How to backup photos: where to store them and why

Almost everyone who has lost photos lost them the same way. The photos existed in exactly one place, that place was a phone, and the phone was lost, stolen, dropped or simply stopped working one morning.

Knowing how to backup photos is not really a technical question. The mechanics take a few minutes. The part that decides whether it works is quieter: choosing somewhere the copy is genuinely separate from the original, making sure every folder is covered rather than just the camera roll, and keeping the files at full quality so they are still worth having in ten years.

This guide covers where to backup photos and why the choice matters, the difference between a backup and a sync, why originals beat compressed copies, and how to cover the pictures other people sent you, which is the category most people discover too late.

A phone is a single point of failure. Everything that lives only on it shares the phone's fate, and phones have a great many ways of coming to an end.

They get stolen from cafe tables. They go into washing machines, toilets and the sea. Screens stop responding. Batteries swell. An update occasionally bricks a handset outright, and repair shops cannot pull files off a device that will not power on.

None of that is dramatic or unlikely. It is the ordinary lifecycle of a device you carry everywhere and use several hundred times a day. The question is not whether a phone will eventually fail, it is whether anything irreplaceable disappears when it does.

The rule people in data recovery repeat is that a file exists only if it exists in two places. One copy is a file you currently have. Two copies, in two different places, is a file you can rely on having tomorrow.

This distinction is worth more than any other single thing on this page, because most people want a backup and have quietly been given a sync instead.

Sync keeps the same set of files on several devices. Change something in one place and the change appears everywhere. That is the point of it, and it is genuinely useful. It also means a deletion travels just as faithfully as an edit. Delete a folder on your laptop and a well behaved sync service removes it from your phone too, because that is exactly what you appeared to ask for.

Backup keeps a copy somewhere that is not affected by what happens to the original. Lose the phone and the copy is unaffected. Delete something locally and the copy is still there until you deliberately go and remove it.

The failure story is always the same. Someone tidied up their phone, or a family member did, and the pictures vanished from every device at once. Nothing malfunctioned. Sync did precisely what sync does.

Most people are best served by having both. Leave sync doing what it is good at, and keep a separate copy for the material you would actually be upset to lose.

There are four places people actually put photos. Each fails differently, and knowing which failure you are accepting is the whole decision.

An SD card or the phone itself

Cheap and immediate, and the option most likely to lose your pictures. Memory cards fail without warning and rarely give you any notice. More importantly, the card sits inside the same phone as the original, so a stolen or drowned handset takes both copies in one go. A card is extra room, not protection.

A computer or external drive

This genuinely works, and for years it was the standard answer. Two weaknesses. It depends on you remembering to do it, which in practice happens enthusiastically for a few months and then stops. And it puts everything on one drive in one building, so a failed drive, a fire or a burglary takes the lot.

As a second copy it is excellent. As the only copy it inherits every problem of the phone, just more slowly.

Printing or physical copies

Worth mentioning because it is the only option immune to technical failure entirely, and worth doing for a handful of pictures you truly care about. It is not a backup strategy for forty thousand images, but a printed photograph will outlive every format decision you are about to make.

Online cloud storage

This is the option that removes the remembering, which is why it ends up being the one that works. Once it is running, new pictures are copied without anyone deciding to do it, and the copy sits somewhere physically separate from the device.

That separation is what makes it a backup rather than a second pile of files in the same room. Cloud storage for photos also means the copy is reachable from a browser on any machine, which matters enormously on the day the phone is missing and you want to know what survived.

It is worth saying that online photo storage is not a single kind of product. Some services are built around sharing and social features, some around editing, and some simply around keeping a faithful copy. For a backup the last of those is what you want, so judge any photo cloud storage option on whether it returns your files unchanged rather than on the length of its feature list.

Some services offer a larger free allowance by storing a resized version of every image rather than the file you took. This is the decision people regret years later, and it cannot be undone.

On a phone screen you will never see the difference. A compressed copy looks perfectly good at the size you usually view it. The difference shows up in exactly three situations, and they are the situations that matter.

• Printing. Detail that was discarded at upload is not there to print. Enlargements suffer first and most visibly.
• Cropping. Zooming into a corner of a photo relies on resolution you may no longer have.
• Moving elsewhere later. If you ever migrate your library, you migrate whatever was kept. A compressed copy is permanently what you get back.

The decision is made once, silently, at the moment of upload. There is no later step where the original quality returns, because the data was thrown away to save room on someone else's servers.

So when judging the best way to store photos, capacity is the second question. The first is whether what you get back is what you put in. An allowance that sounds smaller but keeps originals is usually worth more than a larger one holding reduced copies of the same library.

The related question worth asking is whether you can get everything out again in bulk, in the original format. Being able to download your own library is what stops storage becoming somewhere photos go and do not come back from.

Most backup tools default to the camera folder. That covers what you photographed yourself and misses a surprising share of everything else, which people discover months later while hunting for something specific.

The folders worth checking deliberately, roughly in order of how often they are missed:

• Messaging media. Every picture friends and family sent you. These live in the messaging app's own folder and were never in your camera roll, so a camera only backup will never touch them.
• Screenshots. Tickets, confirmations, reference photos, the shot of where you parked. Their own folder, frequently excluded.
• Downloads. Images saved from a browser or pulled out of an email.
• Edited copies. Some gallery apps write edits to a separate folder rather than overwriting the original, so your edits and your originals can end up in different places.
• Social and third party camera apps. Some write to their own directory entirely.

Messaging media is the one that causes real distress. It is often where the pictures of family gatherings live, taken on somebody else's phone and sent to you, existing nowhere else in your possession. If you have ever lost a phone and later realised the group photos everyone sent are gone, this is why.

The mechanics are short. Most of the effort is in the first upload, which you do not have to be present for.

• Create an account and install the app, or open the web app in a browser if you would rather not install anything yet.
• Grant full access to your photos rather than selected or limited access. Limited access is a good privacy feature and the wrong answer for a backup, because the app can only ever see the pictures you individually picked.
• Go through the folder list and add messaging media, screenshots and downloads alongside your camera folder.
• Allow background activity so uploads continue when the screen is off, which is when you want them happening.
• Start the first run on Wi-Fi, plugged in, ideally overnight. It is uploading years of material at once, so hours is normal rather than a fault.
• Verify it finished by opening several pictures from your account in a browser on another device.

That last step is the one almost everyone skips and the one that decides whether the previous five did anything. Opening a photo on the phone proves nothing, because the phone has its own copy either way. Opening it on a laptop proves the copy in your account exists and is readable.

Platform specifics differ enough to matter. The Android guide covers permissions, folder coverage and the battery settings that stop uploads, and the iPhone guide covers the photo access choice and background refresh. The full setup walkthrough has all platforms in one place.

Once a backup is confirmed, the copies on the phone are duplicates. That is what makes it possible to store photos outside phone storage without losing anything, and it is why the order of operations matters so much.

Back up, verify by opening files from your account, then remove local copies. Never the other way round, and never while an upload is still in progress, because a file that has not finished uploading has nothing left behind it if you delete the original.

Some people keep everything local as well, simply because there is room. Others clear the phone regularly and treat it as a camera rather than an archive. Both are reasonable. What is not reasonable is deleting first and checking afterwards.

Sizing is easy to estimate. A phone photo is roughly 2MB to 5MB, so a gigabyte holds about 250 to 400 pictures and 100GB lands somewhere between 25,000 and 40,000. For most people who mainly shoot stills, that is years of headroom rather than months.

Monthly and yearly billing are both available. Full details sit on the features page, and the guide to what 100GB holds translates the numbers further. If your phone is already full, the guide to freeing up space covers the safe order for clearing it.

The instinct is to sort through everything first, delete the duplicates, tidy the albums, and then upload a clean library. This instinct delays backups by months and occasionally forever.

Curating forty thousand photos is genuinely tedious, so it gets started on a quiet Sunday, abandoned about six hundred images in, and never resumed. Meanwhile nothing is backed up, because the tidying was positioned as a prerequisite.

Upload everything first, including the blurry ones and the fifteen near identical frames of the same moment. Storage is cheap and your time is not. You can curate later from a position of safety, or never, which is what most people do and it costs them very little.

If your library is bigger than your allowance, upload in order of importance rather than waiting until you can do all of it at once. Camera roll first, then messaging media, then the rest. A partial backup that exists beats a complete one you never started.

The usual failure is not a backup that breaks loudly. It is one that stopped seven weeks ago while the app carried on looking entirely normal on your home screen.

Major system updates occasionally reset app permissions, battery restrictions drift back on for apps you have not opened recently, and a reset photo permission stops a backup instantly with no notification of any kind.

Two habits cover all of it:

• After any system update, open the app once. Ten seconds. If the status is up to date you are finished.
• Once a month, open your account in a browser and look for something recent. From a computer, not the phone. This is the only check that proves the copy is real.

That monthly glance is the entire maintenance requirement, and it is what separates a backup you can rely on from one you merely have.

The questions that come up most often about backing up photos and choosing somewhere to keep them.

• Pick somewhere genuinely separate from the phone, not a card inside it
• Check whether you are getting a backup or a sync, and ideally keep both
• Grant full photo access rather than selected access
• Add messaging media, screenshots and downloads to your folder selection
• Confirm originals are kept rather than compressed copies
• Run the first upload overnight on Wi-Fi and power
• Open several pictures from your account in a browser to verify
• Only then remove local copies, if you want the space back
• Glance at it once a month, and after every system update

If you take one thing from this page, make it the coverage check. Most incomplete backups are not broken, they are simply pointed at one folder out of five, and the pictures that matter most are frequently in the folders nobody selected.
