This might help someone in the future, so for the record here is how I have my backup routine setup:
I have two external FW drives with several volumes each. I like to keep these volumes unmounted so that they don't interfere. SD will auto-mount and then auto-unmount destination drives [but not source drives].
I run two backups every night:
- a smart update clone of my Mac HD
- a smart update of a volume named ARCHIVES which contains files that I don't have room for on my Mac HD (mostly media, photos, keynotes, etc)
5:00a Energy Saver set to wake up iMac
5:01a iCal alarm set to mount the volume ARCHIVES using an AppleScript (this is necessary because ARCHIVES will be a source volume)
5:02a SD scheduled to start ARCHIVES backup
5:04a SD scheduled to start Mac HD clone
When the Mac HD clone is finished, it runs a shell script to unmount the ARCHIVES volume and then it sleeps the iMac.
Scripts used:
iCal alarm AppleScript:
do shell script "BDISK=`/usr/sbin/diskutil list | awk '$3==\"ARCHIVES\" {print $6}'`;/usr/sbin/diskutil mount $BDISK"
SD shell script:
#!/bin/bash
BDISK=`/usr/sbin/diskutil list | awk '$3=="ARCHIVES" {print $6}'`
/usr/sbin/diskutil unmount $BDISK > /dev/null
Here is where I got the scripts:
