User guide

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 from 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 Backup and recovery of dynamic volumes

(Windows)

This section explains in brief how to back up and recover dynamic volumes (p. 245) using Acronis

Backup & Recovery 11.5.

A dynamic volume is a volume located on dynamic disks (p. 244), or more exactly, on a disk group (p.

243). Acronis Backup & Recovery 11.5 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:
