By using the configuration backup and restore feature, you can easily back up and
restore the configurations in the whole fabric as well as in an individual unit.
In the backup process, the system first saves the current configuration of a unit to the
startup configuration file, and then uploads the file to the TFTP server. In the restore
process, the system downloads the startup configuration file from the server to the local
unit.
The configurations of different units in the fabric system can be saved in different .cfg
configuration files on the TFTP server. These configuration files correspond to different
unit IDs. The configuration of the whole fabric system is saved in one .cfg file, which
contains the current configurations of all the units in the fabric system.

z The relevant units support TFTP client.
