Automount source volume

[Jack Mac]

I just created a scheduled backup from one unmounted external drive to a 2nd unmounted ext drive, but it failed: "The automatic copy failed because SuperDuper! could not locate the source volume"

I've used SD for years to automount the target volume, but this is the first time I ever tried to automount the source volume - is there a way to do this?

I'm using 2.6.2.

Thanks.

The source volume cannot be automounted -- only the destination.

Wow - thanks for the quick reply!

I assume I can get the job done by using the Advanced Options "Run shell script before copy starts", but I can't write a script and I haven't had much luck searching for a script I can use. Can you point me in the right direction?

Thanks

No, actually, you can't: those scripts run after the volume is mounted. You'll really want to keep the source volume mounted.

OK, so I'm getting closer, but I need more help.

I found a unix script that will automount and I created an AppleScript, and then set up an iCal alarm to run it just before the SD backups are scheduled. It works. This is the AppleScript:

do shell script "BDISK=`/usr/sbin/diskutil list | awk '$3==\"ARCHIVES\" {print $6}'`;/usr/sbin/diskutil mount $BDISK"

The thing I'm still struggling with is getting SD to unmount the volume after the copy. I used the unmount version of the same script in the "Run shell script after copy completes" but I got an error message. Here are the last three lines from the log:

| 12:19:21 AM | Info | ...ACTION: Running shell script Un-Mount ARCHIVES.scpt
| 12:19:21 AM | Info | ......COMMAND => Invoking After Copy shell script: /Users/~/Library/Scripts/Un-Mount ARCHIVES.scpt
| 12:19:21 AM | Error | sh: /Users/~/Library/Scripts/Un-Mount ARCHIVES.scpt: Permission denied

Any idea what I'm doing wrong? I thought the problem might be that the script I'm using has an AppleScript wrapper. If that's the case, I'm not sure how to create a standalone shell script. My limited scripting experience is all with AppleScript.

Thanks

Right. It's a shell script, not an apple script.

Since you can't eject a drive you're working with while you're working with it, perhaps it would be better to worst-case-estimate when this is done and eject with iCal?
