Tape Support; Tape Compatibility Table - ACRONIS Backup & Recovery 10 Advanced Server User Manual

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. 228) and Recovering MD devices and logical volumes (p. 259),
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.

2.11 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 (p. 19). Storage nodes ensure fully automatic operation of tape
libraries and autoloaders (p. 133).
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.

The following table summarizes the readability of tapes written by Acronis True Image Echo and
Acronis True Image 9.1 product families in Acronis Backup & Recovery 10. The table also illustrates
the compatibility of tapes written by various components of Acronis Backup & Recovery 10.
