Telnet automatically places a check mark in the check box.

access. When disabled, remote users cannot access the director through

Backing Up and Restoring Configuration Data
You can back up the NV-RAM configuration, which includes all of the data you
input through instructions in this chapter, using the Backup and Restore
Configuration option. This option is available through the Maintenance menu.
Choosing this option backs up the configuration data to a file on the HAFM
appliance hard drive. The restore function writes this data back to NV-RAM on
the switch. Using the restore function overwrites the existing configuration. For
more information, see “
Backup and Restore Configuration ” on page 168.
In addition to the Backup and Restore Configuration option, the backup
application automatically backs up configuration and other critical data from the
HAFM appliance. As long as backup media remains in the backup drive of the
HAFM appliance, data is written to the backup media whenever the directory
contents change or you reboot the HAFM appliance. For more information, see
“
Backing Up and Restoring Element Manager Data ” on page 53.
Note: We do not recommend changing the default backup settings.
Caution: To ensure trouble-free backups, it is imperative that you leave the
backup media in the drive at all times. Removing the media during a backup
or restore can corrupt the database on the media.
When data is being written to or read from the backup drive, the CD-RW drive
write LED flashes. Make sure this LED is not flashing before you remove the
media.
