4.3.19 Performance of backup operation

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.

You cannot set or change the compression level for a pre-existing backup.

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
