Ditto not optimal for backup
Authored by: el bid on Dec 19, '01 03:22:51AM

I'm really uncomfortable about ditto -- it seems to be an under-maintained utility with the kind of bugs you just don't need in a backup tool. I'm also uncomfortable about the whole HFS+ thing, which doesn't sit at all well in the UNIX landscape (which is where we are these days). But I'm aware that this is an ongoing debate among the Mac community, and I'm not trying to fan any flames here.

Here's what I currently think is the best solution. Use the GUI Disk Copy tool for backup. Create a suitably sized empty disk image, copy your HFS+ bouillabaisse into it. You now have a bog standard file which you can back up to tape or whatever in the conventional way. It will probably compress nicely.

The interactivity required by this technique is a downer, but presumably a suitable Applescript could be constructed.

Anyone got a better idea?

Disk Copy not optimal for scripting

Scripting Disk Copy would be a great idea. Only one problem - Disk Copy isn't scriptable. Neither are many other standard OS X applications. If Apple is going to trumpet scripting (as they should) then they need to get their butts in gear and make more standard OS X applications scriptable.

But see man hdiutil...

Looks pretty good if it does what it says.
