Techniques and solutions are described for copying data from a source client to a target client. It may be selected, such as by a user, whether a full copy or a partial copy of a set of source client data should be made. If a partial copy is selected, a set of file types is provided. The file types can be used to define files that should be included in, or excluded from, the copy. A data source of the source client is analyzed to determine data associated with a file type that is to be included in a copy, or is associated with a file type that is not indicated as to be excluded from the copy. The determined data is copied from the source client to the target client.
