Back up /Users folder

I have two identical disks & I want one the target to be a bootable version of the source.

I want to be able to do:

1) one-off backups my current stable OS X installation to the target disk. This is my current stable OS X installation & that will remain until after I'm happy with whatever OS X update I've installed. This seems to be no problem with SuperDuper.

2) update just the User folder on the target disk - this ensures all my current data is backed up so that in emergencies I can reboot in the target disk with my last working OS but with my dats being at least reasonably current.

This I last thing cannot figure. The script keeps on on overwriting System files. I cannot seem to get it to just change the Users folders and ignore the rest.

Thanks for any advice.

We're always going to scan the whole drive, so you're not really saving anything by "skipping" the system files. Is there some reason you want to only update the User folder?

My advice would be to not do that -- to always use "Backup - all files". It won't take any longer (since the system files don't tend to change), and you'll end up with an accurate bootable volume, rather than a potentially mismatched one...

Hi dnanian

In an ideal world, yes, what you say is easiest & simplest. However, because Apple's OS upgrades seem to more often than not contain little 'surprises', I'd rather have a bootable backup where the Users folder is relatively up-to-date and the System files are at a stable point (determined by me).

Might I suggest a Sandbox instead? It's an elegant solution to exactly this problem.

I'll have another look at it when I get home, but from what I remember reading in the user guide, it's not really a backup solution.

BTW, notwithstanding my comments in this thread, SD is a lovely bit of software - I'm hoping that, if I can work out a simple solution to my particular constraints, I can stop using Retrospect (which I've used for about 7 years)

No, it's not a backup solution, but -- in combination with a full backup -- it is a solution to the "surprises buried in updates" problem.

By installing the system updates to a Sandbox rather than your main drive, you can maintain its pristine, "checkpointed" condition, while you check out the changes to the system. Once you're satisfied they meet your needs, you can apply those changes to the original volume.

Since your original volume is getting backed up (fully), your system retains its "known good" state... and rolling back from a "bad update" when using a Sandbox is a simple matter of restarting from the original volume: much easier than a "real" restore!
