The option '-a' implies that subfolders are included recursively. When the source will then differ from the target rsync will make an (incremental) backup. RAMDisk will then start a new copy (clone) of itself running in the background that will monitor the source issuing the unix command

Choosing one of them will bring up three consecutive dialog windows to choose the source and target file/folder and the respective backup interval. RAMDisk has a Tasks menu containing several commands, among them are the commands RAMDisk will backup open files and also offers the possibility to backup individual files.

A RAM disk has the advantage that reading and writing data are extremely fast.
