User Guide

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. 134) and Recovering MD devices and logical volumes (p. 164),

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.

Physical drives that are part of hardware RAID arrays may be listed alongside other disks as if they

had a bad partition table or no partition table at all. Backing up such disks does not make sense as it

won’t be possible to recover them.

2.10. Tape support

Acronis Backup & Recovery 10 supports tape libraries, autoloaders, SCSI and USB tape drives as

storage devices. A tape device can be locally attached to a managed machine (in this case, the Acronis

Backup & Recovery 10 Agent writes and reads the tapes) or accessed through the Acronis Backup &

Recovery 10 Storage Node. Storage nodes ensure fully automatic operation of tape libraries and

autoloaders.

Backup archives created using different ways of access to tape have different formats. A tape written

by a storage node cannot be read by an agent.

Linux-based and PE-based bootable media allow for backup and recovery using both local access and

access through the storage node. Backups created using the bootable media can be recovered with

the Acronis Backup & Recovery 10 Agent running in the operating system.
