Why Mac OS Extended (Journaled)? - RESOLVED
 

The SuperDuper! Users Guide states: "use Disk Utility to erase the drive...and use Mac OS Extended (Journaled) as the format."

Why Mac OS Extended (Journaled)?

Why not Mac OS Extended (Case-sensitive) or Mac OS Extended or Mac OS Extended (Case-sensitive, journaled)?

And do I really need journaling on a backup drive/partition?

Do the formats of the source drive and the destination drives have to identical?
What if I am trying to make the destination bootable?

thanks,
dave

Because the default file system for OSX is Mac OS Extended (Journaled). Journaling is, in general, always worthwhile. Case sensitivity is usually a big mistake to turn on, since some native applications will not work case-sensitively. Don't do it unless you really have to.

The formats do not have to be identical, no, but in general they are. Not sure what you're asking regarding bootability, though.

Really: DO NOT use case-sensitive volumes unless you really, really have to.

New here...I'm trying to clone the internal drive on my MBP to a new drive. Tried another app and had problems which could be related to case-sensitive. I'm going to try SD now. My internal drive is Mac OS Extended, Case-sensitive, Journaled. To be clear, can/should I clone it to a drive as Mac OS Extended (Journaled), w/o Case-sensitive? I.e. it's okay to do that, not have them be the same? Thank you!

Yes, you can do that, but you'll likely need to use Smart Update, since Erase, then copy will try to preserve case-sensitive when it erases.

The old drive was formatted case-sensitive, the new one is not. Are you saying that Erase then Copy will change the format of the new drive to be case-sensitive like the one it is copying from?

I believe it will, yes, since it copies the attributes on erase from the source partition. As I said, use Smart Update and it'll work.
