# backup

Backup helper for git, tarsnap, plakar and rclone. One command commits,
archives or syncs a named set of directories.

Needs `janet` plus whichever backends you use.

## Config

Targets live in `~/.config/backup/config.janet`. One Janet table. Paths may use `~/` and `$VAR`.
See `config.example.janet`.

Omit rclone `:targets` to reuse the plakar sources. Set `{}` to
disable rclone. Plakar stores and sources stay in plakar's own files.

## Usage

```sh
backup -l                       # list targets
backup git:notes                # commit, no push
backup -p git:notes             # commit, pull, push
backup tarsnap:notes            # timestamped archive
backup plakar:hoo               # back up every source to hoo
backup 'plakar:hoo:src,notes'   # back up two sources
backup rclone:notes             # copy to backup:notes
backup git -e notes             # all git targets except notes
```

One target per run. No target lists and exits.

## Options

- `-p`, `--push`: commit, pull, push git targets
- `-f`, `--fetch`: pull git targets first
- `-q`, `--quiet`: hide child output
- `-l`, `--list`: list targets
- `-e`, `--exclude`: names to skip
- `-h`, `--help`: usage

Failing targets get reported. The rest still run. Exit code is
nonzero if anything failed.
