Google confirmed in June that from July 2026 more of what an Android phone backs up will count toward the 15 GB free Google One quota. WhatsApp media, SMS attachments, and app data that used to sit outside the counter are moving inside it, so anyone with a full messaging archive or a large photo library will feel the pinch. If you have been coasting on the free tier, this is the moment to look around. We tested eight cloud backup apps for Android to find the ones that hold up when the plan you have been using is about to get smaller.
What to look for in a cloud backup app for Android
Backups are less exciting than photo apps until the phone dies. Then they are the only thing that matters. Four criteria decide whether a service is worth your setup time:
- How much free storage the app actually gives you today, not the promo tier from a launch three years ago.
- Whether encryption is end-to-end, so the provider cannot read your messages, contacts, or attachments even if compelled.
- Whether the Android app handles automatic photo uploads without eating the battery.
- How painful a full restore is when you move to a new phone.
We tested each of the eight against those four criteria and one bonus category: how well it plays with WhatsApp media, since that is the single largest bucket for most Android users.
Quick comparison
| App | Best for | Free plan | Starting price | Encryption |
|---|---|---|---|---|
| Google One | Staying inside the Google ecosystem | 15 GB | Around $2 for 100 GB | At rest, not end-to-end for backup |
| MEGA | Big free storage with real E2EE | 20 GB | Around $5 for 400 GB | End-to-end for everything |
| Sync.com | Zero-knowledge backups | Small free tier | Around $6 for 2 TB | End-to-end zero-knowledge |
| pCloud | Lifetime plans instead of monthly | 10 GB | Lifetime plans from $199 | Optional E2EE on paid tier |
| Proton Drive | Privacy-focused users | 5 GB | Around $5 for 200 GB | End-to-end for everything |
| Nextcloud | Full self-hosted control | Free with your own server | Managed hosting from ~$5 | Depends on setup |
| IDrive | Broad multi-device backup | 10 GB | Around $8 per year for 100 GB | E2EE optional per folder |
| Dropbox | Reliable syncing with third-party apps | 2 GB | Around $12 for 2 TB | At rest, not E2EE |
1. Google One — Best for staying in the Google ecosystem
Google One is the default on almost every non-Samsung Android and the app has grown into a real dashboard for what your phone is backing up. You can see the size of your device backup, restore any specific piece, and manage the storage shared across Photos, Drive, and Gmail. From July 2026 the quota rules tighten, so long-time free users will need to upgrade sooner or move some data elsewhere.
Where it falls short: Backups on Google One are encrypted at rest but the service can decrypt them in an emergency, which some users read as no real E2EE. WhatsApp backups are the exception, since Meta added end-to-end encryption on WhatsApp’s side.
Pricing:
- Free: 15 GB
- Paid: 100 GB tier around $2 per month, 200 GB around $3, 2 TB around $10 with family sharing
Platforms: Android, iOS, web
Download: Google Play
Bottom line: Google One is the right pick if you use Photos, Drive, and Gmail heavily and want one place to manage every backup.
2. MEGA — Best for a large free tier with end-to-end encryption
MEGA offers the largest free tier of any mainstream cloud storage in 2026, with 20 GB and periodic bonuses if you complete their achievement tasks. The Android app can auto-upload the camera roll, mirror a folder on the device, and back up chosen file paths on a schedule. Every file, folder, and share link is end-to-end encrypted, so MEGA cannot read your data even under legal pressure.
Where it falls short: MEGA’s transfer speeds throttle on the free tier once you hit a session cap. If you are uploading a large backup for the first time, plan around it.
Pricing:
- Free: 20 GB with periodic bonus quotas
- Paid: 400 GB around $5 per month, 2 TB around $11, 8 TB around $22
Platforms: Android, iOS, Windows, macOS, Linux, web
Download: Google Play
Bottom line: MEGA is the strongest free-tier option if you want E2EE without switching to a niche provider.
3. Sync.com — Best for zero-knowledge backups
Sync.com is a Canadian provider that has built its reputation on zero-knowledge encryption, meaning even Sync’s employees cannot decrypt your files. The Android app pairs with a very clean web dashboard. It handles photo backup, folder sync, and shared team spaces without the busy interface most rivals have grown.
Where it falls short: The free tier is small compared with MEGA and its file preview does not open every format, since decrypting for preview would break the zero-knowledge model.
Pricing:
- Free: 5 GB
- Paid: 2 TB around $6 per month, 4 TB around $10, larger business plans available
Platforms: Android, iOS, Windows, macOS, web
Download: Google Play
Bottom line: Sync.com is the pick for users who want serious privacy without touching Nextcloud.
4. pCloud — Best for lifetime plans instead of monthly
pCloud is the cloud service most likely to appear on the Android side of a Reddit thread about paying once and forgetting about it. The lifetime plans are the reason. If you back up a phone every three years and can put down a lump sum, the maths beats every monthly plan on this list. The Android app handles camera backup, a device sync folder, and remote uploads by link.
Where it falls short: Zero-knowledge encryption is a paid add-on (pCloud Crypto), so the base tier is not E2EE.
Pricing:
- Free: 10 GB
- Paid: 500 GB lifetime for around $199, 2 TB lifetime around $399, 10 TB lifetime around $1,190
Platforms: Android, iOS, Windows, macOS, Linux, web
Download: Google Play
Bottom line: pCloud is the calmest option if you want to buy backup once and stop worrying about a subscription.
5. Proton Drive — Best for privacy-focused users already on Proton
Proton Drive is the storage arm of Proton, the Swiss privacy suite behind Proton Mail and Proton VPN. It backs up your camera roll and a chosen folder on the device with end-to-end encryption by default. If you already pay for Proton Unlimited, the storage is included, which makes it the most cost-effective privacy option for existing Proton users.
Where it falls short: The Android app is younger than Sync’s or MEGA’s, so upload speed and background reliability still lag on cheap devices. Search is limited by design because filenames stay encrypted.
Pricing:
- Free: 5 GB
- Paid: Proton Drive Plus around $5 per month for 200 GB, Proton Unlimited around $10 with mail, VPN, and drive together
Platforms: Android, iOS, Windows, macOS, web
Download: Google Play
Bottom line: Proton Drive is the right pick if the Proton ecosystem already runs your email, VPN, and password manager.
6. Nextcloud — Best for full self-hosted control
Nextcloud is not a service. It is a piece of software you run on your own server or on a rented VPS, and the Android app connects to that server for backup and sync. There is a Nextcloud AIO container that installs everything at once, and a paid managed hosting market for people who want the app without running Linux. Once set up, it is the only option on this list where you truly own the backup medium.
Where it falls short: Setup takes real time. If your home internet goes down, your backup goes with it, and if you break the server, you also break the backup.
Pricing:
- Free: self-hosted, no license fee
- Paid: managed hosting from around $5 per month, business tiers for teams
Platforms: Android, iOS, Windows, macOS, Linux, web
Download: Google Play
Bottom line: Nextcloud is for anyone who wants their backup to answer to nobody but them.
7. IDrive — Best for broad multi-device backup
IDrive is the veteran on the list, aimed at users who want one account backing up phones, laptops, and desktops together. The Android app handles photos, videos, contacts, calendar, SMS, and call logs. IDrive keeps thirty versions of each file by default, so an accidental delete on the phone does not delete the backup right away.
Where it falls short: The Android app looks a little dated compared with Google One or MEGA. The UI has not had a major refresh in a while.
Pricing:
- Free: 10 GB
- Paid: 100 GB around $8 per year (unusually low), 500 GB around $30 per year, 5 TB around $80 per year
Platforms: Android, iOS, Windows, macOS, Linux, web
Download: Google Play
Bottom line: IDrive is the pick if you want one backup account across every device you own.
8. Dropbox — Best for reliable syncing with third-party apps
Dropbox is the oldest name on this list and it is still where a lot of third-party Android apps expect to save their exports. Camera upload works, folder sync works, and the integrations catalogue is enormous, but you pay for that maturity in a small free tier and a higher entry price.
Where it falls short: The 2 GB free tier is by far the smallest here, and there is no zero-knowledge option even on paid plans.
Pricing:
- Free: 2 GB
- Paid: 2 TB around $12 per month, family plans around $20
Platforms: Android, iOS, Windows, macOS, Linux, web
Download: Google Play
Bottom line: Dropbox is the pick if third-party app compatibility matters more than the raw price.
How to pick the right one
If you want the simplest option: Google One, at least for the parts of Android that only Google can back up cleanly. Pair it with something else for photos or WhatsApp if the free 15 GB is not enough.
If you need the biggest free tier: MEGA. Twenty gigabytes for free with real end-to-end encryption is the strongest combination on this list.
If you are on a budget across many years: pCloud with a lifetime plan. The break-even against a monthly plan lands around year three.
If you are a privacy user: Sync.com or Proton Drive. Sync gives more storage per dollar. Proton is the pick if you already pay for Proton Mail or VPN.
If you want to own the entire backup: Nextcloud. Nothing else on the list gives you the pipe end to end.
If you tried Dropbox and hated the paywall growth: IDrive. It is far cheaper per gigabyte and the Android app covers messages and call logs.
FAQ
What is the best free cloud backup app for Android?
MEGA is the best for free storage at 20 GB with end-to-end encryption. Google One’s 15 GB is the most convenient, since it comes preinstalled and knows about system settings. If you can pair the two, Google One handles the OS side and MEGA handles the photo roll.
Which cloud backup app is safest for Android?
Sync.com and Proton Drive are the closest to zero-knowledge providers, meaning even the company running the storage cannot read your data. MEGA is also end-to-end encrypted by default and has the largest free tier for that model.
Does Google One back up WhatsApp?
Yes, but from July 2026 WhatsApp media counts toward your 15 GB quota by default. The WhatsApp backup itself is end-to-end encrypted using a passphrase or hardware key, so Google cannot read the messages even if it stores them.
Can I use Nextcloud without running my own server?
Yes. Managed Nextcloud hosting starts around $5 per month with providers listed on the Nextcloud website. You get the same Android app experience without owning the hardware.
How do I migrate from Google One to another cloud backup?
Google Takeout can export your Drive, Photos, and other files as a downloadable archive. From there, upload to MEGA, pCloud, or your Nextcloud with the destination service’s Android app or web dashboard. WhatsApp backups need a separate step, since they are tied to Google’s WhatsApp integration and cannot be moved directly.
Is Samsung Cloud a real Google One alternative?
Samsung Cloud handles a narrow slice: contacts, calendar, and some Samsung apps’ data on Galaxy phones. It is not a general-purpose backup for photos or full app data, and the free storage is 15 GB shared across Samsung services. Treat it as a complement to Google One, not a replacement.
