pass-backup

An extension for pass (the standard Unix password manager) to easily create backups of the password store.

Motivation

One should always do backups. So backups must be simple. Nothing more simple than typing pass backup.

Usage

Usage:

    pass backup [backuplocation]
        On the first run it creates a directory ".backups" in \$PASSWORD_STORE_DIR.
        By default this is ~/.password-store/.backups".
        It creates a backup of the complete password store by creating a
        compressed tar-file with extension .tar.bz2.
        Backups themselves are excluded from the backup.
        Without argument the backup file will receive the default name "passwordstore.DATE.TIME.tar.bz2"
        where DATE and TIME are the current date and time.
        If an argument is given and it is a directory, the backup file will be placed
        into the specified directory instead of the default ".backups" directory.
        If an argument is given and it is not a directory, it is used as a file
        name and the backup is stored with this filename with .at.gz2 appended.
    pass backup help
        Prints this help message.
    pass backup version
        Prints the version number.

Examples

Example 1: Using defaults, standard use

$ pass backup

This is the typical usage. This creates a backup and places it into $PASSWORD_STORE_DIR/.backups e.g. ~/.password-store/.backups/passwordstore.190407.122034.tar.gz2.

Example 2: Specifying a destination directory

$ pass backup Documents/Backups/

This creates a backup and places it into Documents/Backups/ i.e. Documents/Backups/passwordstore.190407.122034.tar.gz2.

Example 3: Specifying a destination file

$ pass backup Documents/Backups/mypassbackup

This creates a backup and places it into Documents/Backups/mypassbackup.tar.gz2.

Installaiton

For installation download and place this bash script file backup.bash into the passwordstore extension directory specified with $PASSWORD_STORE_EXTENSIONS_DIR. By default this is ~/.password-store/.extensions.

$ cp backup.bash ~/.password-store/.extensions

Give the file execution permissions:

$ chmod 700 ~/.password-store/.extensions/backup.bash

Set the variable PASSWORD_STORE_ENABLE_EXTENSIONS to true to enable extensions.

$ export PASSWORD_STORE_ENABLE_EXTENSIONS=true

Download and source the bash completion file pass-backup.bash.completion for bash completion.

$ source ~/.password-store/.bash-completions/pass-backup.bash.completion

Type pass backup to create your first backup.

$ pass backup

Requirements

• pass from https://www.passwordstore.org/
• tar to be installed for zipping and compression.

Notes

Both files are tiny: 142 lines (script) and 17 lines (autocompletion) respectively. You can check them yourself quickly. No need to trust anyone.
