Using restic and resticprofile to implement automatic backup

Table of Contents

Intro

我是一个爱折腾电脑的人，但是我只有一台电脑，最近差点把系统搞崩。那次教训让我深刻意识到数据备份的重要性。

在使用 restic1 之前我也尝试过手动备份，但是手动备份有几个缺点：

  1. 无法定时备份，完全依靠自身的习惯。在特别忙的时候容易忘记备份，这个时候恰恰也是最没有时间修复电脑的时候，出不得问题
  2. 如果只是单纯的复制粘贴，容易文件冗余，对硬盘空间要求大，其次复制时间长。

restic 是一个数据加密增量备份工具，可以做到对备份的数据加密，能够增量备份2，从而做到多份备份的同时占用空间小。

resticprofile3 是一个基于 restic 的自动化工具。

Prerequisite

  1. restic
  2. resticprofile

Get Started

实际上我们只需要配置好 resticprofile 就行了。

Make config

mkdir -p ~/.config/resticprofile/
touch profiles.toml

Setup config

version = "1"

[default]
  # local mean in backup in this computer
  repository = "local:/path/to/backup"
  password-file = "/path/to/password-file"
  verbose = true

[project1]
  inherit = "default"
  initialize = true
  [project1.backup]
    source = [
      "/path/to/source-file-1",
      "/path/to/source-file-2",
      "/path/to/source-file-3"
    ]
    # backup every day at 3 a.m.
    schedule = "03:00"
    schedule-permission = "user"
    schedule-lock-wait = "2h"
  [project1.retention]
    before-backup = false
    after-backup = true
    # keep the newest one
    keep-last = 1
    # keep the newest one in this week
    keep-weekly = 1
    prune = true

[project2]
  inherit = "default"
  initialize = true

  [project2.backup]
    prune = true
    verbose = true
    source = [
    # ...
    ]
    # backup every Monday at 4 a.m.
    schedule = "Mon 04:00"
    schedule-permission = "user"
    schedule-lock-wait = "2h"

  [project2.retention]
    before-backup = false
    after-backup = true
    keep-last = 1
    prune = true

Begin backup

resticprofile init
resticprofile --name project1 backup
resticprofile --name project2 backup

Set schedule

sudo resticprofile -c ~/.config/resticprofile/profiles.toml schedule --all

check

resticprofile -n default snapshots --latest 1
