New Around Here
Hi, I'm very new to ASUS-Merlin, as I just installed it on my ASUS RT-AC87U this past weekend.

How can I learn about installing a script onto my router, that will copy one attached USB Device (USB1) to a second attached USB Device (USB2)? I want the router to do this automatically at 3 am, daily. I plan on using XCopy from a Windows 10 computer to update USB1 with the client's local files as soon as a network connection is established at bootup.

This is a sample of the xcopy script that I will be using from client to USB1. I want the script from USB1 to USB2 to have the same or similar parameters.

/D:m-d-y    Copies files changed on or after the specified date. If no date is given, copies only those files whose source time is newer than the destination time.
/E  Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T.
/C  Continues copying even if errors occur.
/Q  Does not display file names while copying.
/H  Copies hidden and system files also.
/R  Overwrites read-only files.
/K  Copies attributes. Normal Xcopy will reset read-only attributes.
/Y  Suppresses prompting to confirm you want to overwrite an existing destination file.

Any help anyone can provide to me would be great. Thank you.

I admire your willingness to learn. That said, if you are just starting with Linux, then there is really not a good simple straight forward answer to give you. There is a couple of ways you can go to accomplish this (dd, rsync, cp, tar, etc). As far as scheduling the job, you will need to add a cron job via a user script.
