CrossOver is a polished version of Wine provided by CodeWeavers.CrossOver makes it easier to use Wine and CodeWeavers provides excellent technical support to its users.If not, then best practice would actually be to back up the entire Mac with Time Machine so user preferences, applications, and system files can be easily restored (not just the folder of data) or Migrated during a reinstall if the hard drive died. A concern is if Time Machine is already configured on the Mac - you can't have two destinations.
