Note on Linux machines

You can include both Windows and Linux volumes (partitions) in one centralized backup plan.

For example, it is possible to set up a centralized backup plan to back up volume C: on Windows

machines and partition /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). This forms 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, you can

specify the rule /dev/hda3 in the Data to Back Up dialog box.

Furthermore, a Linux partition can be mounted anywhere inside the tree. For example, /dev/hda3,

tree might be /home/usr/docs. In this

case, you can type either /dev/hda3 or /home/usr/docs in the Volume field to perform a disk backup

of the third partition.

In general, when setting up a centralized backup plan to perform volume backups of Linux machines,

make sure that the paths entered in the selection rules for volumes 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.

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)

 Disk number: a for the first disk, b for the second disk, and so on

 Partition number on the disk: 1 for the first partition, 2 for the second partition, and so on

To guarantee backing up selected disks regardless of their type, consider including three entries in

the Data to Back Up dialog box, one for each possible type. For example, to back up the first hard

disk of each Linux machine under a centralized backup plan, you may want to add the following rules:

/dev/hda1

/dev/sda1

/dev/mda1

Names for logical volumes

To back up logical volumes, also known as LVM volumes, specify their full names in the selection

rules. The full name of a logical volume includes the volume group to which the volume belongs.

For example, to back up two logical volumes, lv_root and lv_bin, both of which belong to the volume

group vg_mymachine, specify the following selection rules:

1 2 ... 290 291 292 293 294 295 296 297 298 299 300 ... 378 379
