Operating Systems: 

Last update: 27-09-2022

Acronis Cyber Protect Cloud and Acronis Cyber Protect 15 support backing up LDM volumes on all supported operating systems.

Consider the limitations described below when using Acronis Cyber Protect products on machines with LDM volumes such as Windows dynamic disks or Linux LVM.

For Agent-based backup via Agent for Windows/Linux or bootable media:

  • LDM volumes are backed up normally as volumes in Filesystem-aware mode
  • File filters are applied

For agentless VM backup via Agent for VMware/Hyper-V/Scale Computing/Virtuozzo/RHV:

  • If the backup software detects that disk is a part of a Dynamic volume/disk, it falls back to RAW disk backup: all sectors of the whole disk will be backed up without analyzing the partition structure on the disk and without storing the volume images separately
  • File filters are not applied for RAW disks
  How machine with LDM volumes is backed up
  Agent-based backup Agentless VM backup
Agent-based recovery Standard per-volume backup and recovery as for any physical machine

RAW backup of the VM.

Recovery of LDM volumes parsed from RAW backup is supported 

When recovering a Linux machine with bootable media, use Apply RAID/LVM to reproduce the original LVM structure (see p.12 on this page)

File/folder recovery of LDM and LVM volumes from disk backup is supported 

Agentless recovery

Run as VM operation is supported but could have bootability issues: check this article
