The server must be stopped in order to back up or restore its system volume, so a separate server is required for backup operations.
That is, at least two servers are required for this operation.
A configuration example for backup and restoration of a system volume is shown below.
Figure D.2 Configuration example for backup and restoration of a system volume
Note
The device names (i.e.: /dev/sda1) should be used to specify the root partitions of /etc/grub.conf and /etc/fstab of the server used for backup operations.
Normally, volume labels such as "/" or "/boot" are set for the system volume. The system volume for which the volume label is set is copied to the server used for backup operations by performing backup. Therefore, multiple partitions with the same volume label exist in the server used for backup operations. If the root partition of /etc/grub.conf and /etc/fstab is specified using the volume label name (i.e. LABEL=/ or /boot), the system may not operate correctly because the volume cannot be identified.
Point
If the backup source server and the server used for backup operations have different operating systems, refer to "9.1.1.11 Notes on executing copy between different operating systems" in "9.1.1 General notes".
