Backup image restoration

When installing the backup image, the system checks whether the target system has enough disk space to create all the logical volumes stored on the backup. If there is enough space, the entire backup is recovered. Otherwise, the installation halts and the system prompts you to choose more destination hard disks.

File systems created on the target system are the same size as they were on the source system, unless the SHRINK variable was set to yes in the image.data file before the backup image was made. An exception is the /tmp directory, which can be increased to allocate enough space for the bosboot command. For information about setting variables, see the image.data file.

When the system finishes installing the backup image, the installation program reconfigures the ODM on the target system. If the target system does not have exactly the same hardware configuration as the source system, the program might modify device attributes in the following target system files:

• All files in /etc/objrepos beginning with Cu
• All files in the /dev directory.
