The photo backup you keep postponing

The warning comes up again while you are trying to take a picture: storage almost full. You delete a few long videos of the ceiling, the camera works again, and you put the phone back in your pocket.

Later that night it comes back to you. The photos from the first year of your daughter’s life are on that phone. Some of the ones before that are on the old laptop in the hall closet, the one that takes ten minutes to start. You are fairly sure some of them are in a cloud account, but you are not sure which ones, or whose account.

You have meant to back everything up since spring. It keeps getting pushed to a weekend with nothing else in it, and that weekend does not come.

The backup is not hard. It is unclear. Nobody has told you what “backed up” actually means, so the job has no edges, and a job with no edges never gets started.

One copy is no copy

Most family photos exist in exactly one place. On a phone that could be dropped in a lake, left in a taxi or replaced without a transfer. On a laptop with a drive that is now a decade old.

And a cloud service that syncs your photos is not always a backup. Many of them mirror what happens on your phone. Delete a photo on the phone, and after a short grace period it is often gone everywhere. Sync keeps your devices matching. A backup keeps a copy that a mistake cannot reach.

So the first step is a definition you can check.

Three copies, two kinds of storage, one away from home

The rule professionals use fits a household as well. Keep three copies of anything you cannot replace. Keep them on at least two different kinds of storage. Keep one of them somewhere other than your house.

For photos, that looks like this. The first copy is the library you already have, on your phone or computer. The second copy is a drive at home. The third copy is a second drive that lives somewhere else, like a desk drawer at work or a parent’s house, or a cloud service you understand well.

A fire, a burst pipe or a break-in can take everything in one house at once. The away copy is what is left.

One drive at home, one drive somewhere else

Here is the version that works without any special software.

The home drive gets updated once a month. It is small and fast, so the copy is over before you lose interest. It lives in a drawer near the computer.

The away drive gets updated every three months. On the first Sunday of January, April, July and October, it comes home for an evening, gets everything new, and goes back. A hard case protects it on the trip.

Before you buy, check how much space your photo library takes up now. Buy drives with at least double that, so there is room for the next few years.

Folders by year and month

Inside each drive, make one folder called Photos. Inside it, one folder for each year. Inside each year, one folder for each month, named so they sort themselves: 2026-09, 2026-10, 2026-11.

Do not sort by event, person or trip. Those systems need decisions, and decisions are what stall a backup. The date is the one system that maintains itself, because every photo already has one.

Each month’s backup adds one folder. You can see at a glance what is on each drive and where it stops.

The first backup is the long one

The first copy is years of photos at once, and it will take hours. That is normal, and it only happens once.

Start it in the evening. Plug the laptop into power, connect the drive, start the copy, and go to bed. Do not try to organize anything first. Copy everything, in whatever folders it is in now, into a folder called Before 2026. You can sort it later, or never. It is safe either way.

Then do the same for the old laptop in the closet, and any old phone in a drawer that still turns on. Every one of those is a single copy of something.

Put the first Sunday on the calendar

After the first backup, the monthly one takes about twenty minutes, most of it waiting.

Make it a repeating event on your calendar: first Sunday of the month, photo backup. Move the month’s photos from your phone to the computer if they are not there already, copy the new month folder to the home drive, and eject the drive before you unplug it.

Every third month, the reminder also says to bring the away drive home. Same steps, one more drive.

What to actually buy

You can start tonight with any external drive you already own. The system is three copies and a date on the calendar, not the hardware.

These are the pieces that make it a routine. Both drives come in larger sizes if your library needs more room.

The drive at home. A 1TB portable solid-state drive about the size of a credit card, fast enough that the monthly copy is done in a few minutes. It lives in the drawer by the computer.

The drive that lives somewhere else. A 2TB portable hard drive with room for the whole library and years to come. It stays at work or at a family member’s house and comes home four times a year.

The case for the trip. A hard-shell travel case for portable drives with a mesh pocket for the cable, so the away drive rides in a bag without getting knocked around.

The reader for camera cards. A USB-C card reader with SD and microSD slots for the photos on a camera, a drone or an old phone’s memory card. It plugs into newer laptops without an adapter.

When you miss a month

You will. A busy fall, a trip, a month when the first Sunday is a holiday.

The folders make catching up obvious. Open the home drive, look at the last month folder on it, and copy every month after that. Three missed months is one longer evening, not a failure.

The only real failure is stopping. If the routine has slipped for a year, start again with the first Sunday that comes up. The drives still hold everything they held.

Who this is not for

• If every photo you care about is already in a paid cloud service and you have checked how deletion and account recovery work on it, one drive at home may be all you need beside it.
• If you run a photography business, client work needs a professional setup with versioned backups and written agreements, not a monthly drive swap.
• If you share a photo library with a partner, agree on one person who owns backup day. A job that belongs to both people quietly belongs to nobody.

Start on any Monday

Tonight, find out how big your photo library is. On a phone, it is in the storage settings. On a computer, check the size of the folder where your photos live.

Write the number down. Then plug in any drive you own that has room, and start copying everything before you go to bed.

In the morning, put the first Sunday of next month on the calendar. That is the photo backup, and it is finally started.
