Backup Performance - ACRONIS BACKUP AND RECOVERY 10 ADVANCED SERVER VIRTUAL EDITION - UPDATE 3 User Manual

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.
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.
HDD writing speed
This option is effective for Windows and Linux operating systems and bootable media.
This option is available when an internal (fixed) hard disk of the machine being backed up is selected
as the backup destination
Backing up to a fixed hard disk (for example, to Acronis Secure Zone) may slow performance of the
operating system and applications because of the large amounts of data that needs to be written to
the disk. You can limit the hard disk usage by the backup process to the desired level.
The preset is: Maximum.
To set the desired HDD writing speed for backup
Do any of the following:
 Click Writing speed stated as a percentage of the maximum speed of the destination hard disk,
and then drag the slider or select a percentage in the box

Click Writing speed stated in kilobytes per second, and then enter the writing speed in kilobytes
per second.
