Backup shell script to backup selected directories and upload securely (gpg) to FTP server

in Categories Backup last updated April 9, 2008

This script requires GNU Privacy Guard – cryptographic software on Linux / UNIX systems. GnuPG encrypts messages using asymmetric keypairs individually generated by GnuPG users. The resulting public keys can be exchanged with other users in a variety of ways, such as Internet key servers. They must always be exchanged carefully to prevent identity spoofing by corrupting public key ↔ ‘owner’ identity correspondences. It is also possible to add a cryptographic digital signature to a message, so the message integrity and sender can be verified, if a particular correspondence relied upon has not been corrupted.

GnuPG does not use patented or otherwise restricted software or algorithms, including the IDEA encryption algorithm which has been present in PGP almost from the beginning. Instead, it uses a variety of other, non-patented algorithms such as CAST5, Triple DES, AES, Blowfish and Twofish. It is still possible to use IDEA in GnuPG by downloading a plugin for it, however this may require getting a license for some uses in some countries in which IDEA is patented.

GnuPG is a hybrid encryption software program in that it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient’s public key to encrypt a session key which is only used once. This mode of operation is part of the OpenPGP standard and has been part of PGP from its first version.

Shell Script

#!/bin/bash
# Shell script (BASH) to backup the selected directory on server and upload to 
# another ftp server securely. This script uses the gpg command to 
# encrypt the .tar.gz file before upload take place. 
#
# In order to run this script you must have following tools installed:
# - /usr/bin/ncftpput
# - /bin/tar
# - /usr/bin/mail
# - /usr/bin/gpg
#
# Script also mails back the ftp operation failed or not
#
# Installation:
# Customize the script according to your need. You need to setup ftp 
# server, password etc. Next, you need to setup gpg user name and 
# import public key so that you can encrypt the files. Usually following two 
# commands needed for gpg:
# gpg --import userkey
# gpg --edit-key KEY_ID|USER_ID
# Command>trust
