backuptool

Create encrypted .tar.gz archives.

Requirements

• Python 3.5+
• python-gnupg

Functionality

• Create .tar.gz archives encrypted with GPG.
• Use symmetric or asymmetric encryption.
• Backup directories defined in a config file.

Usage

1. Clone the repository.

2. Run python create-backup.py to create a new config file:

   [SETTINGS]
   recipients = ["[email protected]"]
   gnupghome = "/home/user/.gnupg"
   
   [CRITICAL]
   directories = [
   	"/home/user/.password-store",
   	"/home/user/.gnupg"
   	]
   
   [IMPORTANT]
   directories = [
   	"/home/user/Pictures",
   	"/home/user/Documents"
   	]
   
   [NON_ESSENTIAL]
   directories = [
   	"/mnt/hdd/large-files",
   	"/mnt/hdd/movies"
   	]

3. Edit the values for your own use.

   Put your GPG email in the recipients field.

   There are three levels, critical, important and non-essential.

   • Critical is meant for files that absolutely cannot be missed, such as passwords. Mostly small files.
   • Important is for non-critical but still important and irreplaceable files, such as documents, pictures, etc.
   • Non-essential is meant for things that can be retrieved in some way, like movies, music, books, and downloads. Mostly large files.

4. Run python create-backup.py and supply the arguments you need. Example:

   • python create-backup.py -c would create backup file /tmp/backup-<date>.tar.gz.gpg, containing only critical files.
   • python create-backup.py -c -i -n would create a backup file containing critical, important and non-essential files.
   • python create-backup.py -c --symmetric creates a backup file using symmetric encryption. You will be asked to choose a password.

5. The backup is now complete.

   You can decrypt the resulting file using gpg --output <filename>.tar.gz --decrypt <archive_name>.tar.gz.gpg. Optionally append & progress -mp $! to that command to show progress.
