5.3.5 Backup performance The three options below might have a more or less noticeable effect on the backup process speed. This depends on overall system configuration and the physical characteristics of the devices. 1. Backup priority The preset is Low. The priority of any process running in a system determines the amount of CPU usage and system resources allocated to that process. Decreasing the backup priority will free more resources for other CPU tasks. Increasing the backup priority might speed up the backup process due to taking resources from the other currently running processes. The effect will depend on total CPU usage and other factors. 2. HDD writing speed The preset is Maximum. Backing up in the background to an internal hard disk (for example, to BlackArmor Backup Secure Zone) may slow other programs' performance because of the large amounts of data transferred to the disk. You can limit the hard disk usage by Seagate BlackArmor Backup to a desired level. To set the desired HDD writing speed for data being backed up, drag the slider or enter the writing speed in kilobytes per second. 3. Network connection speed The preset is Maximum. If you frequently back up data to network drives, think of limiting the network bandwidth used by Seagate BlackArmor Backup. To set the desired data transfer speed, drag the slider or enter the bandwidth limit for transferring backup data in kilobytes per second. 38 Copyright (c) 2000-2009 Acronis. All rights reserved.

The three options below might have a more or less noticeable effect on the backup process
speed. This depends on overall system configuration and the physical characteristics of the
devices.
