You can download SyncBack Touch and check the prerequisites for Linux at the link below:
The downloaded file is a standard zip file which contains an executable binary. After extracting the zip file, you will need to give the binary file the execute permission (+x) using the chmod command line tool (e.g. chmod +x SyncBackTouchLinux) and then run it by entering "./SyncBackTouchLinux" (without quotes) from the terminal command line. Once started, SyncBack Touch will run in the background.
For command line parameters on how to change the password and the listening port run the program with the -help parameter to see the list of supported parameter settings (e.g. ./SyncBackTouchLinux -help).
