At the Processing step of the wizard, do the following:
- From the Cache repository drop-down list, select a cache repository where temporary cache files must be stored. This repository must be located as close to the source file share as possible.
- Use the Backup I/O control slider to define how fast the file proxy can read data from the source file share. This setting is based on the number of parallel threads that can be used by the proxy configured for processing the file share. If resources of your NAS device are limited, it is recommended that you select the Lower impact option. If your NAS device is powerful enough, select the Faster backup option.
- Click Next to save the configure settings.
