- iCal
- Address Book
- Camino (bookmarks)
- del.icio.us bookmark file HTML
- Delicious Library
I post here not for others to use as-is, but rather so that you might glean parts that are relevant to your system/apps or adapt the whole thing or even add to it. Making frequent backups of this data is something you don't need to remember: simply open and customize as necessary in Script Editor, then save as an application (you can unclick the "Startup Screen" button so it doesn't ask if you want to run), and create an iCal event whose alarm runs the app.
Also note that:
- All save-as locations are as default. Yes, there are ways to script it so it creates or lets you choose a folder or folders, but I wanted it to be leaner than that.
- For a couple of them, it overwrites existing copies, and for a couple of others, it relies on there not being one there. Again, that's what worked best for me. You can adjust as needed.
- The URL for del.icio.us bookmark export needs to be customized with your username instead of "XYZ" -- or removed, of course, if you don't use del.icio.us.
- The delays coded into the script are what worked best for my system. Your mileage may vary.
- For you novice AppleScripters (like me), it's a really instructive script in that it shows how some apps for some scripts will play nice with the more descriptive script language, and other times, will only work with the "dumb" brute force code of tab, tab, tab, etc.
- Big thanks to the kind readers and coders at MacScripter who answered my questions.
- Of course, use at your own risk, no warrantee is expressed or implied.
[robg adds: This previous hint provided a solution for just backing up Address Book. As with that hint, you'll need to make sure that access for assisstive devices is enabled in the Universal Access System Preferences panel.]
