how to configure the auto-save and auto-backup functions so that data is automatically saved in the flash memory or backed up to a FTP server. These functions ensure that data or configuration files are not lost after an emergency.
There are other methods to accomplish this, but this is the way I setup:
autosave time on
autosave time 23:00:00
autosave type all
file-server auto-backup configuration primary 192.168.150.100 ftp path olt/huawei-olt.config user
User Name(<=40 chars): 'type username'
User Password(<=40 chars): 'type password'
auto-backup period configuration interval 1 time 01:00
auto-backup period configuration enable
