[Zope-CMF] Using XRon to backup my portal

[Jeff Ross]

Hi. I'd like to use the xron product to backup my portal on a regular basis.
I'm using the following Xron DTML Method:
_________________________________________________________
Content-type: text/plain

<dtml-call expr="PARENTS[-1].manage_exportObject(id='bws')">
_________________________________________________________

My portal id is 'bws'. This code works when I click on the "Trigger" link,
but when I schedule the task to run, it doesn't work. Any ideas?

Thanks,

Jeff
