A volume backup stores all files and directories of the selected volume independent of their
attributes, a boot record, and the file system super block.
A disk backup stores all disk volumes as well as the zero track with the master boot record.
With the sector-by-sector (raw mode) option enabled, a disk backup stores all the disk sectors. The
sector-by-sector backup can be used for backing up disks with unrecognized or unsupported file
systems and other proprietary data formats.
3.7 Backup and recovery of dynamic volumes
(Windows)
This section explains in brief how to back up and recover dynamic volumes (p. 238) using Acronis
Backup.
A dynamic volume is a volume located on dynamic disks (p. 237), or more exactly, on a disk group (p.
237). Acronis Backup supports the following dynamic volume types/RAID levels:

simple/spanned

striped (RAID 0)

mirrored (RAID 1)

a mirror of stripes (RAID 0+1)

RAID-5.
Backing up dynamic volumes
Dynamic volumes are backed up in the same way as basic volumes. When creating a backup plan
through the GUI, all types of volumes are available for selection as Items to back up. When using the
command line, specify the dynamic volumes with the DYN prefix.
Command line examples
acrocmd backup disk --volume=DYN1,DYN2 --loc=\\srv1\backups
--credentials=netuser1,pass1 --arc=dyn1_2_arc
This will back up volumes DYN1 and DYN2 to a network shared folder.
acrocmd backup disk --volume=DYN --loc=\\srv1\backups --credentials=netuser1,pass1
--arc=alldyn_arc
This will back up all dynamic volumes of the local machine to a network shared folder.
Recovering dynamic volumes
A dynamic volume can be recovered:

Over any type of existing volume.

To unallocated space of a disk group.

To unallocated space of a basic disk.

To a disk which has not been initialized.
Recovery over an existing volume
When a dynamic volume is recovered over an existing volume, either basic or dynamic, the
target volume’s data is overwritten with the backup content. The type of target volume (basic,
