Parameters
filename: Specifies the name of a local backup file. For information about the filename argument, see
Fundamentals Configuration Guide.
url url: Specifies the URL of a remote backup file. Do not include a username or password in the URL.
username username: Specifies the username for logging in to the remote device.
cipher: Sets a ciphertext password.
simple: Sets a plaintext password.
key: Specifies the key string. This argument is case sensitive. If simple is specified, it must be a string of
1 to 32 characters. If cipher is specified, it must be a string of 1 to 73 characters.
Usage guidelines
For security purposes, all passwords, including passwords configured in plaintext, are saved in
ciphertext.
The command automatically creates the file if you specify a non-existent file.
With this command executed, the DHCP server backs up its bindings immediately and runs auto backup.
The server, by default, waits 300 seconds after a binding change to update the backup file. You can use
the dhcp server database update interval command to change the waiting time. If no DHCP binding
changes, the backup file is not updated.
