Karens Replicator is an easy-to-use backup tool for basic file replications. You can choose to backup an entire folder (optional with subfolders) and copy it to a different location. You have the options to only copy files that have changed and also keep an exact copy, thereby deleting all the files in the target folder that have been deleted in the source. The software comes with a built-in scheduler to automatically run backup jobs at specific times. You can create multiple backup jobs, however, each job is limited to the content of one folder (including optional subfolders). If all you need is to automatically backup the content of a few folders, than this tool is perfect for you.

Automatically backup files, directories, even entire drives! Karen's Replicator copies selected files from one drive/folder to another. Source and Destination folders can reside anywhere on your network.
Options include repeated copies at intervals as short as a few minutes, or as long as several months, copy only files that have changed, and the replication of folder and file deletions.
New features allow you to specify which files should not be copied, and also which days a file should be skipped!
