Google One is worth it just for photo backup if you use an Android phone or Google Photos as your main photo library and have already filled the free 15GB Google account storage, since it is the most direct way to keep backing up through the app you already use.
Who Google One suits
- Android and Google Photos users: Google One suits you if your phone already backs up through Google Photos, since upgrading storage there needs no new app or account, just a bigger storage plan on the account you already have.
- People who have already run out of free storage: Google One suits you if you are getting “storage full” warnings on Gmail, Google Photos or Google Drive, since all three share the same 15GB free allowance and a paid plan raises that shared limit.
- iPhone users: Google One is less of a natural fit if you are on an iPhone, since iCloud+ integrates more directly with Apple’s own Photos app, though Google One still works as a separate backup option if you want it.
What you actually get with Google One
- Shared storage: a Google One plan’s storage is shared across Gmail, Google Drive and Google Photos, not dedicated only to photos, so large amounts of email or files can eat into the space you meant for photos.
- Price tiers: Google One starts at a small monthly fee for 100GB, with larger tiers for 200GB, 2TB and beyond, generally cheaper per gigabyte than Apple’s equivalent iCloud+ tiers at the same size.
- Family sharing: most Google One plans let you share the storage plan with family members, so multiple people’s photos can draw from one pool rather than needing separate subscriptions.
- Cross-platform access: Google Photos and Google One work on both Android and iPhone, and through any web browser, so your backup is not locked to one device brand.
- What counts toward the limit: Google Photos backups saved at original quality count fully against your storage; older photos backed up at “storage saver” quality before mid-2021 do not count against the limit.
Questions to ask before you pay
- How much of your current 15GB free storage is actually photos, versus email attachments or files in Drive?
- Do you want to share the storage plan with family members, and does the tier you are considering support that?
- Are you also using Gmail or Google Drive heavily, which would share the same storage pool as your photos?
- Have you checked whether your existing photos are backed up at original quality or the older “storage saver” quality, since that affects how much space they use?
- Would a competing service, such as iCloud+ or a dedicated backup app, suit your devices better if you are not primarily on Android or Google Photos?
A low-cost way to decide
If you are getting storage warnings and already rely on Google Photos day to day, upgrading to the smallest Google One paid tier is a low-cost way to stop losing new backups while you decide on a longer-term plan. You can check exactly how much storage your photos, Gmail and Drive files are each using in your Google Account storage settings before choosing a tier.
Next step
Check your Google Account storage breakdown to see how much space photos, Gmail and Drive are each using, then compare that figure against Google One’s tiers to pick a plan with enough headroom for your photo backups to keep growing.
