Grsync is a rsync GUI (Graphical User Interface). Rsync is the well-known and powerful command line directory and file synchronization tool. Grsync makes use of the GTK libraries and is released under the GPL license, so it is opensource. It doesn't need the gnome libraries to run, but can of course run under gnome pretty fine. It can be effectively used to synchronize local directories and it supports remote targets as well (even though it doesn't support browsing the remote folder). Sample uses of grsync include: synchronize a music collection with removable devices, backup personal files to a networked drive, replication more...

Yes, it would be wise to compile your own copy of rsync, not only because the version included with any GUI program may not preserve all metadata, but because even the copy included with OS X itself doesn't preserve all metadata(!).

I'm on Lion, and here is is what the output from the system rsync reveals:

version 2.6.9
protocol version 29


64-bit files
64-bit system inums
64-bit internal inums

Now, here is the default rsync I use, which was installed via MacPorts:

version 3.0.9
protocol version 30


64-bit files
64-bit inums
64-bit timestamps
64-bit long ints

As you can see, not only is the bundled version out of date, but it hasn't had the required patches applied to insure metadata preservation. It's the same in Mountain Lion. The reason for this seems to be Apple's fear of GPL3 licensing, which applies to the newer versions of this and other programs. So if you want up-to-date BSD userland components, you need to install them yourself.

As I said, in my case, I used MacPorts to install rsync, but every other package manager available for OS X will have rsync, so use whichever one you prefer. You can also compile manually, or try extracting the copy of rsync that is included with Carbon Copy Cloner:

I agree with the comment above. It is important foe any mac Backup utility to be able to preserve Mac specific metadata. And the standard rsync does NOT often work well until it has been patched.

Does Grsync pass all the Backup Bouncer Tests?

As Grsync allows user to set specific rsync path in its preferences, you might like to compile your own up-to-date rsync.
You can follow theses instructions here (slightly outdated though) :

Or, you can try the excellent mlbackup :
mlbackup will install it's own rsync, precompiled for Mac OS X.
In fact, installing mlbackup is probably the easiest way to update rsync.
You will find it in /usr/local/maclemon/bin/

Best regards.

Unless this is using a custom version of rsync with numerous patches for Mac OS X metadata, this will probably cause data loss on Macs.

Version 1.1

reading truthhurts' comment, i was feeling a strong unease, not even recognizing at first where to localize it.

Was it the lack of a solid, neutral statement, was it the lack of own experiences about the product or was it altogether plus the formulas "...Unless this is using a custom version of rsync" or "... this will probably cause data loss on Macs".

Damn, does it cause data loss or does it not cause data loss - a question that is of some importance with regard to a backup/syncing app.

I think, however, that comments, publicly spread on software trackers, may no way disseminate pure assumptions.

This is almost the least respect we owe those who dedicate their time and efforts into software development - especially if it's freeware.

So, I decided to confront the dev with this comment and we'll hopefully know more then.
