"Run as user" setting [Professional Only]
This setting can be found on the "Options" tab.
Selecting this option causes Synk to run the script as the user specified. When a user besides "root" is selected, it provides access to the files owned and accessible by that user without the potential for misdeeds that running as root can cause.
Note that this option only applies to local drives. Only logging onto a server as a user recognized by that server can give you this access on a remote machine.
