Daily backup of settings on FTP

Below is a description of the script, designed to save the settings of a group of master units on the ftp server.

Running the script is provided on the operating system of the user (administrator). To periodically run this script you need to use the task scheduler of your operating system (cron, anacron - for * nix, Task Scheduler, nnCron - for Win, etc.)

To run the script requires Python 3, the distributive which can be downloaded here: https://www.python.org/downloads/, or installed from the repository of your operating system.

To configure the script You must specify the parameters in the User settings tab:

Parameter	Function

Parameter	Function
^username	User account name with administrator privileges on the device
^password	User account password with administrator privileges on the device
^ftpurl	FTP server address
^ftpuser	FTP server user
^ftppassword	FTP server password
^ftpdir	FTP directory for copies of setting files

The list of monitoring units' IP addresses is defined in the file hosts.txt with one IP address on each line. For Example:

hosts.txt

192.168.0.193
192.168.0.194
telemetry.asia

Configuration files are stored on the ftp server in the specified directory as settings_mm.dd.yy-hh: mm: ss.vut

The text of the script is attached below:
