I'm trying to capture all output from a backup script I'm running as a cronjob. I save all of my backups in tar.7z files but for some reason only the output from 7z is being captured while the output from tar is not:

Specific code:

my $backupcommand = "tar -cvf - ".$directory."/".$seasonYear."*.html|7
+z a -mx9 -si ".$backupdirectory."/".$seasonYear.".tar.7z";
my $result = `$backupcommand 2>&1`;

[download]

The following is the resulting output in the terminal: 

user@server:~$ perl dailyscript.pl > testout.txt
tar: Removing leading `/' from member names
/home/user/backupdirectory/2011.html
user@server:~$

[download]

The following is the resulting output in testout.txt: 


7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18

Everything is Ok

I also tried the following and got the same result: 

my $backupcommand = "tar -cvf - ".$directory."/".$seasonYear."*.html 2
+>&1|7z a -mx9 -si ".$backupdirectory."/".$seasonYear.".tar.7z";
my $result = `$backupcommand 2>&1`;

Any suggestions on how to capture all of it?
