WhatsApp Backup Filling Your Google Storage? How to Shrink It

The sequence is usually the same. Google emails you that your account storage is full, you clear a few hundred photos, and the figure barely moves. Then you open Google One and find a 12GB block attributed to nothing you recognise.

That block is very often your WhatsApp backup. Until 2024, Android WhatsApp backups sat on Google Drive without counting toward your free 15GB — a long standing arrangement between the two companies. That exemption was withdrawn, and the backup now competes with Gmail and Google Photos for the same pool.

Check the size first

This takes under a minute and tells you whether WhatsApp is actually your problem.

1. Open WhatsApp.
2. Tap the three-dot menu, then Settings.
3. Tap Chats, then Chat backup.
4. The screen shows Total size, the date of the last backup, and whether videos are included.

Cross-check against Google’s own figure at one.google.com/storage. Note that WhatsApp backups often do not appear as a separate line there, which is exactly why they are so hard to trace. If Gmail, Drive and Photos together fall well short of your reported total, the gap is hidden backup data — the general case is covered in what is actually using your Google 15GB.

What the backup actually contains

Understanding the composition tells you which lever to pull.

The message database — every text you have ever sent and received — is almost always under 500MB even on a decade-old account. Everything else is media. This is the same pattern as on-device storage, and it means one setting does most of the work.

Fix one: exclude videos

This is the highest-yield change available and takes two taps.

In Chat backup, turn off Include videos. The size estimate on the screen updates to reflect the change.

Then run Back up manually. The next backup replaces the old one rather than adding to it, so the space is reclaimed on that run rather than gradually.

The honest trade-off: videos remain on your phone and in your chats. What you lose is the ability to restore them to a new device. If your phone is stolen tomorrow, your messages and photos come back and your videos do not.

For most people that is an acceptable loss — the videos in question are usually forwards rather than originals. If a specific video genuinely matters, save it to your gallery or Google Photos separately, where it will be backed up properly and viewable without WhatsApp.

Fix two: clean the media before backing up

The backup is a snapshot of what is on the phone. Removing media first shrinks every subsequent backup permanently, and reclaims phone space at the same time.

Open Settings → Storage and data → Manage storage and work through the Larger than 5 MB and Forwarded many times filters. The full method, and the reassurance that it leaves your conversations untouched, is in cut WhatsApp storage without deleting chats.

Once that is done, return to Chat backup and tap Back up to write a new, smaller backup over the old one.

Doing the cleanup first and the video exclusion second is the right order. If you exclude videos but leave 8GB of photos in place, the backup is still large.

Fix three: use a separate Google account

If you want a complete backup including videos and do not want to pay for storage, a second Google account gives you another free 15GB.

In Chat backup, tap the Google Account entry and either select an existing account or add one. Future backups go there instead.

Two things to be aware of. First, the old backup on the original account is not moved or deleted — go to Drive on that account, open the menu, choose Backups, and remove it manually, or it keeps occupying the space you were trying to free. Second, you must remember which account holds the backup when you next set up a phone, because WhatsApp will not find it otherwise. Write it down somewhere that is not on the phone.

This is legitimate and supported, not a workaround that will break. It is simply slightly more to keep track of.

Fix four: reduce the backup frequency

In Chat backup, tap Back up to Google Drive and choose Only when I tap Back up instead of Daily.

This does not reduce the size of the backup — each backup replaces the previous one, so frequency has no effect on storage consumed. What it does is give you control over timing, which matters if you are on metered data or if daily backups are running at inconvenient moments. Treat it as a comfort setting rather than a storage fix.

What not to do

• Do not delete the backup to free space without understanding the cost. Your current chats live on the phone, so deleting the backup does not remove them. But you lose the restore point entirely. If the phone fails before the next backup, that history is gone — WhatsApp keeps no server-side copy.
• Do not turn off backup and assume WhatsApp holds your chats somewhere. It does not. End-to-end encryption means the messages exist on your device and nowhere else once delivered.
• Do not delete WhatsApp backup files from Drive’s file list by hand. They are not shown there as normal files, and the hidden entries that do appear can be confusing to identify. Use Backups in the Drive app menu, or WhatsApp’s own Delete backup control, so you know what you are removing.
• Do not pay for Google One before checking the video toggle. A 12GB backup frequently drops to 2GB from that one change, which is often enough to solve the problem for free.

The local backup, separately

Android also keeps a local backup on the phone itself, independent of Google Drive, in Android/media/com.whatsapp/WhatsApp/Databases. Files named msgstore-YYYY-MM-DD.1.db.crypt14 are older copies.

The most recent file is your local restore point. The older ones serve no purpose and can be several gigabytes in total. Deleting them frees phone space and has no effect on your Google quota, since they never left the device. Leave the newest one alone.

More on where these folders sit is in where WhatsApp photos and files are stored.

What to expect

A typical account with videos included runs an 8 to 15GB backup. Turning off Include videos alone usually brings that to 1.5 to 3GB. Adding a media cleanup before the next backup can take it below 1GB.

Google’s storage figure does not update instantly. After the new backup overwrites the old one, expect several hours and occasionally up to 72 before the number at one.google.com reflects reality. That delay is normal and not a sign the change failed.

If the backup is also failing or hanging rather than merely being large, that is a different symptom with different causes — see WhatsApp backup stuck on preparing.
