can configure a file to have both main and backup attribute, but only one file of either main or backup attribute is allowed on a device.

The following three situations are concerned with the main/backup attributes:

When saving the current configuration, you can specify the file to be a main or backup or normal configuration file.

When removing a configuration file from a device, you can specify to remove the main or backup configuration file. Or, if it is a file having both main and backup attribute, you can specify to erase the main or backup attribute of the file.

When setting the configuration file for next startup, you can specify to use the main or backup configuration file.

Startup with the configuration file

When booting, the system chooses the configuration files following the rules below:

1)If the main configuration file exists, the device initializes with this configuration.

2)If the main configuration file does not exist but the backup configuration file exists, the device initializes with the backup configuration.

3)If neither the main nor the backup configuration file exists, the device starts up without loading the configuration file.

Modes in saving the configuration

zFast saving mode. This is the mode when you use the save command without the safely keyword. The mode saves the file quicker but is likely to lose the original configuration file if the device reboots or the power fails during the process.
