1. Open Settings → Backup & Restore

    Use an account with the required administrative permission.

  2. Create Full Backup

    Wait for the backup to finish and appear in the backup list.

  3. Store important backups appropriately

    Keep at least one copy somewhere other than the same system disk when your operational policy requires it.

  4. Restore only with a reason

    Avoid testing a restore during a live school day. Use a planned maintenance window.

  5. Verify after restore

    Check schedules, calendar, audio, endpoints and settings before returning to normal operation.
