Is a SD cloned drive "optimized"

[s_dup]

After a drive is cloned will the backup drive be optimized, including both the actual files and the directory? I figure the files will be (unless it's a sector by sector copy).

Previously, I used Disk Utility on a freshly directory optimized drive (using Disk Warrior) and I was surprised the directory of the drive with the new backup was 25% out of order.

It's not a big deal either way. Just curious.

You know, it kind of depends on how you define "out of order". The directory structure in HFS+ is pretty good at managing these things, and I don't think you're going to find a lot of difference between an out of order directory and an in-order directory, given that you're going to access these files in a relatively random fashion.

So... no. We just walk the files in the exact order they're presented to us by the system, and copy them as we encounter them. We maintain that "order", which is the natural order of the directory structure at the time the backup occurred... but that order doesn't necessarily correspond to DW's conception of "order".

From what you wrote, would you say that DW is useful only in case of a problem and that you do not need to use it to prevent anything. Sorry, not strictly related to SuperDuper...

In general, that's the way I use it, yes.

I run DW about once every 2-3 weeks...doesn't ever do any harm, and at least, makes me feel like everything is 'optimized.' By the way, Dave, Version 2.0 of SD is quite excellent! Thanks...

Thanks, brich! Glad you're liking it.
