed to have the rsync utility added to the vmutils package.
Part of Custom Property Tagging I need to send few files remotely using a script to SRM vApp Collector Server, i'm wanting to use rsync but observed that utility is not present in the vApp.  Is there a way I can install? Also i'm unable to run any rpm install command - is it blocked by EMC, if so - how can i get rsync installed. 
Can I install rsync utility on SRM vApp??
