The Profile Set editor provides fine grained control for the restore of a Salesforce Profile record.
For a partial restore, specific sub-components of a Profile are selected for the restore. A partial restore is often used when migrating a Profile to a new environment where the original Profile contains entries related to objects/fields are not in the target Salesforce.
A complete restore will cause all properties of a Profile to be deployed.
An Expert restore provides fine control over the XML which is restored. See the Expert Mode Editor for details.
