Create encrypted .tar.gz archives.

Primary LanguagePython

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 = ["user@email.com"]
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.
