How to Reduce Android Backup Storage in Google Drive (4-Step Guide)
On one Android phone, apps, texts, call history, and settings combined added up to less than 132MB, while photos and videos on the same device totaled 76GB (Android Police, 15 months ago). That's a striking example, not a universal rule, but it points toward the real question behind how to reduce Android backup storage in Google Drive: check what's actually filling the account before touching a single setting.
Google Photos gets cited repeatedly as the reason free Google accounts hit the standard 15GB ceiling (Android Police, ~2 months ago). Once an account fills up, Android device backups stop running until space is freed (Android Police, 2.5 weeks ago), so a full account doesn't just block new photos. It quietly disables the safety net protecting everything else on the phone.
This guide covers checking what's actually consuming an account, stopping non-camera folders like WhatsApp and Screenshots from adding to the pile, reclaiming space already used, and learning to manage Android backup settings without losing anything worth keeping.
Step 1: check what counts toward Google storage before changing anything
Open Google Photos, tap the profile icon, choose Photos Settings, select Backup, and tap Manage Storage (How-To Geek, ~13 months ago). This screen breaks down which category, Photos and videos, Documents, or Other device data, is actually taking up the most room (Android Police, 2.5 weeks ago).
That number decides everything else in this guide:
- If WhatsApp, screenshots, or downloads make up a big share of "Photos and videos," folder auditing (Step 2) and cleanup (Step 3) are the fix.
- If the Camera folder itself is the majority of that number, backup quality (Step 4) is the more useful lever, and pruning side folders won't move it much.
- If Other device data is unusually large, which is uncommon, it deserves a look last.
Documents backed up this way can't be opened through Drive; they only restore back onto a device, and the footprint is normally small enough to ignore (Android Police, 2.5 weeks ago). The phone mentioned in the opening showed just how lopsided this split can get, but not every account looks that way, which is exactly why checking the actual breakdown beats assuming.
One change worth flagging while it's on the calendar: by the end of August 2026, all Android device backups will start counting against Google account quota. The extra load is expected to run between 30MB and 60MB, small enough that it isn't worth losing sleep over (Android Police, 2.5 weeks ago).
Step 2: stop non-camera folders from uploading to Google Photos
This setting lives in two places, depending on how it's reached.
Inside the Google Photos app: tap the profile icon, choose Photos settings, select Backup, then Back up device folders (Android Police, 2.5 weeks ago).
Inside Android's Settings app: go to Settings, then Google (or tap the profile icon at the top of Settings on Pixel), then Manage backup, then Photos & videos (How-To Geek, ~2.5 months ago). On Samsung-style interfaces, the equivalent route runs through Settings, then Accounts and backup, then Google backup (Android Police, 2.5 weeks ago).
Either route lands on the same list of folders. Most people have never opened this screen, which is exactly why it's worth a look first.
- Review the full list of folders currently uploading. There are usually more than expected.
- Leave Camera enabled. That's the one folder worth protecting at full quality.
- Disable WhatsApp folders if present. WhatsApp downloads a local copy of every image or video someone opens, and separately backs up chats and media to Google. If both processes capture the same local files, the same image or video can end up stored twice in the cloud (Android Police, 2.5 weeks ago). One heavy user found more than 1GB sitting in that local folder even after a monthly cleanup, and excluding it from Google Photos backup was estimated to save roughly 8GB to 12GB a year, a useful illustration of the ceiling rather than a guaranteed result for every account (Android Police, 2.5 weeks ago).
- Disable Screenshots. Most phones keep these in a dedicated folder, and toggling it off stops future uploads immediately (How-To Geek, ~13 months ago).
None of this deletes anything already sitting in the cloud. Turning off a folder only stops it from growing; whatever it already uploaded is still occupying space, which is what Step 3 handles.
Step 3: delete unnecessary Android backup data that's already uploaded
Disabling a folder is only half the job. If space is needed now, return to Manage Storage inside Google Photos to see exactly how much room each category, including screenshots, currently occupies (How-To Geek, ~13 months ago).
From there, searching "blurry" inside Google Photos surfaces likely junk such as blurry shots, screenshots, and oversized videos (How-To Geek, ~10 months ago). Confirm nothing worth keeping is in that pile, check local device copies or other backups first, then delete.
Deleted items don't disappear immediately. Google Photos holds them in Trash for 30 days by default, so freeing space right away means going to Collections, then Trash, tapping the three-dot menu, choosing Empty Trash, and confirming Delete Permanently (How-To Geek, ~13 months ago). That confirmation can't be undone, so it's worth a second look at the contents before committing.
Anyone who wants to keep a handful of screenshots or WhatsApp images can star them or move them into an album before deleting the rest (How-To Geek, ~13 months ago). That step helps identify what to keep during a bulk cleanup, but it does not protect an item that gets caught in a batch selection for deletion, so double-check the selection before confirming.
Step 4: when the camera roll itself is the problem: weighing backup quality
If the Camera folder is the real weight, folder auditing won't help much; backup quality is the setting to check instead. Reports differ on what the default even looks like: one account describes uploads defaulting to Original quality (Android Police, ~2 months ago), while another describes Storage Saver as the default doing the compressing (How-To Geek, ~10 months ago). Rather than assume either applies, open Backup quality directly and see what's actually selected on the device in question.
A single 50MB photo from a flagship camera adds up fast: 20 such shots can eat roughly 1GB of a 15GB free account (Android Police, ~2 months ago). Storage Saver compresses photos above 16MP and video above 1080p down to those caps, while Express compresses further, to 3MP photos and standard-definition video (Android Police, ~2 months ago). That compression typically shrinks photo file sizes by roughly 30% to more than 75% (How-To Geek, ~10 months ago).
Changing this setting only affects future uploads. Files already stored at Original quality aren't touched by the switch, and compression already applied through Storage Saver is permanent: once a photo or video has gone through it, that quality loss is baked into the file (How-To Geek, ~10 months ago).
To change it: open Google Photos, tap the profile icon, go to Photos settings, then Backup, then Backup quality. Choose Storage Saver to stay close to the original look, or Express if capacity matters more than fidelity.
This setting has to be applied separately on every device used to upload photos; it doesn't sync across phones (How-To Geek, ~10 months ago). Anyone editing photos professionally or relying on embedded EXIF data should stay on Original quality and manage capacity through other means, since that metadata only survives intact at full, uncompressed resolution (How-To Geek, ~10 months ago).
A smaller lever: trimming "other device data" (optional, last resort)
This category, covering SMS/MMS, call history, device settings, and app data, is rarely where meaningful space hides. One user disabled backup for a handful of apps and recovered about 200MB total, including one app that was backing up 30MB just to store payment details (Android Police, 2.5 weeks ago).
Some phones also show a separate toggle for backing up the Downloads folder, sitting just above Other device data on this same settings screen. It isn't available on every device, so check rather than assume it's there (How-To Geek, ~2.5 months ago).
Trimming Other device data is only worth bothering with after Photos and videos have already been handled, and only for the last few hundred megabytes. The path: Settings, then Google (or the profile icon on Pixel), then Manage backup, then Other device data, then toggle off Back up other device data.
That toggle deletes the existing cloud backup for that category, so a manual backup of anything important should happen first. Without it, restoring to a new phone won't bring back texts, app data, or settings (Android Police, 2.5 weeks ago).
Conclusion
Checking the storage breakdown before changing anything turns guesswork into a two-minute diagnosis: find which category is largest, then apply the fix built for that category rather than whichever setting is easiest to find.
The habit worth keeping is simpler than any single setting. Revisit "Back up device folders" whenever a new media-heavy app gets installed, since messaging apps, note-taking tools, and social apps that keep local copies of media are the most common source of fresh clutter. Catching them early is the surest way to save Google storage space on Android without ever having to run this full audit again.
