bacpac

bacpac is a backup and restore script for Arch Linux's pacman configuration data and manually installed packages.

Dependencies

• bash for the script itself
• git and diffutils for backing up current packages and configuration
• sudo and grep for restoring packages and configuration
• ...that's all!

Getting started

Setting up bacpac for the first time is super-easy; the only requirement is a GitHub account to sync your packages. To get started, read the following instructions:

1. Create a GitHub account if you don't already have one.

2. Fire up a terminal.

3. git clone https://github.com/tech4david/bacpac

4. cd bacpac

5. ./bacpac init

6. Follow the instructions displayed on the terminal.

Please report any issues you find with bacpac here or submit a pull request.

# SigLevel    = Required DatabaseOptional

# NOTE: You must run `pacman-key --init` before first using pacman; the local

#
# REPOSITORIES
#   - can be defined here or included from another file
#   - pacman will search repositories in the order defined here
#   - local/custom mirrors can be added here or in separate files
#   - repositories listed first will take precedence when packages
#     have identical names, regardless of version number
#   - URLs will have $repo replaced by the name of the current repo
#   - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
#       [repo-name]
#       Server = ServerName
#       Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#

# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.
