Backing up Apple’s iCal & Address Book data
A good thing to do prior to first synchronizing your calendars and address books with .Mac or Zimbra here’s how to back up Apple’s iCal & Address Book data in Mac OS X 10.4.
Backing up iCal:
First, launch iCal and select File > Back up Database:

A window will appear in iCal requesting where to save the backup file to:

This will create a backup file of iCal:

After creating your backup file, store it safely on an external hard drive or burn the data to CD/DVD. To recover from your backup file, simply navigate to File > Revert to Database Backup and select the backup file.
Backing up Address Book:
In Address Book, choose File > Back up Address Book. This will create a database record of all your Address Book contacts. If you ever need to restore from the backup, just launch Address Book and select File > Revert to Address Book Backup.

[...] There’s also an option to reset your sync data, if needed. Before resetting your data make sure you have backed up your calendar & address book data. See Backing up iCal & Address Book data for help on this. [...]

I have a problem with my address book. I already have a copy of my database on a cumputer. I want to transport this copy by network to save it in an other cumputer.
I drag the copy on the desktop of the other cumputer. After, I open address book, I select “Revert to address book backup” and it doesn’t work. Actually, there is no database record in this computer, in this address book. Why the copy of my database, sent by network, can’t be revert to this address book backup???
NEED HELP!
Tanks you

Genevieve,
I had the same problem (I think) on my Macbook. Instead of reverting to the address book backup file, the computer would just ‘beep’ and show the same default addresses. I tried everything including deleting the preferences, etc. Finally, I ran Tiger Cache Cleaner and cleaned the cache (I just did a light cleaning), rebooted, and the problem was solved. Give it a shot and post your results.
Hope this helps!
