How to Change iMazing Backup Location on Mac and Windows
iMazing is one of the most capable iPhone and iPad management tools available, offering granular control over backups that Apple's own ecosystem simply doesn't provide. One of its most practical features is the ability to store backups wherever you choose — not just on your system drive. Whether you're running low on internal storage, organizing backups across multiple drives, or moving to a NAS setup, knowing how to redirect iMazing's backup path is genuinely useful.
Why iMazing Backup Location Matters
By default, iMazing stores device backups in a folder on your main system drive. On a Mac, this is typically within your user Library folder. On Windows, it's usually buried inside your AppData directory. Neither location is particularly accessible, and both consume space on your primary drive — which tends to be the most limited and most expensive storage in a modern setup.
Changing the backup location lets you:
- Offload large backups to an external SSD, HDD, or secondary internal drive
- Centralize backups on a network-attached storage (NAS) device
- Separate OS and data storage for cleaner system management
- Improve backup speeds if your external drive is faster than your internal one (common with older laptops)
How to Change the Backup Location in iMazing
The process is straightforward and doesn't require any command-line work or file system manipulation.
On Mac
- Open iMazing and connect your device, or simply launch the app without a device connected.
- Go to iMazing in the menu bar → Preferences.
- Click the Storage tab.
- Under Backup Location, you'll see the current folder path. Click Change or the folder icon next to it.
- Navigate to your preferred destination — an external drive, a folder on a secondary partition, or any accessible path.
- Confirm the selection. iMazing will ask whether you want to move existing backups to the new location or leave them in place.
On Windows
- Open iMazing and go to Edit in the top menu → Preferences.
- Select the Storage tab.
- Locate the Backup Location field and click Change.
- Browse to your target folder — this could be an external drive mapped as a drive letter, a secondary internal drive, or a synced network location.
- Choose whether to migrate existing backups or start fresh at the new path.
💡 If you choose to move existing backups during this step, iMazing handles the file transfer automatically. You don't need to manually copy anything.
Variables That Affect Your Setup
The "right" backup location isn't the same for every user. Several factors shape which destination actually makes sense.
Drive Type and Speed
Backup read and write speeds depend heavily on what you're writing to. A USB 3.0 or Thunderbolt SSD will handle large backups quickly and is a practical choice for most users. A USB 2.0 HDD will work but may feel sluggish with larger backups, particularly those containing extensive photo libraries or app data. Writing to a network drive introduces additional latency — acceptable for scheduled or overnight backups, but slower for on-demand use.
Available Storage Space
iMazing backups are not compressed in the same way iTunes/Finder backups are, and they retain historical versions by default. This is a powerful feature for recovering old app data or messages, but it means storage consumption can grow significantly over time. A device with 128GB of content could generate backups that exceed that capacity once multiple versions accumulate.
| Device Storage | Estimated Backup Size (Single) | With Versioning Enabled |
|---|---|---|
| 64GB device | 20–50GB depending on content | Can grow 2–5× over time |
| 128GB device | 40–100GB depending on content | Can grow significantly |
| 256GB device | 60–150GB+ depending on content | Plan for substantial room |
These are general ranges — actual sizes vary widely based on apps, media, and backup history settings.
Operating System and Permissions
On macOS, particularly Ventura and later, full disk access permissions affect whether iMazing can read and write to certain locations. If your chosen backup destination is on an external drive formatted as NTFS (common on drives used with Windows), macOS can read but not write to it natively without third-party drivers. APFS or exFAT are safer cross-platform choices.
On Windows, paths to network drives must remain consistently mapped. If a drive letter changes or a NAS becomes temporarily unavailable, iMazing may revert to its default path or throw an error on next backup.
Single vs. Multiple Devices 🗂️
If you're managing backups for multiple iPhones or iPads — family members, work devices, or test devices — all backups default to the same root folder. You can point them all to a single external drive, but it's worth understanding that iMazing organizes them by device within that folder structure, so you won't need to manually sort them.
The Spectrum of Use Cases
A user on a MacBook Air with a fast 1TB SSD and one personal iPhone has very different needs than someone managing five devices across a family on a Windows desktop with limited C: drive space and a large external HDD on USB 3.0. Both scenarios are well-served by changing the backup location — but the ideal destination, drive format, and version retention settings differ meaningfully between them.
Power users integrating iMazing into a home server or NAS workflow face additional considerations around drive availability, write permissions, and network consistency that casual users simply won't encounter.
What works cleanly in one setup may require adjustments in another — and that gap between general guidance and your specific configuration is where the real decision sits.
