Beginner/Intermediate shell; comfortable in the command line.
I have been looking for a solution to a backup problem. I need to compare Directory 1 to Directory 2 and copy all modified or new files/directories from Directory 1 to Directory 3. I need the directory and file structure to be mirrored on Directory 3. Another way of thinking about the logic is: Dir1 - Dir2 = Dir3. I want Dir3 to be portable between users/machines so I don't think an incremental backup with hardlinks will work. Seems like it should be easy right?
I found a scripts that seems like it could do the trick. However, I'm having some trouble getting it to work properly. It compares Dir1 to Dir2 and copies all new or modified files into Dir3 but it does NOT recreate the directory structure on the target. Instead all files end up in a flat folder.

I started my reading with rsync. I've used it for back up - locally and over ssh between NAS servers. It should be able to do the job, right? I just couldn't find examples to guide me and I don't know enough and / or have enough time to do it unaided. Researching it I got side tracked by diff which I didn't know much about but it looked promising.
My preference is to do this with a bash script. Anyone have any ideas?

script - Boot script
DESCRIPTION
The boot script describes how the Erlang runtime system is started. It contains instructions on which code to load and which processes and
applications to start.
The command erl -boot Name starts the system with a boot file called Name.boot , which is generated from the Name.script file, using sys-
tools:script2boot/1 .
The .script file is generated by systools from a .rel file and .app files.
FILE SYNTAX
The boot script is stored in a file with the extension .script
The file has the following syntax:
{script, {Name, Vsn},
[
{progress, loading},
{preLoaded, [Mod1, Mod2, ...]},
{path, [Dir1,"$ROOT/Dir",...]}.
{primLoad, [Mod1, Mod2, ...]},
...
{kernel_load_completed},
{progress, loaded},
{kernelProcess, Name, {Mod, Func, Args}},
...
{apply, {Mod, Func, Args}},
...
{progress, started}]}.
* Name = string() defines the name of the system.
* Vsn = string() defines the version of the system.
* {progress, Term} sets the "progress" of the initialization program. The function init:get_status() returns the current value of the
progress, which is {InternalStatus,Term} .
* {path, [Dir]} where Dir is a string. This argument sets the load path of the system to [Dir] . The load path used to load modules is
obtained from the initial load path, which is given in the script file, together with any path flags which were supplied in the command
line arguments. The command line arguments modify the path as follows:
* -pa Dir1 Dir2 ... DirN adds the directories Dir1, Dir2, ..., DirN to the front of the initial load path.
* -pz Dir1 Dir2 ... DirN adds the directories Dir1, Dir2, ..., DirN to the end of the initial load path.
* -path Dir1 Dir2 ... DirN defines a set of directories Dir1, Dir2, ..., DirN which replaces the search path given in the script file.
Directory names in the path are interpreted as follows:
* Directory names starting with / are assumed to be absolute path names.
* Directory names not starting with / are assumed to be relative the current working directory.
* The special $ROOT variable can only be used in the script, not as a command line argument. The given directory is relative the
Erlang installation directory.
* {primLoad, [Mod]} loads the modules [Mod] from the directories specified in Path . The script interpreter fetches the appropriate mod-
ule by calling the function erl_prim_loader:get_file(Mod) . A fatal error which terminates the system will occur if the module cannot
be located.
* {kernel_load_completed} indicates that all modules which must be loaded before any processes are started are loaded. In interactive
mode, all {primLoad,[Mod]} commands interpreted after this command are ignored, and these modules are loaded on demand. In embedded
mode, kernel_load_completed is ignored, and all modules are loaded during system start.
* {kernelProcess, Name, {Mod, Func, Args}} starts a "kernel process". The kernel process Name is started by evaluating apply(Mod, Func,
Args) which is expected to return {ok, Pid} or ignore . The init process monitors the behaviour of Pid and terminates the system if Pid
dies. Kernel processes are key components of the runtime system. Users do not normally add new kernel processes.
* {apply, {Mod, Func, Args}} . The init process simply evaluates apply(Mod, Func, Args) . The system terminates if this results in an
error. The boot procedure hangs if this function never returns.
Note:
In the interactive system the code loader provides demand driven code loading, but in the embedded system the code loader loads all the
code immediately. The same version of code is used in both cases. The code server calls init:get_argument(mode) to find out if it should
run in demand mode, or non-demand driven mode.
