[iTunes] iTunes Backup - Logic Used?

[James Hubbell]

> Hoping to get answers to some questions on a problem backing up my 
> iTunes Library.

> Tried to back-up to DVD's.  I got 6 to copy fine, the 7th timed down 
> to zero but never 'finished' and i force quit iTunes after an hour+ 
> vainly waiting for the spinning beachball to stop.  Dvd#7 did copy 
> tunes just like the other 6, however.  Is there any way to know what 
> caused the lockup?
>
> I used Apple's Article ID 93033 as my guide to do this - they instruct 
> one to make a New Playlist from Selection, having previously chose 
> 'select all' to copy my entire library to this New Playlist.
>
> My dilemma is some 8000 of my 11000 songs are now on dvd but I don't 
> know which haven't copied.
>
> What is the logic iTunes uses to copy?  I put my songs in earliest 
> date order before 'selecting all' but iTunes copied them some other 
> way that is not discernible.  I checked to see if it was Album, Artist 
> or Date driven but it's not.
>
> I need to know if there is a way to find the next song restart point.  
> Otherwise, I guess I'll have to do this all over.
>
> To that end, I will use a different approach on a redo.  I plan to 
> create a New Smart Play List forcing all 11000 tunes onto the list and 
> then sort them into earliest date sequence before burning.  If the 
> problem reappears, I should know what was the last song copied by date 
> into the library.  Will someone confirm this will work?
