A volume backup stores all files and folders of the selected volume independent of their
attributes (including hidden and system files), the boot record, the file allocation table (FAT) if it
exists, the root and the zero track of the hard disk with the master boot record (MBR).
A disk backup stores all volumes of the selected disk (including hidden volumes such as the
vendor's maintenance partitions) and the zero track with the master boot record.
The following items are not included in a disk or volume backup (as well as in a file-level backup):

The swap file (pagefile.sys) and the file that keeps the RAM content when the machine goes
into hibernation (hiberfil.sys). After recovery, the files will be re-created in the appropriate
place with the zero size.

Windows shadow storage. The path to it is determined in the registry value VSS Default
Provider which can be found in the registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBa
ckup. This means that in operating systems starting with Windows Vista, Windows Restore
Points are not backed up.
Linux
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 About dynamic and logical volumes
3.7.1 Backup and recovery of dynamic volumes (Windows)
This section explains in brief how to back up and recover dynamic volumes (p. 437) using Acronis
Backup.
A dynamic volume is a volume located on dynamic disks (p. 436), or more exactly, on a disk group (p.
436). 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.
