This read-write setting, when set to active, triggers the switch to upload its configuration or firmware to a TFTP server using the previously configured filename; reading it always returns notActive. Because a read never reflects the triggering action itself, an admin scripting a backup must set this to active and then separately verify success some other way, such as checking the TFTP server for the resulting file. For example, after configuring the desired backup filename, an admin would set this OID to active to kick off the actual backup transfer, then check the TFTP server's directory listing to confirm the file arrived.
