Sync! Network Home or Local Home?

I would like to be able to talk to everyone once more about what "Network Home" and "Local Home" mean. It's important that you, as users, understand these terms in order to make the proper choice when confronted with this puzzling dialog box.

It is incorrect to just assume that one of the options is the right option all the time.

The IDD computers "sync" to a user's "Network Home". This means: when a user "logs on" to a workstation, that workstation copies the user's home files from the server to the local computer. When a user logs off, those files are "synced" back -- files that are new and files that have changed are moved back to the "Network Home", replacing their older versions.

Now, this pop-up that is causing confusion only shows itself when files have changed on the server SINCE the last logon and download of the files to the local computer. Example -- user Frank logs into a workstation, and the workstation pulls Frank's Home from the network. Then, Frank opens a document and makes changes to that document on that machine. Now, before the machine does a "sync", he makes changes to that SAME document on his "Network Home" -- this can be done by using another computer to access his "Network Home" remotely, or can be done from the SAME machine, if he mounts his network home and changes the document there.

The Mac realizes that the document has been modified in BOTH places, and then MUST ask Frank which document version to keep -- the one on the "Network Home" or the one that was modified with the local copy -- the "Local Home".

In this case, if Frank chooses "Network Home" the local copy of his document is discarded.. If he chooses "Local Home" the network copy of his document is discarded, and replaced by the local copy.

Making the right choice here requires that Frank understands that he has modified his document in two locations, and knows which location has the changes he wants to keep.

"Sync Later" is the exception, and is ALWAYS the wrong option. Choosing "Sync Later" when logging off means that you are discarding ALL changes to your local documents, whereby much grief is created for the student, instructor, and administrator.
