There are four job types FRP can perform.
1. Move - Simply moves data from the source folder to the destination. After the replication cycle is complete the source folder should be completely empty and the destination folder should contain any files that existed in the source folder. Any new item in the source folder will trigger a replication event. Nothing is removed from the destination folder. Files with the same name will be updated (not overwritten) in the destination folder on a bit level.
2. Copy - A simple copy of the source folder contents to the destination folder. New additions or changes to the source folder will trigger a replication event and will copy the data from the source folder to the destination folder. Deleting data from the source folder will not trigger any activity. Updating a file will trigger a replication event and will update (not overwrite) the destination file on a bit level. Renaming files or folders will be treated as if they are newly created folders or files. The destination end will keep the old file name and a new file will be created.
3. 1 Way Mirror - Mirrors the source files and folders to the destination folder. The destination folder will be identical to the source. Unlike the Move and Copy job types, the destination folder will have files (and folders) deleted or renamed if files (or folders) are deleted or renamed in the source folder. Files (and folders) that are altered on the destination side will be replaced or overwritten with the files from the source folder. Files and folders added to the destination server will be removed by 1 way mirror replication so as to maintain a correct mirror image.
4. 2 Way Mirror - Both replication servers will mirror each other. They both act as source and destination folders at the same time. The files with a newer time stamp will overwrite or update the files on the remote server. It is therefore critical to ensure the time settings on both servers are in sync with each other. This is normally done with an NTP program service, making both servers in sync with the same NTP server. Any change made to a file or folder that will incur a later time stamp than the remote mirrored server will trigger a replication to update the remote server. Unlike all other job types, changing data on either server will update the other server.
