Time Machine questions
Hi,
I'm ready to set up TM for my MacBook Air for the first time. I've read Apple's information about it and still have some questions.
First, can I use the Mac while Time Machine is backing up, or should I start the backup only when I won't be using the Mac for a while? How long does a backup typically take?
Next, it's not clear to me whether I can access files on the external drive I'm using with Time Machine. It seems like this is storage that's all-or-none--I can use it to restore files if there's a catastrophic loss of information from the Mac, but I can't (or shouldn't) go there to retrieve one particular file that was removed from my Mac since the previous backup.
How does the backed-up material relate to what I have stored on iCloud, that also appears on my Mac? I have more on iCloud than is on my Mac, because it has stuff from my iPad too; the external drive has space for what is just on the Mac, but not for all that's on iCloud. So this external drive will back up what's physically on the Mac, and not what's on the iPad, even though the iPad files "appear" on the Mac because they're in iCloud. Is that right?
Thanks for any light you can shed on this.
