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 program comes with a built in time, that allows you to schedule it to run at user defined times. You can create multiple jobs, however, each job is limited to the content of one folder (subfolders), you cannot exclude/include individual files. If all you need is to automatically backup the content of a few folders, than this tool is perfect for you.

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!
