Policy rules for disks and volumes

When you select disks or volumes to back up, you can use the following policy rules, according to the operating system of the protected workload.

Windows

[All Volumes] selects all volumes on the machine.
Drive letter (for example, C:\) selects the volume with the specified drive letter.
[Fixed Volumes (physical machines)] selects all volumes of a physical machine, other than removable media. Fixed volumes include volumes on iSCSI, SCSI, ATAPI, ATA, SSA, SAS, and SATA devices, and on RAID arrays.
[BOOT+SYSTEM] selects the system and boot volumes. This is the minimal combination from which you can recover an operating system.
[Disk 1] selects the first disk of the machine, including all volumes on that disk. To select another disk, type the corresponding number.

Linux

[All Volumes] selects all mounted volumes on the machine.
/dev/hda1 selects the first volume on the first IDE hard disk.
/dev/sda1 selects the first volume on the first SCSI hard disk.
/dev/md1 selects the first software RAID hard disk.
To select other basic volumes, specify /dev/xdyN, where:
- "x" corresponds to the disk type
- "y" corresponds to the disk number (a for the first disk, b for the second disk, and so on)
- "N" is the volume number.
To select a logical volume, specify its path as it appears after running the ls /dev/mapper command under the root account.

For example:
```
[root@localhost ~]# ls /dev/mapper/
control vg_1-lv1 vg_1-lv2
```
This output shows two logical volumes, lv1 and lv2, that belong to the volume group vg_1. To back up these volumes, specify:

/dev/mapper/vg_1-lv1

/dev/mapper/vg-l-lv2

macOS

[All Volumes] selects all mounted volumes on the machine.
[Disk 1] Selects the first disk of the machine, including all volumes on that disk. To select another disk, specify the corresponding number.
