+## Remote Server Backup Script
+## Author: Ze'ev Schurmann
+## Reddit: u/thisiszeev
+## License: GPL-3.0 or later
+
+## This script can only backup one server. So you need a seperate folder for each server. Put this file in each folder and apply
+## the relative settings to each server. If you want to get Telegram notifications then check the API documents on the Telegram
+## Website. Use a cron job to schedule each run. If you have more than one server, then stagger them. If you are backing up to a
+## local machine that is not on redundant power, schedule each backup to run more than once a day, just incase of a power failure
+## during a backup. The script will know if the last attempt was successful or not.
+
+## Dependancies:
+## rsync, ssh, tar, gzip, wget
+## make sure you have key pair authentication setup for ssh. Rsync must be installed on both the remote server and the local machine.
+
+## Use the SQLDumps script to export all MySQL and MariaDB databases on the server. Ensure the SQLDump runs long before this script
+## runs to ensure that all databases are completely dumped.
+
+## Example crontab entries (exclude the ##)
+
+## 30 2    * * *   root    cd /media/backupdrive/server1 && bash backup.sh
+## 30 5    * * *   root    cd /media/backupdrive/server2 && bash backup.sh
+## 30 8    * * *   root    cd /media/backupdrive/server1 && bash backup.sh
+## 05 11   * * *   root    cd /media/backupdrive/server2 && bash backup.sh

+## 30 17   * * *   root    cd /media/backupdrive/server2 && bash backup.sh

+## Please consider making me small donation. Even though my scripts are open source and free to use, I still need to eat. And the
+## occasional bottle of wine also goes down well.
+## $5 buys me a cup of coffee
+## $10 buys me a nice burger
+## $20 buys me a bottle of wine
+## Anything above that will be awesome as well.

+## Telegram API and Channel Settings
+
+## Set usetelegram to true to get sent Telegram notifications. The Telegram API documentation covers how to obtain a bot key and how
+## to assign the bot to a channel. Channels are used as it means notifications can be sent to more than one person if they are all
+## in the same channel.
