The system has RAID-1 configured on two basic volumes: sdc1, sdd1.

You can back up the RAID array as follows:
trueimagecmd --create --partition:DYN1 --filename:/tmp/raid.tib --
progress:on
In the Graphical User Interface you can select the DYN1 check box.
Recovery
Parameters of software RAID arrays are not backed up, so they can only be recovered over a basic
volume, to unallocated space, or to a previously configured array. Recovery can be performed in
Linux or a Linux-based bootable media.
When started from bootable media, the bootable agent tries to access parameters of a software
disk array and configure it. However, if the necessary information is lost, the array cannot be
configured automatically. In this case, create a software array manually by using a command such
as mdadm, and then restart the recovery procedure.
For example, the following command creates an MD device /dev/md0 in the RAID-1 configuration
on the basic volumes /dev/sdc1 and /dev/sdd1:
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[cd]1
For detailed information about recovering software RAID arrays in Linux and bootable media, see
Recovering MD devices (Linux) (p. 244) and Recovering MD devices and logical volumes (p. 276),
respectively.
Hardware RAID arrays
Hardware RAID arrays under Linux combine several physical drives to create a single partitionable
disk. The special file related to a hardware RAID array is usually located in /dev/ataraid. You can back
up hardware RAID arrays in the same way as ordinary hard disks.
