Good reminder to look at logs. Thanks
Cron log said it ran

Luckybackup log said it tried to run but with errors

I think I have to set up the ssh without a password again as there is a problem.
Question 1.... when a 'cron job' runs does it do it in the background or will it bring the GUI on the users desktop ?.
Question 2...... when you set up a 'ssh-keygen' and then send it to the remote machine, do you have to be logged on with the same credentials ?
eg, if I used user = 'pclinmike' on both machines , but what if I use user 'pclinmike' on one machine and user 'mike' on the
other, would that work as well.?
Question 3... why has using ssh changed my permissions ? also some of my programs do not work like firefox, this has happened on two machines now.

Using 'Bash' I get
chmod: changing permissions of `/home/pclinmike/tmp': Operation not permitted
[pclinmike@localhost ~]$
