Performance of backup operation

On the Performance tab you can configure the following settings:

Compression level

You can choose the compression level for a backup:

• None - the data will be copied without any compression, which may significantly increase the backup file size.
• Normal - the recommended data compression level (set by default).
• High - higher backup file compression level, takes more time to create a backup.
• Maximum - maximum backup compression, but takes a long time to create a backup.

The optimal data compression level depends on the type of files stored in the backup. For example, even maximum compression will not significantly reduce the backup size, if the backup contains essentially compressed files, like .jpg, .pdf or .mp3.

Operation priority

Changing the priority of a backup or recovery process can make it run faster or slower (depending on whether you raise or lower the priority), but it can also adversely affect the performance of other running programs. The priority of any process running in a system, determines the amount of CPU usage and system resources allocated to that process. Decreasing the operation priority will free more resources for other CPU tasks. Increasing backup or recovery priority may speed up the process by taking resources from the other currently running processes. The effect will depend on total CPU usage and other factors.

You can set up the operation priority:

• Low (enabled by default) - the backup or recovery process will run slower, but the performance of other programs will be increased.
• Normal - the backup or recovery process will have the equal priority with other processes.
• High - the backup or recovery process will run faster, but the performance of other programs will be reduced. Be aware that selecting this option may result in 100% CPU usage by Acronis True Image 2014.

Network connection speed limit

When you back up data to Acronis Cloud, network drives, or FTP, you can reduce the influence of connection used by True Image on other network connections of your computer. Set the connection speed that will allow you to use Internet and network resources without annoying slowdowns.

To reduce connection speed:

• Select the Limit transfer rate to check box and specify an optimal value and an appropriate measurement unit (kilobits or megabits per second).
