 # Mikrotik RouterOS automatic backup and update
 
-This script provides an ability to create Mikrotik's daily backups to email. You can also enable automatic RouterOS upgrade or leave only notifications about new firmware versions.
-
-
+This script allows you to generate daily backups of MikroTik and send them to an email address. You can also choose to enable automatic RouterOS upgrades or receive notifications exclusively for new firmware versions.
 > 💡 If you have any ideas about the script or you just want to share your opinion, you are welcome to [Discussions](https://github.com/beeyev/Mikrotik-RouterOS-automatic-backup-and-update/discussions), or you can open an [issue](https://github.com/beeyev/Mikrotik-RouterOS-automatic-backup-and-update/issues) if you found a bug.
 
 
 ## Features:
-- Ability to choose script operating mode according to your needs. *(Read below)*
-- Script creates backups of the whole system and exported config.
-- You can set a preferred update channel.
-- If automatic updates are enabled, you can set script to install only patch versions of RouterOS updates. *This means if the current RouterOS version is v6.43.6, the script will automatically install v6.43.7 (new patch version) but not v6.44.0 (new minor version), for example.*
-- Script includes primary information about the device into the email message. So you can easily find the backup you need among multiple devices.
-- For safety purposes, an automatic update process will not be started if script could not send backups to email.
-- Routerboard firmware can be automatically upgraded according to the installed RouterOS version.

+- Select the script's operational mode according to your specific needs (details provided below). 
+- This script is designed to create full system backups and export configurations. 
+- Customize the update channel according to your preference. 
+- With automatic updates activated, the script can be set to apply only patch updates for RouterOS. For instance, should the current RouterOS version be v6.43.6, the script will autonomously upgrade to v6.43.7 (a patch update), while avoiding v6.44.0 (a minor update).*
+- The script also incorporates vital device details in the email alerts, facilitating easy identification of the necessary backup among several devices. 
+- For added security, the script is programmed to stop the automatic update process if it fails to dispatch backups via email. 
+- Routerboard firmware can be upgraded automatically based on the installed RouterOS version.
 
 ## Script operating modes:
-**Backups only** - script creates system and config backups and sends them to specified email as an attachment. Using email account as storage for your backups.  
-**Backups and notifications about new RouterOS release** - Except backups, script also checks for new RouterOS firmware release and provides this information in the email.  
-**Backups and automatic RouterOS upgrade** - Script makes a backup, then checks for new RouterOS version, and if new firmware released, script will initiate upgrade process. By the end, you receive two emails. The first one contains system backups of the previous RouterOS version, the second message will be sent when the upgrade process is done (including backups of the updated system).
+**Backups only** - The script generates system and configuration backups and forwards them to a specified email as attachments. It uses your email account as a storage for these backups.  
+**Backups and notifications about new RouterOS release** -  In addition to creating backups, the script also monitors for any new releases of RouterOS firmware and communicates this information via email.  
+**Backups and automatic RouterOS upgrade** - The script begins by creating a backup, followed by a check for any new versions of RouterOS. If a newer firmware version is detected, the script initiates the upgrade process. Upon completion, two emails are sent: the first includes the system backups from the prior RouterOS version, and the second, sent post-upgrade, contains backups of the updated system.
 
 ## How to use
 > ❗️ **Important**  
-> Make sure that your device identity does not contain any spaces or specific symbols! `System -> Identity`
+> Ensure your device identity does not contain spaces and special characters! `System -> Identity`
 
 ##### 1. Configure parameters
-Take the  [script](https://github.com/beeyev/Mikrotik-RouterOS-automatic-backup-and-update/raw/master/BackupAndUpdate.rsc) and configure it's parameters at the begining of the file.  
-This is not difficult because all parameters are well commented.  
-**Important!** Don't forget to provide correct email address for backups and pay attention a `scriptMode` variable.

-When everything is done, you need to make sure that the script is working correctly.  
-To do so, open a New Terminal and Log window in your WinBox, then run the script manually by executing this command `/system script run BackupAndUpdate;` in Terminal.  
-You will see the script working process in the log window. If the script finished without errors, check your email, there is a fresh message with backups from your MikroTik waiting for you 🎉
