Encrypting Backup Files

netpumber · 01-18-2010, 10:52 AM

Halo!

I m going to create a backup script for my files/folders...

This script creates tar.gz of the folders/files you want.

This i want is to encrypt these .tar.gz files and when i need them to decrypt them. Does anyone have an idea on how to encrypt these files ?

my script looks like this :

Code:

BACKUPDATE=$(date +%d%m%Y)

cd /home/n3t

echo "taking Backup of your home/n3t/Downloads dir"
tar -czvf /media/disk/BACKUP/home/Downloads/$BACKUPDATE.tar.gz ./Downloads

Thanks for any answer

I recommend gnupg (as mentioned in the "file encryption" article above), or openssl's enc program.
