Eylul is a desktop backup and scheduling application developed by Spailor LLC. The app operates entirely on the user’s local computer and does not transmit or share any personal data. When the user chooses to back up files to Google Drive, Eylul uses only the drive.file permission scope — allowing secure upload of app-created backups to the user’s own Google Drive account through Google OAuth (SSO). All credentials and files remain private to the user.

Frequently Used Workflows

Run a Manual Backup

  1. From the Dashboard or Home, choose Back Up Now.
  2. Select a source (file/folder or SQL Server).
  3. Select a destination; optionally configure compression/encryption.
  4. Start the job → when finished, verify the result in LogsActivityView.

Create a New Schedule

  1. Open SchedulesView → New Schedule.
  2. On ScheduleEditPage, provide source/destination/scheduling info → Save.
  3. Verify the created schedule in SchedulesView.

Restore from a Backup

  1. From LogsActivityView (or the restore menu), select the backup.
  2. Choose a destination/target and conflict policy.
  3. Start restore → verify the result after completion.

Error Messages & Solutions

  • Disk full / write error: Ensure sufficient free space on the destination drive.
  • Permission error: Confirm the app has write permissions for the destination path.
  • OAuth / Google Drive authorization error: Re-authorize and verify OAuth credentials.
  • Email cannot be sent: Check mail provider credentials and network connectivity.

For detailed error codes and guidance, open the error details inside LogsActivityView.

Security & Important Notes

  • Store encryption keys securely; without them, encrypted backups cannot be recovered.
  • Do not keep production credentials and client secrets in public repositories or shared locations.
  • Restoring SQL Server databases can impact production systems; validate backups and restoration plans in a test environment first.
