- Do not update your iPhone until you do this one thing.
- iOS updates aren't always perfect.
After one of them, people couldn't even make phone calls.
- If you don't do these steps, you could lose all the data
on your iPhone.
Open Settings and tap on your name
at the top of the screen, then tap iCloud and tap Keychain.
Make sure this switch next to iCloud Keychain is on.
Tap back to iCloud,
upper left hand corner of the screen.
Then, one above Keychain tap iCloud Backup.
Make sure the switch next to iCloud Backup is on.
Then tap Back Up Now
- If there's an issue, when you update your iPhone
and it says you need to restore it,
you're definitely gonna want to back up.
Otherwise you could lose all the data on your iPhone.
- Now you might be sitting there thinking,
I don't wanna back up my iPhone to iCloud
or I don't have enough iCloud storage space.
There is an alternative.
You can back up your iPhone using a computer.
If you have a Mac running Mac OS 10.15 or newer,
you'll back up your iPhone using Finder.
If the Mac running 10.14 or older,
or if you have any PC, you're gonna use iTunes.
- Let's do it.
- All right, get my lightning cable here.
There we go.
Under Locations in Finder on the left hand side
of the screen, you will see the name of your iPhone here.
And if you're doing this for the first time,
make sure that you tap Trust.
When this Trust This Computer pop up up appears.
Tap Trust here.
And the center of the screen, Backups.
Click the circle next to Backup All of the Data
on Your iPhone to This Mac.
And we recommend checking
off the box next to Encrypt Local Backup.
We sure do.
This is the number one mistake
people who use their computers to back up their phones
make is not checking this box.
Not because of the security thing, which is important
but because if you don't, it doesn't back up Keychain data,
which means that you will lose the passwords that are saved
on your iPhone, which could be a real pain in the butt.
- So now the backup is starting.
If you choose not to encrypt the local backup,
you can click this Backup Now button.
There you go.
It's how to do it in Finder.
Backup is now complete
and you'll see last backup to this Mac today, 2:00 PM.
- All right, enough about Mac users.
Let's show some love for the PC users
and the older Mac users that run iTunes.
Here, we have a Mac that's running Windows.
Also the battery's dead.
First step, open iTunes.
So we just saw a pop up about a new software version.
We don't need to do that.
I'm just gonna tap Cancel, Install Icon for Windows,
Remind me later.
Totally get to that.
Tap this phone icon that appears to the right of Music,
sort of at the top left of the screen.
It's very similar where you can encrypt a local backup.
Just tap Backup Now to back up the phone.
Let's talk about some really important questions
that people ask us all the time.
Let's go back to the previous screen.
And the question is
how do I see which backups are in iCloud?
This is really important
for people who might have other older backups
they don't need that are clogging up space.
So tap on Backups and then tap on This iPhone.
And it's gonna break down
what's in this backup for you.
You can also go to the bottom and tap Delete Backup
if it's an older backup
- We just backed it up.
And I noticed that 1.1 gigabytes
are Player Unknown Battleground Mobile.
That doesn't need to be in there.
- That doesn't make any sense at all.
1.1 gigabytes?
- Yeah.
- [Speaker] Gigabytes. GB.
- It's unbelievable.
So if you see something in here
that's really large that you don't need,
and maybe just go ahead and turn that switch right off.
- Just like with iCloud on a phone,
if you've been backing up your Apple devices
for a long time, you can end up with lots
of old big backups that take up a lot of space
in your computer.
So I just want to touch on how to delete those backups.
It's trickier on a PC, go figure, than it is on a Mac.
David's gonna love this.
Come down to the Search bar here at the bottom.
Type in %appdata%
and then hit the Return key.
Then go to Appl Computer, Mobile Sync.
That makes sense.
Backup and there's that backup folder.
- Wow, just so easy.
- It's just so easy.
On a Mac, it's easier.
Go ahead.
Unplug this from the PC.
- All right, you're the boss.
Well, there's this nice big Manage Backup buttons
- [Speaker] Right, buttons.
- [Speaker] Backup button.
- Backups button.
I'm trying to click on it.
- [Speaker] There we go.
Holy (beep). There's a perfect example
of a problem that somebody might wanna fix.
- I've been waiting for this moment.
That's why I've been saving all these backups.
- [Speaker] We're gonna see how much data David could save
by deleting old backups.
- Let's see, 115 gigabytes.
So let's say I don't want this iPod 2013 backup.
Two finger hook on that.
Just click on Delete.
- Delete. Trivia.
Can you restore an iPad
backup to an iPhone and vice versa?
- I think it's a trick question.
I think sometimes some of the files, yes,
but not all of them.
- Correct.
Is that correct?
- Yeah, well, the answer is yes,
but some files won't transfer.
- Here's another important thing to keep in mind when
there's a major iOS update like iOS 16 or iOS 17,
a lot of people are trying to download it
all at the same time.
This can sometimes overload Apple servers
and leave your iPhone stuck on Update Requested.
- If it gets stuck on Update Requested, just be patient.
- And once you've updated your iPhone,
check out our new video about the settings
you need to turn off.
It's appearing on the screen right now.
- Click It
Click it good.
Click it now.
