Coralbits Backup

Simple backup solution.

It has only three backup options:

1. Backup a directory
2. Backup stdout
3. Run pre and post commands

Over this it can encrypt the backups, with no unencrypted data ever written locally. So can backup directly to S3 (via https://github.com/kahing/goofys for example).

It has no knowledge of which file is where, nor tapes nor other backup specialized areas. It is just a simple backup.

Use example

Create a yaml file with your backup plan at backup-plan.yaml:

localhost:
  gpg_key: mygpgkeyid
  paths:
    - /home/

This plan means just to connect via SSH to localhost, and do a tar.gz of /home/. Directories end in /, files do not.

To execute run:

./cbackup.py /var/backups/

By default it will use the backup-plan.yaml file, but can be overriden with the --plan option.

If you want an incremental backup, you can add -i for changes since yesterday, same time, or --since [days] to get all changes since that many days ago.

The files will be a concatenation of the date, hostname, and the path.

More examples in the example.yaml file.

Options

$ ./cbackup.py
backup.py -- Simple backups -- v%(version)s

Run:
  backup.py [options] <destdir> [hosts]

  [options] are optional
  <destdir> is mandatory, and backup will create files based on the
            date, hostname, dir/file
  [hosts]   optional host list. If not exists, will use all from
            `backup-plan.yaml`


Needs a backup-plan.yaml with:
  default: {pre, paths, post, mailto, smtp}
  hostname: {pre, paths, post, mailto}

  `default` will be executed for all hosts.

Where {pre, backup, post} are lists of:
  `pre`    commands to execute on the remote server before backup: setup
  `paths`  directories (end with /) or files to backup
  `post`   commands to execute on the remote server after backup: cleanup
  `stdout` dictionary of command to capture stdout for backup, for example pg_dump
  `email`  Comma separated email address to send an email on completion. Can
           set a file name to keep a local copy.
  `smtp`   hostname, port, tls, username and password for email sending.

Options:
    -h    | --help           -- Show this help
    -v    | --version        -- Shows current version and exits
    -i    | --incremental    -- Only changes since yesterday
    --since=days             -- Only changes since `days` before. Can be float.
    --dry | --simulate       -- Say what will be executed, but do not execute
    --full                   -- Full backup (default)

Recover

Thats on you. Its is just a simple tar.gz.gpg.

Roadmap

I really want to keep it simple, but these features would be cool to have:

• [host].host to be able to do backups on other host, not the name of the backup.

Thats all!
