how to take least risk on rsync dir

[Patrick Hsieh]

Hello John Schaaf <john at kliek.xs4all.nl>,

After reading your mail, I wrote a little script:

#!/bin/sh

localdir=/backup/infotimes
localbkupdir=/backup/infotimes_bakup
remotedir=home::usrlocalinfotimes

rsync -av --backup --backup-dir=$localbkupdir --delete \
$remotedir $localdir



When I run this script, it does not make any backup under $localbkupdir.
Any idea?
