This section explains how to back up and restore L-Servers.
These functions are only provided for physical L-Servers.
Backup and restore of L-Servers is the function for performing backup and restoration of L-Server system images.
If multiple backups of the same L-Server are collected, the backups are managed by automatically adding version numbers to the backup file name starting from 1. If the number of snapshot versions exceeds the limit (standard limit is 3), the oldest snapshot will be deleted.
The content of the system disk of L-Server is restored to the state when the system image was collected.
Note
Not supported when using clustering software on physical L-Servers.
To back up and restore L-Server system images, the following conditions must be met:
