Closing lid and backup ok?

I was wondering, what if I close the line of my mbp while a Time Machine backup is going on - I assume that won't corrupt anything? Does it sleep too and then finish when you open the lid and it wakes up? Does it cancel the backup? Something else?

Thanks...
 
My MacBook Pro automatically backs up several times each night while asleep and connected to power.

Hmm. I think that is controlled by the Power Nap setting, which I have enabled. Mine does not seem to back up even though it says it should. Not sure why...

It shouldn't... The backups are also periodically verified for stability, but if you're concerned you can manually run a verification by holding option while clicking the time machine icon in the menu bar and selecting "Verify Backups".

Closing the lid doesn't just cut off power, it merely sends a notification to OS that lid has been closed. OS is free to finish whatever housekeeping it wants or needs to before sleeping.

I *don't* have power nap enabled which means when I shut my lid the backups pause. I regularly do backups that get interrupted like that many times. I've never had an issue.

Dumb question, but why take a chance? Didn't you have issues migrating data from your old machine to the new Mac because of a corrupted backup?

Oh I wouldn't do it on purpose, but the external drive is very quiet and I wondered if I closed it in a hurry with backup running and didn't realize it, what would happen, would there be an adverse effect.

The funny thing about corrupted backups is that you won't know about it, until you do a restore. I guess if its done accidentally, there's not much you can do about it, but I would be concerned, but that's just me 🙂

Next time I am going to do a migration I am going to take the time to do a full backup on a fresh backup, and verify it, first. It will be a lot less time than I spent lol. Plus, I am looking at Super Duper as a backup alternative for this instance, as someone recommended it..

I use Carbon Copy Cloner, which I prefer. I don't know about Super Duper but I like CCC's interface and the author keeps it updated. The last time I looked at SD, I didn't like the interface.

For new machines, I don't copy over the entire cloned image, just because the newer machine typically is on a different build number due to the new hardware. As I said in the other thread, my preference is to set up as a new machine, but everyone is different.
