Hi, I've searched all over the web, and in these forums, and still see a ton of confusion about how exactly Time Machine generates the daily backup from the hourly backups it created. I've seen postings on both sides of the issue, one arguing that it merges all of the files backed up in the hourlies into the daily (so all files present at any point in the day are present in the daily), or that it just selects one of the hourlies and uses that as the daily file. The former would make more sense to me, and be in more alignment with Apple's claims of "you're covered", but I can't find one definitive answer. Can anyone comment on their experience, or point me to a source that describes in detail how Time Machine creates the daily backup? Thanks.
