A system administrator has backed up the datavg volume group using the savevg command. There are several raw logical volumes and some unmounted jfs filesystems in datavg. Which of the following statements is true about this backup?（）
A

The volume group and all logical volumes will be recreated. All raw and jfs filesystms will be backed up and restored.

B

This backup will be bootable and the volume group and all jfs logical volumes will be recreated.

C

This backup will not be bootable and the restorevg command is used to restore only the mounted and non-raw logical volumes. It will not recreate any logical volumes that are raw or unmounted.

D

The volume group and all logical volumes information is archived and will be recreated. The raw and unmounted filesystems will not be backed up and therefore not restored.
