[Evolution] script tar backup

["Ariel Garcia T." <ariel garcia traba gmail com>]

Dears
Can anyone help me?
I need to backup evolution from a script because everybody here never
remember do it
In the script I inserted the following strings and it worked,
    evolution --force-shutdown
    tar
-cvzf /home/XXX/evolution-backup.tar.gz /home/XXX/.evolution/ /home/XXX/.camel_certs

When I try to restart the backup it  works from the terminal with tar,
but It does not from the menu 
Can you send me the correct tar string to do the backup so it can be
restored from menu?
Is there a possibility that the problem is the path?

In the next version. may be we can use something like
        evolution--backup
and that 's all 
Thank
Ariel
