timeshift的安装配置

安装并配置timeshift

安装

sudo apt install timeshift

完成之后看一下：

$ sudo timeshift

Timeshift v20.03 by Tony George (teejeetech@gmail.com)

Syntax:

  timeshift --check
  timeshift --create [OPTIONS]
  timeshift --restore [OPTIONS]
  timeshift --delete-[all] [OPTIONS]
  timeshift --list-{snapshots|devices} [OPTIONS]

配置

默认安装后，在第一次运行前，我们需要修改 timeshift 的配置文件，否则 timeshift 会默认找到一个 ext4 分区作为备份区。

看一下目前的硬盘情况：

$ sudo fdisk -l
Disk /dev/loop0: 55.45 MiB, 58130432 bytes, 113536 sectors
Units: sectors of 1 * 512 = 512 bytes

Device             Start       End   Sectors  Size Type
/dev/nvme0n1p1       256    131327    131072  512M EFI System

/dev/nvme0n1p3 196739328 219771391  23032064 87.9G Linux filesystem

这里的 /dev/nvme0n1p3 是我为 timeshift 预留的分区，存放在 nvme 磁盘上，以保证备份和恢复的速度。

$ sudo lsblk -f

记录 nvme0n1p3 的 uuid ，然后修改配置, sudo vi /etc/timeshift/timeshift.json 打开后设置 backup_device_uuid 为 nvme0n1p3 的 uuid :

{
  "backup_device_uuid" : "9b22569d-9410-48cc-b994-10257b2d0498",
  "parent_device_uuid" : "",
  "do_first_run" : "true",
  "btrfs_mode" : "false",
  "include_btrfs_home" : "false",
  "stop_cron_emails" : "true",
  "schedule_monthly" : "false",
  "schedule_weekly" : "false",
  "schedule_daily" : "false",
  "schedule_hourly" : "false",
  "schedule_boot" : "false",
  "count_monthly" : "2",
  "count_weekly" : "3",
  "count_daily" : "5",
  "count_hourly" : "6",
  "count_boot" : "5",
  "snapshot_size" : "0",
  "snapshot_count" : "0",
  "exclude" : [
  ],
  "exclude-apps" : [
  ]
}

执行timeshift命令，就能看到配置生效了：

sudo timeshift --list
