autorestic

High backup level CLI utility for restic.

Autorestic is a wrapper around the amazing restic. While being amazing the restic cli can be a bit overwhelming and difficoult to manage if you have many different location that you want to backup to multiple locations. This utility is aimed at making this easier 🙂

📒 Docs

🛳 Installation

Linux & macOS. Windows is not supported.

curl -s https://raw.githubusercontent.com/CupCakeArmy/autorestic/master/install.sh | bash

🚀 Quickstart

Setup

First we need to configure our locations and backends. Simply create a .autorestic.yml either in your home directory of in the folder from which you will execute autorestic.

Optionally you can specify the location of your config file by passing it as argument: autorestic -c ../path/config.yml

locations:
  home:
    from: /home/me
    to: remote

  important:
    from: /path/to/important/stuff
    to:
      - remote
      - hdd

backends:
  remote:
    type: b2
    path: 'myBucket:backup/home'
    B2_ACCOUNT_ID: account_id
    B2_ACCOUNT_KEY: account_key

  hdd:
    type: local
    path: /mnt/my_external_storage

Then we check if everything is correct by running the check command. We will pass the -a (or --all) to tell autorestic to check all the locations.

If we would check only one location we could run the following: autorestic check -l home. Otherwise simpply check all locations with autorestic check -a

Note

Note that the data is automatically encrypted on the server. The key will be generated and added to your config file. Every backend will have a separate key. You should keep a copy of the keys somewhere in case your server dies. Otherwise DATA IS LOST!

📦 Backup

autorestic backup -a

📼 Restore

autorestic restore -a --to /path/where/to/restore

This will restore all the locations to the selected target. If for one location there are more than one backends specified autorestic will take the first one.

Lets see a more realistic example (from the config above)

autorestic restore -l home --from hdd --to /path/where/to/restore

This will restore the location home to the /path/where/to/restore folder and taking the data from the backend hdd

📲 Updates

Autorestic can update itself! Super handy right? Simply run autorestic update and we will check for you if there are updates for restic and autorestic and install them if necessary.

🗂 Locations

A location simply a folder on your machine that restic will backup. The paths can be relative from the config file. A location can have multiple backends, so that the data is secured across multiple servers.

locations:
  my-location-name:
    from: path/to/backup
    to:
      - name-of-backend
      - also-backup-to-this-backend

Pruning and snapshot policies

Autorestic supports declaring snapshot policies for location to avoid keeping old snapshot around if you don't need them.

This is based on Restic's snapshots policies, and can be enabled for each location as shown below:

locations:
  etc:
    from: /etc
    to: local
    options:
      forget:
        keep-last: 5             # always keep at least 5 snapshots
        keep-hourly: 3           # keep 3 last hourly shapshots
        keep-daily: 4            # keep 4 last daily shapshots
        keep-weekly: 1           # keep 1 last weekly shapshots
        keep-monthly: 12         # keep 12 last monthly shapshots
        keep-yearly: 7           # keep 7 last yearly shapshots
        keep-within: "2w"        # keep snapshots from the last 2 weeks

Pruning can be triggered using autorestic forget -a, for all locations, or selectively with autorestic forget -l <location>. please note that contrary to the restic CLI, restic forget will call restic prune internally.

Run with the --dry-run flag to only print information about the process without actually pruning the snapshots. This is especially useful for debugging or testing policies:

$ autorestic forget -a --dry-run --verbose

Excluding files/folders

If you want to exclude certain files or folders it done easily by specifiyng the right flags in the location you desire to filter. The flags are taken straight from the restic cli exclude rules.

locations:
  my-location:
    from: /data
    to:
      - local
      - remote
    options:
      backup:
        exclude:
          - '*.nope'
          - '*.abc'
        exclude-file: .gitignore

backends:
  local:
    ...
   remote:
    ...

Before / After hooks

Sometimes you might want to stop an app/db before backing up data and start the service again after the backup has completed. This is what the hooks are made for. Simply add them to your location config. You can have as many commands as you wish.

locations:
  my-location:
    from: /data
    to:
      - local
      - remote
    hooks:
      before:
        - echo "Hello"
        - echo "Human"
      after:
        - echo "kthxbye"

💽 Backends

Backends are the place where you data will be saved. Backups are incremental and encrypted.

Fields

type

Type of the backend see a list here

Supported are:

For each backend you need to specify the right variables as shown in the example below.

path

The path on the remote server. For object storages as

Example
backends:
  name-of-backend:
    type: b2
    path: 'myAccount:myBucket/my/path'
    B2_ACCOUNT_ID: backblaze_account_id
    B2_ACCOUNT_KEY: backblaze_account_key
