I exclude everything outside of my user folder, and also my Podcast folder in my iTunes folder...

I'm not worried about restoring the OS after a drive failure, but I don't want to lose anything in my User Folder...

I exclude Podcasts, because they are temporary files and are downloaded anyway.
 
I exclude any folder I know will end up taking up large amounts of data - movies folder, eyetv folder, Media Drive…like others above I generally only want the home folder which contains a lot of text files.
 
Anyone ever considered excluding the applications directory. The reason I say this is because.

1) your preferences and what not would already be saved under libraries
2) Restoring the application and it's components from a time machine backup might not only be incomplete but maybe lack proper permissions to function?

But least you could reinstall the program and have your preferences intact.
 
I don't use Time Machine (SuperDuper allows for bootable backups), but I don't exclude anything.
 
I exclude my downloads folder because I can always download all that stuff again.

This kind of stuff is why I exclude things outside of my user folder. I can always reinstall applications and things like that...
 
I exclude my ripped DVDs from my mobile backup disk that craps out at 120 GB. My downloads and podcasts change far too often so those are excluded as well.
 
I know this thread is kinda old, but I just got an external hd, and decided to start using Time Machine...I keep getting this error which causes the backup to stop:

So I excluded Macintosh HD/previous systems, will that harm anything? I have no idea what it does.

Thanks for any advice!
