# A poor man backup
|
|
|
|
## Description
|
|
|
|
A simple wrapper script to create a safe and redundant backup
|
|
|
|
## Requirements
|
|
|
|
Requires: bash, GnuPG, duplicity, rdiff-backup, ssh, figlet
|
|
|
|
##
|
|
|
|
The script attempts 3 differents backup:
|
|
|
|
* to a SD card via duplicity, encrypted with gnupg. It prevents ransom-ware.
|
|
* to a remote Pc via duplicity and ssh, encrypted with gnupg. It prevents lost or damage.
|
|
* to a remote Pc with encrypted disk via rdiff-backup. Plain mirror for easy recovering.

Optional: copies selected config files in $HOME/backups
|
|
|
|
It is recommended to do a full backup every now and then, therefore the script ask you for
|
|
a full backup every 6 months, and ask to delete the old full backup every 7 months. Make
|
|
sure you have enough space for 2 full backups in your destination drive. A full backup
|
|
takes time, you better run it before going to sleep
|
|
|
|
Important: please remember to backup your gpg-private key separately because you will need
|
|
it to access the encrypted backup.
|
|
|
|
The script verifies that gpg-agent is running and mount the SD card, it is supposed to be
|
|
well-commented and intentionally is all manual. In case you wants to automatize you need
|
|
to setup ssh and gpg passwordless and add the script to cron.
|
|
|
|
my poor's man backup: hope you find this useful
|
|
To make it yours you need to customize your paths and your shouts
|
|
Good luck and may you never need to recover.
