I wan to run a backup script once per day but I don't want to specify a certain time, just once per day. I've read that the @daily cron attribute runs every day at 00:00 but i don't know if the receiving server will be up at this time.
Is it possible to configure cron
to run this script just once per day irrespective of the time? Or run the script until it succeeds and then try again the next day?
@reboot would be an option however the sending end might reboot several times per day in which case it would lead to unnecessary backups.
