Mac OSX 10.6 Cron Job Not Running
This was fixed by changing the cron job slightly. It was changed from
*/2 * * * * /BackupScript/backup.sh >> /BackupScript/log.log 2>&1
to
*/2 * * * * cd /BackupScript && ./backup.sh >> /BackupScript/log.log 2>&1
There was some form of issue where the Cron job didn't know to execute the script, but the new version of it explicitly tells it to.
