Preparing disk groups and volumes

Before recovering dynamic volumes to bare metal you should create a disk group on the target

hardware.

You also might need to create or increase unallocated space on an existing disk group. This can be

done by deleting volumes or converting basic disks to dynamic.

You might want to change the target volume type (basic, simple/spanned, striped, mirrored, RAID

0+1, RAID 5). This can be done by deleting the target volume and creating a new volume on the

resulting unallocated space.

Acronis Backup & Recovery 11.5 includes a handy disk management utility which enables you to

perform the above operations both under the operating system and on bare metal. To find out more

about Acronis Disk Director Lite, see the Disk management (p. 180) section.

3.8 Support for UEFI-based machines

Acronis Backup & Recovery 11.5 can back up and recover machines that use Unified Extensible

Firmware Interface (UEFI) in the same way as it does for machines that use BIOS for booting.

This applies to both physical and virtual machines, no matter if the virtual machines are backed up at

a hypervisor level or from inside a guest OS.

For details about transferring Windows machines between UEFI and BIOS, see "Recovering BIOS-

based systems to UEFI-based or vice versa" (p. 116).

Limitations

 WinPE-based bootable media does not support UEFI booting. Use Linux-based bootable media

on machines with UEFI boot firmware.

 Acronis Active Restore (p. 237) is not available on UEFI machines.

 Acronis Startup Recovery Manager (ASRM) (p. 237) is not available on UEFI machines.

3.9 Compatibility with encryption software

Acronis Backup & Recovery 11.5 fully retains its functionality when interacting with file-level

encryption software.

Disk-level encryption software encrypts data on the fly. This is why data contained in the backup is

not encrypted. Disk-level encryption software often modifies system areas: boot records, or partition

tables, or file system tables. These factors affect disk-level backup and recovery, the ability of the

recovered system to boot and access to Acronis Secure Zone.

Under some conditions, Acronis Backup & Recovery 11.5 is compatible with the following disk-level

encryption software:

 Microsoft BitLocker Drive Encryption

 McAfee Endpoint Encryption

 PGP Whole Disk Encryption.

To ensure reliable disk-level recovery, follow the common rules and software-specific

recommendations.
