Backup only if disk mounted
I use a daily scheduled backup of my User data to an external Firewire disk. Since I'm using a laptop and do some travelling on some occasions the disk is not available. On these days SD will launch, give an errormessage and stay open.
Is there some way to tell SD to only launch and backup if the disk is mounted? I know that thsi means some days will not be backed up, but that's OK. Do you have to use Applescript for this?
Thanks
