4.14.5 Overwrite file options
Choose what to do if the program finds a file in the target folder with the same name as in the
backup.
Selecting the Overwrite existing files check box will give the files from the backup unconditional
priority over the files on the hard disk, though, by default, the more recent files and folders are
protected against overwriting. If you want to overwrite those files and folders too, clear the
appropriate check box.
If you do not need to overwrite some files:
Select/clear the Hidden files and folders check box to enable/disable overwriting of all hidden
files and folders.
Select/clear the System files and folders check box to enable/disable overwriting of all system
files and folders.
Select/clear the More recent files and folders check box to enable/disable overwriting of new
files and folders.
Click Add specific files and folders to manage the list of custom files and folders that you do not
want to overwrite.
To disable overwriting of specific files, click the Add... button to create an exclusion criterion.
While specifying the criteria, you can use the common Windows wildcard characters. For
example, to preserve all files with extension .exe, you can add *.exe. Adding My???.exe will
preserve all .exe files with names consisting of five symbols and starting with “my”.
To delete a criterion, for example, added by mistake, click the Delete icon to the right of the
criterion.
4.14.6 Performance of recovery operation
On the Performance tab you can configure the following settings:
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
