Basically.
The reason it's not currently implemented in-game is because in it's current state, copying the files while they are being used by the client has a high chance of corrupting them.
(Windows issue. This doesn't happen on Linux.)Really think about it. You have a single region file that may be 1GB in size. Your average computer system is only capable of writing data at 75MB/s. If you have a newer system with SSD's you're looking at 250MB/s as an average. So it will take at best, 4 seconds to move a file which is constantly being written to several times a second.
That's just one region. After some gameplay you will have 20 or 30 of these files, plus the World data which is about 1GB by itself.
That's not even taking into account that multiple saves of this data is going to eat your HDD space alive. When one save is 12GB in size, and you want 10 backups or stages, that's 120GB of data.
