I'm very frustrated I hope you don't mind asking for some help since I'm gettin zelch from Stuff shirt, even though people raved about how great Dave is.
That's unusual for Dave. He's normal
very helpful and prompt.
I'm trying copy my image files (first time) to an Ext Dr, which will be my primary Dr, since I only put Apps in my Int HD.
You boot to the OS on an external, but install and run your applications from the internal drive? It's your business of course, but why would you want to do that?
So I select Source DR and destination Dr, Using Backup -all files
Right, you want to clone the entire drive. That way it's a bootable clone that you can copy back to the main internal drive in case of any kind of disaster.
Erase Destination Dr, then copy files from Source Dr (at this point is irrelevant since its the first time) right?
Correct.
However, going forward is where I'm getting very confused.
If I'm trying to back up files from Ext Dr #1 (source) to Dr #2,#3 (destination)
During copy what would be the best setting SMART Update Destination Drs from Source Drive??
If you're going to clone the same source (drive #1) to two more drives, then you will be doing a full clone, same as the first one, even on the Smart Update option. Anything that's on drives #2 and #3 will be erased or added to as necessary to match the source drive. In the end, you'll have two drives/partitions that are identical to the source drive.
Somehow, I read that Smart Update will copy/delete files as necessary from the destination Dr outside the user files. So does it mean that I need to move all the source files to the"user folder"?
No, there's no need to move anything around. Here's what Smart Update does.
1) You make your initial clone. This will take the longest amount of time since it has to copy everything from the source drive to the target. Doesn't matter if you use the option to erase and backup, or Smart Update. It will take the same amount of time.
2)
After your initial clone is done, that's where Smart Update comes in. You select the same source and target drives you did initially. What SU does then is update the target drive to match any changes made to the source since the initial clone. Since all of the OS, program and user files are already on the target drive, it will usually only take 5 minutes or less for SU make the target match the source again.
The whole purpose is to keep at least one partition as an up to date clone of the drive you normally boot and run from. If you were to clone drive #1 to drives #2 and #3 as you plan, then you can use Smart Update to keep two up to date clones of your main drive going. Essentially, you would be creating a redundant backup.
Then if your main boot drive ever fails, all you have to do is replace it, boot to either of your clones and use SuperDuper! to clone
that information to the new drive. You can even do a "hot copy" with SuperDuper! Meaning, you can clone the drive you're currently booted to with it. Just be sure to leave the computer alone while it's running if you do a hot copy. Not a good idea to be changing what's on the drive at the same time you're cloning it.
