You have thousands of photos on your phone. Birthdays, vacations, the random Tuesday when your kid did something hilarious. If your phone broke or got stolen tomorrow, would those photos survive?
If the answer makes you nervous, this guide is for you. We're going to back up your phone photos to an external drive in about five minutes. No cloud subscription, no special hardware knowledge, and no ongoing fees beyond the app.
Why an external drive is the simplest option
There are lots of ways to back up photos: iCloud, Google Photos, a NAS, a home server. But for most people, an external drive is the right starting point because:
- You might already own one. Check your desk drawer. Many people have a USB drive sitting around unused.
- They're cheap. A brand new 2TB external drive costs $60–$80. That's enough for roughly 400,000 photos.
- No monthly fees. Unlike cloud storage, you buy it once and it's yours.
- It's completely private. Your photos never leave your home. No company can scan them, use them for AI training, or change the terms of service.
- It just works. Plug it in, set up the app, and forget about it. Photos back up automatically from that point on.
What you need
Two things:
- A computer (Mac or Windows). This is where you'll plug in the drive
- Any USB external drive, even an old one with some space left on it
That's it. Your computer acts as the bridge between your phone and the drive. Once set up, backups happen automatically over Wi-Fi whenever your phone is on the same network as your computer.
If you don't have an external drive yet, we have a recommended drives page with options at every price point. But honestly, any USB drive from any store will work.
Step-by-step setup
1. Plug in your external drive
Connect the drive to your computer and make sure it shows up. On a Mac, it'll appear in Finder. On Windows, it'll show up in File Explorer. If you see the drive, you're good.
If the drive is brand new and your computer asks to format it, go ahead and format it. The default settings are fine.
2. Install the Bombajom companion app on your computer
Download Bombajom Server from bombajom.com/download and install it. This small helper app runs quietly in the background and receives photos from your phone.
When it starts for the first time, it shows a "Choose Backup Folder" screen. Your external drive appears at the top of the list with its name and available space. Select it.

Bombajom Server then displays a QR code. Leave it on screen; you'll scan it with your phone in a minute.
3. Install Bombajom on your phone
Get Bombajom Photos from our download page. Open it and the first screen asks how you want to save your photos.
Choose "Scan a Setup QR Code". (There's also an "I Have a USB Drive" option that walks you through these same steps if you haven't set up the server yet.)

4. Connect to your computer
Point your phone's camera at the QR code on your computer screen. The app fills in the connection details automatically. Enter your password if asked, then tap "Connect".

If the connection fails, make sure both your phone and computer are on the same Wi-Fi network. That's the most common fix.
5. Start backing up
That's it for setup. The app will ask for permission to access your photos, and then your backup begins automatically.

Your first backup will take a little while: maybe 20 minutes for a few thousand photos, a couple of hours for a large library. After that, new photos back up within minutes of being taken.
You don't need to keep the app open. Background sync handles everything. Take a photo, put your phone in your pocket, and it'll be on your drive the next time your phone connects to your home Wi-Fi.
That's it. Five steps, five minutes of active effort, and your photos are protected.
Do I need to keep my computer on?
Your computer needs to be awake and the external drive needs to be plugged in for new photos to sync. But you don't need to worry about this much in practice:
- If your computer is a desktop that's always on, backups happen continuously.
- If it's a laptop, photos queue up on your phone and sync the next time your laptop is awake and on the network. Nothing is lost.
- Most people find that their laptop is open for a few hours each evening, which is plenty of time for the day's photos to sync.
If you want truly "always on" backup without leaving a computer running, that's where a NAS device comes in. But for most people, a computer that's on a few hours a day is more than enough.
Best drives to buy
Any USB external drive will work, but if you're shopping for one, here are our recommendations:
- Budget pick (under $50): A 1TB portable drive is plenty for most people and costs $40–$50. Brands like WD, Seagate, and Toshiba all make solid options.
- Sweet spot ($60–$80): A 2TB portable drive gives you room to grow. This is what we recommend for most families.
- Future-proof ($100–$130): A 4TB drive is overkill for photos alone but great if you also want to back up videos, documents, or use it for other things.
For specific models and where to buy them, check our recommended drives page.
One tip: get a portable drive (powered by USB, no wall plug) rather than a desktop drive. They're smaller, quieter, and easier to tuck behind your computer.
Frequently asked questions
What happens if the drive fails?
Hard drives can fail. It's rare with modern drives, but it happens. Here's how to protect yourself:
- Your photos are also still on your phone (unless you manually delete them). So even if the drive fails, you haven't lost everything.
- Consider a second copy. For about $60 more, a second external drive lets you keep another copy of your library. Copy your photos folder over every month or so. It's the gold standard for protecting irreplaceable files.
The short answer: a single drive is already much better than no backup at all. Two drives make it nearly bulletproof.
Can my family use it too?
Yes. Everyone in the family installs Bombajom on their phone, and each person's photos back up to their own folder on the same drive. Mom's photos go to a "Mom" folder, Dad's to a "Dad" folder, and so on.
Each person sets this up independently through the app. There's no complicated configuration on the computer side.
With a Bombajom Family plan, up to 12 computers can back up to the same drive.
Can I access my photos when I'm not at home?
The external drive setup is designed for home backup. When you're away from home, you can still browse any photos that are cached on your phone, but you won't see your full library until you're back on your home Wi-Fi.
If remote access matters to you, consider a NAS instead of an external drive. Most NAS devices (like Synology) offer built-in remote access, and Bombajom supports them out of the box. See our Synology setup guide for details.
How much space do I need?
A rough rule of thumb:
| Photos on your phone | Drive space needed |
|---|---|
| Under 5,000 | 32GB (any drive will do) |
| 5,000 – 20,000 | 100–200GB |
| 20,000 – 50,000 | 200GB – 1TB |
| 50,000+ or lots of video | 1TB – 2TB |
Most people are fine with a 1TB or 2TB drive, which covers years of growth.
What if I want to upgrade to a NAS later?
No problem. If you start with an external drive and later buy a NAS, Bombajom can migrate your library. Just set up the NAS as your new backup destination in the app, and it'll move everything over. You won't lose any photos or have to re-sync from your phone.
You're one step away from peace of mind
Right now your phone is the only place those photos exist. That's a single point of failure: one cracked screen, one stolen phone, one bad software update away from losing everything.
A $60 drive and five minutes of setup changes that. Your photos exist in two places, and the backup happens automatically from now on.
