View Full Version : How to? Separate OS/APPs and Users to separate drives?

Purchased SuperDuper and made my second backup. My computer is a MDD g4 d867. About to replace original startup drive with a superfast replacement at suggestion of Mac Gurus. My computer needs some speed to use PS CS2 (photoshop) and it was suggested that I shoud separate my users from the applications and operating system to a different drive and just leave the os and apps on the speedy startup drive. My question is how to do this without screwing up permissions/directories (not sure if i am using the correct vocab) AND also do backups?

Can I use superduper to do this? It was suggested I use CCC but I already bought this based on the reviews.

Well, I guess my answer is "I wouldn't do that". Instead, how about trying a Safety Clone/Sandbox, created on the fast drive?

Putting your User folder on a different drive is a configuration that's not widely seen, and can cause compatibility problems with certain applications. But a Safety Clone is more of a "temporary" setup like this. You'll basically create the Sandbox on the fast drive, and it'll contain the OS and some applications. You'll boot from it and that'll give you the speed, but your user files will remain on the original drive.

It's kind of the best of both worlds. You'll continue to back up the regular drive, because that's where your files "really" are.

Does that make sense? I think you'll find it a lot easier, and more maintainable!

I know there could be issues from doing this. I have read on a couple of forums (macgurus, macfixit, david pogue) that there is a way to separate the user files from the os and apps onto a separate drive. Accomplishes speeding up the startup drive only having to access the platters for one purpose and separatelyif there is a crash the os/apps can be restored much more quickly. (i think a partition could accomplish the latter)

I am trying to speed up photoshop cs2 for batch processing raw images. Ram is maxed out but the application and operating system is on a slow drive and also competing with the user files.

Is there a way to setup the drives in such a way so the apps and os are on the fast startup (with the users) but reference the user folders from a second drive. not sure if i am asking the original question a different way.

That's why I suggested a Safety Clone, which basically puts the apps and users on one, and the OS on another.
