rsync4backup.sh

#/bin/bash
## a simple bash script for copying a certain directory to a local folder, usb and or to a remote server
## this was mainly used to backup the directory of the frappe-bench sites.
## feel free to comment the part of the code that you don't want to use for backup.

## type the site name that you want to take its backup
## example: site1.local or erpnext_demo
site_name='site1.local'

## The folder in which we take backups from
source_directory=~/frappe-bench/sites/$site_name

## for backup to a local folder ---
## Where to save local backup, Note: this folder must already had been created using mkdir command
local_destination='~/backup_folder'

## for backup to a USB or to HDD ---
## Specify the USB/HDD directory name,Note: The format of the USB must not be FAT32
## this directory must already had been mounted to its corresponding /dev/sdX partition using mount command
usb_mount_directory='/media/USB/'

## backup to a Remote server ---
## change the below to your remote backup server
## ex: ibrahim@192.168.1.30:/home/ibrahim/
## Note: for this to work automatically use ssh-keygen and ssh-copy-id to your remote server first
remote_username='ibrahim'
remote_address='192.168.1.30'
remote_directory='~/'
remote_destination=$remote_username@$remote_address:$remote_directory
