Hey there! I'm sorry to hear that your backup is stuck at 99%. Let's try to get that issue resolved for you. Here’s a step-by-step guide we can follow to troubleshoot this situation:

### Step 1: Check Network Connection
Ensure that your internet connection is stable. Sometimes the backup process can stall if there’s a network disruption. You can try switching from Wi-Fi to mobile data or vice versa to see if that helps.

### Step 2: Restart the Backup Process
1. Pause and Resume: Try pausing the backup and then resuming it to see if that pushes it past the 99% mark.
2. Restart App: Close the Currys Cloud Backup app completely and then reopen it to restart the backup process.

### Step 3: Check for Large Files
If there are large files remaining, they might be causing the delay. Check your backup settings to exclude particularly large files temporarily to help the process complete.

### Step 4: Clear Cache (If Applicable)
Clear the cache of the Currys Cloud Backup app. This can sometimes resolve issues with stalled processes.

### Step 5: Verify Storage Space
Ensure you have enough storage space on your device and within your cloud storage plan for the backup to complete.

### Step 6: Update Software
Make sure that your mobile app and system are updated to the latest version to ensure compatibility and resolve any previous bugs.

### Step 7: Reboot Your Device
Sometimes, simply rebooting your phone can clear up lingering issues and allow the backup to complete.

### Step 8: Contact Support
If the issue persists after trying these steps, reaching out to Currys Cloud technical support would be the next best step. They can provide more in-depth assistance or check if there are any known server issues.
