BackupCheck is a simple utility that checks that all files in specified folders are properly backed up. It does this as you would manually by comparing individual files. There are many clever and sophisticated backup software around but you don’t always master what they are doing.
With BackupCheck, it is trivial: all files in the specified folders are checked for an exact duplicate in matching backup folders. It might not be the most efficient way space-wise, but you have total control. BackupCheck displays a synthetic view of all files status, it is then up to you to copy files over or request BackupCheck to do it for you. You create no dependency on any software, not even BackupCheck itself as all backup files are plainly accessible via Finder.
