Snapdiffhttps

Specify the snapdiffhttps option to use a secure HTTPS connection for communicating with a NetApp filer during a snapshot differential backup.

When you specify this option, the backup-archive client can establish a secure administrative session with the NetApp filer regardless of whether HTTP administrative access is enabled on the NetApp filer.

Important: The default communication protocol that the backup-archive client uses to establish the administrative session with the NetApp filer is HTTP. To use a secure HTTPS connection, you must specify the snapdiffhttps option whenever you run a snapshot differential backup.

Restrictions:

The following restrictions apply to snapshot differential backups with HTTPS:

The HTTPS connection is used only to securely transmit data over the administrative session between the backup-archive client and the NetApp filer. The administrative session data includes information such as filer credentials, snapshot information, and file names and attributes that are generated by the snapshot differencing process. The HTTPS connection is not used to transmit normal file data that is accessed on the filer by the client through file sharing. The HTTPS connection also does not apply to normal file data transmitted by the client to the IBM Spectrum Protect™ server through the normal IBM Spectrum Protect client/server protocol.
The snapdiffhttps option does not apply to vFilers because the HTTPS protocol is not supported on the NetApp vFiler.
The snapdiffhttps option is available only by using the command-line interface. It is not available for use with the backup-archive client GUI.

Supported Clients

Windows operating systems This option is valid for all Windows clients.

Linux operating systems This option is valid for Linux x86_64 clients.

Options File

This option is valid only on the command-line interface. You cannot enter it in a client options file.
