A disk backup stores all disk volumes as well as the zero track with the master boot record.
Volumes with unsupported file systems will be backed up sector-by-sector.
Note on Linux machines
You can include both Windows and Linux volumes (partitions) in one centralized backup policy.
For instance, it is possible to set up a policy to back up volume C: on Windows machines and partition
/dev/hda1 on Linux machines.
/dev/hda1 on Linux machines.
Unlike Windows, there is no clear distinction between a volume (partition) and a folder (directory) in
Linux. Linux has the root partition (denoted as /), to which elements of various types—including hard
disks, directories, and system devices—are attached (mounted), forming a tree similar to the file and
folder structure in Windows.

For example, let a Linux machine contain a hard disk which is split into three volumes, or partitions:
the first, second, and third partitions. These partitions are available in the tree as /dev/hda1,
/dev/hda2, and /dev/hda3, respectively. To perform a disk backup of the, say, third partition, one can
type /dev/hda3 in the row of the Volumes to back up selection rules dialog box.

type /dev/hda3 in the row of the Volumes to back up selection rules dialog box.
Furthermore, a Linux partition can be mounted anywhere inside the tree. Say, /dev/hda3, can be
mounted as a “subdirectory” inside the tree, such as /home/usr/docs. In this case, one can type
either /dev/hda3 or /home/usr/docs in the Volume field to perform a disk backup of the third
partition.

partition.
In general, when setting up a centralized policy to perform volume backups of Linux machines, make
sure that the paths entered in the Volume field correspond to partitions (such as /dev/hda2 or
/home/usr/docs in the previous example), and not to directories.

Standard names for Linux partitions
Names such as /dev/hda1 reflect the standard way of naming IDE hard disk partitions in Linux. The
prefix hd signifies the disk type (IDE); a means that this is the first IDE hard disk on the system, and 1
denotes the first partition on the disk.
prefix hd signifies the disk type (IDE); a means that this is the first IDE hard disk on the system, and 1
denotes the first partition on the disk.
In general, the standard name for a Linux partition consists of three components:
•
Disk type; hd for IDE drives, sd for SCSI drives, md for software RAID drives (for example, dynamic
volumes);
volumes);
•
Disk number; a for the first disk, b for the second disk, etc.;
