Question:

How to use RSyncX on Mac OS X to migrate Mac files from an SMB volume to an ExtremeZ-IP volume

Answer:

When copying files to a Windows server using SMB, Mac OS X writes resource fork information into hidden files named “._filename” (the so called dot underscore file) on the shared SMB volume. When implementing ExtremeZ-IP, Administrators may want to merge the resource and data fork information and re-write the files to an ExtremeZ-IP AFP volume.

In order to merge the resource and data fork information for ExtremeZ-IP, a Mac OS X client computer needs to read the data from the SMB volume and write the files back to the server over AFP. This operation presents challenges when migrating a very large number of files to a new AFP volume in a reliable manner.

RSyncX is a file management utility available on Apple’s web site that can copy the data from the SMB volume to a new AFP volume in an automated way, verifying the data as it is copied. The following steps can be taken to migrate data using the RSyncX utility, which is available for free on Apple’s web site.

Migration Steps:

On the ExtremeZ-IP Server:

1) Create a new shared volume with the ExtremeZ-IP Administrator Application. Be sure you have enough disk space available for the files you are moving to this new volume.

On a Mac OS X Client computer:

2) Using Terminal, type the command: “defaults write com.apple.Finder AppleShowAllFiles true”. This command will allow previously hidden files to be copied by RSyncX. Restart the Mac after making this change so the changes take effect.

3) Download and install RSyncX available here: RsyncX

4) Mount the SMB volume you want to copy using the “Connect to Server” dialog box. For the server address, use “smb://servername/volumesource”. This is the source volume for the copy.

5) Mount the ExtremeZ-IP volume using the “Connect to Server” dialog box. For the server address, use “afp://servername/volumedest”. This is the destination volume for the copy.

6) Launch RSyncX, located in Applications: Utilities.

7) Select the mounted SMB volume from the “Select Source…” button or you can drag and drop the mounted volume onto the Source window.

8) Select the mounted ExtremeZ-IP volume from the “Select Destination…” button or you can drag and drop the mounted volume onto the Destination Window.

9) Next to “RSyncX Mode”, select “Update”.

10) Be sure “Run as Admin” is checked on.

11) Click “Synchronize”.

The files will be copied from the SMB volume by the Mac OS X client and rewritten over AFP to the destination ExtremeZ-IP share.

In addition, you can run RSync from the Terminal window. There are many other useful features of RSyncX. For more information, please see Apple’s web site and the RSyncX documentation. These features include the ability to log RSyncX activity, do byte-for-byte file comparisons and more.

Group Logic does not support RSyncX directly and does not warranty its use. Please be sure to review the documentation and test the application in advance of data migration. Additional detail on RSyncX is also available at MacOSXLabs
