Mac OS X application to sync a folder to another disk in real time

Question

Do you guys know any software that can reproduce the entire tree of directories under a certain directory to another disk and keep it update in real-time on Mac OS X?

A kind of mirror RAID, but instead of mirroring the whole disk I need to mirror just all directories inside one specific directory. As a mirror, it must update in real-time, I mean, as files are dropped, modified or created.

Any suggestions? Thanks.

This seems to do what you want.

Synk 7 does this. I haven't tried it, but have used Synk 6 (and 5) in the past with some success.

Answer 3

You should be able accomplish something like this using Folder Actions with Applescript/Automator.

Try this Automator Action: http://www.apple.com/downloads/macosx/automator/backupfolder.html

Save it as a plug-in and attach it to the folder. This article explains the process: "Fixing Automator Workflow Folder Action Plug-Ins in Leopard" at Peachpit (I can't post more than one link as a new user so you'll have to Google it).

If you're OK to spend a few bucks there is ChronoSync. It has a neat GUI, and was impressed when I tested it. However I'm not sure about real-time sync (it does scheduled sync, of course).

I stumbled upon this page listing backup software, and specifying the real-time detection the following softwares rise:

• Memeo Backup
• QRecall
• Synchronize Pro

I'll be glad to hear from your tests!
