III. Main/backup attribute of the configuration file
A main configuration file and a backup configuration file can exist simultaneously if the
device supports main/backup configuration file attribute. As such, when the main
configuration file is missing or damaged, the backup file can be used instead. This
increases the safety and reliability of the file system compared with the device that only
supports one configuration file. You can configure a file to have both the main and
backup attributes, 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 attribute:
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 the main and backup
attributes, you can specify to erase the main or backup attribute of the file.
When setting the configuration file for next startup, you can specify the
main/backup attribute of the file.
IV. Startup with the configuration file
The following steps are taken during system startup:
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 will:
Initialize with the default configuration file if it exists;
Or initialize with empty configuration if the default configuration file does not exist.

1.2.2 Saving the Current Configuration

You can modify the configuration on your device at the command line interface (CLI). To
use the modified configuration for your subsequent startups, you must save it (using the
save command) as a configuration file.
I. Modes in saving the configuration
Fast 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.
