backing up apps data : iPhoto, iTunes, Palm, bookmarks...

[pbarthelemy]

Hello,

How I am suppose to backup my application data ?
SuperDuper is Ok for 'brutal' folder backup but lots of apps hide/encode their data.

For instance :
- iTunes Library Folder : is it OK to backup it 'as is'? will purchased music be accessible?
- iPhoto Library : the folder has a weird structure, backing it up is OK ?
- where are the Palm, iCal, Address Book, Bookmarks... located ? How can I be sure my home folder contains all this ?Will I be sure I can restore to data on those apps ? ( especially the the Palm data ?)

A lots of question indeed....

Does anyone knows where to find documentation on all this ?
I guess what I am looking for is a per-application backup guide...
