rmcp uses the scp command to backup reMarkable files and directories by date over either USB or WLAN. It is written in Bash for a Linux machine, and, while it may work on MacOS, it most likely will not on Windows.

Note:: This script was made to replace the rmcp alias in the previous article, remember to remove it from your .bash_aliases file.

Backups by date over USB and WLAN

rmcp first creates a directory called unremarkable and a subdirectory, remarkable_backups, to store backups by date, after creating these directories it prompts the user for their tablet's IP address.

rmcp checks that the IP format is correct, and, if it isn't, prompts the user again. If it is, then rmcp creates the backup directory and attemps to copy files from the table with the scp commmand either over USB, if the IP address is 10.11.99.1, or WLAN otherwise.

Note:
: If you have many files on your tablet it is at least 5 to 10 times faster to backup over USB.
