The preset is: Full cataloging.
If you select Full cataloging, the backup contents are cataloged to the highest possible level of detail.
This means that the following data will be displayed in the catalog:

For a disk-level backup - disks, volumes, files, and folders.

For a file-level backup - files and folders.
You may want to select Fast cataloging if the full cataloging tends to affect the performance of the
managed machine or if your backup window is too narrow. The following data will be displayed in the
catalog:

For a disk-level backup - only disks and volumes.

For a file-level backup - nothing.
To add the full contents of already existing backups to the catalog, you can start the full cataloging
manually when appropriate.
For more information about using the data catalog, see the "Data catalog" (p. 102) section.
4.7.4 Backup performance
Use this group of options to specify the amount of network and system resources to allocate to the
backup process.
Backup performance options might have a more or less noticeable effect on the speed of the backup
process. This depends on the overall system configuration and the physical characteristics of devices
the backup is being performed from or to.
4.7.4.1 Backup priority
This option is effective for both Windows and Linux operating systems.
The priority of a process running in a system determines the amount of CPU and system resources
allocated to that process. Decreasing the backup priority will free more resources for other
applications. Increasing the backup priority might speed up the backup process by requesting the
operating system to allocate more resources like the CPU to the backup application. However, the
resulting effect will depend on the overall CPU usage and other factors like disk in/out speed or
network traffic.
The preset is: Low.
To specify the backup process priority
Select one of the following:

Low – to minimize resources taken by the backup process, leaving more resources to other
processes running on the machine

Normal – to run the backup process with normal speed, allocating resources on a par with other
processes

High – to maximize the backup process speed by taking resources from other processes.
4.7.4.2 HDD writing speed
This option is effective for Windows and Linux operating systems and bootable media.
