Ok I have run 2 back ups and they appeared to do correctly. I then went to my external hard drive just to check and see if they did. One did and one I get the message "The compressed(zipped) file is invalid or corrupted". What went wrong?
I'm not sure this is the right place to ask this question. I have been using FBackup for a year and have just noticed that the destination folders still contain files that have been deleted from the source folders - they're growing exponentially. I can't find out how to get the two folders to mirror each other.
