There's never too many photos on iPhone, right? Wrong. When it comes to backing up your iOS device, endless photos, messages, and files can suffocate your internal storage on Mac.
The first way to solve the problem is pretty straightforward: Keep your iPhone or iPad clean. It became a bit easier with the release of iOS 13, which allows removing similar shots and clutter from your Photos gallery automatically. If you take your gallery cleanness seriously, you can go further and install a smart duplicate finder like Gemini on your phone. Whether you're an Instagram husband/wife, or simply love good photography — this is a pro-level tool to save your disk space.

External Backup Storage For Mac
But what if photos are not the problem? Sometimes it's about text docs, mail attachments — lots of small files that become heavier and heavier as they pile up. It will take hours of work to free up storage space manually. So we suggest you don't. You can solve the problem by changing iPhone backup location instead.
In this guide, we'll tell you everything about where iPhone and iPad backups are stored by default, how to move them to an external drive, and what's the best Mac tool for running direct iOS backups.
How to change iPhone backup location on Mac
There are two Apple ways to backup iOS devices to Mac — using iTunes or iCloud. None of them is very easy. We've prepared detailed instructions on how to locate and move iPhone backup to an external drive both ways. If you follow these, nothing could go wrong.
Locate iOS backups in iTunes/Finder
Here's how you find a list of iOS backups if you use iTunes:
- Click on the Spotlight Search button in the menu bar
- Type the following command: ~/Library/Application Support/MobileSync/Backup/
- Hit Return.
The mechanism is a bit different if you're searching for a specific backup. In this case, go to iTunes > Preferences > Devices. Control-click the selected backup and select Show in Finder from the drop-down menu.
Note that if you're using macOS Catalina or later, you'll have to locate backups via Finder, while newer operating systems don’t have iTunes in its original form:
- Open a new Finder window
- Select Go > Go to Folder
- Type the command ~/Library/Application Support/MobileSync/Backup/
- Hit Go.
- Access your Backup folder from there.
An important thing to remember is that you shouldn't copy or extract specific files from your Backup folder — this might lead to your files being ruined. What you have to do is to copy and transfer an entire folder.
Locate iOS backups in iCloud
If you use iCloud for iPhone backups, you don't have to suffer from the low storage problem. Once your iPhone or iPad files are backed up, you can simply delete the backups. None of your valuable data will be damaged.
How to remove backups from iPhone or iPad and turn off backup for your device.
- Go to Settings > Your Name > iCloud
- Click Manage Storage > Backups for iOS 11 and iCloud Storage > Manage Storage for iOS 10.3
- Select your device name
- Delete Backup > Turn Off and Delete.
On your Mac:
- Apple menu > System Preferences > Apple ID > iCloud
- Select Manage and click on the Backups
- With the backup selected, click Delete to remove the backup. Confirm that you would also like to turn off Backup if needed.
Backup iPhone to external hard drive
For those who backup via iTunes/Finder, the journey isn't finished. Now it's time to backup iPhone to USB drive, an external hard drive that won't affect your storage on Mac. This should be done very carefully. Any attempt to extract files from the backup folder or using the wrong name of a hard drive may end up in a failure.
Also, let us warn you in advance that you shouldn't delete a backup after you move it to the new storage location. Before you do anything to your old iOS backups, make sure you set iTunes to backup from the hard drive. Let's go through it step by step.
How to save iPhone backup to external hard drive:
- Connect your external hard drive to Mac and open it.
- Select the backup folder from the Finder window or iTunes. Usually, the name of the backup folder consists of random numbers and letters, or it's called 'Backup.'
- Drag the entire folder — couldn't emphasize it more — to your external drive.
- Type your admin password.
- Rename the backup folder to 'iOS_backup' and enter the admin password once again to confirm your action.
Now, the most delicate part. It's not enough to create iPhone external storage, you have to tell iTunes where it is to ensure the backups will be done externally from now on. To make that work, you should create a new path — or a so-called symbolic link — for iTunes/Finder.
Before you dive into it, make sure you allow Full Disk Access for Terminal. You'll have to enable it manually if you use macOS Mojave. In this case, go to System Preferences > Security & Privacy > Privacy. Unlock by entering your admin password and click Full Disk Access. Add Terminal to the list of apps with full access permission via the plus button.
Now you're ready to work with Terminal. Make sure you pay close attention to every word you type — Terminal commands can be cumbersome. Open Terminal via Spotlight and type the following command (no rush, you might need to customize it):
ln-s/Volumes/External/ios_backup~/Library/ApplicationSupport/MobileSync/Backup/ 4f1234a05e6e7ccbaddfd12345678f1234b123f
In the command above, 'External' is the name of your hard drive. Possibly, your drive has a different name, so you'll have to change it in the command. The last part '4f1234a05e6e7ccbaddfd12345678f1234b123f' is the name of the backup folder. If you're transferring via Finder, it's very common for this folder to be named 'Backup.' Make sure they match or rename accordingly.
Once your command is accurate, hit Return and quit Terminal.
You've done everything right if you can find a newly created symlink file with the name of your backup folder in the MobileSync folder. The file icon should have an arrow in the bottom left corner.
Backing up to external drive: How to check it works?
Now when you've backed up iPhone to portable hard drive, run a test to see whether iTunes is really backing up from the new location:
- Connect your iPhone or iPad.
- Launch iTunes or find your device via Finder.
- Select Back Up Now.
- With the backup completed, open the iOS_backup folder on the external drive.
- Check the date and time of the last backup — it should coincide with your recent activity.
Only after the test proves successful can you delete your old backups.
How to backup iPhone directly to external drive
There are two big problems with iTunes backups. And we can understand why you say 'nay' to both of them. First of all, if you're backing up with iTunes or iCloud, you never know what files are covered. While you have to move an entire folder to your external drive, there's no way to check what's inside — not to mention selecting specific files for a backup.
Another thing is Terminal commands can go wrong — and they often do. A single mistake can break the whole process, so you'll have to start all over again. The good news is you can actually back up iPhone to external hard drive without iTunes and iCloud. The tool that you need for that is called AnyTrans for iOS.
AnyTrans is a Mac utility that handles connections across iOS, macOS, and Android devices. And by 'connections' we mean lots of useful things that built-in utilities like iTunes can't handle:
- Transfer media files, including photos, messages, and documents from your iPhone/iPad to Mac.
- Back up your iOS device to an external drive in seconds.
- Preview files that you're backing up and select your custom file types if you don't want to back up everything.
- Preview old iCloud and iTunes backups and transfer files from your old backup directly to an external drive.
As a nice perk, AnyTrans has a built-in media downloader that enables you to download video and audio from 900+ websites, including YouTube and Dailymotion.
The backup process is a four-step deal if you use AnyTrans — instead of complicated Terminal commands. Here's how you back up directly to external drive:
- Connect your iPhone or iPad to Mac and open AnyTrans.
- Click on Backup Manager and view the list of files that can be backed up.
- Tick the boxes next to specific file categories or select all.
- Choose your external drive as the target save location and click on the Next button to start backing up.
That's it. Everything you've backed up will now appear on your external drive. Also, check out information about what do you do if your iPhone wont turn on at all
Let's sum up with a few tips that will help you keep your iPhone data protected:
Double protection
If you're determined to use the built-in tools for your iOS and iPad backups, we recommend to use both iCloud and iTunes/Finder. It's never a waste of time when it comes to ensuring your data security. So in case something goes wrong, you'll have a backup plan. Pun intended.
Move backups across storages
Maybe you have lots of data. Or, you simply prefer cloud storage to storing your files on a local drive. That's understandable. To ensure nothing gets lost in the shuffle, use CloudMounter to mount your cloud drives as local disks and thus, transfer backups across multiple storages flexibly.
There's always a way back
We encourage you to simplify things with AnyTrans. And even if you decide to go with iTunes, note that you can always delete your symlink and try an easier option. To go back to internal backups, type ~/Library/Application Support/MobileSync/Backup in Spotlight and delete your symlink folder.
Two (or 162) for the price of one
Both AnyTrans and CloudMounter are available with a Setapp subscription. Setapp is a package of curated Mac utilities that solve the majority of jobs on Mac. So if you get the Setapp subscription, you'll be able to handle automatic iOS backups, move backups across storages and do 160+ other things.

Meantime, prepare for all the awesome things you can do with Setapp.

Need to backup one external hard drive to another in Windows
Sometimes we backup our important data or backup PC to external hard drive for better protection. While backing up external hard drive to another external hard drive seems necessary when one external hard drive has used as storage device.
For example, I store my photos on the newly bought 1 TB external hard drive, and I would like to backup this new drive to another external drive in case hard drive fails or computer meltdown one day. What’s more, a regular backup on external hard drive would be better for me because I wouldn’t expect myself to remember to backup manually every time.
Also I prefer incremental backup to backup only changed data to save my disk space. If I can encrypt my backup image I will feel even better (don’t call me greedy, you can’t be more careful with your data as well).
How to copy one external hard drive to another directly?
I tried to backup external hard drive to external hard drive on Windows 10 with its internal backup utility - Backup and Restore, only to find that:
1. It supports backup TO external hard drive not backup FROM the external hard drive. Yes, I can create system backup image to external hard drive or backup files to external drives with Windows tools, yet it is not my type.
2. Windows Backup and Restore software don’t allow you to create a system image to USB flash drive.
Lucky enough, I find one handy backup software that is free for my OS (I am running Windows 10) named AOMEI Backupper Standard. It also free for Windows 7/8/XP/Vista. This software has a user-friendly interface which is perfect designed for people like me who has less experiences of computer. And it enables you to copy Windows operating system to USB flash drive easily.
It is compatible with all brands of external hard drives, such as WD MyBook Duo, Buffalo MiniStation Extreme NFC, Toshiba Canvio Basics, LaCie Porsche Design, WD MyPassport, Adata SD700 External SSD, Samsung T5, WD Wireless Pro, etc.
Furthermore, this utility supports many useful features:
- Schedule backup, really saves my time and effort.
- System/disk/partition backup.
- Partition clone.
- File backup.
- Incremental and differential backup, etc.
In my situation, I stored mostly photos, documents, personal files, videos, and music on my external drive, so I would choose disk backup to get what I want.
Backup external drive to another external drive with free software
First of all, connect both external hard drives to my PC. Then download, install and open AOMEI Backupper standard.
Download Freeware
Win 10/8.1/8/7/XP
Secure Download
Now, I’ll show you the fastest way to transfer files between two external hard drives.
1. Select Disk Backup under Backup directory.
2. Select the 1 TB external hard drive as the source disk. Note that we can backup two or more external drives to a same place. Just select them all.
3. Click to select the other external hard drive as the destination hard drive.
4. Now it is time to set up regular backup and incremental backup. Check Schedule box to set planned backup time and incremental backup (I find the incremental backup is set by default after I open the window, it will backup the changed data since the last backup).
Click Options to encrypt my backup image. It is an advanced option so upgrading is needed.
5. Finally, click Start Backup, and it will backup one external hard drive to another without interrupting my work flow.
Download Backup To Mac From External Drive Mac
If you would like to manage storage space while backup disk full, please upgrade to AOMEI Backupper Professional or other editions to enjoy the Scheme option. It enables you to delete old backup images automatically while exceeding the backup number that you specified.
Other helpful features on external hard drive backup
I also find some features of this software that might be useful in the event of external drive duplication. List them one by one for reference.
- Sync. It is useful to sync files between two external hard drives when they are connected to one computer. Its advanced mode, real-time file sync, allows us to synchronize changed files in real time.
- Disk clone. I found backing up disk may be not the only way to transfer data between two drives. If you want to, a direct external hard drive to external hard drive clone is available. The biggest advantage of this method is that it saves the steps to restore a backup image.
- Bootable rescue media. This feature is not related to external hard drive backup directly, yet it provides an extra layer of protection for host operating system. Create a bootable device in advance and when system fails unexpectedly, we can use it to boot up computer and to, for example, backup hard drive without booting Windows.
There are other features such as check image and email notification that I cannot explain all, but this free software really a comprehensive tool that offers many practical options. Get it and explore by yourself.
Conclusion
It is not uncommon for us to backup external hard drive to another external hard drive. The question is to find one reliable and worry-free backup utility. What’s worth to mention, either the source external hard drive or the destination one, you need external drive backup software to back them up for double security.
AOMEI Backupper standard meets most of my computer and hard drive backup needs. I also restored Windows 10 backup to dissimilar hardware last week for my friend’s computer with the tutorial and the system works great till now. In my opinion, try it and maybe it will surprise you.
If you are Windows Server users, its AOMEI Backupper Server is suitable for you. This advanced edition allows you to merge backup images on external hard drive and manage storage space conveniently. You are able to do command line backup & restore as well.
