Troubleshooting Common Issues ​

Backup Problems ​

"Insufficient storage space" ​

  • Check available storage on backup volume
  • Change backup location to larger storage
  • Exclude cache from backup options
  • Clean old backups to free space

"Permission denied" errors ​

  • Verify root access in App Manager
  • Check backup location permissions
  • Try different backup directory
  • Restart App Manager and retry

"Backup verification failed" ​

  • Disable signature checks for problematic apps
  • Check storage integrity (run disk check)
  • Try different compression method
  • Update App Manager to latest version

Restore Problems ​

"App installation failed" ​

  • Some apps may need re-login

"Restore verification failed" ​

  • Enable skip signature checks temporarily
  • Check backup integrity with verification tool
  • Try restoring individual components separately
  • Re-create backup if consistently failing

Security Best Practices ​

Backup Security ​

Encryption Guidelines ​

  • Always encrypt sensitive app backups
  • Use strong, unique encryption keys
  • Store encryption keys separately from backups
  • Test backup restoration before relying on them

Access Control ​

  • Secure backup storage location
  • Use device screen lock (App Manager can leverage it)
  • Limit backup access to authorized users only
  • Regular security audits of backup procedures

Privacy Considerations ​

Sensitive Apps ​

  • Banking apps - May have additional security checks
  • 2FA apps - Backup carefully, may need re-setup
  • Password managers - Test restore thoroughly
  • Encrypted messengers - May lose message history

Data Handling ​

  • Review backup contents before sharing or storing
  • Clean sensitive data from test restores
  • Secure deletion of old or unwanted backups
  • Regular backup rotation for security

Automation & Scheduling ​

Profile-Based Automation ​

Creating Backup Profiles ​

  1. Open Profiles page in App Manager

  3. Add apps to profile in Apps tab
  4. Configure Backup/Restore in Configurations tab:
    • Set backup options
    • Enable backup state
    • Optionally set custom backup name
  5. Save profile for reuse

Profile Execution ​

  • Manual execution from Profiles page
  • Home screen shortcuts for quick access
  • Automation apps integration (Tasker, Automate)

Third-Party Automation ​

Tasker Integration ​

  1. Enable Authorization Manager in App Manager settings
  2. Create authorization key for Tasker
  3. Configure Tasker task with App Manager intent
  4. Set triggers (time, location, events)
  5. Test automation before relying on it

Performance Optimization ​

Backup Performance ​

Speed Improvements ​

  • Exclude cache directories from backups
  • Use fastest compression (Zstandard)
  • Backup to internal storage first, then move
  • Close other resource-intensive apps

Storage Efficiency ​

  • Regular cleanup of old backups
  • Monitor storage usage trends

System Impact ​

Resource Management ​

  • Schedule backups during low-usage periods
