The file handle is only capturing STDOUT, and the stuff that is showing up on the terminal is most likely being printed to STDERR. Adjusting the command line being passed to open might fix it: 
open( RSYNC, "rsync -az -e \"ssh -o Batchmode=yes\" --delete-after hos
+t:/path/to/dir /path/to/backup 2>&1 |" );

I think the  2>&1 redirection should work on most unix-style shells, but I'm not sure -- test that first.
