your commands execution.
6.3.4 Compression level
The default setting – Normal.
If you select None, the data will be copied without any compression, which may significantly
increase the backup file size. However, if you select Maximum compression, the backup will
take longer to create.
The optimal data compression level depends on the type of files stored in the archive. For
example, even maximum compression will not significantly reduce the archive size if the
archive contains essentially compressed files, like .jpg, .pdf or .mp3.
Generally, it is recommended that you use the default Normal compression level. You might
want to select Maximum compression for removable media to reduce the number of blank
disks required.

6.3.5 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 physical characteristics of devices.
1. Backup process priority
The default setting – 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 of backup priority may 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 default setting – Maximum.
Backing up in the background to an internal hard disk (for example, to Acronis Secure Zone)
may slow other programs performance because of large amounts of data transferred to the
disk. You can limit the hard disk usage by Acronis True Image Workstation 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 default setting – Maximum.
