The NAS OS rescue tool is preconfigured on your Seagate NAS. In addition to installing NAS OS, it can act as a bootable rescue tool to help you troubleshoot technical problems. The NAS OS rescue includes three recovery options:
The NAS OS rescue will attempt to repair or reset the NAS OS. To guarantee that data stored on the NAS is preserved, Seagate highly recommends that you back up all shares before moving forward with the Installer. If you cannot access the NAS volumes, the rescue provides an option to retrieve data via FTP.
Following the backup (if applicable), turn the NAS off. If you have access to NAS OS, use the power icon on the upper right of the window to select Shutdown. Otherwise, apply a short push to the power button.
The NAS OS rescue tool is enabled upon booting the NAS by simultaneously pushing the Recovery and power buttons. The recovery button is located on the back of the NAS within a small recessed niche. To push the recovery button, you will need a thin pointed object such as a paperclip or a small screwdriver.
Once it is enabled, the NAS OS rescue prompts you for the NAS's MAC address. Your NAS OS device has two MAC addresses, one for each LAN port (see the hardware user manual for your device). Check the MAC address label on the back of your device and note one of the MAC addresses.
