Most families think their photos are backed up because they are in iCloud or Google Photos. A cloud library is one copy, tied to one account and one payment card. Delete a photo on your phone and it disappears from the cloud too, and a locked or closed account can take years of pictures with it.
Back up family photos with the 3-2-1 rule: keep three copies on two kinds of storage, with one copy away from home. For most families that means the cloud library you already have, an external drive at home, and a second drive kept at a relative’s house or a second cloud service. Check each copy by opening a few files from it.
Why iCloud or Google Photos alone is not a backup
- Sync is not backup. With iCloud Photos on, deleting a photo on your iPhone deletes it everywhere. Google Photos backup works the same way once a photo is removed from your account.
- One account, one point of failure. A forgotten password, a lost phone that held your two-factor codes, or a lapsed storage plan can lock the whole library.
- Exports are not instant. If you ever need everything at once, Google Takeout and Apple’s copy request can take days. A drive you own is ready now.
Choose your three copies
| Copy | Good options | Notes |
|---|---|---|
| 1. Master | An external hard drive or SSD at least twice the size of your library | 2 TB or 4 TB suits most families. Label it. |
| 2. Second copy | A second drive, or your iCloud or Google Photos library | Two drives means no monthly fee. |
| 3. Away from home | A third drive kept at a relative’s home or at work, or a second cloud service | Swap the drive every few months. |
Hard drives cost less per terabyte; SSDs are faster and survive drops better. Either works for photos.
Make the first backup
- Gather everything into one master folder first. If your photos are only in the cloud, start with how to download all your photos from iCloud and Google Photos.
- Count the files and check the total against what each source showed.
- Copy the whole folder to the second drive, then make the third copy.
- Compare the item count and total size of each copy with the master. On Windows, right-click the folder and choose Properties; on a Mac, choose File › Get Info.
- Open 10 random photos and 2 videos from each copy, from different years. If any will not open, copy that folder again.
Keep it current
- Monthly, 15 minutes: copy the new month’s photos to the master, then to the other copies.
- Yearly: open a sample from every copy, swap the away-from-home drive, and replace any drive that is over 80% full or about five years old.
- Before deleting anything from a phone or cloud account, update all three copies.
A clean library is easier to back up. Once your copies exist, organize the photos into year and month folders and remove duplicates with the merge tool on iPhone or in Google Photos. Our free Cloud Storage Calculator helps you size a plan.
How big a drive to buy
| Library size | Drive size to buy | Why |
|---|---|---|
| Under 250 GB | 1 TB | Room for years of new photos and video |
| 250 GB to 1 TB | 2 TB | Twice the library, the usual rule |
| 1 TB to 2 TB | 4 TB | Video-heavy families land here |
| Over 2 TB | 8 TB or more | Consider a desktop drive with its own power supply |
Check your library size in iCloud or Google storage settings, or on your computer with Properties (Windows) or Get Info (Mac). Our free Video Storage Calculator estimates how fast video fills a drive.
Copy so nothing is skipped
- Copy the whole Photo Library folder in one go rather than year by year, so you cannot miss a folder.
- Leave the computer awake and plugged in. A sleep in the middle of a big copy is the most common cause of missing files.
- If Windows reports a file it cannot copy, note the name and copy that folder again afterward.
- Compare the item count and total size of the copy with the original before you call it done.
The away-from-home copy: drive or cloud
| Third drive at a relative’s | Cloud storage plan | |
|---|---|---|
| Monthly cost | None after buying the drive | A monthly or yearly fee |
| Stays current | Only when you swap it | Automatically, if set to sync |
| Protects against | Fire, theft, flood at home | Fire, theft, flood, and drive failure |
| Main risk | Forgetting to swap it | A lapsed payment or locked account |
Either works. If you choose cloud, use a different account or service from your main library, so one locked account cannot take both copies.
Questions
Is Google Photos or iCloud enough as one of the three copies? Yes, as long as you also have two copies you control. Treat it as the copy most at risk from a deleted photo syncing everywhere.
SSD or hard drive? Either. Hard drives cost less per terabyte for big libraries; SSDs are faster and handle drops better.
How often should I update the backups? Monthly is a good rhythm, plus right before you delete anything from a phone or cloud account.
What about RAID or a NAS? A network drive is convenient, but it counts as one copy in one place. You still need a copy away from home.
