Explanation

When data exists after work but disappears after a reboot, the most common cause is that the filesystem holding that data was mounted at /opt/data/user1 but the mount was not persisted in /etc/fstab. After reboot, the mount does not re-apply and the directory appears empty (showing the underlying empty mount point). The administrator should remount the drive and add the appropriate entry to /etc/fstab to make it persistent across reboots. Permissions issues, wrong folders, or deleted data would not cause data to appear only after a session and vanish on reboot.
