I use Super Duper and I think it will do what you need. I have been very pleased with it. You can get a FREE version to use. The free version does not have scheduled backup but the paid version ($27.95) has it all.

Create exact copies of files/folders from one external hard drive to another. 2. Do so on a scheduled basis, i.e., every night at 3 a.m. 3. Only copy or delete new or changed files when creating this one- way backup (as opposed to a full backup that recopies all files in the folder). I have been using LaCie's free Silverkeeper backup software to do this for several years, but for some reason it is no longer correctly detecting changed files on the source drive in a particular folder. Even though the file on the source drive has changed, Silverkeeper reports that it finds no difference between that file on the source drive and one of the same name on the destination drive, therefore no fresh copy is made and the backup is not accurate. I need either to figure out why Silverkeeper is not working right or find a new backup program that can do the same thing reliably. Note that I am _not_ looking for incremental or full backups, as Apple's Backup program does quite nicely. I'm looking for a "one-way mirror" backup utility. Every night at a designated time the contents of Folder A on Source Drive are mirrored on Destination Drive. If any files have been deleted in Folder A on Source Drive, they will get deleted in Folder A on Destination; if a file in Folder A on Source has been added or changed it will be added or changed on Destination. If a file on Source Drive has not changed and it already exists on Destination, it will not be touched. Any recommendations? _______________________________________________ The next Louisville Computer Society meeting will be October 23 at MacAuthority, 128 Breckinridge Lane.
