Compression level

This option is effective for Windows and Linux operating systems and bootable media.
The option defines the level of compression applied to the data being backed up.
The preset is: Normal.
The optimal data compression level depends on the type of data being backed up. For example, even
maximum compression will not significantly reduce the archive size if the archive contains essentially
compressed files, such as .jpg, .pdf or .mp3. However, formats such as .doc or .xls will be compressed
well.
To specify the compression level
Select one of the following:
•
None – the data will be copied as is, without any compression. The resulting backup size will be
maximal.
•
Normal – recommended in most cases.
•
High – the resulting backup size will typically be less than for the Normal level.
•
Maximum – the data will be compressed as much as possible. The backup duration will be
maximal. You may want to select maximum compression when backing up to removable media to
reduce the number of blank disks required.

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.
