Question

Syncing iTunes library between two computers and one backup server...

Asked by: rcoast

Now that we are DRM-Free...

I have my computer and my wife's. I run VISTA, she runs XP.

We have a fileserver running Win2003

I want exact copies of the iTunes library everywhere (on these three machines) and I want it to sync automatically and I want it to show up in the library automatically.

Let me explain...

I buy a song, it downloads to my machine. Automatically it syncs to my fileserver. Automatically it is synced to my wife's computer and automatically when she opens iTunes, the new song is discovered.

If my wife buys a song, I want to see it too, in the same manner.

THe first problem you may run into with iTunes and your exisitng Library is DRM.  You cannot Authorize two concurrent computers for the same song.

For music without DRM this is possible to do.

You will need to get robocopy (just google it)

Use your backup server or NAS to hold all songs

use robocopy to synch the two computers with the backup server or NAS's iTunes Library.

I can use RoboCopy, but it doesn't do a compare... my library is 100GB+ and I don't want to copy the entire thing each time.

BTW... I only have DRM-FREE music.

 

by: nappy_dPosted on 2009-01-07 at 17:16:55ID: 23321337

F both your libraries contain the same music at this present time, I would just dump it up to your server/NAS and then sync it back to the computers.  Test it out with some dummy files... Here is the command I would use

robocopy.exe /S MIR x:\sharedItunesLib "c:\documents and settings\userName\Desktop\testDir" /LOG+:c:\pathToStoreLogFile\file.txt

You can direct the default location of your library & your wife's library to the server, then share them and tell each installation of iTunes to look for shared libraries, that way all of the downloads will be stored on the server and each time you turn on iTunes will look for the shared library.  Also you wil have two separated libraries but iTunes will read both

xema makes a good point.

There are 2 issues to watch out for ..

1. The Music folder is going to be on all 3 computers .. with over 100Gb of music on each .. is this correct and what you want.  Unless you've both got Laptops and need all music on each computer this seems like excessive data duplication.  The fileserver is acting as a repository which you both contribute to, to create a joint Music library.
To keep the 2 PCs synched with the fileserver I'd recommend the Microsoft SyncToy application.  Easy to use, visual and it can be set to run as a Scheduled Task.
If you don't have laptops then it would make more sense to do as xema suggests and store the music and iTunes library for each PC on the fileserver.

2. iTunes does not automatically scan the Music folder and add new Music.  Instead you need to select the Add to Library item in the File menu.  You need to do this everytime you put new music in the iTunes Music folder.  So if you add music and your wife adds music then you'll both need to update your respective iTunes Libraries.
You could try this tool - iTunes Library Updater
