WhatsApp backup on Android never completes: causes and solutions

¿Does WhatsApp backup on Android never complete? If you've been looking at your phone screen for a while and you see that WhatsApp backups on Android never endYou're not the only one this happens to. The "Preparing backup..." message or the percentage stuck at 99% can drive anyone crazy, especially if you have important conversations you don't want to lose.

Often the fault is not obvious: it may stem from Google Drive, the connection, the Google account, the mobile phone's memory, or even the WhatsApp app itselfHere you'll find a very comprehensive guide, with all the common causes and the best-working solutions when backups get stuck on Android (and also what to do if the problem affects backups on iPhone or local backups).

Why is my WhatsApp backup on Android not completing?

When you see that the WhatsApp backup gets stuck on Android (sometimes at 0%, sometimes at 99%, sometimes eternally “preparing copy”), normally there are one or more combined factors that are blocking the process.

In most common cases, the origin lies in Google Drive or Google ServicesThe account is misconfigured, synchronization is broken, there are too many old backups, or the 15 GB of free storage is at its limit and there is no space left for more data.

It also has a big influence on Internet connection and network configurationIf the WiFi signal is weak, mobile data is limited, or WhatsApp only allows backups over WiFi, the backup may get stuck "thinking" without progressing or stop when you switch networks.

Another common cause is that WhatsApp or Google Play Services may be outdated, have a corrupted cache, or experience a temporary glitch.In those cases, the process starts but never ends, even if you have plenty of space and a good connection.

And finally, more serious problems should not be ruled out: software glitches in the mobile phone itself, errors in the Android backup system, or even hardware problemsand in some cases malware (follow the guide on How to detect and remove spyware from your Android phone)

Check Google Drive settings and available space

The first thing to check is whether your Google account and Google Drive are properly configuredBecause WhatsApp uses Drive to store backups on Android. If something goes wrong here, the backup either won't start or will freeze.

On your mobile device, go to Android Settings and check that You have at least one Google account added and activeWithout a correct account, neither the general device backup nor the WhatsApp backup can be uploaded to the cloud.

Next, it's time to look at the part of system:

1. Open the app Settings.
2. Scroll down to the section on System or system information (depending on the manufacturer's layer).
3. Enter Backup.
4. Check what email account It is associated with backups.

If your Drive account is the same one you use for WhatsApp, perfect; if not, Make sure WhatsApp is pointing to the correct account From WhatsApp Settings > Chats > Backup (see how to encrypt backups) > Google Account.

The next step is to check the storage on Drive. Often the backup gets stuck because There is not enough space left in Google Drive:

1. Open the app Google Drive on the mobile.
2. Open the side menu.
3. Look at the section where it says used and available space.

For automatic backups and WhatsApp backups to work properly, it's recommended to have at least 2 GB freeRemember that those 15 GB of free storage include files from Drive, Gmail emails, and all kinds of backups.

If it's almost full, you'll have to Delete files from Drive, empty emails with large attachments, or remove old backupsIf you use a lot of photos and videos, you might also consider subscribing to Google One to increase your storage space.

Clear cache and data from Google Drive and Google Services

Another typical reason why the backup gets stuck The problem is that the Google Drive app or Google Services may have corrupted cache or damaged data. Clearing this information often resolves many sync errors.

To empty the Google Drive cache On Android, you can follow these general steps (may vary slightly depending on the brand):

1. Go to Settings from the phone.
2. Enter Applications or Application Manager.
3. Search and open Google Drive.
4. Tap on Storage.
5. Click on Clear cache and, if the problem is serious, in Delete data.

This process does not delete your files from the cloud, it only deletes temporary files and local data which may be causing the failure. It is a safe and reversible action.

If it still fails, the next suspect is the Google Services (Sometimes they appear as Google Play Services or Carrier Services). A bad synchronization here can block both the general Android backup and the WhatsApp backup.

For force a “reset” of these services:

1. Open Settings > Applications.
2. Seeks Google Services o Carrier Services.
3. Enter Storage and cache and press on Clear cache y Delete storage/data.
4. Return to the app's main screen and tap on Forced arrest (as many times as necessary until the button turns gray).
5. Finally, Restart your phone.

After the restart, Google services regenerate on their own and, quite frequently, Backups are working normally again.

Check internet connection and network settings

It may seem silly, but a unstable or too slow connection This is one of the most common reasons why WhatsApp copying doesn't progress, especially if it includes photos and videos.

Start with the basics: Look for the WiFi or mobile data icon Check the status bar and see how many bars of signal you have. If you have weak signal, move closer to the router or go to an area with better coverage.

Next, do a short speed test (using any online test) to see if Do enough megabytes actually arrive on the mobile phone?If the download speed is very low or the ping is extremely high, it's normal for the backup to take forever.

You also need to check how you have WhatsApp configured to make copies:

1. Open WhatsApp.
2. Tap the three dots > Settings.
3. Enter Chats > Backup.
4. Look at the option of Save using mobile data.

If you only allow copying over WiFi and the wireless network is unstable, the copy will fail. It will cut out as soon as you lose the signal. or switch networks. If you have a data plan with enough data, you can activate the option to use mobile data to avoid these interruptions (keep in mind that a large backup can use up a lot of GB).

In some extreme cases it can help reset device network settings (In Settings > System > Reset options > Reset WiFi, mobile data, and Bluetooth). This erases WiFi passwords and APN settings, but also corrects unusual configurations that block connections.

Specific solutions for backing up WhatsApp on Android

In addition to all of the above, there are a number of specific steps within Android and the WhatsApp app itself that are extremely helpful when the WhatsApp backup doesn't finish or freezes.

1. Verify the Google account associated with WhatsApp

Sometimes the problem is as simple as this: WhatsApp is trying to back up an incorrect or inactive Google accountTo verify this:

1. Open WhatsApp.
2. Go to Settings > Chats > Backup.
3. Tap on Google Account and check which address appears.
4. If you suspect that account is not performing well, Change it to another one that you have on your mobile (or add a new Google account on Android and select it).

Many users have managed to get the copy to progress simply Trying with a different Google Drive accountYou don't have to lose the old copies: they remain associated with the other account in case you need them later.

2. Exclude videos and reduce the copy size

If you often send and receive a lot of videos (or don't want them to take up so much space), look alternatives for sending large files), it is very likely that the backup despite several gigabytesThe larger it is, the more likely it is to get stuck or take hours to finish.

WhatsApp allows disable the inclusion of videos in the backup:

1. Go to WhatsApp Settings > Chats > Backup.
2. Uncheck the option Include videos.
3. Start a manual backup again.

This way, only messages, photos, and other files are saved, which greatly reduces the size. If you see that this is the case... The copy is completedYou know that the bottleneck was the videos.

3. Force stop WhatsApp and clear cache

If the progress bar isn't moving, it may be that WhatsApp app has frozen in the background. In those cases, it's best to force it to close and clear its cache.

To do it from Android:

1. Go to Settings > Applications.
2. Search and open WhatsApp.
3. Click on Forced arrest.
4. Enter Storage and plays on Clear cache (Do not delete data if you don't know what you're doing, because that removes settings and can affect local files).
5. Restart your phone and reopen WhatsApp.
6. Try again. manual backup.

It's also a good idea to close WhatsApp from the app switcher (the recent apps view). by sliding the WhatsApp window up or off the screenbefore relaunching it.

4. Update WhatsApp and Google Play Services

Many backup issues are due to errors from older versions from WhatsApp or Google Play Services. Developers usually fix these bugs with updates.

Update everything that you can:

• Open Google Play Store.
• Seeks WhatsApp And if the Update button appears, tap it to get the latest stable version.
• Seeks Google Play Services and do the same if an update is available.

If you're signed up to WhatsApp Beta programPlease note that beta versions sometimes have more frequent bugs. If you're experiencing persistent copying issues, you can leave the beta program from the app's page on the Play Store and revert to the regular version.

5. Delete old WhatsApp backups from Google Drive

When many old WhatsApp backups accumulate in Google Drive, strange errors sometimes appear: Backups that never finish, restores that can't find backups, 99% crashes, etc.

For clean old copies from WhatsApp to Drive from a browser (mobile or computer):

1. Access drive.google.com with the Google account you use on WhatsApp.
2. Click on the gear icon (top right) and enter Configuration.
3. Go to the section Manage applications.
4. Seeks WhatsApp on the list.
5. In your options, select Delete application data or the equivalent option.

This will delete the backup WhatsApp has associated with that account in the cloud, but not your current chats on your phone. Then, on your phone, restart the app. a complete copy as if it were the first timeIn many cases, from that point on, the copies run smoothly again.

6. Try another Google Drive account

If none of the above has worked, it's worth trying with another completely different Google account to rule out that the problem is with your current Drive profile.

El procedure would:

1. Add a new google account in Settings > Device Accounts.
2. Go to WhatsApp > Settings > Chats > Backup.
3. Play on Google Account and select the new account.
4. To force a backup now.

If with that account The copy completes without problemsIt's most likely that your previous account had a lock or corruption issue in Drive. From that point on, you can continue using the new account for future backups.

Restart and “reset” the Android backup system

Sometimes, the fault lies within itself. Android automatic backupwhich gets stuck and also drags down the apps that depend on it, including WhatsApp.

One solution that often works is Deactivate and reactivate the mobile backup system.:

1. Open Settings.
2. Enter System.
3. Tap on Backup.
4. Turn off the backup option.
5. Wait a few minutes.
6. Go back to activate backup.

Normally, within a few minutes the phone general support resumes And with that, the situation with WhatsApp and Drive is often resolved.

If this measure is not enough, there is one more aggressive step to take: delete the backup of your own mobile phone in Google Drive and let a new one be generated from scratch.

1. Log in to Google Drive (app or web).
2. Open the menu and go to Backups.
3. Locate the copy of mobile that is causing problems (model and name of the device).
4. Tap the three dots and select Delete backup.
5. Then, from your mobile device, reinforce the previous process of turning the system backup off and on.

This forces Android to create a new backup from scratch, which often fixes the permanent hang-ups that prevent the process from moving forward.

What if the problem is with the iPhone or iCloud?

Although we focus on Android here, many users also experience this issue. WhatsApp backup stuck on iPhoneusually in the iCloud section. The reasons are similar: lack of space, network failures, corrupted old backups, or problems with Apple's servers.

On iOS, it is essential to first check that You have free space in iCloudIf you're running low on storage, iCloud will stop the process without much warning. You can see how much storage you have left by going to Settings > Your name > iCloud > Manage Storage.

It also helps to review the Apple status page (Apple System Status) to check if the iCloud servers are operational; if there is a global incident, there is little you can do beyond waiting.

Other typical solutions On iPhone they are:

• Reset network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings).
• Delete previous iCloud backups (Settings > Your name > iCloud > Backup > manage and delete some).
• Force restart iPhone (the classic “soft reset” by holding down the buttons according to the model).
• Update iOS to the latest stable version (Settings > General > Software update).

If the copy still doesn't work, many users opt for Create a full backup using iTunes or Finder on the computer, so that the WhatsApp conversations are safely backed up in a local copy.

Local WhatsApp backups, partial restores, and frequently asked questions

Before WhatsApp became so deeply integrated with Google Drive, the Backups were stored only locally (in the Databases folder of the internal storage) and, to change mobile phones, it was enough to copy that folder to the new device.

Today, although Drive has a more prominent role, Local copies still existWhatsApp usually saves a daily backup on your phone, and it's possible to restore from those backups if you keep them.

Several arise frequently asked questions:

• If I disable the backup to Drive and reinstall WhatsApp, can I still restore from local?
• Can I save multiple local copies (for example, from different months) and restore one or another as needed?

Generally speaking, if you configure WhatsApp so that the Set the copy frequency in Google Drive to “Never” And if you keep the database folder intact on the same device, reinstalling the app should offer you restore from local backup, provided that detect those files in their original location.

It is also possible to make "games" of manual copies: for example, Save a local copy from January to June on your PCand later, another from July to December. Each time you want to restore a specific one, you would have to:

1. Uninstall WhatsApp.
2. Copy the database file you want to use back to your mobile device, in the correct folder.
3. Install WhatsApp and verify the number.
4. Accept the restoration from local copy when the app detects it.

You have to do it carefully to avoid mixing files or accidentally overwriting them, but it's a valid way to preserve different “points in time” of your chats as long as the device and internal storage do not give errors.

If your mobile phone starts malfunctioning precisely in the local copies (errors when creating the daily backup, messages that are not saved, etc.)Then it is advisable to do more in-depth tests: uninstall and reinstall WhatsApp, check if any third-party app interferes, or even consider a factory reset of the device (after manually copying photos, videos and documents to the computer).

Alternative methods: professional tools for copies and transfers

When Google Drive or iCloud fail and there's no way to get a 100% backup, a practical solution is to resort to Specialized programs for WhatsApp backupsThese are desktop tools that allow you to make a complete copy on your computer without relying on the cloud.

2. Connect the Android or iPhone device via USB.
3. Choose the option of back up WhatsApp.
4. Wait for it to scan and copy all the app data.
5. Save the backup file to your PC.

The main advantage is that You are not dependent on Google Drive storage space or the status of its serversAnd you can also restore the backup to the same phone or a different one (even from Android to iPhone or vice versa, depending on the tool; see how). have WhatsApp on two phones).

Like everything, they have their fine print: they are paid apps or have limited features in the free version, and require a computerBut if you've been struggling with WhatsApp backups for weeks and nothing's working, they're a solid solution to keep your chats safe.

Extreme measures: disable security, perform a factory reset, or call a technician.

In some isolated cases, situations have been observed in which, when temporarily disable mobile phone security measures (fingerprint, PIN, pattern, facial recognition), the Google and WhatsApp backups were completed without problems.

It's not something comfortable or advisable to maintain over time, but as spot test The following can be done:

1. Go to Settings > Security.
2. Remove all screen lock methods (leave it on “None” or “Swipe”).
3. Try again backup.
4. If completed, reconfigure PIN, pattern, or fingerprint.

Beyond this, the last card that is usually left is the factory reset of the phoneBefore doing so, you must manually save all photos, videos, documents, and important files (via USB to PC, cloud, etc.), because the process erases all content from the device.

For restore the mobile phone:

1. Make sure it has sufficient battery or is plugged into the power supply.
2. Open Settings > System.
3. Enter Reset options.
4. Click on Erase all data (factory reset).
5. Confirm and wait for the process to finish.

When it turns back on, you will have to configure the mobile phone from scratchincluding the Google account and automatic backup restoration. If after this the general backups and the backup of WhatsApp They work, you'll know the problem was with the software.

If even after a full reset the device continues to fail to make backups (or shows other unusual symptoms), it is advisable to contact the manufacturer's official technical service.It could be an internal hardware failure or deep memory corruption requiring specialized intervention; in that scenario, it is key that the mobile phone has not been tampered with or mistreated so that the warranty can cover the repair.

When a WhatsApp backup on Android seems determined to never finish, the solution almost always involves a mix of stepsCheck Google Drive, free up space, clear caches, check your connection, adjust WhatsApp and system settings, or even use external tools to create a full backup on your computer; by following this process from least to most drastic, you'll most likely get the backup to complete again and keep your chats safe without losing important messages along the way.
