Best Online Backup for Tiger...

I'm looking to get this service in addition to my daily backup to an external drive.

I've tried IDrive and after spending DAYS backing up about 45GB of my files, I find their software inconsistent and unreliable.... Carbonite seems great, but it's not Tiger-compatible. Dropbox seems great, but it seems like I have to manually drop files to be backed up, I don't see how I can schedule it to update automatically my backed up files.

So what else is there for us, Tiger users?

Thanks.....
