Hi all,

I've been using zsCompare for quite a while now (so long now that I cannot find an updated version) but only for small comparisons. Now I find that I need to compare my backups to boot drive. zsCompare exhausts its memory (perhaps in the middle of the night) when I run it overnight. Secondly, I've not found an update.

So, any suggestions for superior programs would be appreciated.

Thanks.

I truly don't feel safe fiddling with Terminal. Isn't there an app with a safe/civilian/user-friendly GUI?

You know, I should probably add this to TimeTracker sometime.

ls and diff?
What's unsafe about those terminal commands?

I found this a few weeks ago, but haven't tested it yet: DiffMerge

I used File Merge (which has a GUI) - you get it with the Developer Tools for free.

I was going to suggest FileMerge, too, but I ended up trying it first with a couple of Time Machine backups, and it just sat on "Initializing" for a really long time before I finally gave up and quit it. I don't think it's designed to handle directories of this size.

rsync is the best CLI option I know of for doing this. We backup terrabytes of data with it daily, it can be used to simply determine different files by running in dry run (-n) mode. You can output the results to a text file by doing this:

rsync -aEvn /source/directory/ /destination/directory/ > differentfiles.txt

Hee hee - you're probably right. I used it to compare two 400GB directories and while it worked, it did take almost two days to make the comparison on my Mac Pro

Have a look at ChronoSync. It may do just what you need.
