How to Configure the Auto-save Function for Huawei OLT

This topic describes how to configure the auto-save function so that the system configuration data or database files can be saved automatically. You can also make an reference for the MA5680T, MA5616, MA5608T, MA5603T, MA5600T.
Background Information
The MA5600 supports two auto-save modes:

• Auto-save at preset interval.
• Auto-save at preset time.

Pay attention to the following points:

• Auto-save at preset time conflicts with auto-save at preset interval. You can enable only one of them.
• Saving data frequently affects the system. Therefore, an auto-save interval shorter than one hour is not recommended, and it is recommended that you set the interval equal to or longer than one day.
• Before the system upgrade operation, run the autosave interval off or autosave time off command to disable the auto-save function to prevent upgrade failure due to the conflict between upgrade and auto-save operations.

 NOTICE:
After the system upgrade is completed, you must re-enable the auto-save function if the auto-save function is required.

Procedure

• Configure auto-save at preset interval.
  1. In the global config mode, run the autosave interval on command to enable auto-save at preset interval.

Auto-save at preset interval conflicts with auto-save at preset time. You can enable only one of them.

2. (Optional) In the global config mode, run the autosave interval configuration command to set the auto-save interval for modified system data.

Auto-save is performed according to the interval set by the user. The system checks whether the system data is modified at each interval. If the system data is modified, the system saves the data. Otherwise, the system does not save the data. By default, the interval is 30 minutes.

3. (Optional) In the global config mode, run the autosave interval command to set the auto-save interval.

After the setting, the system data is automatically saved at the set interval regardless of whether the system data is modified. By default, the interval is 24 hours.

4. (Optional) Set the auto-save file type.

In the global config mode, run the autosave type command to set the auto-save file type.

• Configure auto-save at preset time.
  1. In the global mode, run the autosave time on command to enable auto-save at preset time.

Auto-save at preset time conflicts with auto-save at preset interval. You can enable only one of them.

2. (Optional) In the global config mode, run the autosave time command to set the auto-save time.

After the setting, the system data is automatically saved at the set time regardless of whether the system data is modified. By default, the time is 00:00:00.

3. (Optional) Set the auto-save file type.

In the global config mode, run the autosave type command to set the auto-save file type.
Example
To enable auto-save at preset interval on the MA5600, set the auto-save interval to two days (2880 minutes), and save both the database file and the configuration file, do as follows:
huawei(config)#autosave interval on
huawei(config)#autosave interval 2880
huawei(config)#autosave type all
huawei(config)#save
