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 Tivoli® Storage Manager server
through the normal Tivoli Storage Manager client/server
protocol.
- The HTTPS protocol is not supported on the NetApp vFiler, therefore
the snapdiffhttps option does not apply to vFilers.
- The snapdiffhttps option is available only
by using the command-line interface. It is not available for use with
the backup-archive client GUI.
Options File
This
option is valid only on
the command-line interface. You cannot enter it in a client options
file.
