Backup and Recovery Information

In certain situations, it might be necessary to contact SonicWall for help as directed in SonicWall Support, or visit SonicWall, use SafeMode, or deregister the NSv virtual machine:

• If the splash screen remains displayed, this can indicate that the disk is corrupted. Contact SonicWall Technical Support for assistance.
• If the disk is not recoverable, then the NSv virtual machine needs to be deregistered with MySonicWall. Contact technical support for more information.
• If SonicOS does not boot up, you can go into SafeMode and download the log files, upload a new SonicOS image, or take other actions. For more information about SafeMode, see Using SafeMode on the NSv.
• If SonicOS fails three times during the boot process, it boots into SafeMode. Verify that the minimum required memory is available and allocated based on the NSv model. If it still cannot boot up, download the logs while in SafeMode and contact SonicWall Technical Support for assistance.

Moving configuration settings from SonicWall physical appliances to the NSv is not supported. However, configuration settings can be moved from one NSv to another. Contact SonicWall Technical Support for assistance.
